This is not only first issue of the year 2009 butit’s also first Druppel of new Druppel committee. Weworked hard on it and sometimes some trouble blindsidedus due to the lack of experience with this job. Weenjoyed time spent on this Druppel and we hope thatyou will like this Druppel and will look forward to readingnext one.You can read something about activities that took placesince November 2008. We pay attention to two companycases which occurred in last three month and whichall participants enjoyed a lot. You can also read somearticles which were written by teachers and staff of watermanagement department, something about comingEbro study tour, about master thesis of our colleaguesfrom water management department and other interestingreadings.According to the feedback which we and previous DruppelCommittee have received (and hopefully we will stillreceive) we have decided to increase number of “technicalor scientific” article but don’t worry Druppel is stillhere for fun. It’s included little bit in coming Druppelbut we hope that the change will be recognizable innext Druppel. That’s why we decided to establish fromnext Druppel “Special.” The “Special” will focus on onetopic that relates with water management. The “Special”topic is known but we don’t proclaim it yet. Let’ssay that it’s our commercial trick. As we said beforewe would like to receive any feedback so if you haveany idea about “Special” or about anything else how tomake Druppel better don’t hesitate to contact us.Finally, we would like to thank to all contributors to thisDruppel without their help this Druppel couldn’t havebeen published.Enjoy reading and see you around!Rostislav Peknice on behalf of the Druppel committee.2

From the boardBy Philip Stive and Nicolaas van BalkonIt has been quite some time since the previous issue ofthe Druppel came out. During this time span a lot hashappened.The first and also biggest thing that happened justafter the publication of the previous Druppel was ofcourse the board change. The board of the Dispuutchanges every 6 months, three board members leave,three stay and three new ones arrive. Currently you aredealing with the 44st board, which consists of:Nikolaas van Balkom:PresidentPhilip Stive:SecretaryRobin Harder:TreasurerNadia Lugt:Commissionaire of EducationJan Talsma:Commissionaire of StudentsMarieke de Goede: Commissionaire of Public RelationsThe board change lunch was of course, like always,very well attended. Van Dijk and Savenije gave a nicespeech and everyone seemed to really enjoy. They alsoraised the new professor Jules van Lier on the table, soeverybody was up to date about everything that washapping at the department. The board change alwayscoincides with a general meeting, this however was notthat well attended. Maybe next time we should havelunch during the general meeting…During this very interesting meeting, Nikolaas declaredhis plans for the coming 6 months. This included moredrinks, more cookies, more fun. Now we are happy toannounce that we already had 200% more drinks thanprevious year, that on average we eat 100 cookies eachcookie break and since we have our mug-rack the dispuutsroomis very well visited. So please keep visitingour socials and if you do not have yet your mug, cometo the dispuutsroom to collect it and put it on the mugrack.Of course fun and social activities are very important,also our professional activities are important for ourfuture. The Dispuut has always been the gateway forcompanies to the students. Therefore we organize a fewcompany cases each year. In the previous four monthswe had a DHV and Witteveen+Bos company case. Bothtimes we sent around 20 students to express their talents.An extensive overview of these company casescan be found on page # and page # respectively.The board is very happy that we have a lot of activemembers. Active members are most of the time workingin committees. Throughout the year, committeesare always working really hard to organize certain returningevents. Currently these are the MDE and Symposiumcommittee. The MDE committee is doing reallywell, nearly everything has been arranged for a verynice one week trip in the May vacation. Because there astill 3 spots available, a short article about the trip canbe found on page #.The symposium committee was also working reallyhard, but due to an unfortunate combination of circumstancesthe planning of having the Symposium in Aprilwasn’t possible. The Symposium is now postponed toSeptember 2009. After all, it is better to have a goodSymposium later, than a bad Symposium earlier. Imageis very important, as has been illustrated during thecredit crisis the past months. More on the subject ofthe Symposium can be found on page #.Another important committee that deserves her ownparagraph is the Druppel committee. Since this year aspecial committee was formed to create the Druppel.This was done because the Druppel transformed intoa very high quality magazine over the previous years.To ensure this quality a lot of time and effort goes intothe Druppel. So much time that the board didn’t havetime for his normal tasks. To maintain the high qualitya Druppel committee was founded. We hereby like tothank all the Druppel committee members for all theeffort they have already put into this Druppel and aregoing to put in the coming Druppels! We actually want4

to thank all active members, because we cannot do itwithout them. And to all non-active members: you canbecome active… come over to the dispuutsroom for achat, cookie and coffee.Last but not least the board has a small problem. Maybeyou can help to solve this problem for us..:As everybody knows in the ‘coffee/lunch corner’ on the4th floor, we have some nice plants. At the momentthese plants suffer from great drought. You probablythink, give them some water problem solved. But recentlythe course irrigation and drainage was given, sowe think a future-water-manager, can do this wateringa bit more advanced. So therefore we offer a PRICEfor the one that designs the best irrigation system forour plants. Of course the water-bar and his pump canbe included in this design. Suggestions can be sent todispuut.watermanagement@ct.tudelft.nl.We want to end this story with an overview of the mostimportant water management events:MDE (To spain!)24th april to 3th of mayBorrelAprilCookie breaks4th period every Wednesday (10:30 10:45)Board change6th of maySollicitatie training eco jobs28th of may(hand in CV before 18th of may more info willfollow, drink)SymposiumSeptember5

a few years of, preferably international, experience.”Since I didn’t want to join small NGO’s (because thanI would become an expert directly, not having peoplearound me that could give feedback on my engineeringpractise), I started applying at engineering firms. ThereI could start building experience and expertise.I selected three firms, of which Witteveen+Bos andRoyal Haskoning seemed to have the biggest chance.During the application process I focused on the possibilitiesto work internationally and the development ofmy sanitary engineering skills next to my expertise inwater resources management.Engineering firms are not much different than NGO’sconsidering international practise. ‘Experience’ is theirkeyword as well. However, Royal Haskoning was differentAt the International Water Resources and Ecologydepartment, I did my thesis research. There I had tocolleagues that just finished their study. And after mygraduation, I had the chance to do a small project inTrinidad. Unfortunately, the situation at the departmentdid not allow giving me a longer term contract. Anyway,the head of the department would recommendme to any other department within Royal Haskoning.And he whispered: “if there is a project I can use you,I’ll let you know, but no guarantees.”projects at Amsterdam International Airport Schiphol,as well as in projects on creek rehabilitation.Since January I am also involved in a waste water engineeringproject. And, it is international! From Marchto September 2009 I will be resident engineer for theconstruction of the first waste water treatment plant inMali. It is a clear case of applying my engineering skillsin a developing country. And I will develop myself bygaining international experience, improving my sanitaryengineering skills, learning to speak French on amore professional level and most probably much more.A dream is going to come trueGeertjo van Dijk,Hydrologist at Royal HaskoningFinally, I applied at departments with a Dutch focus.Witteveen+Bos offered me a job in drinking water, RoyalHaskoning in water resources management. It was achoice for either development in sanitary engineeringor a gamble for doing international projects once in awhile. And more in the margin, it was the choice betweenliving in Deventer or Amsterdam.The choice I do not regret, was for the Water Resourcesand Ecology department of Royal Haskoningin Amsterdam. Now I live and work in a great city. Mydepartment has a great atmosphere with many youngpeople and enough seniors to learn from.The work I do is pretty broad, from urban to ecologicalwater management. For example I am involved in7

Dogged does it (de aanhouder wint)By Peter-Jules van OverloopIn 1995, I would have said: “Listen. It is not possibleto design a water system in such a way that it functionsproperly over a wide range of working point. Forgetabout steady state calculation and fixed structures.Think dynamics, flexible, adaptable. Use monitoringand prediction systems to estimate the present and(near) future state of the water system, and if this deviatesfrom the desired state, change the setting of thegates and pumps to steer it back. We have so many ofthese controllable structures in The Netherlands!”. Thepeople outside of our small operational water managementgroup would look puzzled and continue mindingtheir own business.In the year 2009, after more than a hundred evangelisticpresentations at municipalities, water boards andRijkswaterstaat, all is different. Policy makers and engineersrealize that we have reached the limits of patchinglocal problems. Instead, there is a shift towards amore integrated approach. Finally…Of course, we have an enormous lead here and directlygrab the opportunity to push the limits. The Delta Committee,preceded by Cees Veerman, promotes regionalintegrated solutions for solving the challenges for thenext 100 years. We opt for a national approach!Here’s the challenge: What if we can collect all objectivesof the Dutch Delta and would be given centralizedcontrol over all structures, could we come to a multiobjectiveoptimal behavior all year round? And whatif we take the climate change scenarios into account?And what if we were permitted to spend 10 billion Euroson a limited number of extra controllable structuresor bypasses anywhere in the country?What do you think? If you think we could be sitting ona pot of gold here, I would like to talk to you. If youthink it is not feasible, I want to talk to you even more.For this reason, I would like to invite you all for an upcomingbrainstorm session.Anyway, we were granted a first token of appreciation.Rijkswaterstaat has indicated this research to be innovativeand has donated a grant of almost 200.000Euro. And of course, the second one is a great honortoo: Writing an article in ‘’De Druppel’’.9

Discovering the world of infiltration facilitiesBy Leon ValkenburgMy scientific journey towards graduationthat’s called MSc thesisWriting your MSc thesis can actually be pretty boring,but at the same time it can also be very interestingand exciting. Sounds a bit weird? Well, welcome to theworld of graduating. In this article I hope to give yousome insight in my MSc research and the scientific experiencethat comes with it.First some background about my thesis topic. We allhave seen the articles in the newspapers and on thenews on pluvial flooding (Dutch: wateroverlast), especiallyduring summer. As a consequence the perceptionof the public is that flooding is increasing in frequency.The public demands action, so municipalities want andneed to take measures. A measure that has been increasinglyapplied since the nineties is disconnectingpaved areas (Dutch: afkoppelen) from the sewer system.Overloaded sewer systems are identified as oneof the main causes of pluvial flooding, so reducing thesurface area connected means reducing the load onthe system. One of the methods used is infiltrating therunoff from the disconnected paved areas in trenchesor subsurface systems of plastic infiltration units. Theproblem with these infiltration facilities is that they stillare designed in a very simplistic way.In September my research started. At the start of yourthesis nobody tells you how to do a research, so basicallyyou have to find out along the way. So whatdo you do first? A literature review! Although doing itis all but exciting, interesting things can already comeup during a literature review. To make things bit moredynamic, I also planned some interviews with peoplefrom the world of infiltration facilities.The literature review consisted of scanning and readingall relevant scientific journals and (simple) designguidelines for infiltration facilities from different countries.The goal was to find out how the infiltration facilitiesare currently designed in the Netherlands andPluvial floodingSo how did I get involved in this? When the last examhad finally passed, I started looking for a nice thesistopic, preferably with a company. I got into contactwith DHV and after a short brainstorm they offered meto do my thesis on the design of infiltration facilitieslinked to a client of theirs. A nice opportunity, so aftersome thinking, I agreed.abroad and what scientific research had been done onthe design and performance of the facilities in practice.The thing that struck me most during the literaturereview is that using although infiltration facilities areused more and more, the design of infiltration facilitiesis still based on the methods and assumptions developedin the old days. And these methods are ugly, scientificallyspeaking. There are many uncertainties and10

assumptions included in the design method, while it isunclear how facilities really perform. They can either betoo small or to big. To give an example: the design ofan infiltration facility is mainly based on the infiltrationrate, the amount of water the infiltrates into the soil. Inthe design guidelines the infiltration rate is calculatedwith Darcy’s law, which should not be used because itis not applicable to infiltration. Another assumption isthat the bottom of a facility should not be taken intoaccount due to sedimentation and clogging by the sediment.However I could not find clear scientific evidencefor this assumption. Funny thing is that the assumptionwas introduced by a Swedish professor in 1984 and hashardly been questioned since then.The interviews with people from the world of infiltrationfacilities basically backed up the impression fromthe literature review. There are millions and millionsinvested each year in infiltration facilities in the Netherlandsalone, and it is all but clear how they actuallywork. Hardly any municipality does some monitoring;of 41 municipalities contacted, none reacted positively.“Well, we don’t get any complaints, so they are working”is an often heard response. Of course it is an understandablereaction. However as the concept of thefacilities is really valuable, the design and managementshould be taken more seriously to justify the moneyinvested in them.that is a bit less ugly.The Hydrus 2D modelThe thing I find the hardest in my research is to produceresults and conclusions which are scientifically correct.Science for me is really the boring part. Anyway, assome pointed out the TU Delft is not called universityfor nothing, so let’s do it scientifically then. To comeback to the research, I hope to fill in the uncertaintiesin the design methods by modelling the infiltrationfacilities in an unsaturated zone model called Hydrus2D and by doing measurements in facilities in practice.This work is still progressing and gives and willgive some interesting results. I won’t tell too much, butI hope that it will stop freezing so water will actuallyflow, and when I am finished, I hope to start a Hydrus-2D fan club, because it has helped me so much. By thetime you read this article it should be near the date ofmy presentation, so you are welcome to join it and seemy results!Now knowing this, what’s next? I will keep it a bit short,because it is becoming a long story already. At the momentthe current design approach is clear and the assumptionsin the method have been identified. Thechallenge is to fill in or correct the assumptions if possible.In the end it should result in a design approach11

Ebro TourBy Anke PoelstraThis year, the More Days Excursion of the dispute willgo to Spain. If you are interested in water managementmethods in a dry country in combination with a lot offun with your fellow students than you should sign infor this beautiful trip!During the trip, we will visit Zaragoza and Barcelona,two of the most beautiful cities of Spain. From thesebases, we will visit several projects in the near vicinityof the Ebro river.The projects are chosen in order to facilitate for everydirection of our Master. We will visit a drinking waterplant, a desalination plant, the water board responsiblefor the Ebro and possibly the estuary of the river.Fortunately, there will plenty of time to visit the two citieswe will be staying at, since not only the weekends,but also Friday May first is a national holiday.So, if you are interested in a study tour that combinesseriousness with fun, sign in now at the dispute’s roomk.4.75.The Ebro committee12

TRANSBOUNDARY WATER MANAGEMENT IN SPAINBy Erik MostertHydropowerTransboundary water management is an important issuefor Spain. Spain shares several river basins withPortugal, the most important being the basins of theDouro, Tejo and Guadiana. In addition, there are somesmall transboundary rivers in the Pyrenees. A key problemis water scarcity, especially in the South.The Boundaries Treaty between Portugal and Spainof 1864 is the first international agreement that mentionsthe rivers that constitute the boundary betweenPortugal and Spain. The first agreement dealing specificallywith water is the Convention to Regulate theHydroelectric Use of the International Reaches of theRiver Douro, signed in 1927. In 1964 the principles andregulations of the 1927 agreement were extended tothe tributaries of the Douro and in 1968 to the internationalreaches of Minho, Lima, Tejo, Guadiana andChança River. According to the last agreement, Spainand Portugal are to share the hydroelectric potential ofthe boundary rivers on a 50-50 basis.This focus on hydropower development may come asno surprise. Since the end of the 19th century, largescaleriver basin development was seen as an importantmeans to “regenerate” the country. Environmentalissues did not get much attention. In the 1970s and1980s, however, water quality and water scarcity gotmore attention because of the large increase in irrigatedagriculture in Spain, increasing industrialisationand the discharge of untreated municipal sewage.The Albufeira ConventionIn 1993, the publication during one of the most severedroughts of this century of draft strategic guidelinesfor the Spanish Water Master Plan caused a stir. TheSpanish National Water Plan would involve the transferof large amounts of water from the humid north to thedry south. This would reduce the possibilities for futurewater resources development in Portugal. Portugalwas especially concerned about water supply to theAlqueva reservoir on the Guadiana River that it plannedto build. This reservoir has now been completed and isthe biggest reservoir in Europe.In 2000, the new socialist government of Spain cancellednearly all river transfers, but in the mean timenegotiations had started on a new convention, and on30 November 1998 the “Convention on Co-operationfor the Protection and Sustainable Use of the Watersof the Portuguese-Spanish River Basins” was signedin Albufeira. The Albufeira Convention anticipated theEuropean Water Framework Directive (2000/60/EC)and pays attention to both water quantity and quality.Moreover, it sets up a bilateral commission, whichwas meant to function as a medium for information exchange,for consultation on new projects, and for preparingjoint technical, legal, administrative measures.The commission has, however, not been very active.Concerning water quantity the convention containsthe general (but abstract) principles of internationallaw of “reasonable and equitable water use” and of“not causing significant harm.” In addition, the conventionguarantees minimal flows into Portugal in normalyears. Portugal considers these to be too low. For theGuadiana River, the guaranteed flow is 600 hm3/ year,which is exactly the same as the planned water suppliesfor irrigation form the Alqueva reservoir.In dry years the principle of not causing significantharm applies. This principle is interpreted to meanthat at least the ecological minimum flows should beguaranteed. These have not yet been agreed upon, butaccording to the proposal they would amount to onethirdof the average flow and equal or even exceed theflows that are guaranteed in normal years.EuropeIt is important to note that minimum ecological flowsare no longer an exclusively national or bi-national affair,but also a European affair. According to the WaterFramework Directive, which was adopted in 2000, EUMember status have to achieve in 2015 a “good waterstatus”, including a “good chemical status” and a14

“good ecological status” (there are some exceptions).Moreover, Member States have to prepare river basinmanagement plans every six years. In international basinsthese plans should be international or, if this is notfeasible, cover at least the national parts of the basinsand be coordinated internationally. Moreover, MemberStates have to develop national programmes for reachingthe environmental objectives and coordinate theseprogrammes among each other.The draft plans and programmes should have beenready on 22 December 2008 and should be adoptedone year later, on 22 December 2009. The EuropeanCommission controls the implementation of the WFDand other directives. If it thinks that implementation isnot done correctly, it can start an infringement procedureand eventually the European Court of Justice mayimpose heavy fines on the Member State(s) concerned.And this is not mere theory, it happens in practice.It would be interesting to see whether Spain (andPortugal) have met the 22 December 2008 deadline,whether they have made international plans or coordinatedtheir national plans effectively, and if so, whatthey have agreed upon. I will not hazard a guess. In anycase, “Europe” has changed the setting of transboundaryriver basin management in Spain significantly.SourcesCorreia, F. N. 1999.

AustraliaBy Cheryl Bertelkamp and Stijn de JongG’Day Mates!!When we arrived in Melbourne on the 27th of Januaryit was the beginning of a heatwave with 6 days in a rowtemperatures around 45 degrees. There has not been aheatwave of such severity since the keeping of recordsbegan 150 years ago. Quite a shock to go from minus2 to plus 45 within 24 hours.The first day in Melbourne we were faced with a jetlagand the great heat which was quit challenging. Wewalked through Melbourne to make arrangements forour visa and headed of to the Australian Open. Oncearrived, we were approached by a couple who offeredus their tickets to go in. The next minute we werewatching the match of Verdasco versus Tsonga on theeight row of the Rod Laver Arena! It appeared to be thebest place to be during a very hot afternoon.Just one week after this heatwave on the 7th of Februarythe temperature went up to 47 degrees again andthere was a very strong wind; a deadly combination.That weekend there were more than 400 bushfires inVictoria that were fed with the dry plants and fannedby the strong dry wind. This ‘Black Saturday’ probablycaused more than 300 casualties and destroyed manyhouse, whole villages are wiped off the map and manyacres of forest burned down.The Victorian Bushfires are a direct result of the currentperiod of drought Victoria is facing, the drought is oftenreferred to as ‘drought of the century’, ‘the most severedrought since Federation’ or ‘The Big Dry’. Since 1997the yearly rainfall was below average, a situation thathas created severe water shortages.While the Netherlands have plenty of water and aremost of the time thinking of ‘pompen of verzuipen’, Victoria’schallenge for water creates a completely differentlearning environment. Our internship is a collaborationbetween Deakin University in Geelong and ColibanWater in Bendigo. Both the internships are of courserelated to the drought.The development of the Bendigo region started in1851, right after the discovery of gold. The gold rushescaused an explosive population growth in the area,which resulted in major problems with the water systemin the area. The water system in the region transformedseveral times to supply the region with enoughwater for urban and rural use and for the gold miningindustry.At this moment the region is facing large problems concerningwater, due to the current drought.Since 1992 Coliban Water is in charge of the water supplyin the region and is now facing various challengesto its future water security. The biggest challenges includepopulation growth, the uncertainty of global climatechange, successive years of below average rainfalland stressed rivers.Coliban developed a model to check the water balanceof the region. This model will be used to determinewhere the biggest losses are in the system. This will beused to asses which parts of the system are the mostinteresting to improve. Nevertheless the model is notworking properly at the moment. At this moment themodel shows system efficiencies of 110%. It is not verylikely that the system is really possible to make waterand therefore the main objective for Stijn is to find outwhat is wrong with the model and try to improve it.Due to the drought, Australia is forced to recycle water.At the Bendigo Water Reclamation Plant, Coliban recycleswastewater to class A water which can for examplebe used to irrigate fields or to refill ponds. To recyclewater the wastewater treatment was extended with aWater Factory. The Water Factory contains two treat-18

ment trains. One treatment train consists of ultrafiltrationfollowed by reverse osmosis. The second trainconsists of chlorination, UV disinfection and dechlorination.High ammonia concentrations in the feed waterof the Water Factory cause problems in the treatmenttrain of the chlorination, UV disinfection and dechlorination.Coliban concluded that the Biological NutrientRemoval (BNR) process is the cause of these highammonia levels. With data provided by Coliban, Cherylshould make clear if this is indeed the problem and/orif there are any other problems.kangaroos, spot koalas or see the smallest pinguins onthe world coming across shore at Phillip Island.The very nice people, the beautiful nature and the currentproblems with water, makes Australia a very interestingplace to spend time during your study. So if youhave the opportunity, we really recommend it!Cheers!Cheryl and StijnAlthough we are very busy during the week we try tosee as much as possible in the weekends.

Company case DHVBy Arend van Breukelen (Student) and Annemieke van Doorn (DHV)On the eleventh of December a group of students werehuddling in the cold on the Delft station. It was a quarterto 8 in the morning and a delegation of the watermanagementdispuut was preparing itself to go toAmersfoort and visit with DHV.After buying some coffee and our tickets we got onthe train for a aleepy one and a half hour journey. InAmersfoort we were picked up from the station by theDHV’s company bus to take us the final miles to themain office.First we had a short walk through DHV’s gardenlikeoffices before being welcomed with a round of coffee.Piet van Helvoort, the Director DHV Water opened theday. He explained us how DHV is an engineering andconsutancy firm operating in about 30 countries andemploying 4700 people all over the world. He also discussedsome of DHVs previous and current projects.His presentation was followed by a couple of shortpresentations from young engineers from Delft andWageningen about working at DHV, internships andcareer opportunities. Leaving the introductions behindus, we were about to start with the Company Case. Thecase we were going to handle was an actual case DHVis working on (See box).The Hoogheemraadschap of Delfland has, in cooperation with the municipality of Delft, decided to executea ‘Water area study’ (Watergebiedsstudie, WGS) for the urban area of Delft. This study is actually a DesiredGround and Surface water Regime (Gewenst Grond en Oppervlaktewater Regime, GGOR) for urban areasthat also gives attention to the interaction with the sewage system and in which the water quantity, qualityand ecology are taken into account.This study analyzes the functioning of the ground- and surface water system, what the current bottlenecksare and how these bottlenecks should be tackled in the future. It is also analyzed whether or not theground and surface water regimes will still satisfy during extremely wet or dry periods as a result of climatechange. Possible bottlenecks in the city of Delft are for example floods near buildings, long-during water onthe streets after heavy rainfall and fish death after sewage overflows, but also groundwater levels that aretoo low which can lead to risks for buildings with wooden pile foundations.DHV is executing this study for and together with the Hoogheemraadschap Delfland and the municipality ofDelft. The project is seen as a pilot project. One of the goals is to gain experience with the GGOR in urbanareas. Question that can be asked are:- How strong is the relation between ground and surface water in urban areas?- Will an integrated approach of ground and surface water in urban areas lead to new insights for thetackling of bottlenecks?For the study, an integrated approach for ground water, surface water and the sewage system is used. Differenthydrological models are made in which the in- and output (water balances) should correspond. Forexample the amount of surface water that infiltrates to the ground water according to surface water model(SOBEK) should also be added to the ground water in the ground water model (iMOD), and the other wayaround.The beneath Figure represents the different phases of the project. The first phase of the project mainlyconsisted of the listing and analyzing the available data. Besides that differed surface water models and theground water model were made.22

An important question is: How well do the models reflect reality? To be able to answer this question it isimportant that first all processes of concern are known and that data is available. This proved to be hard,especially for the ground water model. The ‘peilbuisdata’ of the municipality showed that the ground waterin urban areas can fluctuate heavily on short distance, because it is influenced by a lot of factors like localdrainage.The red circle in the Figure indicates the phase of the project we are currently in. Based on the current situationand the optimal ground and surface water regime it will be clear which bottlenecks will be the mostimportant. Also the expected bottlenecks for the year 2015 are presented. In these forecasted bottlenecks,there is attention for climate change. Based on the formulated problems, it is tried to find solutions to tacklethem. The models are used to determine whether or not the measures are effective. In the end, the studyshould lead to a combination of measures that will result in the best possible water system with acceptablecosts for society. This is called the Desired Ground and Surface water Regime. The optimal regime will mostprobably not be reachable because of the high accompanied costs.Finally, based on the desired ground and surface water regime, a ‘peilbesluit’ for the different polders of Delftwill be formulated and decides on by the board of the Hoogheemraadschap Delfland.As explained, the case was focused on our own city,Delft. It was introduced by DHVs real client: the HoogheemraadschapDelfland. We were challenged to comeup with a plan of approach to tackle this urban watermanagement problem.The group was divided in 4 subgroups that were tocompete for the tender. All of the groups started tobrainstorm, have meetings with the client, discussand prepare presentations, only interrupted by a shortlunch in the canteen. A few hours later it was timefor the presentations. Each group had 10 minutes toconvince the client that their approach was clearly ofbetter quality and price than the others and would givethe best solutions for the city of Delft.When the case was concluded we started somethingnew, the DHV speeddate. There were gathered asmany employees as students, and every 5 minutes abell would sound to announce a change of conversationpartner. This way everyone had a chance to get toknow some people from DHV and to get a nice insightin their work and the organistation.An hour later when the speeddate was ended it wastime to finish the day on the Dutch way with a ‘borrel’,with drinks and snacks. This was the moment to evaluatethe day. DHV told about the approach they hadtaken to the original case of the city of Delft, and howit related to our solutions. This was also the time thewinner of the case was announced. The winners got totake home a bag of fair trade chocolate.Returning to Delft the day was concluded with well deservedpizza and drinks in a local restaurant. A nice endof an interesting day!23

“Never a dull moment”By Talitha van HeestThe climate is changing: the sea level is rising, heavyrain storms cause water problems, drought attacks thedikes. The natural surroundings are under pressure:an ever-growing number of people and businesses areproducing more waste water. Are you someone wholeaves this to others?Or do you rise to the occasion? Daily, professionals atthe Hoogheemraadschap van Delfland do their best fora safe living- and working environment, if it storms,rains relentlessly or for weeks on end the weather ishot and dry. Often unseen, yet always essential. Youcan offer your services here!Thalitha (age, 27):“In the team Water en Spatial Development (Water enRuimtelijke Ontwikkeling), a department from the sectorPolicy and Research (Beleid en Onderzoek), I definewater plans for municipalities. What Delfland standsfor is not possible to do by ourselves, other partiesare necessary. An important party is the municipality,which is responsible for the spatial planning. In a waterplan, together with the municipality, we agree on a visionfor the water in urban and rural areas. Followingthis we decide on what measures and which locationsthese could be introduced to, e.g. create more spacefor water, construct an environmentally friendly bankor even separate the waste water from the storm waterin a designated area. The diverse contact with differentdisciplines and the puzzle in searching for thenecessary space to implement these ideas make thiswork interesting!”looking for a more practical way to carry out my work.I had the chance to work at another sector at Delflandas a project manager, the sector Project and Engineering(Project- en Ingenieursbureau). Now I have endresponsibility for five large projects in Westland. Here Ilead a team of about nine specialists. Recently the firsttwo fased projects have been completed. Thanks to myexperience during the start of the spatial developmentfase, I have a better idea of the bigger picture andI know what can happen during the preparation of aproject. My work is varied and challenging; I have animportant responsibility, and because of this, room tomake- and take decisions. There’s no day the same!”Oscar (age, 32):“Working in the world of waste water doesn’t seem thatsexy, but it is! Definitely if you have the role of processmanager and innovation coordinator. The processmanager in the waste water world involves getting municipalitiesand the water board to agree on a vision onthe transportation of waste water. It’s truly interestingto see how, just through looking closely at what you’redoing, you can cleverly think of a number of methodsthat can lead to less costs than when municipalitieswould do the work separately. Next to process managementI coordinate de innovations within Waste WaterTreatment (Zuiveringsbeheer). This involves keepingSabine (age, 28):“I began four years ago at Delfland at Policy and Research(Beleid en Onderzoek).

New MSc programme for Water ManagementBy Jaap de KoningThe faculty of Civil Engineering and Geosciences wantsto restructure its MSc education programmes. The mainobjective of this restructuring is to improve the costbenefitrelation of the education. To fulfil this objectivethe following guidelines are given:• more common courses in each MSc track.• increase the number of compulsory courses.• limit the number of courses of 3 ects.• general out line of the MSc programme: 60ects compulsory courses, 20 ects electivecourse, and 40 ects thesisFor the specialisation of Sanitary Engineering one objectiveis added: revise the existing courses on DrinkingWater Treatment and Wastewater Treatment andreplace those courses with 4 new ones of 5 ects each.The common aspects of both drinking water treatmentand wastewater treatment will be combined in onecourse on Fundamental of Water Treatment. New processesand techniques will be part of two applied coursesand the fourth course deals with the design of watertreatment plants. Next to the water treatment coursesthe courses on sewerage will be revised as well.The new programme has to be implemented at thestart of the academic year 2009-2010.After some internal discussions two alternatives for anew programme for the MSc track has been proposed.Table 1 gives an out line of the two alternatives.The difference between the two alternatives is thedefinition of the compulsory part of the programme dependingon the chosen specialisation within Water Management.In alternative 1 the compulsory part is a fixedlist of courses for each specialisation. The programmeof alternative 2 is more flexible. Next to a number ofcommon compulsory courses a list of so called profilecourses has to be defined. The list of profile courses isa selection of the remaining Water Management coursesand depends on the chair or (sub) specialisation andthesis subject a student prefers.To discuss both alternatives with our students a meetingwas organized by the “Dispuut”. After answering alot of questions and a good discussion regarding thepro’s and con’s of each alternative the conclusion wasdrawn that there was a small preference for the secondalternative. The choice for the alternative two meansthat students have to think about their programmeright at the start of their MSc. For the department itmeans a challenge to guide the students through thisprocess.After the choice was made for the second alternativethe programme was defined in detail, see Table 2.As an example of a profile the profile “Urban Drainage”is given in Table 3.Table 1 Alternatives for a new MSc programme for Water ManagementAlternative 1 Alternative 2Compulsory courses (including common courses) Compulsory common courses 29 ects50 ects Profile courses 21 ectsElective courses 10 ects Elective courses 10 ectsTwo out of four 20 ects Two out of four1 20 ectsThesis 40 ects Thesis 40 ectsTotal 120 ects Total 120 ects26

Company case Witteveen & BosBy Mark Hegnauer (Student) and Floor van den Berg (Witteveen&Bos)On the 12th of February 2009 the ‘Dispuut Water Management’visited Witteveen+Bos to get acquainted withthe company by following a business course. Both thecompany and a student revealed their view on the dayat Witteveen&BosWitteveen+Bos provides consultancy and engineeringservices within the topics: water, infrastructure, construction,environment and economics. Our clients aregovernmental, commercial and industrial, includingvarious types of joint ventures and public private partnerships.We serve them from eight offices in the Netherlandsand seven international offices abroad. For ourmore than 800 employees partnership is the key word:partnership with their clients and with Witteveen+Bos.Personal development is another key issue becauseour work constantly demands new expertise and newresponsibilities. Accountability to our clients is also importantto us. Our employees (at the same time ourshareholders) share this sense of responsibility.The second business course for the Dispuut Watermanagementat Witteveen+Bos since 2007, after which twoformer participants were employed within the SectorWater and several others did their Master project inco-operation with the company, was a major success.The students and the involved employees enjoyed awell-organised day at the head office in Deventer, tryingto compete in the real consultancy and engineeringworld. The objective of the day was on one hand toshow the students the company and the type of workwe do at Witteveen+Bos and on the other hand forWitteveen+Bos to have a glimpse of potential employeesfrom TU Delft.It’s already some time ago since we went to the companycase at Witteveen & Bos, but most of the peoplewho went there will still remember that day. Maybebecause of the nice day we had, but mostly because ofthe very early hour on what we were expected at theentrance of our own faculty. There our trip to Deventerstarted. With two busses we departed at 7:40 am, tojoin the traffic jam on the A13. It seemed the wholecountry was trying to outrun the traffic jam, so therewe stood all together. So with some delay (only half anhour on schedule) we finally arrived at Witteveen&Bos.There the day started with a presentation about thecompany itself, and after that the company case.Witteveen+Bos was happy to welcome 20 students atthe main office. For the business course a multi-facetedtask was developed from Witteveen+Bos projects totempt the students of the different departments WaterManagement join the business course. Two majorcomplex projects concerning the Schiphol Airport area,which are currently developed by Witteveen+Bos, weremerged into one multi-tasking project for the businesscourse. So, a water management system of a futurelogistic business park near Schiphol and the design of awastewater treatment plant at Schiphol Airport had tobe developed by the students, see Figure 1.The case was about Schiphol and the adjustments thathad to be made to the water treatment plant whenSchiphol should grow. Coupled to that, a new area inthe neighborhood of Schiphol would be developed andfor that a water management scheme had to be designed.The goal for the day was to make a design for thenew water treatment plant and to make a design forthe water management scheme for the new developedarea. This was done in little project groups, formed onthe different backgrounds of the students. So in everygroup a water manager, a hydrologist and a sanitaryengineer took place and the day could start. With a laptop,a binder with information and some gigantic mapsof the Schiphol area every group went to its own room.My group went to the basement, and that proved to bethe best location to work in full concentration.From the first minute everybody was working hard.28

First to get familiar with the subject and the Schipholarea, then trying to clarify what had to be done, thenagain trying to understand what had to be done andin the last half hour working on the whole concept anddesign. Between all that hard work there was hardlyany time to have a proper lunch even though Witteveen& Bos provided us with food and drinks. Everyonewas thinking about the deadline, which was already at4 o’clock. At that time the presentations started. Whileone group was still busy finishing their presentation,the first group was already explaining what they haddone and what their results were.After a short presentation with an introduction on thecompany, about the working fields and an explanationof the assignment, the students started with theSchiphol-project in four different consulting groups.For us it was an interesting moment to see how thestudents and some employees of Witteveen+Bos hadthe opportunity to get further acquainted and the winninggroup was announced.After the presentations, the pressure dropped and thefocus went to the drinks afterwards. For that we wentto the Deventer centre were we arrived in a nice andtrendy bar. After planting ourselves at the bar, the beer(and some other drinks) flew richly. There was sometime to talk to people from W+B, but also to peoplewho you never talked to before. After some beers, everyonewas asked to get ready for dinner. When everybodywas seated, the menu arrived and some difficultchoices had to be made. At some tables the menu hadto be translated, but fortunately this was no problem,even after some drinks.During dinner, which was very nice in my opinion, thegreat moment of the day was the announcement ofthe winning project team. Off course every group wasa winner, but there was only one real winner. Fortunatelythat was the group of Marieke, Mark, Jan andmyself. The price was a nice bottle of real Deventersbeer, which tasted very good as I may say.After that ultimate moment of glory the day was ended,but not before Philip had enthusiastically thankedthe people from Witten & Bos. In my opinion it wasa long but very nice day, where pleasure and (some)hard work were combined very good.different groups and the individual students tackle theproblem. Are the tasks strictly distributed based on theexpertise within the group or does the group jointlyreflect on the problem? Is the available informationused wisely and are questions asked actively? Are theexperts within the group properly skilled? In the end,all these different approaches led to different solutionsthat were presented at the end of the day. Ultimately,the winning consulting group was elected based on thisgroup process, the solution itself and the presentation.Hence, an advisor must be able to co-operate (withinit own company and with the client), has to possessthe relevant expertise and has to be able to sell hisproduct. Afterwards we all moved to the city centre ofDeventer for drinks and a cheerful dinner. Here, theIn our opinion, it was a successful and interesting day.We were positively surprised by the knowledge, thecapacity and creativity of the students from the WaterManagement department. Hopefully we have metmany future colleagues. You are always welcome!29

Symposium 2009By Jan TalsmaAs some of you might know, the 2009 symposium committeeis presently swimming in the stormy ocean of“Transboundary Watermanagement”; the danger ofdrown has always been around the corner, but the newdocument, with objectives and intensions of the day,will be ready in the coming week: a save land whichwe invite you to check soon on the Dispuut Watermanagementweb-site.The day’s schedule, which also will be soon available,contains several presentations by prominent speakers,and workshops to make the subject more alive.We will look at several examples of TransboundaryWatermanagment from different perspectives such astechnical, institutional and political, presenting the caseof a river basins in developed countries, like the Rhinein Europe, as well as in developing countries, giving anidea of the broad range of chal-lenges that have to befaced.The goal is to focus on “Past Successes and FutureStrategies”, and to let the audience discuss. by meansof workshops, about the future issues of the presentedriver basins, giving the past evolution of cooperationand examples of successful cases.The Dispuut Watermanagement organizes the yearlysymposium in close cooperation with the UNESCO IHEinstitute for water education. The symposium will beheld in the autumn of this year, the exact date andmore detailed information on the symposium will follow.We are looking forward to this event, and especially toyour comments and suggestions.The Symposium committee 200930
