<strong>hydrology</strong> <strong>and</strong> <strong>hydraulic</strong> <strong>modell<strong>in</strong>g</strong><br />
Respected thought leaders with<strong>in</strong> our <strong>in</strong>dustry, we specialise <strong>in</strong> fluvial, coastal <strong>and</strong><br />
estuarial <strong>hydrology</strong> <strong>and</strong> <strong>hydraulic</strong> <strong>modell<strong>in</strong>g</strong>.<br />
Our versatility, knowledge <strong>and</strong> experience means we are frequently asked to provide <strong>in</strong>novative,<br />
susta<strong>in</strong>able <strong>and</strong> practical flood risk management solutions for often complex water related<br />
projects <strong>in</strong> <strong>the</strong> <strong>UK</strong>, Europe, <strong>and</strong> worldwide.<br />
Involved <strong>in</strong> help<strong>in</strong>g communities experienc<strong>in</strong>g <strong>the</strong> effects of extreme flood<strong>in</strong>g our scientists<br />
<strong>and</strong> eng<strong>in</strong>eers carry out <strong>hydraulic</strong> <strong>modell<strong>in</strong>g</strong>, flood forecast<strong>in</strong>g, GIS-based mapp<strong>in</strong>g <strong>and</strong> provide<br />
risk management expertise. Tasks <strong>in</strong>clude establish<strong>in</strong>g basel<strong>in</strong>e data, analys<strong>in</strong>g flood defence<br />
performance, <strong>and</strong> develop<strong>in</strong>g <strong>and</strong> apply<strong>in</strong>g <strong>in</strong>novative <strong>modell<strong>in</strong>g</strong> <strong>and</strong> data management tools.<br />
Our hydrological <strong>and</strong> <strong>hydraulic</strong> expertise is used to:<br />
l Help with flood event decision mak<strong>in</strong>g, <strong>in</strong>clud<strong>in</strong>g plann<strong>in</strong>g for or prevent<strong>in</strong>g <strong>the</strong> evacuation<br />
of homes dur<strong>in</strong>g a flood<br />
l Obta<strong>in</strong> consents or approvals, e.g. under <strong>the</strong> Water Framework Directive<br />
l Design improvements to ports, <strong>in</strong>clud<strong>in</strong>g dredg<strong>in</strong>g <strong>and</strong> wave disturbance assessments<br />
l Help authorities make decisions surround<strong>in</strong>g development control, urban dra<strong>in</strong>age, flood<br />
warn<strong>in</strong>g <strong>and</strong> management of flood <strong>and</strong> coastal defences

We work with <strong>the</strong> Environment Agency on hydrological projects commissioned through <strong>the</strong> NEECA<br />
<strong>and</strong> SFRM frameworks, <strong>and</strong> with local authorities <strong>in</strong>clud<strong>in</strong>g Moray Council as part of <strong>the</strong> Moray Flood<br />
Alleviation partnership. Many of our senior professionals are represented on national <strong>and</strong> <strong>in</strong>ternational<br />
committees, such as CIWEM’S Rivers <strong>and</strong> Coastal Group, which is proactively <strong>in</strong>volved <strong>in</strong> both national<br />
<strong>and</strong> <strong>in</strong>ternational knowledge build<strong>in</strong>g <strong>and</strong> shar<strong>in</strong>g.<br />
Fluvial <strong>hydrology</strong><br />
We assess river flows, flood risk <strong>and</strong> flood alleviation options us<strong>in</strong>g validated hydrological <strong>in</strong>formation<br />
from previous studies, gauge data <strong>and</strong> historical <strong>in</strong>formation. We are regularly commissioned to<br />
undertake high level reviews of hydrological analyses.<br />
Coastal <strong>hydrology</strong><br />
We study <strong>the</strong> <strong>hydraulic</strong>s of a coastal region to underst<strong>and</strong> <strong>the</strong> movement of tides <strong>and</strong> waves <strong>and</strong><br />
apply hydrodynamic models to simulate <strong>the</strong> direction <strong>and</strong> magnitude of tidal currents, waves <strong>and</strong> <strong>the</strong>ir<br />
<strong>in</strong>teractions. We exam<strong>in</strong>e <strong>the</strong> effects of storm surges <strong>and</strong> climate change on water levels <strong>and</strong> waves,<br />
<strong>and</strong> <strong>the</strong> changes to flow fields as a result of offshore developments.<br />
Hydraulic <strong>modell<strong>in</strong>g</strong><br />
We undertake <strong>hydraulic</strong> <strong>modell<strong>in</strong>g</strong> for rivers, coasts <strong>and</strong> dra<strong>in</strong>age systems us<strong>in</strong>g one, two <strong>and</strong> three<br />
dimensional models. These results help us develop effective flood <strong>and</strong> coastal risk management<br />
solutions, plan coastal developments, <strong>and</strong> assess environmental impacts such as water quality <strong>and</strong><br />
sediment transport. Our <strong>in</strong>-house GIS capability supports <strong>the</strong>se activities.<br />
Software<br />
We apply <strong>and</strong> develop numerical <strong>modell<strong>in</strong>g</strong> software to aid design <strong>and</strong> assessment. Software packages<br />
used <strong>in</strong>clude:<br />
l ISIS (HR Wall<strong>in</strong>gford/Halcrow) – 1D river <strong>modell<strong>in</strong>g</strong> of open channel systems<br />
l TUFLOW (WBM) – 2D flood simulation model, can be l<strong>in</strong>ked to ISIS to create <strong>in</strong>tegrated<br />
1D/2D models;<br />
l Infoworks (Wall<strong>in</strong>gford Software) – a suite of models for river systems, urban dra<strong>in</strong>age<br />
networks, <strong>and</strong> water supply <strong>and</strong> distribution<br />
l MIKE21 (Danish Hydraulics Institute) – a suite of 2D models to simulate wave dynamics,<br />
tidal flows <strong>and</strong> sediment transport<br />
l SWAN (Delft Hydraulics) – 1D <strong>and</strong> 2D simulation of wave propagation<br />
l Amazon (Manchester Metropolitan University/<strong>Royal</strong> <strong>Haskon<strong>in</strong>g</strong>) – wave overtopp<strong>in</strong>g model<br />
