Initial Situ<strong>at</strong>ion Slope/ Embankment Stabilis<strong>at</strong>ion<br />
To maintain a secure use <strong>of</strong> <strong>the</strong> street <strong>the</strong> occurring rain and snow w<strong>at</strong>er is drained <strong>of</strong>f <strong>the</strong><br />
street through a small l<strong>at</strong>eral inclin<strong>at</strong>ion into parallel running longitudinal draining facilities on<br />
<strong>the</strong> side, most <strong>of</strong>ten draining troughs or spherical shell channels.<br />
Coming from st<strong>at</strong>utory regul<strong>at</strong>ions <strong>the</strong> w<strong>at</strong>er has to be brought back again into <strong>the</strong> n<strong>at</strong>ural<br />
circle <strong>of</strong> <strong>the</strong> w<strong>at</strong>er. Mostly this happens immedi<strong>at</strong>ely where possible through l<strong>at</strong>erally passing<br />
<strong>the</strong> w<strong>at</strong>er out into <strong>the</strong> surrounding terrain. In <strong>the</strong> surrounding terrain <strong>the</strong> w<strong>at</strong>er should ooze<br />
away.<br />
On account <strong>of</strong> <strong>the</strong> global clim<strong>at</strong>e changes and <strong>the</strong> increase <strong>of</strong> extreme we<strong>at</strong>her caprioles<br />
conditioned <strong>the</strong>reby, <strong>the</strong> frequency and amplitude <strong>of</strong> extreme rain and snow fall incidents<br />
has strongly increased in wide parts <strong>of</strong> Europe during <strong>the</strong> past years. Also <strong>the</strong> street draining<br />
facilities are immedi<strong>at</strong>ely affected <strong>of</strong> this. They can not ooze away <strong>the</strong> big quantities <strong>of</strong> rain<br />
and snow w<strong>at</strong>er in <strong>the</strong> surrounding terrain without causing damages as initially planed.<br />
In <strong>the</strong> here mentioned project „Traunufer/ Wels“ <strong>the</strong> draining <strong>of</strong>f <strong>the</strong> w<strong>at</strong>er from <strong>the</strong> street into<br />
<strong>the</strong> surrounding wooded area caused an always deeper eroding trench because <strong>of</strong> <strong>the</strong> big<br />
quantity <strong>of</strong> <strong>the</strong> surface w<strong>at</strong>er.<br />
The terrain steeply sloping from <strong>the</strong> country road to <strong>the</strong> river Traun was eroded on a length <strong>of</strong><br />
117m up to a depth <strong>of</strong> 1.50 m. Half <strong>of</strong> <strong>the</strong> width <strong>of</strong> a forest road crossing this section was<br />
swept away by <strong>the</strong> erosion. In <strong>the</strong> sequel <strong>the</strong> forest road was unusable for <strong>the</strong> managing <strong>of</strong><br />
<strong>the</strong> forest.<br />
In this area near Wels <strong>the</strong> river Traun is used for <strong>the</strong> energy production and <strong>the</strong>refore it is<br />
dammed up to a river power st<strong>at</strong>ion. Through <strong>the</strong> erosion <strong>of</strong> <strong>the</strong> embankment <strong>the</strong> dammed<br />
w<strong>at</strong>er <strong>of</strong>ten became muddy. Because <strong>of</strong> <strong>the</strong> washed in fine sediments a damage <strong>of</strong> <strong>the</strong><br />
power st<strong>at</strong>ion equipment could not longer be excluded.<br />
Central setting <strong>of</strong> task for <strong>the</strong> reconstructing work was to elimin<strong>at</strong>e <strong>the</strong> damage in form <strong>of</strong> a<br />
very deep erosion trench, to make <strong>the</strong> forest road usable again and to construct a stable<br />
channel for <strong>the</strong> future drainage <strong>of</strong> <strong>the</strong> street w<strong>at</strong>er.<br />
The first design intended to build a coursed rock fill out <strong>of</strong> coarse river stones which would<br />
have had a single weight <strong>of</strong> approx. 1.000 up to 2.000 kg per piece.<br />
The coursed rock fill should start <strong>at</strong> <strong>the</strong> bank <strong>of</strong> <strong>the</strong> river Traun and should <strong>at</strong> least be built up<br />
to <strong>the</strong> level <strong>of</strong> <strong>the</strong> forest road. For <strong>the</strong> section above <strong>the</strong> forest road <strong>the</strong> construction <strong>of</strong> a<br />
draining pipe was planed which should have drained <strong>of</strong>f <strong>the</strong> street w<strong>at</strong>er into <strong>the</strong> coursed<br />
rock fill.<br />
This variant for <strong>the</strong> project was too expensive and too troublesome because <strong>of</strong> some<br />
problems with <strong>the</strong> basement for <strong>the</strong> coursed rock filling, <strong>the</strong> troublesome and expensive<br />
transport<strong>at</strong>ion <strong>of</strong> <strong>the</strong> stones to <strong>the</strong> constructing site (entry way was only possible on <strong>the</strong> little<br />
bearing forest road) and <strong>the</strong> technically very troublesome install<strong>at</strong>ion <strong>of</strong> <strong>the</strong> piping line in <strong>the</strong><br />
steep slope.<br />

Additionally <strong>the</strong> whole stabilis<strong>at</strong>ion work should be done without severe affects on and<br />
constant injuries to <strong>the</strong> landscape because <strong>the</strong> terrain is very good seen and is used as close<br />
recre<strong>at</strong>ion area.<br />
The mentioned situ<strong>at</strong>ion induced <strong>the</strong> constructing company Felbermayr to give a special<br />
constructing suggestion using <strong>the</strong> <strong>Krismer</strong>® System.<br />
Constructing suggestion with <strong>Krismer</strong>® System<br />
- Extension <strong>of</strong> <strong>the</strong> existing erosion trench to a drainage trench, width <strong>at</strong> least 0.60 m up to<br />
1.20m, depth <strong>at</strong> least 1.0 m to 1.50 m;<br />
- Filling up <strong>the</strong> drainage trench with easy to deliver stone m<strong>at</strong>erial in stone sizes up to maximal<br />
32 mm to 60 mm;<br />
- Stabilising <strong>of</strong> <strong>the</strong> draining body with three-dimensional steel l<strong>at</strong>tice m<strong>at</strong>s, anchored with <strong>the</strong><br />
underground with earth nails; forming a terrain trough (opening width approx. 6 m) and<br />
- stabilising <strong>of</strong> <strong>the</strong> whole trough with <strong>Krismer</strong>® System as additional possible draining facility for<br />
<strong>the</strong> street w<strong>at</strong>er in <strong>the</strong> case <strong>of</strong> a flood.<br />
- Applying humus and greening <strong>of</strong> all parts which are not permanently overflowed with w<strong>at</strong>er<br />
guaranties a perfect reintegr<strong>at</strong>ion <strong>of</strong> <strong>the</strong> construction work into <strong>the</strong> surrounding n<strong>at</strong>ural river<br />
landscape.<br />
The construction method drainage-and channel-constructing with “<strong>Krismer</strong>® System” as<br />
presented was proved to meet all <strong>the</strong>se requirements <strong>of</strong> <strong>the</strong> stabiliz<strong>at</strong>ion in a perfect way,<br />
<strong>the</strong>refore this method was executed.<br />

doing this <strong>the</strong> growth <strong>of</strong> <strong>the</strong> plants should be acceler<strong>at</strong>ed and a fast and thick growing <strong>of</strong> <strong>the</strong><br />

Embankment<br />
Result Slope/<br />
In <strong>the</strong> course <strong>of</strong> <strong>the</strong> channel lining on <strong>the</strong> bank <strong>of</strong> <strong>the</strong> river Traun <strong>the</strong> <strong>Krismer</strong>® System was<br />
carried out to stabilise <strong>the</strong> terrain.<br />
As results <strong>of</strong> this construction project <strong>the</strong> following provable effects could be achieved:<br />
• long-lasting protection <strong>of</strong> <strong>the</strong> bank surface against all types <strong>of</strong> erosion<br />
• <strong>the</strong> deep reaching compound effect and <strong>the</strong> stable construction <strong>of</strong> <strong>the</strong> three-dimensional<br />
steel l<strong>at</strong>tice panels oppose optimally <strong>the</strong> tractive force <strong>of</strong> <strong>the</strong> w<strong>at</strong>er<br />
• surface securing stays w<strong>at</strong>er permeable and prevents an excessive build up <strong>of</strong> <strong>the</strong> flow<br />
pressure<br />
• <strong>the</strong> stone filling <strong>of</strong> <strong>the</strong> drainage trench decisively reduces <strong>the</strong> r<strong>at</strong>e <strong>of</strong> flow<br />
• except <strong>the</strong> installed system nails no excessive basements were necessary<br />
• <strong>the</strong> construction is insensitive for consolid<strong>at</strong>ion <strong>of</strong> <strong>the</strong> subsoil (= flexible construction)<br />
• all system components including <strong>the</strong> filling m<strong>at</strong>erial can be transported to <strong>the</strong> constructing<br />
site in <strong>the</strong> steep slope very easily<br />
• <strong>the</strong> stabilised top soil layer forms <strong>the</strong> basis for a long-lasting growing <strong>of</strong> plants<br />
• Using <strong>the</strong> <strong>Krismer</strong>® System enabled us to optimally stabilise <strong>the</strong> channel in a steep slope<br />
with an inclin<strong>at</strong>ion <strong>of</strong> 40°. Using this ecologically desirable, plant-able construction<br />
valuable n<strong>at</strong>ural landscape could be saved or a once devast<strong>at</strong>ed surface could be recultiv<strong>at</strong>ed<br />
again.<br />
