Laurent,<br><br>Dambreak analysis is very complex, requiring a lot of in-channel cross-section or bathymetric data and over-bank DEM data, as well as the use of an unsteady hydraulic flow model such as the U.S. Army Corps of Engineers, HEC-RAS model, which has this capability.<br>
<br>However, there are simplified techniques that can approximate detailed analyses, such as:<br><br><a href="http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CCUQFjAA&url=http%3A%2F%2Fwww.hsdl.org%2F%3Fview%26did%3D8227&ei=rV-JUJGSGYjO0QHEw4BI&usg=AFQjCNHIGNVpLU5UZZ9ZuTfhi-tySFIs8w">http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CCUQFjAA&url=http%3A%2F%2Fwww.hsdl.org%2F%3Fview%26did%3D8227&ei=rV-JUJGSGYjO0QHEw4BI&usg=AFQjCNHIGNVpLU5UZZ9ZuTfhi-tySFIs8w</a><br>

<br>
I have to simulate an artificial dam failure & mapping of flood risk<br>
downstream. I have already generate watershed file thanks to r.watershed.<br>
<br>
Now i want to mapping and calculate flood risk downstream (water level /<br>
volume /cubature) from a few available informations like charge,flow,etc.<br>
<br>
Could you throw light for me please? If you know other tools and algorithms<br>
that can help me in my study, don't hesitate.<br>
<br>
Thank you in advance.<br>
<br>
With kind regards.<br>
