Can anybody give me any suggestion about how to model a levee breach in TELEMAC2D. Is it possible to alter the topography values at the nodes and elemennts of the mesh during the model run. I meant, can we lower the elevation of some portion of the levee after the water reaches the bankfull level?

Hello,

Yes, you can change the bottom topography as you like, the depth is preserved, it will be just the free surface that will be changed, and water will flow according to this new free surface.

You can also have a look at what has been implemented for breaches in version 6.2, which is described in the enclosed document (found under the topic "feature log").

With best regards,
