Best way to model erosion or deposit

[Antoine_Bard]

Hello everyone,

I am looking for a way to model sediment deposit in my 1D or 1D/2D model. I don’t necessary need to use the sediment tool, unless I have too (but so far I ve never tried it). I just want to model the consequences on the water elevation of a deposit of 50 cm in the whole channel or some long portion of it.
I have taken a look at the Channel modification tool but it doesn’t seem to be the right tool to do it, as I just want to fill the bottom of each cross section and nothing else.

Thank you for your answer.

Hi Antoine,

It sounds like you want to use the Fixed Sediment Elevations under Tools in the Geometric Data Editor. You can apply sediment to one or multiple cross sections, either at individual elevations or at a slope across the reach.

Hi Jake,

This works just fine, thanks a lot.
