I tried to simulate the transport of a sand dune in a rectangular channel by the equation of Hansen England through HECRAS I did all the steps, but I can not find how to bring the geomtrique of sand dune ; i find in the geomtrique data (fixed sediment elevation) so I introduie geometry of the dune when I made the simulation I can not find the results; the dune remained stable by time no transport . I think there is a mistake since I use fixed sediment are there any other steps that the sediment for mobile knowing that I introduced sediment data

Our warehouse is huge and there are numerous doors for truck and rail so that the transportation is easy and fast. Rail to truck and vice versa and rail to container etc. provide fastness in our work.
