open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,

I'm simulating a wave in a 10m channel (0.8m wide) with Surface level and Discharge time series as inflow boundary condition and free flow (4 4 4) at the outflow boundary. When I compare the input time series with TELEMAC simulated results at the inflow boundary, the water surface seems to drop in simulation even though its not the case in the input signal. Below attached is the comparison at the inflow boundary. This drop in surface elevation increases close to the outlet. The simulation files are attached for reference. Any help would be great. Many thanks!
