Hello all,
I use two superposed models (1D and 2D models) on a given area. By using the mesh of the 2D model I modified the geometry file of the 1D model so that both models have the same bathymetry on this area.
The free surface levels computed with Mascaret are used as free surface downstream boundary conditions for the 2D model and the discharges computed with Mascaret are used as upstream boundary conditions for the 2D model.
The problem is that the water depth computed with Mascaret at a given cross section (Z(10)-ZREF(10)) is not the same as the mean water depth computed with Telemac on the same cross section (mean of H%R on the cross section) ... The difference is almost constant and about 3 meters
Do you know where this difference originate from ? Is there some parameter to set ?
More, even though I'm not in the Mascaret forum do you know how is computed the ZREF variable in Mascaret ?
Thanks for your answers
