1. I am having the same error with SI units. When I input a sediment load series of 1 tonne/day, Mass input for the relevant cross section shows a mass series of 2.43 ton. Has anyone found a solution??
2. I am modelling a river for sediment transport and the boundary conditions I use is Sediment load series.
Other than the upstream boundaries, I have defined lateral sediment flow series also. But when I run the model and check the results what I saw was HEC-RAS didn’t take those lateral sediment flows to calculations.
3.Is it essential to define downstream boundary condition for sediment also. My model runs without downstream sediment boundary conditions. No need to worry about that, right???
