hello!
in my case, the downstream boundary water level is 59.64m, and the lowest elevation of the river bed is 56.4m which is lower than the elevation of water surface, but the result shows that the given water surface is below bed and fail in calculation. This is the question confusing me. hope for your help~
best regards

Hello,
The downstream end of the calculation grid may not be set correctly.
Check your grid.
