Hi, I am analyzing the flow as a result of a failure of a sedimentation pond in mike 21 HD and I would like to simulate the inflow of waste from the TSF into the river. And here is my question, how do I set the water level in the river? I would like my analysis to take into account the water level that is in "normal" conditions and after the wave from the TSF has arrived. I do not have access to mike 11, so the entire model must be in 2D. Thank you in advance and best regards, Krzysztof
