I have modeled storage area, inline structure and downstream river reach in HEC-RAS for dam break analysis. After giving the boundary conditions, the model was run. But it is showing some stability problem. Discharges have negative values. I am not able to run the model because of stability problem. Can anyone suggest me what could be the problem?
I also have some stability problems with a dam break case. I also am a bit confused about the dam break hydrograph that is produced. Can someone help? Thanks in advance
