WebSince I've been thinking of using the Muskingum-Cunge method of routing in HEC-HMS, I can't understand how to decide the initial inflow type. There are two options: Discharge = inflow (steady state condition where initial inflow = initial outflow) Specified dischage (where you provide an initial inflow) Since, I don't have a gauge upstream, I ...
WebFirst the runoff is obtained from the precipitation data with HEC-HMS model. The obtained runoff is then simulated in HEC-RAS. The output of HEC-RAS is then exported to HEC-GeoRAS for flood plain mapping.
