I have some idea to want to try my 2D-flood modle.
That is set one point in my Area anywhere(Not on the boundary),
The point will have [discharge for flow hydrograph], just like a Source in my area.
but,I want to know “Can HEC-RAS for current version do it ?”
There isn’t a easy way to do this in RAS V5.0.3. A work around is to split the 2D flowarea into 2 or more flow areas and put a “1D storage area” in the area you want to apply hydrograph. Delineate 2D flow areas around the storage area and then connect the storage area to the 2D flow areas with storage area connectors. Now you can insert a hydrograph into the storage area and it can spill over the connectors into the 2D flow areas
