Modified Puls Routing, also known as storage routing or level-pool routing, is a commonly used reach (channel) routing method in HEC-HMS. Modified Puls Routing is based on continuity equation. In…
After a watershed has been delineated using HEC-HMS GIS tools, the subbasins and reaches can be further refined using HEC-HMS merge and split functions. Five subbasins and two reaches were…
The new HEC-HMS published around 2020 has some useful GIS tools to delineate a watershed using terrain data. Unlike HEC-GeoHMS, these standalone GIS commands are an integral part of HEC-HMS…
