HEC-HMS for HEC-RAS Users Part 2 of 4: Catchment/watershed and flow path delineation in HEC-HMS

To mark yesterday’s release of the highly anticipated HEC-HMS Version 4.9, we’ve put together some video tutorials showing how easy it is to use HEC-HMS to delineate catchments/watersheds and flow paths, which can be very useful in HEC-RAS models.
