HEC-HMS for HEC-RAS Users Part 4 of 4: Setting up a basic HEC-HMS model and comparing to HEC-RAS

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 for setting up HEC-RAS models. Part 1: Introductory comparison of rainfall runoff routing (HMS) and rain-on-grid (RAS) Part 2: Delineating watershed boundaries and flow paths in HEC-HMS Part 3: Using boundary and flow path shape files in HEC-RAS rain-on-grid models Part 4: Setting up a basic HEC-HMS model and comparing to HEC-RAS, manual delineations in RAS Mapper using GIS commands 0:00 Introduction 0:20 Merge and split HEC-HMS elements 0:48 Create new meteorological model 2:19 Create new control specification 3:16 Enter basin losses, transform, and baseflow 5:21 Enter reach properties 7:05 Create new simulation run 7:35 Export results 9:34 Add basins ma
