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

To mark yesterdays release of the highly anticipated HECHMS Version 4. 9, weve put together some video tutorials showing how easy it is to use HECHMS to delineate catchments, watersheds and flow paths, which can be very useful for setting up HECRAS models. Part 1: Introductory comparison of rainfall runoff routing (HMS) and rainongrid (RAS) Part 2: Delineating watershed boundaries and flow paths in HECHMS Part 3: Using boundary and flow path shape files in HECRAS rainongrid models Part 4: Setting up a basic HECHMS model and comparing to HECRAS, manual delineations in RAS Mapper using GIS commands 0:00 Introduction 0:20 Merge and split HECHMS 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
