HEC HMS for HEC RAS Users Part 3 of 4: Using boundary and flow path shape files in HEC RAS models

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 in 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 0:00 Introduction 0:59 Merge shape file features in RAS Mapper 2:18 Create new RAS geometry in RAS Mapper 3:42 Fix mesh errors 7:57 Add boundary conditions to RAS geometry 8:29 Add unsteady flow file 10:10 Add unsteady plan and compute 12:12 View hydrograph and results in RAS Mapper 13:16 Import stream line shape file as profile 14:16 Overview of Part 4 Part 4: Setting up a basic HECHMS model and comparing to HECRAS, manual delin
