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

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. 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 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 HEC-HMS model and comparing to HEC-RAS, manual delin
