Tutorial on using HEC-GeoRAS with ArcGIS 9.3

This tutorial, from Purdue University, "is designed to expose users to basic functions in HEC-GeoRAS for pre- and/or post-processing of GIS data and HEC-RAS results for flood inundation mapping using ArcGIS." After outlining computer and data requirements, the tutorial outlines "Setting up Analysis Environment for HEC-GeoRAS," "Creating RAS Layers," creating river centerlines and banks, flowpaths, bridges and culverts, ineffective flow areas, and obstructions, all with images and screenshots to supplement. It also outlines how to export the data.
