HEC-RAS Basics Part 1 of 8: Download and install HEC-RAS with tips and tricks for getting started

In this "prequel" video, we step through the process of starting a HEC-RAS model from scratch, including downloading and installing HEC-RAS, accessing free terrain data and projection files, establishing a standard file structure, and setting up RAS Mapper.
