This video builds on our "prequel" video covering folder setup, projection files, terrain surfaces, and RAS Mapper basics:    • HECRAS Basics Part 1 of 8: Download ...  .

This video explains how to create a 1D geometry file within RAS Mapper. This exercise covers a very basic model setup attend an open, online, or inhouse course to unlock the full potential of HECRAS with junctions, structures, and other more complex model geometries. If you need help with your own project, we can customise a solution for you; please send an inquiry using http://www.surfacewater.biz/contact/.

This video steps through the process of delineating channels and cross sections from scratch within RAS Mapper. An alternative method that we'll cover in an upcoming video is to import the features from shape files.
