Terrain Modification in HEC-RAS Part 1: Bathymetry

In this video, we add bathymetry to a river channel using a 1D geometry created in RAS Mapper. In Part 2 we'll cover removing no-data areas, and in Part 3 we'll cover the addition of dams, levees, buildings, detention basins, etc. Part 4 covers the replacement of no data values.

Note: the methods shown in these video are outdated for all applications except adding bathymetry. Use the new terrain modification tools in HEC-RAS Version 6 for buildings, dams, levees, etc. Updated instructions for linear features are shown here:    • What's new in HEC-RAS 6.0 Part 4: Ter...   and instructions for polygon features are shown here:    • What's new in HEC-RAS 6.0 Part 5: Pol...  .
