Creating your mesh in RAS 2D

Your computational mesh is what will allow you to do 2D modeling in HEC-RAS. Think of a mesh as a net that you drape over your terrain. The continuous properties of the “infinite” terrain are then discretized onto the mesh so that computations can be made over a finite domain. Here in the geometry editor, […]

Quickly Edit Reach Lines in the Geometry Editor

Editing the positioning of your geometry in HEC-RAS can sometimes be a pain, especially with large systems. This tip will show you how to quickly (and easily!) remove sections of a reach. If you import reach stream lines through ArcGIS, or a similar program, your schematic may look similar to the figure below. In this […]
