On-Demand Webinar: HEC-RAS 2D Modeling
Association of State Dam Safety Officials, 2017
With the release of HEC-RAS 5.0 (and newer versions), the Hydrologic Engineering Center (HEC) added the ability to perform two-dimensional (2D) hydrodynamic routing to the HEC-RAS computer model. This webinar will provide an overview of the new HEC-RAS 2D tools and solution processes and the basic capabilities of the HEC-RAS 2D model. The 2D flow modeling can be accomplished by adding 2D flow area element. This is similar to adding a storage area in a 1D unsteady flow model. The flow area is developed by adding a 2D polygon, developing the computational mesh, and linking the 2D flow area either to a 1D model element or directly connecting boundary conditions to the 2D flow area. Each of these steps will be discussed. Guidelines on when to use 2D flow modeling and an example problem of developing a simple computational mesh and running the model will also be covered.
