Learn how to add terrain, shapefiles and web imagery within HEC-RAS directly.Participants who wish to attend this webinar must be well-versed in using previous software versions of unsteady HEC-RAS and GIS software. The webinar discusses briefly the use of RAS Mapper in the development of the 2D model, preparing and importing composite surfaces to include “proposed†conditions in the modeling, with an emphasis on the coupling of the 1D and 2D portions of the model in RAS 5.0. This webinar focuses on a more in-depth look at the use of HEC-RAS 5.0 1D/2D coupling ability. Visual depictions of the floodwave assist with presentation to the public, clients and for reports and submittals. The 2D component allows the modeler to fully account for overbank storage volume plus the diversion and return of the overbank flow to the channel. Visualization of the hydraulic results is extremely useful in estimating flooding extents, determining key causes of flooding and developing mitigation strategies. This ability allows the modeler to fully capture the nature of the runoff event flow patterns and depths.

There is also the ability to apply precipitation to the 2D surface, as well as external hydrographs and other boundary conditions to the 2D surface. HEC-RAS V5.0 has the ability to model runoff in a 2D environment coupled with traditional 1D modeling. This webinar is part of a 3-part series on HEC-RAS.
