HEC-RAS 2D

This event qualifies for 21 PDHs

This is an interactive seminar focused on the practical use and advantages of two-dimensional flow capabilities in HEC-RAS, with emphasis on applications for the dam safety industry. The course will maintain a balance between lecture-style presentations on model theory and hands-on workshop sessions for practical examples. Topics will include applications and benefits of HEC-RAS 2D modeling; RAS Mapper and terrain preparation; executing 2D models including dam, levee, and breach simulations; viewing and analyzing results with RAS Mapper; troubleshooting and model review. The course will also cover new features released with recent updates to HEC-RAS , such as spatial precipitation and infiltration; 2D bridge hydraulics; improvements to RAS Mapper; and more. The course will utilize the most recent version of the HEC-RAS software available at that time. Attendees are advised to have recent HEC-RAS 1D unsteady experience and working knowledge of the HEC-RAS user interface. Prior completion of ASDSO’s HEC-RAS Course is a recommended prerequisite.

Learning objectives attendees will receive from this course:

Understand when and where to use HEC-RAS 2D.
Develop necessary input/terrain data for HEC-RAS 2D.
Create and run a HEC-RAS 2D model.
Troubleshoot and review a HEC-RAS 2D model.
Utilize HEC-RAS 2D for various dam safety applications.
