HEC-RAS 1-D Modeling for Stream Restoration with New NFIP Content

EPP 234 -- HEC-RAS 1-D -- Steady Open Channel Flow Modeling Emphasizing Stream Restoration Applications.
Instructor: Gary Wolff, Senior Hydraulic Engineer, Otak

Course Summary: This short course will provide a thorough introduction to the capabilities of the well-known U.S. Army Corps of Engineers Hydrologic Engineering Center - River Analysis System (HEC-RAS). This entry-level to intermediate-level course is intended for river restoration practitioners with backgrounds in geoscience, the life sciences or engineering with an interest in learning to use HEC-RAS in the context of restoring rivers or needs to make reliable interpretations of the outputs of HEC-RAS models built and run by colleagues and other river restoration stakeholders. Participants should have a basic understanding of the physics of open channel flow and experience using a Windows PC.
The course will provide an overview of the HEC-RAS model with hands-on experience in using the software for modeling a variety of situations commonly encountered when restoring rivers. It will include in-depth instruction on: fundamentals of open channel flow; using HEC-RAS to model stream flows and drainage networks; and, modeling river crossings (bridges and culverts) to ensure they meet relevant fluvial performance standards and are passable by aquatic organisms. It will also deal with hydraulic modeling of natural streams and streams with added habitat features (e.g. large wood, boulders), and it will touch on using one and two-dimensional modeling in the context of habitat suitability evaluation and FEMA-CLOMA permitting.

The course will take place from 8am to 5 pm each day (Nov 1-4, 2022).

Students must bring their own laptop to download the public domain HEC-RAS software. Microsoft Excel (or the ability to import/export into/from MS Excel) is also necessary for the course.
