Spring 2025 Online Class - HEC RAS 2D

This intensive 6-week workshop will instruct students on the use of HEC-RAS for two-dimensional hydraulic modeling. The course will include an overview of 2-D flow theory, RAS Mapper, and the differences between 1-D and 2-D modeling. The use of the model is taught through hands-on exercises and real-world project examples. Students should have an existing working knowledge of HEC-RAS. 

Topics

The seminar includes lectures on:

·         2D flow theory

·         RAS Mapper

·         2D model troubleshooting and calibration  

·         Two-dimensional flow analysis using the full Shallow Water Equations or Diffusion Wave equations in 2D.

·         Ability to perform a combination of 1D and 2D flow analysis in the same model.

·         The use of unstructured or structured computational meshes for the 2D flow areas.

·         2D Bridges

·         Spatial Precipitation (i.e. Rain on Grid)

·         Turbulence and Wind

Workshops

Workshops focus on giving students hands on experience with building and pre-processing the computational mesh, performing offline and inline 2D projects, and using the built-in feature RAS Mapper to spatially analyze results. The 5 workshops included in this class are:

·         Creating a 2D Model

·         2D Bridge Modeling

·         River Restoration

·         Dam Breach Analysis

·         Levee Breach Analysis.

Who Should Attend

Consulting engineers, water resource planners, engineers employed by local, state, or federal government agencies. Participants should have some experience in floodplain hydrology and hydraulics, and sound experience in HEC-RAS steady and unsteady flow computer modeling. They should also be able to follow simple computer instructions.
