Avoid Costly Mistakes Using HEC-RAS: Geometric Misrepresentations & Understanding Computations

This two-part course is the first half of our HEC-RAS Webinar Series. The second half is Bridge Modeling Using HEC-RAS: Building the Model & Modeling Guidelines.

HEC-RAS is a rather complicated 1-D and 2-D hydraulics program that can be easily put together but also easily—and unknowingly—misused.

Join Stormwater University for this educational, two-part webinar as prolific speaker Dr. David T. Williams (a former HEC staffer and expert HEC-RAS user) presents examples of subtle misuses of HEC-RAS that could have potentially significant effects on a project’s hydraulic results. Programming Note: Since most HEC-RAS models are still performed in 1-D, this course will concentrate on only 1-D applications.

Part I will discuss geometric misrepresentations and misconceptions about how HEC-RAS performs its 1-D computations on the geometric layout. Part II will detail how HEC-RAS performs its 1-D computations and how to properly configure HEC-RAS to simulate real-world phenomena.

Course material will be based upon Dr. Williams’ review of submitted models, his discussions with experienced users, his blogs on hydraulic modeling topics, and his HEC-RAS Steady and Unsteady course lecture notes. Each example will be presented as if a reviewer was examining a submitted HEC-RAS model.

Part I Learning Objectives:

Explain how to avoid the subtle mistakes presented
Understand the thought process going from existing to project conditions
Use graphics for reviewing HEC-RAS models
Recognize the symptoms of a faulty HEC-RAS model
Determine what is and is not “allowed” in HEC-RAS modeling

Part II Learning Objectives:

Explain how HEC-RAS does its computations for various hydraulic conditions
Determine what options to invoke for each type of hydraulic phenomena
Explain the relative magnitude of error that is generated going from one option to another
Understand the proper sequence for reviewing HEC-RAS models
Explain how project limits, model limits, and study limits are different
