Culvert Modeling Using HEC-RAS

COURSE DESCRIPTION

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. The most common hydraulic structures modeled are related to culvert modeling.

Join Forester University for this live, educational, two-part webinar as prolific speaker Dr. David T. Williams (who has taught HEC-RAS and bridge and culvert hydraulics to the Federal Highway Administration as well as state and local departments of transportation) presents examples of common geometric mistakes and misunderstandings of culvert parameters using HEC-RAS that could have potentially significant effects on a culvert 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 culvert applications.

Part I will discuss common 1-D geometric misrepresentations, the proper placement of cross sections within an HEC-RAS model, and initial coefficients to use to properly simulate the hydraulic effects of a culvert. Part II will detail how some of the input parameters should be refined, where within the 1-D model they should be placed, and a step-by-step creation of an HEC-RAS culvert model with a real culvert.

Course material will be based upon Dr. Williams’ review of submitted models, his discussions with experienced users, his blogs on hydraulic and culvert modeling topics, and his HEC-RAS Steady and Unsteady course lecture notes.
