HEC-RAS Webinar Series

Description

Join us for this educational, two-part webinar series as prolific speaker Dr. David T. Williams 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.

Credits: 4.0 PDH / 0.4 CEU  

Part I will discuss 1-D geometric misrepresentations and the proper placement of cross sections within an HEC-RAS model to properly simulate the hydraulic effects of a bridge. Part II will detail how some of the input parameters should be determined and where within the 1-D model they should be placed. Course material will be based upon Dr. Williams’ review of submitted models, his discussions with experienced users, his blogs on hydraulic and bridge modeling topics, and his HEC-RAS Steady and Unsteady course lecture notes.
