The University of Virginia invites you to attend a hands-on workshop focused on applications of the hydraulic modeling software, HEC-RAS. By working through seven different applications throughout the day, participants will become familiar with relevant model tools as well as develop modeling skills applicable to a range of hydraulic analyses that can impact transportation design. Workshop applications include: (1) incorporating survey data to modify channel geometry; (2) calibrating a model using known water surface elevations; (3) designing a stream crossing through model iteration; (4) running a multiple opening stream crossing analysis; (5) computing bridge scour; (6) exploring RAS Mapper for results analysis and visualization; and (7) building a 1D hydraulic model in RAS Mapper. A brief description of 2D modeling capabilities in HEC-RAS 5.0.6 will also be presented, including an example project. HEC-RAS tools and techniques will be discussed and explored interactively throughout the workshop. Participants will be provided with electronic files of partial HEC-RAS models ahead of time, therefore emphasizing HEC-RAS applications rather than full model development.

This is a hands-on workshop so it is required that all participants bring a laptop with HEC-RAS downloaded ahead of time. Version 5.0.6 is the newest release, which is the preferred version for this workshop. Go to: http://www.hec.usace.army.mil/software/hec-ras/downloads.aspx to download the latest version a week before the class takes place. Prior experience with HEC RAS is required. We strongly recommend taking the Hydraulic Modeling: Introduction to HEC RAS class first.

Kevin Waters

Kevin Waters, Ph.D., P.E. is the instructor for this one-day workshop. Dr. Waters is an Assistant Professor in the Department of Civil and Environmental Engineering at Villanova University where he teaches water resources courses at the undergraduate and graduate levels. He has over 4.5 years of consulting experience, most recently as a Water Resources Engineer with Amec Foster Wheeler in Chantilly, VA. In this position, he worked extensively with HEC-RAS and ArcGIS to conduct flood studies and flood impact analyses, in addition to leading an initiative to explore two-dimensional floodplain modeling capabilities in the newest version of HEC-RAS.

During his two years as a Senior Engineer at T.Y. Lin International-Medina in New Jersey, he developed HEC-RAS models for flood studies in support of FEMA’s National Flood Insurance Program, including work on a 125-mile study of the Delaware River and several streams in Erie County, NY. In total, Dr. Waters has modeled and reviewed hundreds of miles of modeled streams in VA, WV, MD, NY, NJ, and MO.

Dr. Waters completed his Ph.D. in Civil Engineering at the University of Virginia in 2014 with research focused in open channel hydraulics and sediment transport in unsteady flows. He earned his M.E in Civil Engineering from the Stevens Institute of Technology in Hoboken, NJ, with a concentration in water resources, and a B.S. in Civil Engineering from Villanova University in 2007.
