Floodplain Delineation with HEC-RAS and GIS Workshop set

Civil engineers and floodplain managers can learn about a U.S. Army Corps of Engineers software program that assists in floodplain analysis at a Texas Water Resources Institute workshop in August in Dallas.

The TWRI workshop on August 24-26 at the Texas AgriLife Research and Extension Urban Solutions Center will focus on the fundamental concepts of open-channel hydraulics and control sections and include hands-on applications of the U.S. Army Corps of Engineers Hydrologic Engineering Center’s HEC-RAS and HEC-GeoRAS software packages.

With ever-increased property losses due to flood damage, floodplain management and flood hazard mapping are becoming more critical for hazard managers. The HEC-RAS software program is widely used for various open-channel hydraulics analysis and design tasks. In addition, the HEC-GeoRAS program—used to develop and map the results of HEC-RAS analyses—is a very popular add-on within the ArcGIS platform.

Participants will learn the latest techniques of floodplain mapping, discuss the differences between steady and unsteady flow simulations, and become familiar with HEC-GeoRAS mapping procedures.

The workshop will be instructed by Dr. Francisco Olivera, P.E. and Matthew Zeve, P.E., CFM. Olivera is an associate professor of civil engineering at Texas A&M University and has more than 25 years of experience in water resources engineering and more than 12 years on the use of GIS for hydrologic and hydraulic modeling.

Zeve is a senior project manager in the Houston office of TCB/AECOM., a multi-disciplinary consulting firm. Zeve has more than seven years of experience in water resources analysis and planning. He has worked on numerous large and complex hydrologic and hydraulic projects. In addition to his project responsibilities, Zeve has four years of experience in teaching hydrologic and hydraulic software and technical material to public and private entities.
