GIS Applications for Hydraulic and Hydrologic Modeling

As recognized experts in the application of Geographic Information Systems (GIS) in support of hydraulic and hydrologic computer models, WEST Consultants routinely offers training courses on a national and international basis to government agencies and private industry organizations, including courses on the use of the ArcGIS extensions ArcHydro and HEC-GeoHMS. WEST’s instructors all have extensive application experience with these and other GIS applications in support of hydraulic and hydrologic modeling.

WEST provides the GIS Applications for Hydraulic and Hydrologic Modeling class in both our standard 2-day course format as well as customizations to meet our client’s needs (also taught in combination with the HEC-RAS: Basic Hydraulic Modeling for Steady Flow Analysis).

WEST’s hands-on seminar and computer workshop provides practical training in the application of the ArcGIS extensions ArcHydro and HEC-GeoHMS. GIS data models and concepts supporting hydrologic modeling are also discussed. The seminar is taught by experts with practical experience in GIS and hydrologic modeling. Seminar participants will learn how to process data and create hydro networks using ArcHydro, build a project in HEC-GeoHMS and prepare the data files for HEC-HMS, and set up projects within the HEC-HMS environments.

ArcHydro is a set of tools for extracting hydrologic data from a digital elevation model (DEM) in the ArcMap application. These data include watershed boundaries, stream networks, and other watershed parameters used for the development of hydrologic models. ArcHydro is the preprocessor for HEC-GeoHMS. HEC-GeoHMS prepares the layers generated by ArcHydro for use in the HEC-HMS hydrologic program. In combination with GIS data layers for soils, land cover, and rainfall, HEC-GeoHMS has several widely used methods available for computing loss parameters for input into the HEC-HMS program.


“This course is just right for modelers wanting to bring ArcHydro, HEC-RAS and HEC-HMS together and advance to the next level.”
– Jean Thibodeaux, J Thibodeaux & Associates, Covington, LA

“I really enjoyed the seminar and thought it was well organized.”
– Pete Rogers, University of Texas at Tyler, Tyler, TX

“Very good instructor and very good class.”
– Mary Ann Lind, DMK Associates, Venice, FL
