Course Descriptions & Materials

Hydrologic Engineering Applications of Geographic Information Systems (April 2015) This course provides instruction in the application of GIS technologies for watershed and stream network delineation, computation of watershed and stream characteristics, hydrologic parameter estimation, development of the channel geometry for a 1-dimensional river hydraulics model, and mapping of water depths. Hands-on experience in applying ArcGIS and HEC products, HEC-GeoHMS and HEC-GeoRAS, to perform such analyses is included. Download of available course materials is provided below. The lectures and workshops utilize ArcGIS 10.2, HEC-GeoHMS 10.2, and HEC-GeoRAS 10.2. Versions 10.2 of HEC-GeoHMS and HEC-GeoRAS are available from the HEC webpage. Other versions of HEC-GeoHMS and HEC-GeoRAS can be used for the workshops; however, the workshops were specifically designed using the 10.2 versions and there might be some problems encountered when using older or newer versions of the software. Some workshops were designed to be placed in a specific directory on a computer, the directory is included in the workshop instructions. HEC is in the process of integrating GIS capabilities directly within HEC-RAS and HEC-HMS. These capabilities will replace HEC-GeoHMS and HEC-GeoRAS and the training material will be updated.

Hydrologic Modeling with HEC-HMS (December 2015) This course serves as an introduction to hydrologic modeling and application of the Hydrologic Engineering Center's Hydrologic Modeling System (HEC-HMS) and covers topics of precipitation, infiltration, surface runoff, channel routing, and parameter estimation. Knowledge gained in lectures is applied by using HEC-HMS to simulate these processes within the context of the watershed. Each segment of the class is part of a hypothetical case study where students learn the basic steps in developing an HEC-HMS model. Download of available course materials is provided below. The workshops were developed using HEC-HMS Version 4.1, and more recent versions of HEC-HMS can be used with the workshops as well.

HEC Workshop Materials

Basic HEC-HMS Workshop (First European HEC Workshop, October 2016) This workshop walks a participant through the basic steps of setting up an HEC-HMS model and calibrating the model to observed flood events. The new uncertainty analysis compute option is contained in the workshop as well. Download of available course materials is provided below.
