Course Descriptions & Materials

Advanced 1D 2D Unsteady Flow Modeling (July 2017) This is an advanced course in applying the computer program HEC-RAS. The course provides participants with the knowledge to effectively use HEC-RAS to analyze difficult hydraulic conditions in natural and constructed channels, utilizing one-dimensional (1D) and two-dimensional (2D) modeling techniques. Topics include: developing terrain models for 2D modeling; creating a 2D computational mesh; boundary conditions for 2D flow areas; hooking up 1D elements to 2D flow areas; running a combined 1D/2D model; viewing 1D/2D results with RAS Mapper; hydraulic structures inside of 2D areas; and detailed channel and floodplain modeling with 2D flow areas. Special topics for dam and levee breaching and using 2D modeling for hydraulic structures are included as well. HEC-RAS version 5.0.3, or a more recent version, should be used when working through the workshop examples. Due to file size, some of the solution files were deleted prior to posting the material to the website. The solution projects should be re-run using HEC-RAS 5.0.3 to generate results for comparison to the workshop solutions.

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.

Unsteady Flow Analysis Using HEC-RAS (January 2016) This course provides instruction to effectively utilize the Hydrologic Engineering Center's River Analysis System (HEC-RAS) software to analyze hydraulic conditions that require one-dimensional unsteady flow modeling. Topics include river mechanics and the unsteady flow equations; using HEC-DSS data with HEC-RAS; overview of unsteady flow modeling; data requirements for unsteady flow models; boundary and initial conditions; overview of model output; modeling bridges and culverts; inline and lateral hydraulic structures; storage areas and storage area connections; model calibration; model stability, accuracy, and sensitivity; trouble shooting; modeling urban areas; and advanced features for unsteady flow (mixed flow regime, pump stations, dam and levee breaching). HEC-RAS version 5.0.3, or a more recent version, should be used when working through the workshop examples.

HEC Workshop Materials

Workshop: Application of HEC software to Periodic Assessment Studies A series of lectures and workshops were developed for the USACE Dam Safety program to illustrate periodic assessment level of analysis and application of HEC software. The material was posted for the user community to see additional examples for how to apply both HEC-SSP and HEC-HMS to typical study applications. The training material contains publically available information and results presented in the workshops are only for learning purposes, the results do not reflect actual design events. HEC-SSP version 2.1.1 and HEC-HMS 4.2.1 were used in the development of the workshops.

Workshop: Application of HEC-HMS Using Gridded Precipitation in Watersheds Outside of the United States (May 2017) This workshop is designed to help users applying HEC-GeoHMS and HEC-HMS in watersheds outside of the United States. In particular, this workshop will demonstrate the application of gridded precipitation within HEC-HMS outside of the regions covered by the HRAP and SHG grid systems. Prior to HEC-HMS version 4.2, it was not possible to utilize the gridded precipitation option in HEC-HMS for areas outside of the U.S. due to limitations in how gridded data was stored in HEC-DSS.
