Great course for understanding the do’s and don’ts of sediment transport analysis. Instructors did a good job of tying concepts to real world examples.  Scott Lyle, Lyle Engineering, Inc., Carlsbad, CA

This intensive three-day seminar will prepare the engineer and water resource professional to use the HEC-RAS computer program for running sediment transport analyses. Led by experts from WEST Consultants with practical experience in sediment transport modeling, participants will learn how to approach and conduct a sediment transport study using HEC-RAS, including handling input parameters and boundary conditions, selecting a transport function, and performing calibration and sensitivity analyses.

The HEC-RAS modeling system was developed as part of the Next Generation software from the Hydrologic Engineering Center and replaces several existing Corps of Engineers programs, including the HEC-2 water surface profile program. Beginning with version 4.0 of HEC-RAS, the U.S. Army Corps of Engineers incorporated various new aspects of hydraulic modeling, including, for the first time, sediment transport modeling.

The latest version of HEC-RAS includes advances in open channel hydraulic and sedimentation analysis such as:

• Sediment Transport/Movable Bed Modeling
• Sediment Impact Analysis Methods (SIAM)
• Stable Channel Design Tools

HEC-RAS is user friendly, computationally efficient, and runs within, and fully supports, the Microsoft Windows environment. It uses the latest graphical user interface (GUI) technology for data entry, graphics, and display of program results. Complete context-sensitive help screens are available for every program feature and option. Software includes the following functions: file management, data entry and editing, hydraulic analyses, tabulation and graphical displays of input and output data, reporting facilities, and on-line help.

HEC-RAS is one of the most extensively-tested civil engineering computer programs ever developed. In addition to extensive in-house testing at the Corps of Engineers Hydrologic Engineering Center offices, the program has been through two full beta releases, during which the program was tested by thousands of engineers in the private and public sectors.

NOTE: Participants need a thorough understanding of open channel hydraulics; particularly the assumptions, limitations, and use of procedures for computing open channel flow properties such as water surface elevation and velocity. Participants should be familiar with running HEC-RAS for steady flow analyses.

Students will be able to:

• Set up and execute a sediment transport analysis within HEC-RAS
• Recognize the various sediment transport methods within HEC-RAS and select appropriate function(s)
• Apply calibration and sensitivity techniques to their models
• Troubleshoot HEC-RAS sediment models

Instructor(s) will observe student performance during multiple computer workshop problems. Students will take a test at the end of the class with questions addressing the Learning Outcomes. The test will be graded in class by their classmates as the instructor goes over each question and answer.

Workshop participants will receive a CD containing the HEC-RAS software, the manuals in PDF format (User's Manual, Hydraulic Reference Manual, and Applications Guide), input files for the workshops, as well s workshop solution files.

Workshop participants receive the following publications and software:

• HEC-RAS software (latest version)
• HEC-RAS Hydraulic Reference Manual (on CD)
• HEC-RAS User’s Manual (on CD)
• HEC-RAS Course Notes
• HEC-RAS Applications Manual (on CD)

Consulting engineers, water resource planners, engineers employed by local, state, or federal government agencies who currently execute and/or review sedimentation studies or plan to in the future. Participants should have sound experience in HEC-RAS steady flow computer modeling. They should also be able to follow simple computer instructions.
