Learning Outcomes

  • Students will learn how to use the U.S. Army Corps of Engineers’ HEC-RAS (River Analysis System) computer program to conduct dam breach analyses. Assessment Criteria: Students will work in pairs to create several HEC-RAS Dam Breach
    models
  • Students will gain hands-on HEC-RAS experience with the most common problems that arise when doing a dam breach model. Assessment Criteria: Students will participate in practical computer workshops using HEC-RAS and will be tasked with setting up the models, running them, and analyzing results
  • Students will gain an overview of hydraulic principles for rivers, waterway bridges, and culverts and how they work within a dam breach model. Assessment Criteria: Students will work in pairs to gain hands-on experience with HEC-RAS that will require them to understand and apply hydraulic principles discussed in class
  • Students will gain understanding of breaching parameters and how to choose them. Assessment Criteria: Students will work in pairs to gain hands-on experience with HEC-RAS that involves selecting and applying dam breach parameters to the model
  • Students will obtain valuable insights in methods for minimizing computation errors and instabilities commonly associated with unsteady hydraulic models Assessment Criteria: Students will work in pairs to gain hands-on experience with HEC-RAS that involves setting up a dam breach HEC-RAS model, diagnosing instabilities and errors with dam breach models, and fixing dam breach models

Assessment of Learning Outcomes

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

Special Features

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 as workshop solution files. Computers provided – 1 per 2 participants to share.

Who Should Attend?

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

Purpose and Background

This intensive, workshop-oriented, three-day seminar will prepare the engineer and water resource professional to use the HEC-RAS computer program for running dam breach simulations. Led by experts from WEST Consultants with practical experience in dam breach modeling, participants will learn how to approach and conduct a dam breach problem, estimate breaching parameters, construct a HEC-RAS unsteady flow model of the dam breach, and eliminate errors and instabilities in the model run.

The HEC-RAS modeling system was developed as part of the Hydrologic Engineering Center’s “Next Generation” software and replaces several existing Corps of Engineers programs, including the HEC-2 water surface profile program. HEC-RAS incorporates various aspects of hydraulic modeling, including water surface profile computations and bridge hydraulics.

Includes advances in open channel hydraulic analysis such as:

  • Dam and Levee Breach Analysis including multiple dam and/or levee breaching
  • Availability of all widely used methods for bridge and culvert hydraulic analysis, which can be used in conjunction with dam breaching
  • Ability to perform steady and unsteady mixed flow regime computations
  • Many other capabilities developed from years of experience with HEC-2 and other major hydraulic analysis computer programs

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 Hydrologic Engineering Center and at other Corps of Engineers’ 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.
