INSTRUCTOR: 
Keelan Jensen

*Should one of the above instructors be unavailable to teach, a qualified WEST Consultants instructor will be appointed to replace him.

*We highly recommend individuals have previous HEC-RAS experience. This is not an introductory course.

This is a hands-on seminar. You must bring your own laptop.

Purpose and Background

This intensive, workshop-oriented, two-day course will prepare the engineer and water resource professional to use the HEC-RAS computer program for modeling two-dimensional (2D) unsteady flow applications. Led by experts from WEST Consultants with practical experience in hydraulic modeling, participants will learn how to approach and construct a 2D model for unsteady flow conditions, and to effectively view and analyze results. The seminar includes lectures on 2D flow theory, an introduction to the new capabilities and features of HEC-RAS, and procedures for creating a stable and calibrated 2D model. Workshops focus on giving students hands-on experience with building and pre-processing the computational mesh, performing offline and inline 2D projects, and using the built-in feature RAS Mapper to spatially analyze results.

The HEC-RAS modeling system was developed as part of the Corps of Engineers Hydrologic Engineering Center Next Generation software and replaces several existing programs including HEC-2, UNET, and HEC-6. HEC-RAS incorporates various aspects of 2D hydraulic modeling, including flow and water surface profile and computations within storage areas, and the interaction between 1D and 2D systems. Version 5.0 of HEC-RAS includes features in 2D open channel hydraulic analysis such as:

• Two-dimensional flow analysis using the full St. Venant or diffusion wave equations in 2D.
• Ability to perform a combination of 1D and 2D flow analysis in the same model.
• The use of unstructured or structured computational meshes for the 2D flow areas.

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 online help.

Benefits and Learning Outcomes

Upon completion of this course, you will be able to:

• Use the U.S. Army Corps of Engineers HEC-RAS (River Analysis System) computer program to model two-dimensional unsteady flow hydraulics.
• Explain two-dimensional flow theory and the differences between one-dimensional modeling.
• Apply your HEC-RAS experience by participating in practical computer workshops.
• Develop a stable and calibrated two-dimensional flow model.
• Utilize methods for minimizing computation errors and instabilities for two-dimensional unsteady hydraulic models.

Special Features

Via email, approximately 5 days prior to the seminar, workshop participants receive links to download the following publications and software:

• HEC-RAS software (latest version)
• HEC-RAS Course Notes and Workshop Problems
• HEC-RAS User Manual
• HEC-RAS Hydraulic Reference Manual
• HEC-RAS Applications Manual
• HEC-RAS Hydraulic Reference Manual
• HEC-RAS Example Problems

Assessment of Learning Outcomes

Students' achievement of the learning outcomes will be assessed via a short post-test assessment (true-false, multiple choice, and/or fill in the blank questions).

Who Should Attend?

Consulting engineers, water resource planners, engineers employed by local, state, or federal government agencies. Participants should have some experience in floodplain hydrology and hydraulics, and sound experience in HEC-RAS steady and unsteady flow computer modeling. They should also be able to follow simple computer instructions.
