Course Objectives

This course consists of a three-day introduction of HEC-RAS and a one-day introduction to HEC-RAS 2D, with applications to dam safety.  The first three days provide hands on opportunity to use the program and resolve specific questions.  The objective of this part of the course is to review the basic principles of open channel hydraulics as they relate to the natural stream environment with application to dam safety.  Bridges, culverts and in-line structures will be discussed and both steady and unsteady flow modeling will be explored.

HEC-RAS 2D represents the most significant advancement of HEC-RAS in the last decade and includes many new features that will allow users to more accurately and more efficiently map the consequences of potential dam failures for hazard classification and emergency action planning.  The goal of the fourth day presentation is to instruct students on the basic capabilities of the HEC-RAS 2D model.  Due to the limited time available in this segment, detailed instruction on how to develop a new 2D model is not provided.   Students will become familiar with the data requirements and general process of 2D modeling and will have the opportunity to explore a simple 2D model.

Specific objectives will be to:

  • Apply the principles to model a dam break
  • Identify the data requirements for modeling
  • Create the appropriate files for HEC-RAS
  • Develop the appropriate boundary conditions
  • Extract and analyze hydraulic output.
  • Obtain an understanding of 1D/2D unsteady flow modeling with HEC-RAS
  • Understand how to use 2D flow areas within HEC-RAS

The participants should have an undergraduate engineering degree.

Course Materials

The manual consists of a pdf of the power point slides including the note pages. A Word file of the workshops and their solutions is also included in the notes. A CD of the manual, workshops, and computer solutions to the workshops will be given to the participants at the beginning of the course.
