This course focuses on the use of the computer program HEC-RAS for the analysis of one-dimensional gradually varied unsteady open channel flow. The role and application of this model in Corps flood studies is presented in lectures, workshops and examples.

Primary coverage is on one-dimensional open channel hydraulics. This covers the theory, applicability, limitations, and data requirements of the HEC-RAS unsteady flow program. Additional topics include: modeling bridges and culverts, inline and lateral hydraulic structures, storage areas, model calibration, model stability and accuracy, trouble shooting, and advanced features for Unsteady Flow Modeling (mixed flow regime, pump stations, dam and levee breaching). Case studies and computer workshops are used to illustrate model usage.

Nominees must be assigned (a) Occupational Series: Selected 0810 and 1300; (b) Grade: GS-07 or above. Nominees must have a good background in open channel hydraulics and familiarity with HEC-RAS. Basic HEC-RAS input and output data requirements will not be covered in this class. It will be assumed that you already know how to use the software for performing a steady flow analysis. Familiarity with the partial differential equations of fluid motion and numerical solution techniques is desirable. Participants should be in positions requiring analysis of complex hydraulic problems. Students should have at least one (1) college level class in open channel hydraulics.
