The objective of the course is for participants to perform hydrologic and hydraulic modeling in support of Dam Safety studies. Topics presented will include: Development of Probable Maximum Precipitation (PMP); Using GIS to Develop a Hydrologic Model; Hydrologic Modeling for PMP/PMF Events; Developing Dam Breach Parameters; Dam Breaching Analysis using HEC-HMS and HEC-RAS; Unsteady Flow Modeling with HEC-RAS; using HEC-GeoRAS and RAS Mapper for Inundation Mapping; and Consequence Modeling. Each participant will have the opportunity to prepare model input and analyze model output during course workshops.

Through a series of lectures and hands-on workshops, the students will learn about development of extreme storm events and hydrologic and hydraulic analysis methods using HEC-HMS and HEC-RAS software to simulate inflow design floods to assess spillway adequacy, and to evaluate dam-break consequences. Other topics will include: severe storm magnitude and sequence analysis; hydrologic simulation of inflow to dam and downstream tributaries; spillway sizing and operation; hydraulic calculations of flow through dam outlets; estimating dam breach parameters; dam breaching analysis; hydraulic routing of dam break flood waves; how to solve model stability problems when performing a dam break analysis; inundation mapping; and consequence modeling.

Nominees must be assigned (a) Occupational series: Selected 0800 and 1300 (b) Grade: GS-07 or above (c) Prior courses: Basic HEC-HMS (#178) and HEC-RAS (#114) or equivalent knowledge; and (d) Familiarity working in a Windows-based computer system environment. Basic HEC-HMS and HEC-RAS input will not be covered. Prior experience with unsteady flow routing is recommended.
