H&H for Dam Safety Studies
Objectives
The objective of the course is for participants to perform hydrologic and hydraulic modeling in support of Dam Safety studies. Course participants will be required to run HEC-HMS, HEC-SSP, and HEC-RAS.
Topics presented will include: Development of Probable Maximum Precipitation (PMP); Hydrologic Modeling for PMP/PMF Events; Hydrologic Loading; Flow Frequency; HEC-RAS Model Geometry Development, Developing Dam Breach Parameters; Dam Breaching Analysis using HEC-RAS; Unsteady Flow Modeling with HEC-RAS; and Using RAS-Mapper for Inundation Mapping. Each participant will have the opportunity to prepare model input and analyze model output during course workshops.
Prerequisites
Students who come to this class should have knowledge on how to use HEC-HMS and HEC-RAS. This knowledge can be in the form of a basic training class or on the job experience. The preparation of basic input data and analysis of the output from these software packages will not be covered. Experience in unsteady flow modeling is a plus but is not required.
