Technical Abstract: Two primary causes of earthen embankment dam failure are overtopping and internal erosion. For the purpose of evaluating dam safety for existing earthen embankment dams and proposed earthen embankment dams, WinDAM (Windows Dam Analysis Modules) was developed through the cooperative efforts of the USDA-Agricultural Research Service, the USDA-Natural Resources Conservation Service, and Kansas State University. WinDAM is a single event model that routes a user-supplied hydrograph through a dam. WinDAM software estimates embankment erosion during an overtopping event or from internal erosion flow. The resulting WinDAM hydrograph output includes the outflow resulting from possible breaching of the embankment. This WinDAM output hydrograph can then be exported to other hydraulic software for estimating downstream flooding impacts. Earthen embankments with bare soil, vegetation, or rock riprap can be evaluated with WinDAM software. The workshop is directed toward engineers with some background in hydraulics and or geotechnical engineering.
