Technical Abstract: The USDA has partnered with landowners to build rural flood control dams. Overtopping and internal erosion are the causes of most dam failures. To estimate the peak discharge associated with a dam incident, the USDA-NRCS, -ARS, and Kansas State University have collaboratively developed software. The next expected release, WinDAM C, will analyze breach by internal erosion, in addition to overtopping and auxiliary spillway analysis currently availabe in WinDAM B. The Internal erosion conduit is simulated as rectangluar in cross section, horizontal and perpendicular to longitudinal axis of crest. Erosion is simulated as occuring by detachment along conduit length and by head cut advance at outlet. User must define the conduit's initial geometry, dam geomety and material properties, and reservoir storage and inflow. A wide array of outputs are genearted including peak discharge and time of peak discharge.
