Embankment-Dam Breach Parameters

by David C. Froehlich, US Geological Survey, Denver, CO, USA,

Document Type: Proceeding Paper

Part of: Hydraulic Engineering


The study used data from 43 embankment-dam failures to develop equations that predict breach formation model parameters. These data include the failure mode, embankment characteristics, reservoir conditions at the time of failure, geometry of the final breach, and the time taken to form the breach. Regression equations were developed to predict (1) the average width of a trapezoidal breach, (2) the average side-slope factor of a trapezoidal breach, and (3) the breach formation time.
