Abstract
Computer programs developed for dam safety analyses are limited by the accuracy of the input data for the geometric and temporal dam breach characteristics. Data on a number of historical dam failures were collected and analyzed and graphical relationships for predicting breach characteristics were developed for erosion type breaches. The data provides a basis for selecting a breach shape and calculating the breach size and the time for breach development. A relationship is also developed for estimating peak outflows from dam failures. This relationship can be used to verify the methodology and the results of dam safety studies.Keywords
