Abstract/Additional Information

A technical note that uses empirical data to estimate breach paramters for embankment dams. Database used includes 57 dam failures tabulated by Froehlich (1987) MacDonald & Langridge-Monopolis (1984), 37 of which were 30 feet or more in height. Recommendations are primarily for dams over 30 feet or more in height. Guidance for assumed trapezoidal breach geometry includes side slope angles, breach width at mid-height, and time of failure.
