Analysis of Gradual Earth‐Dam Failure
Publication: Journal of Hydraulic Engineering
Volume 114, Issue 1
Abstract
Analytical models are developed for the simulation of earthdam breach erosion. Using a reservoir water‐mass depletion equation, broad‐crested weir hydraulics and a breach‐erosion relation, solutions are derived for rectangular, triangular, and trapezoidal‐shaped breaches. Breach erosion is assumed to be either a linear or quadratic function of the outflow mean water velocity. Historical data are used to test the models. A sensitivity analysis is performed to determine the importance of the various parameters involved.
