Studied herein is theoretical mechanism of the failure of an embankment caused by overflowing from a reservoir. An experiment has been conducted to observe the phenomenon, and the theory of the mechanism has been developed on the basis of the erosion and the stability of the slope subjected to the erosion. Shallow water equation considering the slope angle has been used to describe the erosion, and Mohr-Coulomb failure criterion has been applied to the stability analysis. The results allow the surface profile and the erosional speed to be determined as functions of imposed parameters. At the end of this paper, we have discussed the scope of application, and examined the theory by an additional experiment.
