In general, considering investigated cases, it can be said that reservoir rapid discharge leads to decreased stability of earth dam
, especially in the upstream slope of the dam.
Most engineers consider the seismic coefficient as a means of designating the magnitude of a static force which is equivalent in effects (i.e., produces the same deformations of the earth dam
) to the actual dynamic inertia forces induced by the earthquake.
