Failure occurred in the vicinity of the principal spillway $12$ years

after construction. The embankment is approximately $576$ m

long and $15\mathrm{.}6$ m high. The failure occurred at normal pool.

$17,500,000m^3$ of water was released. $23$ km of valley to depths

of up to $10\mathrm{.}0$ m from the dam to the Pearl River.

Determine the magnitude of the resultant force exerted by the

water on the submerged plane where failure occurred and its

point of application. Assume the dam is rectangular.
