The dam for a lake is designed to withstand the additional force caused  by silt that has settled on the lake bottom. Assuming that silt is equivalent to a liquid of density ρs = 1.76 X 10 kg/m' and considering a l-m-wide section of dam. determine the percentage increase in the force acting on the dam face for a silt accumulation of depth 2 m.
