A concrete gravity dam is 120 m (394 ft) high with an upstream slope of 1H:10V and a downstream slope of 1H:1V. The uplift varies linearly from zero at the downstream toe to full hydrostatic pressure at the upstream toe. Compute the overturning moment if the water depth in the reservoir is 100 m (328 ft). The top width of the dam is 10.0 m (32.8 ft), and specific gravity of the concrete is 2.40. Compute the righting moment for the dam and compare the two moments.
