Gravity Dam; Its Construction, Advantages and Disadvantages.

Calculate the seepage through a gravity dam using mathematical principles.

1.A gravity dam shown in Figure 3 with a horizontal base is 25m high and has a thickness of 5m at the top. The water upstream stands 3m below the crest of the dam. The specific gravity of the concrete is 2.4. Considering the uplift pressure to vary uniformly from full hydrostatic pressure at the heel to zero at the toe.A.Find the base width B of the dam so that the resultant force will act at the extremity of the middle third near the toe.B. Compute the maximum and minimum compressive stresses a
