A masonry dam of trapezoidal cross section, with one face vertical has a thickness of 60 cm at the top, 3.70 m at the base, and has a height of 7.40 m. What is the depth of water on the vertical face if the resultant intersects the base at the downstream edge of the middle third? Assume that the uplift pressure varies uniformly from full hydrostatic at the heel to zero at the toe. Unit weight of concrete and masonry is 23.54 kN/m3 NOTE: CLEAR HANDWRITTEN SOLUTION
