WebIt will be considerable pressure on the retaining wall. For example, when we take soil pressure for friction angle 30 degrees, it is 0.33 x 20 h = 6.67h. The water pressure will be 10h. Here, soil density considered as 20 kN/m3. Sol pressure without water = 6.67 h. With water = 0.33 (20 -10) h + 10 h = 13.3 h.
