For triangular dam section of height H for just no tension under the action of water pressure, self-weight and uplift pressure, the minimum base width required is _____________ Correct Answer H / (S-1)1/2

The minimum base width (B) of a gravity dam having an elementary profile – B = H / (S – 1)-1 where S is specific gravity of concrete and H is the height of water. If uplift is not considered – B = H/S1/2.
