Question 31 A flownet is given below for flow under a concrete dam. The dam is 100 m long and has two 10 m sheet piles driven partially into the granular soil layer. The datum is at the surface of impervious bedrock, shown in the figure. The water level is H = 8 m above soil layer in the upstream and at the soil layer surface in the downstream. Calculate the uplift pressure at Point E under the dam.
