Q1 7.5/8 Refer to the flow net below. Given the following information, the head in the reservoir is 86.0m and the head in the tailwater is 62.0 m; the dam is 312m long in the direction normal to the flow net. Assume the material under the dam is isotropic with K=0.06 m/day and porosity of 0.1. Water density is 1000 kg/m3, saturated soil density is 2000 kg/m3 1. Estimate the total discharge through the layer under this dam 2. Estimate the Darcy's velocity from point A to B (distance A-B is appr. 12m) 3. Estimate linear velocity from point A to B 4. Estimate the effective stress at C (depth of C is app 15m)
