The dam shown has a base of which 2 m. below the ground surface. The pressure distribution diagram at the base of the dam can be obtained from the equipotential lines as follows: m P +15 mt K = 4.5 m/day. If H = 6 m, Determine the seepage through the foundation Select the correct response: 27.88 m/day 65.33 m/day 13.71 m/day 10.29 m/day

CALCULATION USING DARCY'S LAW An aquifer system is formed by two horizontal layers. Two piezometers were installed for monitoring, the distance between them is 885m. The upper layer (A) has a thickness of 39m and K = 1.3 x 10-5 m/s and the lower layer (B) has a thickness of 25m and K = 2.7 x 10-6 m/s. THE hydraulic load in the PZA is 60m and in the PZB it is 40m. Calculate the flow and the transmissivity of each layer.

Please do it in a complete way, so I can easily understand it. Thank you to all of you

Calculate the effective hydraulic conductivity for flow parallel and perpendicular to layering. Please show and explain the difference in values.

The water table is lowered from a depth of 10 ft to a depth of 20 ft in a deposit of silt. All the silt is saturated even after the water table is lowered. Its water content is 26%. Estimate the increase in the effective pressure at a depth of 34 ft on account of lowering the water table. Assume G, = 2.7. 34 ft 20 ft 10 ft 10 ft Silt deposit Figure Ex. 5.7 Original G.W.L.
