3. The flow net shown below illustrates flow conditions beneath a concrete dam featuring an upstream "clay blanket" (an impermeable clay layer) and a downstream "cutoff wall", both of which serve to lengthen the flow path. The coefficient of permeability, k, of the permeable strata is 8 x 10 cm/s. a. Calculate the flow rate, q, per day beneath the dam (per m of dam out-of-plane). b. Calculate the total head, elevation head, pressure head, and pore water pressure at...

Q.5) Water backs up behind a concrete dam as shown in Figure below. Leakage under the foundation gives a linear pressure distribution under the base of the concrete dam as shown in Figure. If the water depth H, is too great, the dam will topple over about its toe (Point A). For the dimensions given, determine the maximum water depth. Base your analysis on a unit length of the dam. The specific weight of the concrete is 23.7 kN/m”. (Answer...
