| Q.55 | A homogeneous anisotropic earth dam, which is 23 m high, is constructed on an impermeable foundation. The water level on the reservoir side is 20 m from the base of the dam, downstream side is dry. It is seen that there are 4 flow channels and 16 equipotential drops in a square flow net drawn in the transformed dam section. Estimate the quantity of seepage per unit length in m3/s through the dam. Consider the value of the coefficient of permeability (after accounting the coefficient of permeability in both horizontal and vertical directions) as 3.0 × 10-8 m/s. | |
| Ans | A. 2.6 × 10-7 m3/s/m run | |
| B. 1.5 × 10-7 m3/s/m run | ||
| C. 1.8 × 10-7 m3/s/m run | ||
| D. 1.2 × 10-7 m3/s/m run |
Correct Ans Provided: B
