Question

A permeable soil layer is underlain by an impervious layer as shown in Figure 7.29. Knowing that k = 6 × 10 −3 cm/sec for the permeable layer, calculate the rate of seepage through this layer in m 3 /hr/m width. Given: H = 5.4 m and α = 7°.

​

Answer 1

Explanation:

Find the rate of flow in m3/sec/m (at right angles to the cross section shown in Figure 7.33) through the permeable soil layer. Given: H = 4 m, H1 = 2 m, h = 2.75 m, S = 30 m, a = 14°, and k = 0.075 cm/sec.
