A flow net is drawn for seepage through homogeneous, isotropic soil beneath an impermeable concrete dam as shown. Beneath the soil lies impermeable bedrock. The upstream water level, H₁, is 3 m above the top of the soil, and the downstream water level, H2, is 1 m above the top of the soil. The soil's coefficient of permeability, k, is 3 x 10-2 cm/s. informa- upstream -impermeable dam 000 peo- pment is 2 H₁ downstream H₂ = 1 3 42 9. 6: 10 his hous- e soil housing impermeable bedrock 17. The rate of flow per lineal meter of dam width is most nearly (A) 3 x 10-1 m2/s (B) 5 x 10-3 m²/s 3/s be- idge A, 150 m², cross- elocity (C) 2 x 10-2 m2/s (D) 2 x 10-1 m2/s 18. If the dam is 10 m wide, the total flow rate of water passing underneath the entire dam is most nearly (A) 3 x 10-3 m³/s (B) 5 x 10-2 m³/s (C) 2x 10-1 m³/s (D) 2 m³/s Problems 19-21 are based on the following information and illustration. A 10 m thick clay layer lies between two soil layers as shown. The coefficient of consolidation
