Question
1. Calculate the equivalent hydraulic conductivity for the soil profile shown in figure
2. An excavation is proposed for a square area near the bend of a river, as shown in figure. It is expected that the flow of water into the excavation will come through the silt layer. Pumping test reveal an average horizontal hydraulic conductivity of 2 x 10 -5 cm/s in the silt layer. The excavation has to be kept dry. Determine the flow (qs) into the excavation.
