The figure below shows the soil profile conditions below a 5-m deep pond. Water is seeping directly downward under steady-state conditions through the clay layer into underlying gravel. Assume the elevation datum at the top of the gravel layer and that the hydrostatic ground water table is also found in the top of the gravel and its position does not change with time or amount of flow. For these flow conditions, calculate the following: a. b. c. d. e. f....
