An unlined irrigation canal has been aligned parallel to a river, as shown (next page). This cross-section continues for 5.25 miles (length of irrigation canal). The predominant soils are generally clayey soils with extremely low permeability, but the geotechnical engineer realized that a 6 in thick sand seam is present as shown (thickness perpendicular to the flow). The sand has a hydraulic conductivity of 8.2 x 10 cm/sec. (A) Compute the water loss from the canal to the river due to seepage through this sand layer and express your answer in acre-foot per month. Note: One acre-foot is the amount of water that would cover one acre of ground to a depth of one foot, and thus equals 43,560 ft.
