Question
Subject soil Mechanics

Transcribed Image Text: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 102 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.
(B) How high should the river rise (elevation with respect to the undisclosed datum) to
reduce the water loss in half?
