A canal is constructed parallel to a river 600 m away both fully penetrating an unconfined aquifer of coarse sand and fine gravel as shown in the illustration below. The aquifer is subject to an average infiltration of 2.3 m/year. The water surface elevation in the river is 10 m. The Acme Chemical Co. is concerned about its discharges possibly contaminating the river, and has hired you to design the canal to prevent river contamination. Assuming the contamination is likely within 350 m of the canal, (a) determine the maximum water surface elevation in the canal to that will prevent river contamination, (b) determine the daily discharge of groundwater into the canal and into the river per kilometer of both; and (c) estimate the travel times from the water divide to the canal and to the river.
