using darcy's law compute the quantity of flow, seepage velocity and contaminant loading of the river. ground water is flowing through unconfined uniform 3m thick sand aquifer and discharging to river. two wells are located 50m apart and perpendicular to the flow and showing the water level difference of 1m. the hydraulic conductivity is 1*30^-3cm/s and the average contaminant concentration through out aquifer subjected to 200mg/L. the zone of flow and contamination is 100m long as measured to parallel to river.
