#4: A confined aquifer is located between two rivers (River 1 and River 2), as shown. You are the engineer in charge who will make a decision to determine the best location (A, B or C) for a well to be dug. One suggestion is to have a well at a location where its head reaches the surface. This will save you installing a pump (capital cost) and operating it (subsequent operation and maintenance costs). To solve this problem, assume a steady state condition, determine the head profile in the aquifer between the two rivers and the direction of the flux. Once a decision is reached, explain your technical reasoning behind your decision
