Question

4. You have three wells, located (x,y)-(0,0), (15,20) and (10,10) and the respective head at each well is 15,140 and 85. All units are in meters. (A) Write an equation for the head distribution assuming an unconfined aquifer, given that you know heads at two locations. To do this, you need a solution to the 1-D unconfined GWFE where there is no recharge eener fraredlad krnhhr ) P pel (B) Based on the equation above, write a similar equation for the head distribution assuming a confined aquifer, given that you know heads at two locations. Do the derivation following the one for the unconfined aquifer above, but with a confined version of the GWFE 3 pts] (C) You obtain a fourth measurement at (x,y)=(55) where the head is approximately 50, Based on the first two parts, is the aquifer confined or unconfined? Why? [3 pts
