I was wondering if I could get help with parts b & c

2. In this problem we will consider groundwater flow in an unconfined aquifer that lies between two parallel canals that are connected to it as shown below h₁=10m K=1m/day h₂= 1 m 2000 m i. An equation for the hydraulic head in the unconfined aquifer between the two canals. ii. An estimate of the flow rate Q of water per unit (meter) length along the canals from the left to the right canal. b. A farmer places a well at x=1000m (at the center of the two canals). If the radius of influence of the well is 10km, what is the maximum possible rate of pumping that she could sustain? Think about this - it is a simple calculation c. The farmer actually places a well with an effective radius of 1m that goes all the way to the bottom of the aquifer. She will pump this well at 1m³/day. After initial testing and letting the pump run for several days, she notices that the water level adjacent to the well is no longer dropping, but is stable with a drop of 0.1 m from the original water level (which you computed in part a. above). What is your estimate of the water level at x=990 m and x=1010m in line with the well? Do you think your answer would be different if you had to consider the canals directly in solving this problem?
