Two wells begin pumping at the same rate, Q=2000 m2/d, at the same time. They are
screened in a confined aquifer with K=20 m/d, thickness 40m, and storativity3D104.
There is an observation well located 100m from one well and 200m from the other.
What is the drawdown in the observation well after 5 days?
In the same aquifer, only one well begins pumping (assume initial drawdown is zero).
Initially its rate is 2000 m2/d, and after 5 days the pumping rate increases to 4000m2/d.
What is the drawdown in the observation well 100m away after 10 days?
