Two wells are located on a confined aquifer. The aquifer transmissivity is $10\frac{m^2}{m}in$ and the storage coefficient is $1{10}^{-4}.$ Well $1$ is located at $(x,y)=(10,200)$ and well $2$ is located at $(300,40).$

a $)$ Assume well $1$ is pumping alone with following pumping pattern:

$\backslash$table$[[$Time $($min$),$Q$],[0-1000,70],[1000-2000,10],[2000-3000,30],[3000,0]]$

b $)$ Assume well $2$ is pumping alone with following pumping pattern:

$\backslash$table$[[$Time $(min),$Q$],[0-800,60],[800-1500,100],[1500-3000,75],[3000,0]]$

Using the Jacob approximation for the Theis solution, plot the drawdown using time interval of $20$ over a total time of $6000$ at $(20,20)$
