Two pumping wells, W$1$ and W$2,$ are located at coordinates $(10\mathrm{.}0m,5\mathrm{.}0m)$ and $(60m,20m),$ respectively, in a confined aquifer, and are pumping at constant rates of $2\mathrm{.}0\frac{m^3}{s}$ and $1\mathrm{.}5\frac{m^3}{s},$ respectively. The following steady state drawdowns were observed at several observation wells in the aquifer as indicated below.
