$2.$ A well in a $20\mathrm{.}0-\backslash (\backslash$mathrm$\{$ft$\}-\backslash$mathrm$\{$thick$\}\backslash )$ unconfined sandy aquifer is pumped at a rate of $\backslash (80\mathrm{.}0\backslash$mathrm$\{$ft$\}^\{3\}/\backslash$mathrm$\{$min$\}\backslash ).$ An impermeable clay underlies the sand. Drawdown is measured at an observation well $124$ ft away from the pumping well and is shown in table P$5\mathrm{.}2$ and Figure P$5\mathrm{.}2.$ Estimate the specific yield, specific storage, and hydraulic conductivity. Show the plotted data, the overlays of the Theis curve, and clearly show the match points on the plot.
