Problem $2-11$

Two piezometers are located $1000$ ft apart with the bottom located at depths of $50$ ft and $350$ ft respectively in a $400$ ft thick unconfined aquifer. The depth to the water table is $50$ ft in the deeper piezometer and $40$ ft in the shallow one. Assume that hydraulic conductivity is $0\mathrm{.}0002\frac{ft}{sec}.$

A$)$ Use the Dupuit equation to calculate the height of the water table midwaybetween the piezometers.

B$)$find the quantity of seepage through a section $25$ ft wide

C$)$ find the average liner velocity in the deeper well
