Problem $1(10$ points$/10$ minutes$)$

A sandy$-$gravel unconfined aquifer $(1)$ is separated from a silty$-$clay confined aquifer $(3)$ by a

confining bed $(2).$ The water rises $6m$ in a piesometer screened just below the confining bed.

What is the elevation head $(z,$ pressure head $(h_p),$ and total hydraulic head $(h_r)$ of the

groundwater located at the points A$,$ B$,$ C and D$?$ Fill in the table.

confining

Which direction is groundwater flowing?

Based on the total hydraulic head values at points A$,$ B and D$,$ discuss your results.
