Consider a water$-$saturated, homogeneous, isotropic, vertical cross section ABCDA with upper

boundary AB$,$ basal boundary DC$,$ left$-$hand boundary AD and right$-$hand boundary BC$.$ The cross$-$

section has a trapetzoidal shape. The elevations of the bottom points D and C are $0$m$,$ A is $100$m$,$ and

B is $130$ m$.$ The distance between D and C is $200$ m$.$ Let AD$,$ DC and BC be impermeable and let AB

represent a water table of constant slope $($on which the hydraulic head equals the elevation$).$ Draw a

quantitatively accurate flow net for this case. Label the equipotential lines with their correct h value
