Consider seepage occuring in the two soil layers within the U$-$tube $(0\mathrm{.}5$ m x $0\mathrm{.}5$m$)$ as shown in the figure below. The hydraulic conductivities of the soils are as below:

k$1=1\mathrm{.}0*10^-2$

k$2=2\mathrm{.}5*10^-3$

a$.$ Determine the flow rate, q$,$ through the two layered system.

b$.$ Determine the hydraulic gradient in each soil layer.

c$.$ Determine the total head $($Hc$)$ and pressure head $($Hp$)$ at point C
