For the flow net shown in figure $(4)$:

Find the pore water pressure at point $$A$$

Hydraulic gradient at point $$A$$

Compute the seepage quantity per meter of the wear per day for k $=4$ x $10-2$ cm$/$s

Check the factor of safety against quick condition if G$=2\mathrm{.}65,$ e$=1\mathrm{.}05.$

What surcharge weight on the downstream that will provide a safety factor of $6$

against quick condition at the exit?
