OUESTION $6$

$($a$)$ A flow net for flow around single row of sheet piles in a permeable soil is shown in fig$\mathrm{.}6.$ Given that $Kx=Kz=K=5x10-2m\frac{m}{s}$; determine

$($i$)$ how high $($ above the ground surface$)$ will the water rise, if measured by piezometers placed at points $A,B,C$ and $D?$

$(16$ marks$)$

$($ii$)$ What will be the rate of seepage through the flow channel II per unit length of the sheet pile?
