Figure $(1)$ shows a weir section, constructed on a clayey sand layer where the coefficient of permeability is $\backslash (1\mathrm{.}5\backslash$times $10^\{-4\}\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash ).$ For this question, you are required to:

$1)$ Draw the flow net for seepage.

$2)$ Determine the quantity of seepage $($flow rate per meter$)$ in $\backslash (\backslash$mathrm$\{$m$\}^\{3\}/\backslash$mathrm$\{$s$\}\backslash )$ per meter under the dam.

$3)$ Plot the distribution of uplift pressure in $\backslash ($ k P a $\backslash )$ on the base of the dam.

$4)$ Determine the uplift force in $\backslash ($ k N $\backslash )$ per unit length of the dam.

$5)$ Plot pore pressure $($ kPa $)$ diagrams along A$-$D and B$-$C lines. Flow net and quality of flow net
