Question $6$

For the dam sections shown in the attached figure

$($a$)$ Draw a flow net for each dam

$($b$)$ Compute the flow underneath each dam per meter of the dam in a year if the permeability coefficient is $3\mathrm{.}5{10}^{-4}c\frac{m}{sec}.$

$($c$)$ For dam I only find the following at a depth of $6\mathrm{.}75$ m at the downstream end of the dam

$($i$.)$ Pore water pressure

$($ii$.)$ Piezometric head

$($iii$.)$ Superficial velocity

$($iv$.)$ Actual velocity if suil parisity $=0,33$

$($v$.)$ Seepage force per unit volume $($seepage pressure$)$
