Given:

Permeability, $k=40{10}^{-4}c\frac{m}{s}$

Saturated unit weight of the soil $=20k\frac{N}{m^3}$

Other information shown in the Figure E$3-3$

Determine the following:

$($a$)$ Quantity of Discharge $(15$ pts $)$

$($b$)$ Total vertical stress at Points $B$ and $D(15pts)$

$($c$)$ Pore$-$water pressure at Points B and D $(10)$

$($d$)$ Effective vertical stress at points B and D $(10$ pts$)$
