Figure $2$ shows the flow nets for seepage beneath a concrete weir. Please answer the following

questions assuming the following soil properties for the $64-$foot$-$deep soil layer with $k=3\mathrm{.}3{10}^{-7}$

$f\frac{t}{sec,G_s}=2\mathrm{.}7,$ and ${}_t=120lbs\frac{.}{f}{t}^3$

a$.$ Number of equi$-$potential drops.

b$.$ Number of flow paths.

c$.$ Calculate the shape factor $(\frac{N_f}{N_d})$

d$.$ Seepage loss per unit length

e$.$ Maximum upward hydraulic gradient

f$.$ Possibility of boiling

g$.$ Pore pressures at points A

h$.$ Uplift pressure on the dam
