Estimate the volumetric flowrate through a compacted clay liner at a landfill measuring $4\mathrm{.}5$ ha$.$ The liner thickness is $0\mathrm{.}61-m(2-$ft$)$ and the saturated hydraulic conductivity is $1\mathrm{.}0{10}^{-7}c\frac{m}{s}.$ Assume $0\mathrm{.}20-m(7\mathrm{.}87-$inch$)$ water ponded on the liner.

$5\mathrm{.}15\frac{m^3}{d}ay$

$8\mathrm{.}45\frac{m^3}{d}ay$

$10\mathrm{.}05\frac{m^3}{?}$ day

$6\mathrm{.}95\frac{m^3}{d}ay$
