Question $16$: A well is drilled into an unconfined aquifer and is pumped

at a constant rate, the aquifer has reached steady state. The hydraulic

conductivity of the aquifer is $K=5\frac{m}{?}$ day. The static water table $($before

pumping$)$ is at a height of $h_0=30m$ above the base of the aquifer. The

radius of the well is $r_w=0\mathrm{.}3m,$ and the distance to an observation well

is $r_o=60m.$ The water table in the observation well during pumping is

at a height of $h(r)=28m$ above the base of the aquifer. The radius of

influence $(R^{\text{'}})$ of the pumping well is $100$ m $.$
