The water$-$surface elevations of rivers located $375$ ft apart differ by $0\mathrm{.}5$ ft $.$ The

elevation of the lower water surface is $4\mathrm{.}5$ ft $.$

For a steady$-$state discharge of $40$ gals$/$day$/$ft$,$ compute the hydraulic

conductivity of the unconfined aquifer $(1$ gal$=0\mathrm{.}133681$ft$^(3)).$

Compute the water table elevation at $100,200,$ and $300$ ft from the first

water body.

Estimate the new discharge at both rivers after a long precipitation

event of $10$mm$/$h$.$
