 Downward seepage occurs from a
shallow pond to a water table. A conservative traces is introduced at
point A. Calculate the location of tracer appearance at the water table
and the time it takes. Neglect dispersion, diffusion and assume
subsurface fully saturated.

 Consider a pumping well in an unconfined aquifer receiving a recharge
at a rate W. The saturated thickness beyond the radius of influence of
the well (R) is H0 examine drawdown distribution and value of R.
