Type curves for selected problems of flow to wells in confined aquifers

This report presents type curves and related material for
11 conditions of flow to wells m confined aquifers. These
solutions, compiled from hydrologic literature, span an
interval of time from Theis (1935) to Papadopulos, Bredehoeft,
and Cooper (1973). Solutions are presented for
constant discharge, constant drawdown, and variable discharge
for pumping wells that fully penetrate leaky and
nonleaky aquifers. Solutions for wells that partially penetrate
leaky and nonleaky aquifers are included. Also, solutions
are included for the effect of finite well radius and
the sudden injection of a volume of water for nonleaky
aquifers. Each problem includes the partial differential
equation, boundary and initial conditions, and solutions.
Programs in FORTRAN for calculating additional function
values are included for most of the solutions.
