Stallman as described by Lohman (1972), pp. 41-43. Stallman's
equation for discharge from a confined aquifer in a channel drain
with constant drawdown is as follows:
Q = 2s ST
Tl t
Where: Q = discharge from both sides of the drain per
unit length of drain, in gallons per day.
s = drawdown of piezometric head at time zero,
constant in feet.
t = time since discharge began, in days.
S = storage coefficient, unitless.
T = transmissivity, in cubic feet per day per
foot.
