PROBLEM A pumping test was conducted in a confined aquifer with a constant pumping rate of 1000 m³/day. Three observation wells were placed at radial distances equal to 30 m, 90 m, and 215 m, respectively. The observed drawdowns at these three observation wells are provided in a separate file. Estimate the aquifer transmissivity T and storage coefficient S using: a. Theis method based on data from observation well #1 (radius= 30 m) only; b. Theis method based on data from all three observation wells; c. Jacob's method (time-drawdown) based on data from observation well #1 (radius= 30 m); d. Jacob's method (distance-drawdown) based on data from all three observation wells at time = 140 min.
