Question 7
A well is pumped from a confined aquifer at a constant rate of 1000 gallons per minute (gpm). The following data were collected during the pumping
test:
.
Distance from the well to the observation well (r) = 150 feet
Differential drawdown (Ah) in the observation well at this distance = 2.5 feet
Aquifer properties:
Transmissivity (T) = 25,000 gpd/ft
• Storativity (S)- 0.0005 (dimensionless)
Pumping time (t) = 5 hours
Watch your units !!
Using the above information, calculate the drawdown (h) in feet in the observation well at a distance of 150 feet after 5 hours of pumping. (Use the
powerpoint slides for approximations for the well function W(u).
