The drawdown doserved at a confined aquifer well after pumping it during 1400 minutes at a flow rate of 500 gal/min is 20.39 ft. The drawdowns observed at the same time at two observation wells located at 10 ft and 100 ft from the pumped well are 20 and 19.7 ft, respectively. Find the transmissivity of the aquifer and the well radius. Answ: T-8.8x105 gpd/ft, r-0.5 ft. 3.

Problem 24 A well is screened in a completely confined aquifer is to be pumped at a rate of 165,000 ft/d for 30 days. If the aquifer transmissivity is 5320 ft/d and the storativity is 0.0007, what is the drawdown at 50, 150, 250, 500, 1000, 3000, 5000, and 10,000 ft Problem 25 If the aquifer in problem 24 is not completely confined, but overlain by a 8.0 ft leaky confining layer with a vertical hydraulic conductivity of 0.024 ft/d...

The following values for a confined aquifer are measured from the ground surface: depth to piezometric level before pumping = 25 ft depth to top of aquifer = 75 ft depth to bottom of aquifer = 125 ft. A 24-inch diameter well is driven to the bottom of the aquifer an pumped at 500 gpm until steady state conditions are attained. The drawdown at an observation well 50 ft from the pumping well is 10 ft and the drawdown at...

An aquifer test with a constant pumping rate of 200 gpm was conducted in a confined aquifer with a saturated thickness of 12 m. Head measurements in an observation well located 76.2 m (250 ft) from the pumping well yields the following plot.

Examples Example 3: A well of diameter 0.5 m fully penetrates a confined aquifer. The well is pumped for a test at 0.833 m3/min and the values of the drawdown at an observation well 20 m from the pumped well are measured at different times. The results are tabulated below.

1. (2 points) A well in a uniform, homogeneous, isotropic confined aquifer is pumped at a rate of 815 L/min. After 3 days it looks as if the water levels have stabilized in observation wells at distances of 20 m and 200 m from the pumping well. The drawdown in the well at 20 m is 6.5 m and the drawdown in the well at 200 m is 3.5 m. a) Use the Thiem solution to determine the aquifer transmissivity....
