Question 5: (25 marks) A fully penetrating pumping well is located in a confined aquifer that can be considered to have an infinite extent in all directions. There is no recharge to the aquifer and no other pumping wells in the area. There are two observation wells located at 100 and 500 m, respectively, from the pumping wells. The aquifer and the pumping well have the following properties: Depth to top of aquifer: 50 m Aquifer thickness: 5 m Aquifer...

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....

A well is constructed in a confined aquifer. The aquifer has a uniform thickness of 50 ft overlain by a aquitard and the bottom is 115 ft below ground surface (bgs). A pumping test weas used to determine the hydraulic conductivity of the aquifer. The initial piezometric (potentiometric) surface of the confined aquifer was 49 ft bgs at the pumping well and the observation wells. After water was pumped at a rate of 0.46 cu ft/sec for several days, the...

a. A well 50 cm in diameter penetrates 33 m below the static water table. After a long period of pumping at a rate of 80 m/h, the drawdowns in two observation wells A and B, 18 and 45 m from the pumped well, were found to be 1.8 and 1.1 m respectively. Determine . the hydraulic conductivity of the aquifer (in m/d) . the expected drawdown in the pumped well • the radius of influence of the pumped well,...

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...

A well is pumping near a barrier boundary at a rate of 0.05 m3/s
from a confined aquifer 20 m thick. The hydraulic conductivity of
the aquifer is 5 x 10-4 m/s, and its storativity is 4 x 10-5.
Determine the drawdown in the observation well after 30 hours of
continuous pumping. What is the fraction of the drawdown
attributable to the barrier boundary?

1) In a leaky confined aquifer, estimate how far from a well pumping at 175 m3/day a steady state drawdown of 0.4 m will be observed. Assume the aquifer is 10 m thick with a horizontal hydraulic conductivity of 7 m/day, the K' is 1 m/day and the b' is 1 m thick, the storativity of the aquifer, S, is 0.02. 2) For the conditions in problem 1, estimate the drawdown at this location after 15 minutes. 3) At the...
