    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...

    An unconfined aquifer has an initial thickness of 15.80 m. The initial water table is horizontal and located 4.7 m below the ground surface. A 15-cm diameter well is driven to the bottom of the aquifer and pumped at 3000 Lpm until steady state conditions are achieved. At this time the drawdown at the well is 4.35 m and the drawdown in an observation well located 850 m away is 0.12 m. (a) Make a sketch that defines the problem....

    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 engineer has been asked to investigate illegal pumping of groundwater from an unconfined aquifer. The maximum withdrawal rate for the well has been set by the State Water Resources Board at 30,000 ft/day. The water table far from the well is 20 f below the surface. The depth to the confining bed is 50 ft. Two observation wells have been installed near the pumping well to assess the groundwater withdrawal rate. The first well is located 100 ft from...

    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,...

    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 10 inch diameter well is drilled to the bottom of an unconfined aquifer. The water table is originally 500 ft above the bottom of the aquifer. If 100 gal/min is pumped from the well, the equilibrium depth of the water in the well is 224 ft and the radius of influence is 1000 ft. (1) Determine the transmissivity T of the aquifer and (2). How much drawdown should be expected at a distance of 300 ft from the well?

    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...

    3) If the steady state pumping rate of an artesian aquifer, 155,000,000 gallons per year are being pumped by a fully penetrating well, a. What is the hydraulic conductivity if the aquifer is 166 feet thick and composed of medium sand? The drawdown at an observation well 48 feet away is 9 feet; in a second observation well 490 feet away it is 1.1 feet. b. If you have another observation well, between these two wells, 250 feet away from...
