A 1-m diameter well penetrates vertically through a confined aquifer 30 cm thick. When the well is pumped at 113 m³/hr, the drawdown in a well 15 m away is 1.8 m, in another well 50 m away, it is 0.5 m. What is the approximate head in the pumped well for steady state conditions and what is the approximate drawdown in the well? Also compute the transmissivity of the aquifer and the radius of influence of the pumping well. Take the initial piezometric level as 40 m above the datum.

A well of 20 cm diameter fully penetrates a confined aquifer. After a long period of pumping at a constant rate of 2720 litres/ minute, the observation of drawdown taken at 10 and 100 m distances from the centre of the well are found to be 3 m and 0.5 m respectively. The transmissivity of the aquifer is:

A 4-cell aquifer model is conceptualized in the figure below. River Cell 1 Cell 2 Cell 3 (a) Top view (b) Cross section Cell 4 Impervious boundary The width of the aquifer strip is 3.0 km; the length of each cell is 5 km. The recharge rates for the aquifer strip is 400 mm/yr, 300 mm/yr, 300 mm/yr, 200 mm/yr in Cells 1,2,3, and 4,respectively. The water level in the river is maintained at a constant elevation of 160 m above the horizontal impervious bottom. The hydraulic conductivity in Cells 1 and 2 is 3 m/d, while in Cells 3 and 4 it is 6 m/d. Using this conceptual model, determine: 1. Write the steady-flow balance equations to estimate average water levels in the four cells. 2. Solve these equations to determine the average elevations in the 4 cells without pumping. 3. Solve these equations when pumping takes place in Cells 2 and 3 at rates of 4×106 m3/yr and 7×106 m3/yr, respectively.

A tube-well of 20 cm of diameter fully penetrate a horizontal, homogeneous and isotropic confined aquifer of infinite horizontal extent. The aquifer is of 30 m uniform thickness. A steady pumping at the rate of 40 litres/s from the well for a long time results in a steady drawdown of 4 m at the well face. The subsurface flow to the well due to pumping is steady, horizontal and Darcian and the radius of influence of the well is 245 m. The hydraulic conductivity of the aquifer (in m/day, round off to integer) is

Yuri wants to determine the permeability of an aquifer. The aquifer has a test well 300-mm in diameter with two observation wells. A pumping test was conducted for 24 hours with the discharge being held constant at 5,896.3 m^3/day. The first one, 82.87 meters from the test well, has a draw-down of 0.86 meters. The second one, 44 meters from the test well, has a draw-down of 1.21 meters.The static water table penetrates the well to a depth of 28 meters. Determine the radius of influence of the aquifer in meters. Round off to three decimal places.
