Q-26: A 0.5 m diameter well fully penetrates an unconfined aquifer whose bottom is 150 m below the undisturbed groundwater table. The water is pumped out from the well at a constant rate of 0.1 m³/s. After equilibrium is reached, the drawdown observed in two observation wells at radial distances of 10 m and 50m are respectively 10 m and 5 m. Determine (i) The coefficient of permeability (in m/s) (ii) The drawdown in the well (in m)
Q3. A 200 mm diameter well which fully penetrating a confined aquifer of thickness 25 m is pumped at a constant rate of 2000 m3/day. The steady state drawdown in the well is 8 m and the drawdown in a piezometer 100 m from the well is 1.4 m.(a) Ignoring well losses, calculate the transmissivity of the aquifer, the hydraulic conductivity of the aquifer material and the radius of influence of the well.(b) Repeat the calculation for an unconfined aquifer with saturated thickness 25 m
The thickness of a horizontal, confined, homogeneous, isotropic aquifer of infinite areal extent is 30m. A well fully penetrating the aquifer was continuously pumped at a constant rate of 0.1 m³/s for a period of 1 day. The drawdowns given in the table below were observed in a fully penetrating well 90 m from the pumping well. Compute the transmissivity and the storativity by using: a) the Theis method of log-log matching. b) the Cooper-Jacob method of semi-log plotting. [For Part a), you have to first use attached Table to plot the values of W(u) versus 1/u on a log-log graph in the range of 10-9
A confined aquifer has a transmissivity T = 200 ft2/day (18.6 m2/day) and a storativity S = 0.0002. A fully penetrating well begins pumping in this aquifer at a rate of 1500ft3/day (42.5m3/day). Using the Theis solution predict the drawdown h0 h at a radius of r = 100 ft (30.5 m) at the following elapsed times: 10 minutes, 1 hour, 5 hours, and 24 hours. *tip* Spreadsheet software could help you do these repeated calculations.
An unconfined aquifer is 10 m thick and is being pumped so that one observation well placed at a distance 76 m shows a drawdown of 0.5 m. On the opposite side of the extraction well is another observation well 100 m from the extraction well, shows a drawdown of 0.3 m. Assume the coefficient of permeability of 50 m/day. a.) What is the discharge f the extraction well? b.) Suppose the well at 100 m from the extraction well is now pumped. Show with a sketch what this will do to the drawdown. c.) Suppose the aquifer sits on an aquaclude that has a slope of 1/100. Show with a sketch what this will do to the drawdown.

In using a permeameter, it is sometimes convenient to make a “falling -head” test. The horizontal tube is 1 m long and 10 cm in diameter and is filled with sample material. During a test, the upstream head h₁ falls from 200 to 180 cm in 4 hr, while h₂ is held constant at 15 cm. The diameter of the vertical tube in which h₁ is measured is 40 cm. What is the indicated average hydraulic conductivity? Estimate the range between maximum and minimum values of hydraulic conductivity.

A 30 cm well penetrates 45 m below the static water table. After a long period of pumping at a rate of 1200 lpm, the drawdown in the wells 20 m and 45 m from the pumped well is found to be 3.8 and 2.4 m respectively. Determine the transmissivity (-K*aquifer thickness) of the aquifer. What is the drawdown in the pumped well? [Hint: Use water table depth as aquifer thickness in the case of unconfined aquifer]
