A well with a diameter of 18 in. penetrates an unconfined aquifer that is 100ft thick. Two observation well are located at 100 ft and 235 ft from the well, and the measured drawdownsare 22.2ft and 21ft, respectively. Flow is steady and the hydraulic conductivity is 1400 gpd/ft^2. What is the steady-state rate of discharge from the well?

A 0.34 m diameter well fully penetrates an unconfined aquifer which is 33.2 m thick. The drawdown at the pumping well is 1.34 m and the permeability of the gravel aquifer is 4.32 * 10-3 m/s. If the flow is steady-state and the discharge is 422.3 lt/min, a- find the drawdown at the site 132.4 m from the center of the pumping well, b- determine the radius of influence ‘r∞’ of this well under that discharge.
A well pumping test was carried out to determine the bulk permeability of a confined aquifer. The aquifer was overlain by a clay layer 4m thick, the depth of the aquifer was 20m, and the initial piezometric level in the aquifer was 2m below ground level. After a period of pumping when steady state conditions had been reached, the following observations were made:pumped flowrate q=1.637 li/swell radius=0.1mdrawdown just outside well = 2mdrawdown in piezometer at 100m distance from well = 0.2m.Determine the bulk permeability of the aquifer in m/s . Use the format for your answer 1.111 x 10^(-4).
The static level of water table in an unconfined aquifer was 30 m above the underlying impermeablestratum. A 150 mm diameter well, penetrating the aquifer to its full depth, was pumped at the rate of20 liters per second. After several weeks of pumping, the drawdown in observation wells 20 m and 50m from the well were 3.5 m and 2 m respectively, and the observed drawdowns were increasing veryslowly (B.Sc., DU, 2012).a) Assuming equilibrium conditions, estimate the hydraulic conductivity and transmissivity of theaquifer.b) Estimate the drawdown just outside the pumped well.c) What will be the yield of a 300 mm diameter well which will produce the same drawdowns justoutside the well and at the 50 m distance observation well in (2)? What would be the drawdown at anearer observation well?
A 1m diametee well penetrates vertically through a confined aquifer 30m thick. When the well is pumped at 113 m^3/hr , the drawdown in a well 15m away is 1.8m, in another well 50m away, it is 0.50m. What is the approximate drawdown in the pumped well?
A 12 inch diameter well was installed in an unconfined aquifer consisting of a 60 foot thick layer of sand. The water table was 15 feet below the ground surface before pumping of the well began. The well was then pumped at a rate of 30 gallons per minute and the water level in the well dropped to 45 feet below the ground surface after a steady-state condition was reached. The radius of well influence is 4000 feet. a) Calculate the permeability of the sand b) Compute and plot the drawdown surface
A well pumps at a steady rate of 70gallons/minute (265L/min). It is located 50ft (15.2m) from a lakeshore that is roughly straight. The well is installed in a 6 inch (15.2cm) diameter hole. The well screen and the lake penetrate the same confined aquifer. While pumping, the head in the well is 6.5ft (1.98m) lower than the head in the lake. Estimate the average transmissivity of the aquifer near the well and report your answer inft2/day or m2/day. Assume that without the well pumping, the head at the well is essentially the same as the head in the lake. Be careful to use consistent units in your calculations.

A concrete dam retains water to a height of 9 m. It has rows of sheet piling at both heeland toe which extend half way down to an impervious stratum. From a flow net sketchedon a transformed section, it is found that there are four flow channels and sixteen headdrops. The average horizontal and vertical permeabilities of the soil are 6 × 10^–3 mm/sand 2 × 10^–3 mm/s, respectively. What is the seepage in cubic meter per day, if the lengthof the dam is 150 meters?
A pumping test was made in a sand layer extending to a depth of 16m. The initial groundwater table was located 2m below the ground surface. Observation wells were sighted at distances 4m and 9.5m from the pumping well. Using a discharge of 0.4 cubic meters per hour, a steady level is attained at the pumping well. The measured drawdowns at the two observation wells are 2m and 0.25m respectively. Solve the hydraulic head 5m from the pumping well.
