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 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.

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 permeability pumping test was carried out in unconfined aquifer with the piezometric level before pumping is 2.18m below the ground surface. The first permeable layer has a thickness of 5.7m measured from the ground surface and the unconfined aquifer is 7.0m deep until reaches the aquiclude at the bottom. At a steady pumping rate of 15.6m^3/hr the drawdown in the observation wells were respectively equal to 1.62m and 0.47m. The distance of the observation wells from the center of the test well were 15m and 32m respectively. If the hydraulic gradient is 0.0092 determine the seepage velocity at 0.25 void ratio?
