The artesian aquifer is 15 m thick with a piezometric surface 40 m above the bottom confining layer. The aquifer is a limestone. After 300 days of pumping, the drawdown at a nonpumping well 150 m from the pumping well is 1.5 m. The pumping well is 1 m in diameter. Assuming a typical hydraulic conductivity for limestone and a 1.5 m safety factor, determine the maximum allowable sustained pumping rate.

An unconfined aquifer is 25 m thick. Groundwater is being pumped out from a 0.10 m diameter fully penetrating well. The pumping rate is Qp=0.15 m3 /min. The aquifer is relatively sandy with a hydraulic conductivity of 8.2 m/d. Steady-state drawdown of 1.5 m is observed in a monitoring well 3 m away from the pumping well. Estimate (a) the drawdown 10 m away from the pumping well, (b) the drawdown in the pumping well.

A 10 inches diameter well is drilled to the bottom of an unconfined aquifer. The water table is originally 500 ft above the bottom of the aquifer whose hydraulic conductivity is known to be 0.25 ft /day. If 100 gal/min is pumped from the well, what will be the equilibrium depth of the water in the well if the radius of influence is 1000 ft? How much drawdown should be expected at a distance of 250 ft from the well?

A confined aquifer of thickness 35 m is pumped at a rate of 100 L/s from a well of radius 0.5 m. The recorded drawdowns in a monitoring well located 200 m from the pumping well are given in Table. 3.3. Use the steady-state approach to estimate the hydraulic conductivity and transmissivity, if it is assumed that the condition is reached equilibrium after 1-day of constant pumping. time (s) Drawdown (cm) 0 0 10 0.6 100 5 1000 60 10000...

. It is required to dewater a construction site 80 m by 80 m. The bottom of the construction will be 1.5 m below the initial water surface elevation of 90 m. Four pumping wells (radius of each well is 0.5 m) are to be used and placed at the site four corners. The confined aquifer transmissivity and storage coefficient are 1,600 m2/day and 0.16, respectively. The site needs to be ready for construction after one month of pumping. Determine...
