(please add answer and units to answer box, show work, and/or send email with pdf/image showing work) A well in a confined aquifer was pumped at a rate of 200 ft°/min for 240 minutes. Time-drawdown data for a well 800 feet away were plotted on log-log paper an matched to a Theis type curve. The match point was W(u)=1, 1/u=1, s=0.89 feet, and t=4.1 minutes. The aquifer is 150 feet thick. What is the hydraulic conductivity of this aquifer? What is the storativity (also known as storage coefficient) of the aquifer?
A confined aquifer has a transmissivity, T, of 30 m2/day and a storage coefficient, S, of 0.0008. A production well of radius, r, 0.2 m is pumped at 200 litres/min for 4 days and shut off. Calculate the maximum drawdown and the drawdown 10 days after the start of pumping at the well. Note: Calculate the result rounded to the second digit after the decimal point.
