Use the diagram of the unconfined (water-table) aquifer on the next page for the following questions....
For an unconfined aquifer with uniform recharge problem, the initial water table is 10 meters above the confining layer. Given recharge rate from rainfall 50 cm/year, pumping rate 1000 m^3 /day, aquifer hydraulic conductivity 10 m/day, calculate the effective radius and calculate steady-state groundwater head at 100 meters away from the pumping well.

An unconfined aquifer has an initial thickness of 15.80 m. The initial water table is horizontal and located 4.7 m below the ground surface. A 15-cm diameter well is driven to the bottom of the aquifer and pumped at 3000 Lpm until steady state conditions are achieved. At this time the drawdown at the well is 4.35 m and the drawdown in an observation well located 850 m away is 0.12 m. (a) Make a sketch that defines the problem....
