Assume that the stated drawdowns are measured from the static phreatic surface. Also assume that the drawdown curve does not intersect the confined aquifer. Repeat problem if the aquifer is confined with a thickness of 50 ft.
problem
An unconfined aquifer has a static thickness of 200 ft. A 12-in.-diameter well is pumped at a constant rate of 750 gpm. The coefficient of permeability is 410 gpd/ft2 and the radius of influence of the well at that discharge is 3500 ft. Determine and plot the drawdown curve for the well.
