ABSTRACT
When a water supply production well in a uniformly porous nonleaky artesian aquifer is pumped, water is continuously withdrawn from storage within the aquifer to balance pumpage as the cone of depression progresses radially outward from the well. Mahdi Hantush presents equations for calculating drawdown distribution in a nonleaky artesian aquifer having a variable thickness which increases exponentially in the x-direction and is uniform in the y-direction. Kanwar, et al. presents equations for calculating drawdown distribution in a nonleaky artesian aquifer when a production well with a hemispherical bottom just penetrates the aquifer top. If the production well has a finite diameter and wellbore storage is appreciable, the discharge rate is the sum of the aquifer flow rate and the rate of wellbore storage depletion. Flow behavior in fractured rock aquifers differs from that in uniformly porous aquifers such as sand and gravel deposits. Flow in fractured rock aquifers is very complex and is the subject of much debate.
