The Theis equations are based on the assumption that the water is released from storage in the aquifer in immediate response to the decline in the water table. In unconfined aquifers, gravity drainage may not be immediate, particularly in fine grained formations and with stratifications of slow yielding materials. When a well is pumped in […]

In this article we will discuss about:- 1. Well Flow near Aquifer Boundaries—Image Wells 2. Method of Images 3. Method of Images for Particular Cases. Well Flow near Aquifer Boundaries—Image Wells: When a well is located close to a barrier (impermeable) or recharge boundary, marked deviations from a radial flow system occur. Solutions in such […]
