Under recharge boundary conditions, water level in the observation well will drawdown initially under the influence of the production well only. When the cone of depression spreads to the recharge boundary, the time-rate of drawdown will change, due to the influence of the image well. The time-rate of drawdown will thereafter continually decrease till eventually […]

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 […]
How to Measure Well Losses? | Geography
Article shared by :
The ultimate drawdown in a well measured at the designed rate Q of continuous pumping for a given period is different from the theoretical drawdown due to well losses. The total drawdown sw is made up of: (i) Head loss resulting from laminar flow in the formation (formation loss), (ii) Head loss resulting from the […]
