WIDE

Well Interface & Drawdown Evaluations

Version 1.2.0-1 - August 2004

WIDE, Well Interference and Draw-down Evaluation is developed to demonstrate the response of four major types of aquifers, (1) confined, (2) semi confined with storage, (3) semi confined without storage and (4) unconfined aquifers to groundwater pumping from a single or multiple wells at constant or varying pumping rates. WIDE is based on analytical solutions developed by Theis (1935), Hantush and Jacob (1954), and Neuman (1972), and the principle of super position of solutions. The principle of super position allows the analytical solutions to solve for pumping from several wells, or pumping from a single well at varying discharge rate, or to estimate the rate of recovery, or a combination of any of these.

The intended audiences of this tool are regional hydrogeologists, groundwater users and students in groundwater hydrology. WIDE should be used for demonstration and educational purposes only.
