Moench-Prickett Solution for Confined Aquifers Undergoing Unconfined Conversion

Description

A mathematical solution by Moench and Prickett (1972) is useful for determining the hydraulic properties (transmissivity, confined storativity and specific yield) of confined aquifers undergoing conversion to unconfined conditions. Analysis involves matching the Moench-Prickett solution to water-level displacement data collected during a pumping test.

AQTESOLV for Windows provides visual and automatic methods for matching the Moench-Prickett solution to pumping test data. This easy-to-use and intuitive software promotes rapid and accurate determination of aquifer properties.

Assumptions

The following assumptions apply to the use of the Moench-Prickett solution:

	aquifer has infinite areal extent
	aquifer is homogeneous, isotropic and of uniform thickness
	pumping well is fully penetrating
	flow to pumping well is horizontal
	pumping rate is constant
	aquifer is confined with conversion to unconfined conditions
	flow is unsteady
	water is released instantaneously from storage with decline of hydraulic head
	diameter of pumping well is very small so that storage in the well can be neglected

Solution Options

AQTESOLV for Windows provides the following options for the Moench-Prickett solution:

multiple observation wells
