Bouwer-Rice Slug Test Solution for Unconfined Aquifers

Description

A mathematical solution by Bouwer and Rice (1976) is useful for determining the hydraulic conductivity of unconfined and confined aquifers. Analysis involves matching a straight-line solution to water-level displacement data collected during a slug test. Bouwer (1989) points out the applicability of this solution for slug tests in confined as well as unconfined aquifers.

AQTESOLV for Windows provides visual and automatic methods for matching the Bouwer-Rice solution to slug 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 Bouwer-Rice solution:

	aquifer has infinite areal extent
	aquifer is homogeneous and of uniform thickness
	aquifer potentiometric surface is initially horizontal
	test well is fully or partially penetrating
	a volume of water, V, is injected or discharged from the well instantaneously
	aquifer is confined or unconfined
	flow is steady

Solution Options

AQTESOLV for Windows provides the following options for the Bouwer-Rice solution:

	partially penetrating wells
	correction for gravel pack porosity
	hydraulic conductivity anisotropy
