Bouwer and Rice Slug-Test Method

Bouwer and Rice (1976) developed a method of determining the hydraulic conductivity of an unconfined aquifer.  This method can be used for both fully and partially penetrating wells.  While originally developed for unconfined aquifers, it has been found that it can also be used in confined aquifers, provided the top of the well screen is some distance below the bottom of the upper confining layer.

The equations used to determine the hydraulic conductivity with the Bouwer and Rice method are as follows:

There are many programs available for analyzing slug tests results, including Single Well Solutions

Single Well Solution

Single Well Solutions is a powerful Windows software product that contains a collection of the most popular analytical solutions from "Analysis and Evaluation of Pumping Test Date," by G.P. Kruseman and N.A. deRidder, second edition (1990), for determining aquifer hydraulic conductivity and pumping well efficiency from single well test data


Wide selection of analysis methods

Single Well Solutions is capable of analyzing single well test data with a variety of methods.  These methods include:

Slug Tests:

  • Bouwer and Rice (1976)

  • Cooper et al. (1967)

Constant Discharge

  • Hurr and Worthington (1981)

  • Hantush (1964)

Variable Discharge

  • Bisroy and Summers (1980) (both Intermittent and Uninterrupted Pumping)

Step Drawdown

  • Hantush and Bierschenk (1964)

Constant Discharge Recovery

  • Theis (1935)
