Regardless of whether a slug test is performed in a conventional (Figure 1a) or multilevel (Figure 1b) format, the pneumatic method [Prosser, 1981] is most appropriate for test initiation in highly permeable intervals (see Appendix A). Given the short duration of slug tests in highly permeable aquifers, a Pressure transducers are frequently used to monitor slug tests, and to collect a data set for height Z of water column versus time t. Direct application of the data to draw a velocity graph usually produces a wide scatter, thus limiting the usefulness of the velocity graph method.

Assumptions. The Hvorslev Solution assumes the following: • Unconfined or non-leaky confined aquifer of “apparently” infinite Here is a Bouwer and Rice graph showing exclusion of data points at the beginning and end of the test to allow a better fit of the line to the data. Super Slug provides extensive flexibility for fitting the line to data. The buttons on the bottom left and right corners of the screen exclude or include data from the analysis.

A slug test is a variation on the typical aquifer test where an instantaneous change (increase or decrease) is made, and the effects are observed in the same well. This is often used in geotechnical or engineering settings to get a quick estimate (minutes instead of days) of the aquifer properties immediately around the well. The USGS has published software for analysis of aquifer-test and slug-test data. Barlow and Moench (1999) recently published the FORTRAN program WTAQ, which is based on radial axisymmetric flow to a well under confined or unconfined conditions.

The primary advantages of using slug tests to estimate hydraulic conductivities This method was originally published in an article entitled "Slug Test Procedure to Evaluate Hydraulic Conductivity of an Aquifer Applicable to Fully or Partially Penetrating Wells in Unconfined Aquifers". Computer programs for aquifer evaluation by slug test and other methods are most commonly used to interpret the raw slug test data. Pressure transducers are frequently used to monitor slug tests, and to collect a data set for height Z of water column versus time t. Direct application of the data to draw a velocity graph usually produces a wide scatter, thus limiting the usefulness of the velocity graph method. This paper proposes to interpret the data set in five steps.

Confined aquifers, unsteady-state flow.

During a slug test the water level in a well is changed rapidly, and the rate of water-level response to that change is measured. THE SLUG TEST. INTRODUCTION: The hydraulic conductivity of an aquifer can be determined by a series of tests using a single piezometer.

A slug test also does not require disposal of large quantities of water. However, recognize that a slug test’s shorter time frame and limited stress on the system provides a measurement of hydraulic conductivity on a smaller scale than a pumping test. Depleted uranium is very dense; at 19,050 kg/m 3, it is 1.67 times as dense as lead, only slightly less dense than tungsten and gold, and 84% as dense as osmium or iridium, which are the densest known substances under standard (i.e., Earth-surface) pressures. obtained by the slug test, the grain size distribution, and the specific capacity test methods.
