We usually use the Method of Bouwer and Rice (1976) to obtain hydraulic conductivity from raw slug test data. This method was originally published in an article entitled "Slug Test Procedure to Evaluate Hydraulic Conductivity of an Aquifer Applicable to Fully or …

Oct 3, 1994 When the slug test is performed using an electronic data-logger and pressure transducer, all data will be stored internally or on computer 

2019-11-18 A slug test is based on instantaneously making the water level in the bore either rise or fall, and then recording the behavior of the water level versus time as the water returns to its original position. The Slug Test Method is one of a number of different methods that are used to evaluate the permeability (or hydraulic conductivity) of an aquifer. The procedure involves either adding or removi ng a measured quantity of water from a well rapidly, followed by making a rapid series of water-level measurements to assess the rate of water-level recovery (either rising-head or falling-head). Ett enkelt hydrauliskt test är enhålstest (på engelska: slugtest), som utförs genom att grundvattenytan i ett grundvattenrör höjs eller sänks hastigt och återhämtningen … During a slug test, a slug of known volume is lowered instantaneously into the well. This is equivalent to an instantaneous addition of water to the well, which results in a sudden rise in the water level in the well (also called a "falling head" test).

I forbindelse med projektets gennemførelse blev der til bestemmelse af den hydrauliske ledningsevne K [m/s], gennemført en række slugtests, der dannede grundlag for beregning af den hydrauliske ledningsevne i den øvre moræneler til 4,5 meter under terræn. 1.1 Teori "By using real-world slug test data during the webinar, I was able to see right away how Jim Butler's guidelines improve the efficiency and confidence in hydraulic conductivity test results. The presentation's clear graphics and on-site examples made this a practical learning experience, and I will certainly be able to implement these ideas both in the field and in analysis."

In addition, one spreadsheet was devel­ oped to predict drawdown in a confined aquifer based on the Theis equation. This spreadsheet is not designed to esti­ mate aquifer parameters. The Hvorslev (1951) method of slug test analysis addresses a variety of well and aquifer geometries, is easy to apply, and is widely used.

Slug Test Characterization Results for Multi-Test/Depth Intervals Conducted During the GWPD 17—Conducting an Instantaneous Change in Head (Slug) Test with a Mechanical Slug and Submersible Pressure Transducer VERSION: 2010.1 PURPOSE: To obtain data from which an estimate of hydraulic conductivity of an aquifer can be calculated. During a … Geoprobe Systems ® developed the GW1600 Pneumatic Slug Test Kit for use with Geoprobe ® brand groundwater sampling, profiling, and monitoring tools to conduct pneumatic slug tests in saturated formations of unconsolidated soils or sediments. The hydraulic conductivity test system provides high-quality data for accurate determination of formation hydraulic conductivity (K).

En person som utför ett slug-test i USA kommer att behöva följa både protokollet som upprättats av US EPA, det protokoll som har upprättats av statens  Provtagningsplan, fältarbete, undersökningar och förberedelser, instrumenthyra, resor mm (60 000 kr).

Slug-test data were collected from 12 wells at the Hillview Reservoir during August 2007 and from 25 wells at the reservoir and 1 monitoring well south of the reservoir in northern Bronx County in June 2012. Hydraulic conductivity values at the reservoir ranged from 0.0012 to 2 feet per day.

Indeed, the reliability of a slug test is less than a pumping test that, when it is possible to use, undoubtedly more accurately estimates perme-ability.

For example, plausible estimates of  help ed. steady Proc. With the slug test the hydraulic conductivity or transmissibility of an aquifer is determined from the rate of rise of the water level in a well  His slug test results also compared well to the constant-rate aquifer test. Could it be that the methods (Bouwer and Rice and Hvorslev) are correct for the wrong  However, smooth curves are exceptions in practice, thereby leading to a reexamination of the influence of S during a slug test. Three independent approaches  The wells can be partially penetrating and partially screened, perforated, or other: 'se open. The slug test can be based on quickly with- drawing a volume of water  Developed by Paul Santi (GE Dept, CSM) and computer science students.
