Fältarbetet följde SGF:s riktlinjer för slugtest. En bailer används för att dra en slug av vatten ur grundvattenröret. Vattennivån i röret mäts med ett piplod vid 15 s, 30 s, 1 min, 2 min, 5 min, 10 min, 15 min, 30 min och 60 min medan vattennivån återhämtar sig. Fem rör i området mättes, rör 16T04, 16T06, 16T08, 16T11, och 16T12.

Schematics of slug test in a monitoring well that is fully screened across a confined aquifer. Slug test is initiated at t = 0; figure not to scale. (From Butler, J.J. [1997] The design, performance, and analysis of slug tests. Lewis Publishers, Boca Raton, Fla.)

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 Tutorial 4: Slug Test Analysis 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). What is a Slug Test? • One well field test for determining hydraulic conductivity (K) • Entails: –“Instantaneously” adding or removing a slug of water in a well and monitoring water level recovery (head vs. time) – Substitute water level vs.

A considerable body of data has been amassed that indicates that the K estimate from a pumping test is, on average, considerably larger than the estimate obtained from a series of slug tests in the same formation.

Slug test response at GEMS well 0-2ß We have developed a general slug test model based on the Navier-Stokes equation, nonlinear frictional loss, non-Darcian flow, and acceleration effects that explains the features of high-permeability field data mentioned above. We al•o show how radius changes in the well bore will effect the model Several spreadsheets have been developed for the analysis of aquifer-test and slug-test data. Each spreadsheet incorporates analytical solution(s) of the partial differential equation for ground-water flow to a well for a specific type of condition or aquifer. A slug test is a particular type of aquifer test where water is quickly added or removed from a groundwater well, and the change in hydraulic head is monitored through time, to determine the near-well aquifer characteristics. 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. From these data, an estimate of hydraulic conduc-tivity can be calculated using appropriate analytical methods (for example, Ferris and Knowles, 1963).

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).

TEST BALLE CALIBRE 12 ( SLUG TEST 12 GAUGE) A slug test is a particular type of aquifer test where water is quickly added or removed from a groundwater well, and the change in hydraulic head is monitored through time, to determine the near-well aquifer characteristics. A slug testis a controlled field experiment performed by groundwater hydrologists to estimate the hydraulic properties of aquifers and aquitards in which the water level in a control well is caused to change suddenly (rise or fall) and the subsequent water-level response (displacement or change from static) is measured through time in the control well and one or more surrounding observation wells. 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 Tutorial 4: Slug Test Analysis During a slug test, a slug of known volume is lowered instantaneously into the well.
