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 ChapterSlug, Packer, and Pressure Transient Testing. The tests involve recording the water level (pressure) response in a well to an instantaneous increase or lowering of water level 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. After the initial rapid change in water level, the water column Z varies versus time t within the A slug test involves inducing a rapid change in water level in a well. Alternatively, a small Slug tests assess the local value of hydraulic conductivity K in tested aquifers. time data and well geometry parameters into a mathematical model to solve for K. Why Determine K? A slug test involves the instantaneous injection or withdrawal of a volume or slug of water or solid cylinder of known volume. Slug tests are a commonly used method to determine the hydraulic conductivity of strata near a borehole. In a slug test, a small volume (or slug) of water is suddenly removed from a well, after which the rate of rise of the water level in the well is measured. of water is VERSIONPURPOSE: To obtain data from which an estimate of hydraulic conductivity of an aquifer can be calculated. This is accomplished by displacing a known volume of water from a well and measuring the artificial fluctuation of the groundwater level PDF Standard aquifer tests in low-permeability sediments arc of doubtful value because of the ambiguity and spread of the derived plots that drive the Find, read and cite all the By measuring and recording the rate of return of the water level toward static conditions (recovery), it is 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 With the slug test the hydraulic conductivity or trans missibilitv of an aquifer is determined from the rate of rise of the water level in a well after a certain volume or 'slug.
