In hydrogeology, 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 …

This is called a falling head test or “slug in test.” After the water level reaches equilibrium, quickly removing the slug causes the water level to fall instantaneously.

Nov 18, 2019 · Slug tests are used in groundwater hydrology to determine the hydraulic properties of confined, unconfined and fractured aquifers.

If a partially penetrating well cannot be installed (groundwater less than 3 feet below grade), a slug-in test must be conducted on fully penetrating wells, i.e. completely submerged well screens.

saturated-screened interval. Slug tests are ideal for determining the hydraulic parameters for wells ranging from 2- to 6-inch diameter in low to medium permeability formations (e.g., can be pumped or …

Jun 11, 2025 · Discover the importance of slug tests in hydrology, their applications, and how to conduct them effectively for reliable groundwater data.

In this informative video, we will guide you through the process of performing a slug test, a commonly used technique in civil engineering to assess groundwater characteristics. You’ll learn...

A slug test is defined as a method that involves creating a brief pulse of head change at a point in an aquifer and observing the transient recovery of the piezometric level to measure transmissivity and …

A slug test involves the instantaneous injection or withdrawal of a volume or slug of water or solid cylinder of known volume. This is accomplished by displacing a known volume of water from a well …
