Webthe slug test. This latter parameter is signed—a slug-in test raises the water level and generates a positive H WO, followed by a falling water column in the well (falling-head slug test). A slug-out test lowers the free surface, and is signiﬁed by a negative H WO and a subsequent inﬂux of groundwater into the well (rising-head slug test). Webthe slug test.

"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 the near-well aquifer characteristics. It is a method used by hydrogeologists and civil engineers to determine the transmissivity/hydraulic conductivity and storativity of the material the well is completed in. " - Falling head slug test
