För att jämföra olika testmetoder genomförs olika tester i samma grundvattenrör. De testmetoder som bör ingå i studien är: •. Slugtest med solid

Figure 1. 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

This weighted spatial averaging can be mathematically repre-sented as a spatial-filtering operation [Beckie, 2001], 5.2 The slug test provides an advantage over pumping tests in that it does not require the disposal of the large quantities of water that may be produced. This is of special importance when testing a potentially contaminated aquifer. However, slug tests reflect conditions near the well, therefore are influenced by near-well conditions, such as gravel pack, poor well development, and skin GGU-SLUGTEST supports six different evaluation models: Hvorslev; Bouwer-Rice; Cooper; Dougherty; Mönch; Ramey; Capabilities: Import data from data loggers We recently used your pneumatic Hi-K Slug test kit on a project with numerous wells. The kit was easy to use, saved us time, and eliminated cleaning that is required using a traditional solid slug. The best part is that the Hi-K kit provided excellent results with smooth test data that was free of early oscillations typical of solid slug tests.

Parameter-estimation methods, including an exhaustive-search method and PEST (Parameter ESTimation) software, were applied to recovery-test data and slug-test data to obtain best estimates of transmissivity (T) by minimizing the sums of residuals. Each …

When environmental monitoring wells PDF | We consider parameters determined by the inversion of slug-test head recovery data with the homogeneous-parameter model of Cooper et al.

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. 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).

Ett slug-test mäter hydraulisk konduktivitet i en akvifer genom ett borrhål, vilket gör att uppskattningen av akviferens material bara blir till den del man borrat i. Resultatet kan även bli påverkat av att lösgjort material från borrningen blandar sig i provet

Field Setup and Slug Test for Groundwater Sampler or Direct Push Monitoring Well. The Slug Test Manifold is threaded onto the top of the rods or installed with an adapter on well casing. Either an O-ring or Teflon ® tape is used to seal the surface connection and at each joint. GGU-SLUGTEST is a bilingual program. The program always starts with the language setting applicable when it was last ended. The language preferences can be changed at any time in the "Info" menu, using the menu item "Spracheinstellung" (for German) or "Language preferences" (for English).
