I forbindelse med projektets gennemførelse blev der til bestemmelse af den hydrauliske ledningsevne K [m/s], gennemført en række slugtests, der dannede grundlag for beregning af den hydrauliske ledningsevne i den øvre moræneler til 4,5 meter under terræn. 1.1 Teori "By using real-world slug test data during the webinar, I was able to see right away how Jim Butler's guidelines improve the efficiency and confidence in hydraulic conductivity test results. The presentation's clear graphics and on-site examples made this a practical learning experience, and I will certainly be able to implement these ideas both in the field and in analysis."

The hydraulic conductivity in the im-mediate vicinity of the well can then be obtained by analyzing the AQTESOLV is the original all-in-one package for the design and analysis of aquifer tests, including pump test, step-drawdown tests, variable-rate tests, recovery tests, single-well tests and slug tests.AQTESOLV offers a vast array of aquifer test solutions for confined, unconfined, leaky and fractured aquifers with sophisticated options such as: Slug-test data were collected from 12 wells at the Hillview Reservoir during August 2007 and from 25 wells at the reservoir and 1 monitoring well south of the reservoir in northern Bronx County in June 2012. Hydraulic conductivity values at the reservoir ranged from 0.0012 to 2 feet per day. We usually use the Method of Bouwer and Rice (1976) to obtain hydraulic conductivity from raw slug test data. This method was originally published in an article entitled "Slug Test Procedure to Evaluate Hydraulic Conductivity of an Aquifer Applicable to Fully or … Naruto: Slugfest is an online role game that takes you back to Konoha so you can live a new adventure in this popular manga series.

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). 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. time data and well geometry parameters into a mathematical model to solve for K A slug test is designed to measure the hydraulic conductivity, or flow, of ground water near an aquifer by removing or displacing a slug of water or soil from below the ground and measuring the flow or pressure at which the ground water table changes.

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).
