Testvapnet är svartfosfaterat och försett med en likaledes svart syntetkolv. av L Söderberg · 2013 · Citerat av 2 — v models able to predict groundwater properties are an essential and cost-efficient e.g. multi-well pumping tests or single-well slug tests (Grip & Rodhe, 1994).

Sample Description 50/50 mix of kerosene and water Figure 1 – Sample description Typical Images Figure 2 - Steady state before valve is opened. Small droplets can be seen. SLUG TESTS Slug tests are generally conducted to determine the horizontal K of a ground water zone. A slug test involves the abrupt removal, addition, or displacement of a known volume of water and the subsequent monitoring of changes in water level as equilibrium conditions return.

Slug tests are used to determine in situ aquifer hydraulic conductivity more quickly and economically than by a pump test. This study 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 Feb 22, 2018 A slug test is basically a reverse pump test. A solid piece of PVC (or ABS) pipe, approximately 3 feet long in dropped into the well. This will cause 6.0 AQUIFER PUMPING TEST DATA ANALYSIS AND INTERPRETATION .. 19 Figure 6: Range of Slug Test Response to a Sudden Change in Head v by the specific capacity, slug, and aquifer (pumping) test methodologies. INTRODUCTION.

• 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.

Helt gratis! (1998) conducted slug test in wells with partially submerged screens. The slug test presents numerous pros, but also some cons. Indeed, the reliability of a slug test is less than a pumping test that, when it is possible to use, undoubtedly more accurately estimates perme-ability.

Barlow and Moench (1999) recently published the FORTRAN program WTAQ, which is based on radial axisymmetric flow to a well under confined or unconfined conditions. Sepulveda (1992) documented a FORTRAN program for analysis of underdamped and overdamped slug tests.

Some of the key features found in AQTESOLV include the following: ✓ Pumping Tests (constant rate, variable rate, step-drawdown and recovery) ✓ Slug Tests Slugtest är den enklaste metoden. Pumpvolymen justeras med målsättning att hitta en jämviktssituation där pumpningen och tillrinningen är lika stor. Slugtest (in – och utströmningsförsök). Slugtest används vanligtvis för beräkning av jordens hydrauliska konduktivitet, och är egentligen ett förenklat pumpförsök.
