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. The measurements are recorded and analyzed by one or more

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).

This is accomplished by displacing a known volume of water from a well and measuring the artificial fluctuation of the groundwater level. The primary advantages of using slug tests to estimate hydraulic conductivities • A volume “slug” of water is quickly added to or removed from a well. •Commonly used and well established test. •The aquifer response is used to estimate hydraulic conductivity.

So, the amount of expansion the test found will likely be less in our quarry. However, your test clearly shows how this first batch of FX .25cal slugs isn't expanding easily — even under ideal conditions of using water as ballistic medium…. Using the ChairGun ballistic calculator I come up with an impact velocity of the FX slug of 878fps.

Slugtest används vanligtvis för beräkning av jordens hydrauliska konduktivitet, och är egentligen ett förenklat pumpförsök. Slugtestet genomfördes genom att vatten fylldes på i rören och därefter Provtagningen utfördes med dränkbar pump som sänktes ned 0,5-1 meter 1,00. 10,00. 100,00.

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. To provide a larger scale comparison to slug test estimates of hydraulic conductivity for unweathered Wisconsin age till in Iowa, a pumping test was performed, with both the pumping and monitoring wells placed in unweathered till. A slug test is a variation on the typical aquifer test where an instantaneous change (increase or decrease) is made, and the effects are observed in the same well.

The Lugeon test (commonly known as the "packer test") is a common test used to estimate the in-situ permeability of a rock mass. The Packer test is carried out over a specific length (typically 3 pumping tests. Pump tests values are generally considered to better represent aquifer behavior (Butler and Healey, 1998). A slug test induces a rapid change in water level in a slugged well, and then one observes how fast the water level returns to equilibrium.
