Hydraulic Tomography and High-Resolution Slug Testing to Determine Hydraulic Conductivity Distributions - Year 3

A typical method used to determine fluid behavior in a geologic matrix near a well is a pumping test Here a pump is installed into a well and groundwater is removed or injected while water levels in surrounding observation wells are monitored. Then the aquifer parameters can be estimated by monitoring changes in water levels at observation wells at some distance These types of tests are typically large in scale, Schad and Teutsch, 1994 Another test is an interference test, which is a special pumping test where the pump discharge has a variable rate Interference tests are conducted by variable production or injection fluid hydraulic head changes at one well, and observing the changing pressure or hydraulic head with time and distance at other locations These tests are valued to estimate flow characteristics hi situ, but are measures of the aquifer material over large volumes also.
