Welcome!


Hydraulic conductivity measured by three methods. The Kansas Geological Survey's Well Tests for Site Characterization project is focused on the investigation of high-resolution aquifer characterization techniques, such as hydraulic tomography, and the identification and promotion of best practices for conventional well testing techniques, such as slug tests. For more information on this project, please contact Jim Butler or Geoff Bohling, project investigators. We are also doing related work on direct-push aquifer characterization techniques.

At left: Vertical profiles of hydraulic conductivity in the alluvial aquifer at the KGS Geohydrologic Experimental and Monitoring Site estimated from hydraulic tomography (blue), an induced gradient tracer test (red), and two direct-push permeameter profiles (green and black). From Bohling et al., 2007.
