Description: Aquifer Transmissivity (IDNR) - Shows aquifer transmissivity values calculated for selected river basins in Indiana (Kankakee River Basin, the Lake Michigan Region, the Maumee River Basin, the West Fork of the White River Basin, and the Whitewater River Basin). Transmissivity is the measure of how much water can be transmitted horizontally through a unit width of a fully saturated aquifer.
Transmissivity estimates can be used by geothermal heat pump installers to design more efficient open loop ground-coupled systems, since the performance of injection wells is dependent upon the transmissivity of the aquifer in which the well is screened.
These data were produced in 2011 by the Indiana Geological Survey as part of an effort to populate the National Geothermal Data System (NGDS, http://www.geothermaldata.org). This material is based upon work supported by the Department of Energy and the Arizona Geological Survey under Prime Award Number DE-EE0002850 and Sub-Award Number IN-EE002850.
