Digital hydraulic conductivity values
Listed in NASA Earthdata CMR
This data set was created for a project to develop data sets to support ground-water vulnerability analysis.
Description
The objective was to create and document a digital geospatial data set from a published report or map, or existing digital geospatial data sets that could be used in ground-water vulnerability analysis. This data set consists of digital hydraulic conductivity values for the alluvial and terrace deposits along the Beaver-North Canadian River from the panhandle to Canton Lake in northwestern Oklahoma.
Ground water in 830 square miles of the Quaternary-age alluvial and terrace aquifer is an important source of water for irrigation, industrial, municipal, stock, and domestic supplies. The aquifer consists of poorly sorted, fine to coarse, unconsolidated quartz sand with minor amounts of clay, silt, and basal gravel. The hydraulically connected alluvial and terrace deposits unconformably overlie the Tertiary-age Ogallala Formation and Permian-age formations.

Six zones of ranges of hydraulic conductivity values for the alluvial and terrace deposits reported in a ground-water modeling report are used in this data set. The hydraulic conductivity values range from 0 to 160 feet per day, and average 59 feet per day. The features in the data set representing aquifer boundaries along geological contacts were extracted from a published digital surficial geology data set based on a scale of 1:250,000.
The geographic limits of the aquifer and zones representing ranges of hydraulic conductivity values were digitized from folded paper maps, at a scale of 1:250,000 from a ground-water modeling report. Ground-water flow models are numerical representations that simplify and aggregate natural systems. Models are not unique; different combinations of aquifer characteristics may produce similar results.
Therefore, values of hydraulic conductivity used in the model and presented in this data set are not precise, but are within a reasonable range when compared to independently collected data.
