The Crustal Geophysics and Geochemistry Science Center in cooperation with the Nebraska Water Science Center has completed airborne geophysical surveys of selected areas of the North and South Platte River valleys of Nebraska, including Lodgepole Creek valley, and collected data to map aquifers and bedrock topography and thus improve the understanding of groundwater - surface-water relationships to be used in water management decisions. The two- and three-dimensional interpretations provide the groundwater modeler with a high-resolution hydrogeologic framework to improve understanding of the flow-path orientation by refining the location of paleochannels and associated base of aquifer highs. http://pubs.er.usgs.gov/publication/sir20115219
Three-dimensional display showing inverted time-domain electromagnetic soundings and airborne electromagnetic sections from the 2008 flights of the North Platte Natural Resources District. Bedrock picks derived from these data, as well as other complimentary data, are shown with their corresponding confidence metric.
