Description: This line dataset (PP1770_alt_base_LKA_con.shp) consists of contours of equal base altitude, in feet, for the lower Arapahoe aquifer of the Denver Basin aquifer system, Colorado. A point dataset was generated in ArcGIS 9.2 (Environmental Systems Research Institute, Inc., 1999-2004) from the Colorado Division of Water Resources Denver Basin geophysical log database (Brian Ahrens, Colorado Division of Water Resources, written commun., 2003), and the point data were contoured using either an ordinary kriging method or an inverse-distance weighted method available in ArcGIS, depending on which method resulted in the least error. This resulting dataset was then used to define the base altitude of the Arapahoe confining unit (model layer 9) in a MODFLOW-2000, three-dimensional groundwater-flow model of the Denver Basin (Paschke, 2011). See the "Supplemental Information" section of this metadata for more detailed descriptions of the datasets, their application, and references.
