The upper-Claiborne confining unit overlies the Memphis aquifer in Shelby County, Tennessee. Hydrogeologic windows are locations where clay intervals are thin or absent within the confining unit, resulting in localized vertical recharge. Previous work has not been geostatistically focused. In this study, 430 borehole geophysical logs were analyzed. The objectives were to: 1) capture and analyze exisiting well log data in a geodatabase 2) utilize geostatisitical modeling at a variety of scales 3) integrate well log data with historic water-table elevation trends and 4) produce multi scaled maps that illustrate hydrostratigraphic trends in terms of inter-aquifer communication. Geostatisitical ordinary kriging …
