Greene, D.C., and Wolfe, W.J. 1998 digital data Reston, Virginia U.S. Geological Survey http://water.usgs.gov/lookup/getspatial?aquiphys This dataset is a coverage of the physiographic provinces, aquifer outcrops and recharge rates for Tennessee. Each polygon is attributed with its associated physiographic region name (Miller, 1974), aquifer type and composition (Connell and Barron, 1993, p. 2), and aquifer recharge rates (Hoos, 1990 p. 19). The dataset was created to make generalizations about an aquifer's capabilities of transport and recharge and to give names to those regions. Procedures_Used: The linework was constructed by digitizing a map, prepared by Bradley and Hollyday (1985), at a scale of 1:1,000,000. At the request of State officials, aquifer boundaries in the West Tennessee area were modified to reflect work reported by Parks and others (1982). The coverage was created for the publication by Connell and Barron (1993). The coverage was validated and attributed with physiographic names and aquifer recharge rates in 1997-98. Revisions: 03/15/97 - Coverage was found valid, and attributed with physiographic names 04/03/98 - Aquifer recharge rates were attributed Reviews_Applied_to_Data: The dataset was reviewed by several Tennessee District personnel and was deemed a valid dataset for use at the documented scale.

The AQUIFER field contains the principal aquifer designation per Connell and Barron, 1993: Al - Alluvial underlain by Tertiary and Cretaceous sand (unconfined or confined) T-sand(conf) - Tertiary sand (confined), underlain by Cretaceous sand (confined) T-sand(uncf) - Tertiary sand (unconfined), underlain by Cretaceous sand (confined) C-sand - Cretaceous sand (unconfined) Al(C-sand) - Alluvial, underlain by Cretaceous sand M-carb - Mississippian carbonate O-carb - Ordovician carbonate P-sand - Pennsylvanian sandstone O-carb(fault) - Ordovician carbonate (faulted) C/O-carb - Cambrian-Ordovician carbonate C-rock - Crystalline rock The REGION field labels the polygon with the name given to that physiographic province per Miller, 1974. The RECHARGE field applies only to middle and east Tennessee. The data represents the recharge rates in inches per year during an average flow year per Hoos, 1990.
