A 1997-98 validated geospatial dataset covering Tennessee's physiographic provinces, aquifer outcrops, and recharge rates. The dataset was created for a publication by Connell and Barron (1993) and digitized from a 1:1,000,000-scale map prepared by Bradley and Hollyday (1985). It includes attributes for physiographic region names, aquifer type and composition, and aquifer recharge rates.
Use Cases
- Model groundwater recharge potential based on attributed aquifer recharge rates.
- Map aquifer outcrop boundaries based on digitized polygon data.
- Analyze the relationship between physiographic provinces and aquifer composition based on attributed region names and aquifer types.
Strengths
- Dataset was validated and reviewed by Tennessee District personnel.
- Attributes include specific references to source publications (Miller, 1974; Connell and Barron, 1993; Hoos, 1990).
- Aquifer boundaries were modified based on later work reported by Parks and others (1982).
Limitations
- Row count, column names, and file formats are unknown.
- Last update date is unknown; freshness unverified.
- Data is documented for use at a specific scale (1:1,000,000), limiting applicability at finer resolutions.
