Tennessee Aquifer Outcrops, Physiographic Provinces, and Recharge Rates

A polygon coverage of Tennessee attributes each region with its physiographic province name, aquifer type and composition, and aquifer recharge rates. The dataset was created to make generalizations about aquifer transport and recharge capabilities and to name those regions. It is provided by the organization CEOS_EXTRA via the NASA Earthdata platform.

Use Cases

• Model groundwater transport potential based on attributed aquifer type and composition.
• Estimate regional water recharge capacity based on polygon-attributed recharge rates.
• Map and name physiographic regions for geological studies based on the attributed province names.

Strengths

• Polygon features are attributed with specific data sources: physiographic regions (Miller, 1974), aquifer composition (Connell and Barron, 1993), and recharge rates (Hoos, 1990).
• The dataset has a clear stated purpose: to generalize aquifer capabilities and name regions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count, file formats, and license information are unknown, which may limit suitability assessment.
