Contour lines depict the elevation of the base of the surficial aquifer system in Dade County, Florida. The map uses a 20-foot contour interval, with the base generally between 180 and 220 feet below sea level. This dataset was produced by the U.S. Geological Survey in cooperation with the South Florida Water Management District, with a last update recorded in 1987.
Use Cases
- Model groundwater flow paths and aquifer geometry using the base elevation contours.
- Estimate aquifer thickness by comparing surface elevation data with the provided base contours.
- Delineate the regional extent of the surficial aquifer system for water resource management planning.
- Analyze spatial variability in the aquifer's basal elevation across Dade County.
Strengths
- Contour interval is a defined 20 feet.
- Specific elevation range provided (180 to 220 ft below sea level).
- Produced by the authoritative U.S. Geological Survey.
Limitations
- Data is from 1987 and may not reflect current hydrogeological conditions.
- Specific row count, column details, and sample data are unavailable.
- Focus is primarily on Dade County, with limited coverage of adjacent Broward and Palm Beach Counties.
