At-site flood frequency for 139 urban streamgages in Tennessee and parts of Alabama, Georgia, Mississippi, North Carolina, and South Carolina using data through water year 2022
This dataset contains site information and results of flood-frequency analysis for 139 urban streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) in Tennessee and parts of Alabama, Georgia, Mississippi, North Carolina, and South Carolina. Developed imperviousness in the basins, based on the 2011 National Land Cover Database, was at least 10 percent (Homer and others, 2015). Drainage areas of the streamgage basins ranged from 0.15 - 161 square miles. Annual peak-flow data from the 1947 - 2022 water years were used in the study (U.S. Geological Survey, 2024). Peak-flow (.pkf), specification (.psf), output (.PRT), and export (.EXP) files from flood-frequency analysis in USGS PeakFQ software (Veilleux and others, 2014; Flynn and others, 2006) are provided. Site information and results of flood-frequency analysis are provided in .csv format.
