New Report: Methods for Estimating the Magnitude and Frequency of Floods for Urban and Small, Rural Streams in Georgia, South Carolina, and North Carolina
The USGS recently released a report describing updated flood-frequency statistics and techniques for urban and small, rural basins in Georgia, South Carolina, and North Carolina.
Methods for Estimating the Magnitude and Frequency of Floods for Urban and Small, Rural Streams in Georgia, South Carolina, and North Carolina, 2011
Similar to the recent update of flood-frequency (FF) statistics and techniques for rural basins in the same three states, the updated techniques in this report can be used to estimate flood-frequency statistics for urban and small rural (less than 1 sqmi) streams in the Piedmont, Sand Hills, and Coastal Plain regions in North Carolina. The techniques were developed via analyses of observed annual peak-flow records at 488 urban and rural USGS streamgages across a multi-state region. Availability of the updated techniques is considered to provide a stronger set of relations for estimating flood-frequency statistics for these basins.
The online site for the report provides a spreadsheet application tool (XLS, 1.58 MB) to help users quickly estimate the flood-frequency statistics for a site of interest.
