Estimating flood magnitude and frequency for urban and small, rural streams in Georgia, South Carolina, and North Carolina, 2011
Reliable estimates of the magnitude and frequency of floods are essential for the design of transportation and water-conveyance structures, flood insurance studies, and flood-plain management. Flood-frequency estimates are particularly important in densely populated urban areas. The U.S. Geological Survey (USGS) used a multistate approach to update methods for determining the magnitude and frequenAuthorsToby D. Feaster, Anthony J. Gotvald, J. Curtis WeaverMonitoring storm tide and flooding from Hurricane Sandy along the Atlantic coast of the United States, October 2012
The U.S. Geological Survey (USGS) deployed a temporary monitoring network of water-level and barometric pressure sensors at 224 locations along the Atlantic coast from Virginia to Maine to continuously record the timing, areal extent, and magnitude of hurricane storm tide and coastal flooding generated by Hurricane Sandy. These records were greatly supplemented by an extensive post-flood high-wateAuthorsBrian E. McCallum, Shaun Wicklein, Robert G. Reiser, Ronald Busciolano, Jonathan Morrison, Richard J. Verdi, Jaime A. Painter, Eric R. Frantz, Anthony J. GotvaldMagnitude and Frequency of Floods for Urban and Small Rural Streams in Georgia, 2008
A study was conducted that updated methods for estimating the magnitude and frequency of floods in ungaged urban basins in Georgia that are not substantially affected by regulation or tidal fluctuations. Annual peak-flow data for urban streams from September 2008 were analyzed for 50 streamgaging stations (streamgages) in Georgia and 6 streamgages on adjacent urban streams in Florida and South CarAuthorsAnthony J. Gotvald, Andrew E. KnaakEpic Flooding in Georgia, 2009
Metropolitan Atlanta-September 2009 Floods The epic floods experienced in the Atlanta area in September 2009 were extremely rare. Eighteen streamgages in the Metropolitan Atlanta area had flood magnitudes much greater than the estimated 0.2-percent (500-year) annual exceedance probability.
