USGS Flood Information

Past Flood Events | 2012 | Hurricane Isaac | Hurricane Sandy

USGS scientists, engineers, and technicians worked along the Gulf coast in response to Hurricane Isaac, deploying and maintaining storm tide sensors real-time streamgages in anticipation of Isaac's arrival. The USGS, in concert with our partners, is providing scientific assessments of the challenges wrought by Isaac.

USGS Open File Report: Monitoring Storm Tide and Flooding from Hurricane Isaac along the Gulf Coast of the United States, August 2012: a report prepared under a mission assignment with the Federal Emergency Management Agency detailing coastal area data collection by the USGS.

The data from the Hurricane Isaac storm-tide network constitute an extensive collection of continuous water-level records documenting a single, landfall hurricane. The data can be used to evaluate the performance of storm-tide models for maximum and incremental water level and flood extent and for site-specific effects of storm tide on natural and anthropogenic features of the environment.
