Description:The U.S. Geological Survey (USGS) deployed a temporary monitoring network of water-level sensors at 212 locations along the Atlantic coast from Maryland to Maine during October 2012 to record the timing, areal extent, and magnitude of inland hurricane storm tide and coastal flooding generated by Hurricane Sandy. Water-level sensor locations were selected to augment existing tide-gage networks to ensure adequate monitoring in areas forecasted to have substantial storm tide. Storm tide, as defined by the National Oceanic and Atmospheric Administration (NOAA; November 2011a,b ), is the water level rise generated by a coastal storm as a result of the combination of storm surge and astronomical tide. Hurricane Sandy initially made landfall just south of Atlantic City, NJ around 7pm EDT on October,29 2012, as a category 1 hurricane on the Saffir-Simpson hurricane scale (National Hurricane Center, 2010).
