Background The North Atlantic Coastal Plain (NACP) covers a land area of approximately 34,000 mi 2 along the eastern seaboard of the United States from Long Island, N.Y., southward to the northern portion of North Carolina. This area is underlain by a thick wedge of sedimentary deposits that form a complex groundwater system in which the sands and gravels function as confined aquifers, and the silts and clays function as confining units. These confined aquifers of the NACP constitute a major source of water for public and domestic supply for the nearly 27 million people living in the region, as well as being important source of water for industrial and agricultural purposes. Increases in population and changes...

The study will: 1) improve the integration of state water-use and water supply data; 2) develop a basin-wide surface-water hydrologic model capable of evaluating the impacts of land-use change, climate change, and changes in water demand; and 3) develop a scientific approach to defining relations between streamflow processes and the responses of aquatic organisms in tributary streams.

Following Hurricane Sandy, the USGS began construction of an overland Surge, Wave, and Tide Hydrodynamics (SWaTH) Network along the Northeastern Atlantic Coast from North Carolina to Maine. This network, developed collaboratively with numerous partners, features the integration of long-term tide gage networks, with real-time rapid-deployment gages (RDG) and mobile storm-tide sensors (STS). An element of the comprehensive strategy of SWaTH ensures that locations for most RDGs and STSs have been presurveyed to the North American Vertical Datum of 1988 (NAVD 88) and equipped with receiving brackets. This permits rapid deployment and recovery of instrumentation and data dissemination in the hours and days immediately...
