This dataset contains measured (interval = 0.5 hour) wave height, peak wave period, water level, and water depth during March 1 to May 1, 2019, at five wave gage locations along the Chincoteague Living Shoreline, Virginia. These wave gages were sampled continuously at 10 Hz to take 20-min bursts every 30 min. These data were used for the analysis of wave attenuation along the oyster-reef-based living shoreline.
Coastal Hydrology and Storm Surge Storm-surge is one of the most powerful and destructive elements of major storm events. Excessively high tides associated with storms can flood and inundate coastal areas, often moving sediment and altering coastal landscapes and drainages. USGS provides critical expertise in measuring storm surge and assessing conditions both before and after the storm. Through development of storm tide monitoring networks, data analysis, and data delivery, USGS provides vital information to help coastal communities prepare for and recover from storm surge events.

Hydrogeologic and Geochemical Assessment of the Effects of Leakage from the Catskill and Delaware Aqueducts on the Local Bedrock and Overburden Aquifers in Southeastern New York
PROBLEM As part of an effort to sustain a viable water-supply system for 8 million residents in New York City, and 1 million other residents in upstate New York that rely on City water, the New York City Department of Environmental Protection (NYCDEP) has requested a multi-disciplinary study by the U.S. Geological Survey (USGS) to determine the source(s) of water to surface-water sites (springs and expressions) in areas adjacent to the Catskill Aqueduct. In the area near the Delaware Aqueduct, which has been determined by the USGS to have a water-tunnel contribution to flooding issues during periods of high precipitation, the NYCDEP plans to repair the leaks with a grouting procedure. However, without monitoring...
Field observations and spectral evolution of wind waves in Upper Delaware Bay with living shorelines
This dataset contains measured (interval=0.5 hour) water depth, wave height, and peak wave period during February 2 to April 4, 2018 at six wave gage locations along the Gandy's Beach, New Jersey in upper Delaware Bay. These data were used for the analysis of spectral evolution of wind waves along the coast in upper Delaware Bay with oyster-reef based living shoreline.
This dataset contains measured current velocity during March 1 to May 2, 2019, at eleven locations along the Chincoteague Living Shoreline, Virginia.
Field observation of current velocities (2018) in Gandy’s Beach, New Jersey with living shoreline structures
This dataset contains measured (interval=20 minutes) current velocity during February 1 to April 4, 2018 at seven locations along the Gandy's Beach, New Jersey in upper Delaware Bay. These data were used for the analysis of current pattern dynamics along the coast in upper Delaware Bay with oyster-reef based living shoreline structure for shoreline protection.
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...
