|Abstract:||The U.S. North Atlantic coast is subject to coastal flooding as a result of tropical cyclones (e.g., hurricanes) and severe extratropical cyclones (e.g., Nor’easters). The North Atlantic Coast Comprehensive Study (NACCS) seeks to quantify existing and future forcing for use in assessing potential engineering projects that would reduce flooding risk and increase resiliency. The study encompasses the coastal region from Virginia to Maine. This report describes the characterization of storm climate and statistical analysis of coastal storm hazards for the NACCS. The overall NACCS wave and water level modeling goals included simulating an efficient number of storms that blanketed a sufficient range of storm characteristics in order to accurately describe the statistical nature of coastal storm response over the entire region. This information is required for modern probabilistic project design and for risk assessments. For this study, storm surge, tide, waves, wind, atmospheric pressure, and currents were the dominant storm responses computed. The effect of sea level change on these storm responses was assessed. The significant advancements in this study included a dense spatial coverage of nearshore storm response for the region, high-fidelity computations, a comprehensive description of the aleatory variability of response from frequent storm events to extremely rare events, a description of epistemic uncertainty, characterization of the statistical nature of the data in easily ingestible, relatively simple data formats, and public distribution of data and statistics within the Coastal Hazards System, a web-based coastal storm data resource.|
