    • Geospatial Datasets of Factors Influencing Groundwater Emergence Flood Hazard in Long Island, New York and Near Coastal Areas Surrounding Long Island Sound in New York, Connecticut, and Rhode Island

    Metadata Updated: September 4, 2025

    This data release contains raster datasets representing depth to water table, calculated from steady-state groundwater models developed by the U.S. Geological Survey (Jahn and others, 2024; Barclay and others, 2024). The depth to water table rasters are available at an approximate resolution of 10 meters. In addition, depth to water table, hydrologic soil types, and landcover are harmonized to a common 900-meter by 900-meter polygrid and a groundwater emergence flood hazard rank calculated for each grid cell according to methods described in (Masterson and others, 2025). A second groundwater emergence flood hazard rank was calculated for Long Island based on a sea-level rise scenario (Jahn and others, 2024) of 6 feet above North American Vertical Datum of 1988 (NAVD 88).
