Geospatial Dataset of Coastal Inundation Maps for Long Island, NY and Long Island Sound (CT/NY)

This data release contains shapefiles and raster data of spatially distributed water level inundation, water depth, wave discharge and a set of hazard ranks for water levels, waves, and a combination of both for coastal areas of Long Island, NY and Long Island Sound. Water inundation and depth data include both current and future projections of inundation based on 4 annual exceedance probabilities (0.01, 0.04, 0.1, and 0.99). The wave discharge data is calculated for current conditions only. Future flood-inundation data are based on sea-level-rise model scenarios from the GTSM model (Copernicus Climate Change Service, 2022a, 2022b, and Muis et al 2020). Read the README.txt file for a description of file contents.  Additional information supporting this data release is available in the associated manuscript Cook and Herdman (2025).
