Projections for future sea-level rise provide emergency responders and coastal planners with critical hazards information that can be used to increase public safety, mitigate physical damages, and more effectively manage and allocate resources within complex coastal settings. These data are intended for policy makers, resource managers, science researchers, students, and the general public. These data can be used with geographic information systems or other software to identify and assess possible areas of vulnerability. These data are not intended to be used for navigation. This data release was funded by EPA. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.

Attribute values are model-derived water table depths for present-day and future sea-level rise conditions. The model uses parameters from calibrated and published groundwater models and is intended to show the general response of the shallow coastal water table to sea-level rise. Water table depths are calculated relative to the best-available ground surface elevations from available digital elevation models (DEMs), but DEM inaccuracies introduce additional uncertainty into calculated water table depths. Projected water tables for future sea-level rise conditions cannot be validated against observations.
Data have undergone quality checks and meet standards.
Dataset is considered complete for the information presented. Users are advised to read the metadata record carefully for additional details.
Data are concurrent with topographic digital elevation model (DEM) locations.
Model-derived head elevations are accurate within the limitations of the model. The model uses parameters from calibrated, published groundwater models, but limitations due to model resolution and uncertainty in model parameter values may significantly affect modeled head elevations. For water table depths, modeled heads are subtracted from land surface elevations from the best available digital elevation models (DEMs). DEM inaccuracy will introduce additional uncertainty into water table depth results. As a result, water table depth results are intended to show only the general response of the shallow coastal water table to sea-level rise.
Individual water table depth TIFs by state were mosaicked together for each scenario, then published as image services. The image services include SLR scenarios with hydraulic conductivity multipliers of 0.1, 1, and 10.
