Befus originator U.S. Environmental Protection Agency Center for Public Health and Environmental Assessment publisher imageDigital Water table depths for different scenarios. Future coastal groundwater hazards along the U.S. North Eastern coasts Groundwater emergence and shoaling extents are derived from water table depth GeoTIFFs, which are calculated as steady-state groundwater model heads subtracted from high-resolution topographic digital elevation model (DEM) land surface elevations. Results are provided as image services of water table depth in specific depth ranges (lt 0 m, 0 m, 1 m, 2 m, 3-5 m, gt 5 m). Scenarios include: Kzell0p1_slr0p00m, Kzell0p1_slr0p25m, Kzell0p1_slr0p50m, Kzell0p1_slr1p00m, Kzell0p1_slr1p50m, Kzell0p1_slr2p00m, Kzell0p1_slr2p50m, Kzell0p1_slr3p00m, Kzell1_slr0p00m, Kzell1_slr0p25m, Kzell1_slr0p50m, Kzell1_slr1p00m, Kzell1_slr1p50m, Kzell1_slr2p00m, Kzell1_slr2p50m, Kzell1_slr3p00m, Kzell10_slr0p00m, Kzell10_slr0p25m, Kzell10_slr0p50m, Kzell10_slr1p00m, Kzell10_slr1p50m, Kzell10_slr2p00m, Kzell10_slr2p50m, Kzell10_slr3p00m. This series of image services display water table depth for various sea level rise scenarios and hydraulic conductivity multipliers of 0.1, 1, or 10.

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. EPA Public Domain License https://edg.epa.gov/EPA_Data_License.html unclassified notPlanned
