Projected groundwater emergence and shoaling for coastal California using present-day and future sea-level rise scenarios

Groundwater emergence and shoaling extents are derived from water table 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 shapefiles of water table depth in specific depth ranges, with the following data coding in the "fbin_m" data column: -1 = marine inundation (below marine boundary condition (LMSL or MHHW) sea level) 0 = water table at or above ground surface (emergent groundwater) 1 = water table between 0-1 m depth (very shallow) 2 = 1-2 m depth (shallow) 5 = 2-5 m depth (moderate) 6 = > 5 m depth (deep) Model results are aggregated by County, with separate County...

Projected water table depths for coastal California using present-day and future sea-level rise scenarios

Depth to groundwater (water table depth) results are calculated as steady-state groundwater model head results subtracted from high-resolution topographic Digital Elevation Model (DEM) land surface elevations. Results are provided here as GeoTIFF rasters of water table depth. See Groundwater_head_and_water_table_depth_methods.pdf for additional details. Model results are aggregated by County, with separate County files for model results using the Local Mean Sea Level (LMSL) and Mean Higher-High Water (MHHW) marine boundary conditions. Each zipped County datafile (County_MHHW or County_LMSL) contains 6 folders: 3 containing full model results for each of the three horizontal hydraulic conductivities (Kh) used in...

Projected groundwater head for coastal California using present-day and future sea-level rise scenarios

Groundwater head (water table elevation relative to NAVD88) results are from steady-state groundwater models. Results are provided here as GeoTIFF rasters of groundwater head. See Groundwater_head_and_water_table_depth_methods.pdf for additional details. Model results are aggregated by County, with separate County files for model results using the Local Mean Sea Level (LMSL) and Mean Higher-High Water (MHHW) marine boundary conditions. Each zipped County datafile (County_MHHW or County_LMSL) contains 6 folders: 3 containing full model results for each of the three horizontal hydraulic conductivities (Kh) used in the model (0.1, 1.0 and 10 m/d), and 3 containing "linear" results for each of the 3 Kh's, where sea...
