| description:
|
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 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 level rise is added directly to the full model present-day (SLR 0m) water table. Each full model Kh folder contains depth-to-groundwater shapefiles for all twelve of the sea level rise scenarios (0 - 2m in 0.25m increments, 2.5m, 3m, and 5m), while linear Kh folders contain depth-to-groundwater shapefiles only for the 11 non-zero SLR cases, because the linear SLR 0m case is identical to the full model SLR 0m case. |
