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 = &amp;gt; 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.</SPAN></P></DIV></DIV></DIV> U.S. Geological Survey; Befus, K.M., Hoover, D.J., Barnard, P.L., and Erikson, L.H., 2020, Projected responses of the coastal water table for California using present-day and future sea-level rise scenarios: U.S. Geological Survey data release, https://doi.org/10.5066/P9H5PBXP. 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.
