Upper Floridan Aquifer potentiometric surface raster, wet season 2022

Usage

contwet

Format

A PackedSpatRaster (see wrap) representing a 1-mile resolution grid of potentiometric head (ft above MSL) for the wet season. Unwrap with terra::unwrap(contwet) to obtain a SpatRaster.

Details

Interpolated from Upper Floridan Aquifer potentiometric surface contour lines (September 2022) downloaded from the FDEP / Florida Geological Survey ArcGIS REST service using util_gw_getcontour. The spatial extent covers the Tampa Bay watershed (tbfullshed) buffered outward by 40 miles. Interpolation used inverse distance weighting (IDW, 5-mile radius, power = 2) followed by five passes of a 3x3 focal mean gap fill. Projection is NAD83(2011) / Florida GDL Albers (ftUS), CRS 6443.

Dry season equivalent is contdry.

contwet <- terra::wrap(pot_wet)
