Shapefile of SFWMD basins as defined in their ArcHydro Enhanced Database (AHED) (AHED_basins.shp)

The South Florida Water Management District (SFWMD) and the U.S. Geological Survey have developed projected future change factors for precipitation depth-duration-frequency (DDF) curves at 174 NOAA Atlas 14 stations in central and south Florida. The change factors were computed as the ratio of projected future to historical extreme precipitation depths fitted to extreme precipitation data from various downscaled climate datasets using a constrained maximum likelihood (CML) approach. The change factors correspond to the period 2050-2089 (centered in the year 2070) as compared to the 1966-2005 historical period.
The SFWMD manages the water resources of various interconnected basins in south Florida, which are defined in the SFWMD ArcHydro Enhanced Database (AHED). The SFWMD is interested in summarizing change factors for each individual AHED basin to use in future planning efforts. Geospatial data provided in an ArcGIS shapefile are described herein. The shapefile contains polygons for the basins defined in the South Florida Water Management District (SFWMD)'s ArcHydro Enhanced Database (AHED) including their acreages.
