Geospatial Data Presentation Form: map
Description:
Abstract: Basins are the USGS defined boundaries imported from the 1:24000 National Hydrography Dataset (NHD). They are defined by a six-digit Hydrologic Unit Code (HUC) in NHD. Basins are the highest level drainage units that fit within the South Florida Water Management District. The next-higher-level, the four-digit Subregion, covers the entire Florida peninsula. The HUC Code is stored in the NHD_HUA_CODE field. The boundary details have been edited to match AHED WATERSHED boundaries. Topology rules are enforced among features of Basin, Subbasin, Watershed, SubWatershed and Rainarea in AHED.
Purpose: AHED (Arc Hydro Enhanced Database) provides a geographically comprehensive database of hydrographic and hydrologic features for the South Florida Water Management District (SFWMD).

Detailed Description:
Entity Type:
Entity Type Label: BASIN
Entity Type Definition: These are the USGS defined Basins imported from the 1:24000 NHDinGEO database. They are defined by a six-digit Hydrologic Unit Code (HUC) in the NHD. Formerly known as accounting units, Basins are the highest level drainage units that fit within the South Florida Water Management District. The next-higher-level, the four-digit Subregion, covers the entire Florida peninsula. The intent is to use the Name field for the common drainage area name, The HUC Code is stored in the NHD_HUA_CODE field.
