Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>SubWatersheds are the next level of drainage areas under Watersheds and smallest units classified in AHED (Arc Hydro Enhanced Database). They were formerly known at the District as Subbasins. Subwatersheds are the 12 Digit HUC (Hydrologic Unit Code) under USGS categorization of drainage areas. AHED does not populate HUC from NHD because there is not a one to one correspondence between the features.</SPAN></P></DIV></DIV></DIV>

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Watersheds are the next level of drainage areas larger than Subwatersheds. They represent the USGS 10 Digit Hydrologic Unit Code (HUC) drainage areas. Watershed boundaries were updated by incorporating SFWMD subject matter experts advice and newer data from business units when available. The HUC code from USGS is not populated for AHED Watersheds because there is not a one to one correspondence between the two datasets. In AHED, topology rules are enforced among the features of Basin, Subbasin, Watershed, SubWatershed and Rainarea feature classes.</SPAN></P></DIV></DIV></DIV>

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Subbasins are grouped from Watershed boundaries and are consistent with NHD (National Hydrography Dataset) Subbasins. In areas where AHED Watersheds need major changes, the subsequent change in Subbaisn boundary will be communicated with USGS and NRCS (Natural Resources Conservation Service). Subbasins are USGS drainage areas one level smaller than Basins and each have a unique 8 Digit Hydrologic Unit Code or HUC. Topology rules are enforced among features of Basin, Subbasin, Watershed, SubWatershed and RainArea.</SPAN></P></DIV></DIV></DIV>

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>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.</SPAN></P></DIV></DIV></DIV>
