Location and attributes for subbasins in the hydrologic analysis. The S_Subbasins table contains data specific to each subbasin in the hydrologic analysis, including the relationship of the subbasin to the hydrologic network. The subbasin may be specific to a detailed hydrologic model. It may also correspond to the drainage area used in a regression analysis, or to the drainage area for a stream gage. S_Subbasins is intended to store HUC8 information related to the hydrologic model. This information is used in the Basin Characteristics tables in the FIS report, as well as for the FIRM Panel Index Map. The spatial elements representing the subbasins are polygons. In some cases the extent of these polygons may overlap, for example, cumulative subbasin areas for a regression analysis. |
