General information for each basin is entered by selecting a basin and choosing the Basin Data dialog. If multiple basins are selected, some fields will not be able to be edited (e.g. Basin name and Area), while others will be "grayed out". These other fields are in Multi-select mode. If you select and assign data to these fields, this data is assigned to all the selected sub-basins.
Area
When a TIN, DEM, or Map-based model is present, basin areas and slopes can be computed automatically using the Compute Basin Data command in the TIN or DEM Drainage module menus, or in the Feature Objects Map module menu. If a TIN, DEM, or map data are not present, areas and slopes must be entered interactively using the topological tree as a map. Areas should be entered in square miles.
