A zipped polygon shapefile that contains a field (text or number) that represents a unique indentifier for each subbasin.

Select a Landuse .zip file:

A zipped polygon shapefile that includes information for interpreting % impervious (directly connect to outlet), initial moisture condition (component of DTHETA parameter), and surface storage (used in HEC-HMS).

Enter the subbasin name field:

The name of the field in the subbasins shapefile that contains unique identifiers for each subbasin.

Enter the land-use moisture field name:

A text field in the land-use shapefile that contains the assumed moisture condition for each land-use. Valid values areDry:"d", "dry", "D", "DRY"Field Capacity ("normal" moisture condition, moist):"m", "moist", "M", "MOIST"Saturated:"s", "sat", "S", "SAT"

Enter the land-use directly-connected impervious area field name:

The percent, expressed as a decimal from 0 to 100, of impervious area for each land-use area which is directly connected to a basin outlet.

Enter the land-use vegetative cover field name:

Percent (0-100) of vegetative cover per land-use polygon. Not to be used in 2D models for FCDMC and not to be used for NDOT without prior authorization.
