Land Use
Data
The selection of Data from the Hydrology\Land Use menu is used to add or edit land use
data required for the Sub Basins.
The important values to enter are the Sub Basin ID which must match a Sub Basin ID in
the Sub Basins Table, a land use code, which will come from the Land Use Defaults and
the area for this land use. All of the remaining values can be calculated using the
“Update Data” button.
There are three columns in the Land Use Parameters section of the form. The first
column, ‘Value’, is the value that will be used in the modeling analysis. The second
column, ‘Default’, is the calculated value based on the land use default values. The third
column, ‘Custom’, ensures that a user-entered value will not be overwritten with the
calculated default value when updating data.
Defaults
The selection of Defaults from the Hydrology\Land Use menu is used to add or edit land
use defaults required for the Sub Basins.
