(Introduction
to Impervious L-THIA)
Land Use Change Scenarios
Users must identify the current
land use for a specific area, and can describe
up to two land use change scenarios. Users can
select as many land use descriptions as necessary
to describe the current land use or land use
change scenarios.
Users must also describe the
percentage impervious for each land use and
the land use description's size and soil type.
Size can be entered in either acres, square
miles, hectares, or square kilometers. If unknown,
soil types can be determined using the link
below to GIS maps of your region. (Important:
All Scenarios must have the same total area.
The proportions of the total area of the current
land use and each of the land use change scenarios
vary but the total areas must remain equal for
L-THIA to run).
