This command divides land-use polylines into closed polylines within a watershed polyline. The closed land-use polylines inside the watershed can then be used to determine the area of each land-use for the watershed. The Curve Numbers & Runoff command has an option to select closed polylines for determining the weighted average curve number from the polyline areas.
