Force Downstream Flow
Force Downstream Flow tool modifies the elevation values of vertices of linear elements to enforce a consistent slope direction down for the linear element. The tool is useful to ensure that water stream breaklines run down all the time without small upward changes. The tool only modifies elevations of vertices if this is required to enforce the consistent downward direction.
To enforce that linear element(s) go down consistently:
1. Select the Force Downstream Flow tool.
2. Identify the element with a data click.
3. Accept the element selection with another data click.
This modifies the elevation values of the vertices of the selected linear element.
OR
1. Select linear element(s).
2. Select the Force Downstream Flow tool.
3. Accept the selected element(s) with a data click.
This modifies the elevation values of the vertices of all selected elements.
