Use the Flow Path Vista to edit flow segments for the catchment area.
A flow path can have up to three flow segments of each flow type. Although the catchment and flow path do not update dynamically based on a surface, you can use the Flow Path Vista to change the surface used to calculate the flow path slope.
- In Toolspace, on the Prospector tab, expand the Catchments collection
<catchment group> <catchment name>. - Right-click a flow path Edit Flow Segments.
- Use the Flow Segments vista to edit the flow path segments.
- Review the calculated Time of Concentration (Tc). If the calculated Tc is less than the minimum required, you can set the Time of Concentration Method for the catchment to a user-defined value by editing the Catchment Properties.
