When a flow path is initially created, it is created with the number of flow segments defined in the Catchment Settings. The Create Flow Segments command enables you to divide a flow path into more segments.
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.
