WMS:Drainage Module Menus

The Arcs->Outlets command in the DEM menu of the Drainage module will automatically place a new outlet feature point at all intersections of a selected arc (required input to the command) and the specified flow accumulation value. The default flow accumulation threshold will correspond to the current display options setting and represents the area upstream. This is particularly useful if you wish to establish outlets for a series of drainages that a highway or other important line feature will cross as illustrated in the figure below.

Outlets created with the Arcs->Outlets command

The arc should exist in a drainage coverage or the nodes created by the intersection will be generic nodes rather than drainage outlets.
