WMS:Define Upstream Channel
The Define Upstream Channel step is used to define an arc representing the upstream channel.
Help
This dialog functions similar to the step in which the tailwater channel was defined. When an arc is defined (arcs must be created from upstream to downstream) from this step in the wizard, their attribute is set to the HY-8 upstream arc attribute type. This arc is used when delineating the floodplain from the culvert headwater data in the next step of the wizard.
Define upstream centerline – This button allows creating arcs that represent the upstream centerline.
Select upstream centerline – This button allows selecting arcs that represent the upstream centerline.
Delete upstream centerline – By selecting this and then clicking on an arc to delete an upstream centerline.
