The Stormwater Delineation tool processes all features in the specified BatchPoint input feature class and returns the associated Watershed and Watershed Point features.For each input point, the tool delineates the watershed in the following way:Use Direct Surface Contribution Only set to FalseIf the point is on a junction, trace upstream and find the Sink Watershed features associated to each upstream junction as well as to the initial junction.If the point is on a stream, perform a local overland watershed delineation and perform an upstream trace and return the Sink Watershed features associated to the upstream junctions.If the point is on a closed pipe, it is considered as being within the pipe, trace upstream and find the Sink Watershed features associated to each upstream junction In all other cases (land), returns the locally delineated watersed.Use Direct Surface Contribution Only set to TrueIIf the point is on a junction, return the SinkWatershed feature associated to the junction only.If the point is on a stream, perform a local overland watershed delineation only.If the point is on a closed pipe, it is considered as being on the surface outside of the pipe, perform a local overland watershed delineation only.In all other cases (land), returns the locally delineated watersed.

| Parameter | Explanation |
|---|---|
| Input_Batch_Point | Input Batch Point features being processed. The tool will work on a selected set or on all input points if there is no selected set. |
| Snap_Distance | Snap Distance used to determine whether the input point is located on a Junction or on a Open Channel feature. If a snap distance is specified and the point is within the snap distance of a Junction or an Open Channel (if not Junction has been found), then point will be snapped to the Junction or to the closest point on an Open Channel features. |
| Input_Delineation_Type | The tool supports 3 types of delineation: Full Delineation If the point is on a junction, trace upstream and find the Sink Watershed features associated to each upstream junction as well as to the initial junction.If the point is on a stream, perform a local overland watershed delineation and perform an upstream trace and return the Sink Watershed features associated to the upstream junctions. If the point is on a closed pipe, it is considered as being within the pipe, trace upstream and find the Sink Watershed features associated to each upstream junction In all other cases (land), returns the locally delineated watershed. Direct Surface ContributionIf the point is on a junction, return the SinkWatershed feature associated to the junction only. If the point is on a stream, perform a local overland watershed delineation only. If the point is on a closed pipe, it is considered as being on the surface outside of the pipe, perform a local overland watershed delineation only.In all other cases (land), returns the locally delineated watershed. Simulated Inlet Delineation If the point is on a junction, trace upstream and find the Sink Watershed features associated to each upstream junction as well as to the initial junction. If the point is on a stream, perform a local overland watershed delineation and perform an upstream trace and return the Sink Watershed features associated to the upstream junctions. If the point is on a closed pipe, it is considered to be a new inlet, perform a local overland delineation and trace upstream and find the Sink Watershed features associated to each upstream junction In all other cases (land), returns the locally delineated watershed. |
