Layer: Rivers Strahler Ranking (ID:0)

View In: Map Viewer

Name: Rivers Strahler Ranking

Display Field: rseg_cd

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description:

The first segment of a stream is a 1st order stream. When two 1st order streams merge the next segment becomes a 2nd order stream. When two 2nd order streams merge it becomes a 3rd order stream and so on. However lower order streams joining a higher order stream do not change its order classification.
