Classify stream reach using the descriptions and key as shown in Figure 14 and Figure 15.
The field data is recorded in the worksheet form, Worksheet 12. (PDF, 29 kb, 1 p.) A summary treatment of the field methods and examples for stream classification are shown in Fundamentals of the Rosgen Stream Classification System module of the Watershed Academy. Detailed descriptions of the classification methods and field forms are shown in Chapters 4 and 5 of Applied River Morphology (Rosgen 1996) and the Reference Reach Field Book (Leopold et al, 1998).
