Course # SPE-0302: June
3-4 2003
Stream Classification - Procedures & Applications
The workshop provides an overview of stream classification systems and detailed instruction in the use of the Rosgen Stream Classification System, the most widely used classification system. The Rosgen classification system offers a number of advantages: it is totally integrated with the fundamental principles of stream morphology presented in Course #1, Fundamental Principles of River Morphology and their applications, and it includes considerable guidance in its application with respect to sensitivity to disturbance, recovery potential, sediment supply, and stream bank erosion potential.
This course is a prerequisite for advanced courses in Stability Assessment and Monitoring. A combination of both lecture and field application are provided.
