Online Training: Fundamentals of the Rosgen Stream Classification System

The newest watershed academy online module is now accessible at http://www.epa.gov/watertrain/stream_class/.  The module summarizes the basic Level 1 and Level 2 techniques for classifying stream channel types according to the Rosgen classification system, which is one of the most widely used methods for stream classification in the country. The popularity of this system is due to its basis in fluvial geomorphology and natural stream formative processes, its use of common geomorphic principles and field measurement techniques, its relationship to stability or instability of the stream channel and channel evolution, and relating all of the above to stream restoration principles and practices.
