The Rosgen Rosetta Stone: Translating Rosgen Terminology

摘要

David Rosgen's methods for river classification, analysis, and restoration design have been utilized to varying extents all over the United States. A growing body of geomorphic data is being collected by individuals trained in Rosgen methodologies. While this information can be extremely valuable for geomorphic analysis, it can be easily misapplied. Rosgen assigns unique definitions to common terms and uses special methods that differ from the definitions and methods used in traditional geomorphology, hydrology and hydraulics. Researchers and agencies using geomorphic data collected by Rosgen-trained surveyors need to understand what those differences are in order to correctly analyze and use the data. This paper explains terms and procedures involved in the reference-reach survey that may be misunderstood. This paper also suggests simple changes to the Rosgen reference-reach survey that will enhance the usability of the results for a broader range of research and practical applications.
