How well do the rosgen classification and associated "natural channel design" methods integrate and quantify fluvial processes and channel response?
A. Simon, M. Doyle, M. Kondolf, F.D. Shields Jr., B. Rhoads, G. Grant, F. Fitzpatrick, K. Juracek, M. McPhillips, J. MacBroom
2005, Conference Paper, World Water Congress 2005: Impacts of Global Climate Change - Proceedings of the 2005 World Water and Environmental Resources Congress
Over the past 10 years the Rosgen classification system and its associated methods of "natural channel design" have become synonymous (to many without prior knowledge of the field) with the term "stream restoration" and the science of fluvial geomorphology. Since the mid 1990s, this classification approach has become widely, and...
