Watershed Consulting has been hired by the Teton River Conservation District to evaluate six large diversion structures on the Teton River, and to design solutions that would lower annual maintenance of the diversions and thus lessen disturbance to the river. Our analysis and design incorporate both the Rosgen concept of natural stability and our concept of river channel dynamics. Frequency and magnitude of natural channel changes of a high-bedload C4 channel type dictates our approach. Analysis of fluvial landforms, and of riparian successional changes as related to the landforms, illuminates the channel dynamics. A Total Station survey of the diversions allows us to analyze channel geometry and pattern and their departure from an optimum.
Personnel involved: Igor Suchomel - project management, hydrology & hydraulics Steve Buckley - fluvial geomorphology
