Abstract: The Platte has changed significantly during the last century. A meandering channel with extensive riparian vegetation growth has replaced, the once braided and unvegetated channel in some reaches. Flow patterns and sediment transport conditions have also changed with the development of reservoirs and irrigation diversions and as periods of drought and high flows occurred. This paper discusses the physical mechanisms influencing channel changes in the Platte and describes an approach for future studies of the geomorphic impact of proposed changes in the flow regime of the Platte.
