Description / Table of Contents: Increasingly, gravel-bed rivers are being developed for a variety of purposes: water resources, flood control, land drainage, navigation and power production. It is essential, therefore, that they are sympathetically managed in order to maintain their natural stability and character. This book reports recent research relating to the dynamics of sediment transport, modelling morphological change and the impact of engineering works and catchment development on sediment transport and channel stability. The emphasis on river dynamics reflects the need for a better understanding of adjustment mechanisms in order to develop appropriate mathematical models of channel change for scientific and engineering application. Each section consists of two invited papers which are arranged to form coherent chapters plus shorter discussion papers and a closure by the main authors. Theoretical, laboratory and field studies are included together with applied engineering case studies. The book is based on material presented at the 3rd International Workshop on Gravel-bed Rivers held in Florence in September 1990.
