River Confluences, Tributaries and the Fluvial Network brings together state-of-the-art thinking on confluence dynamics tributary impacts and the links between processes at these scales and river network functions. Taking a global approach, this multiauthored text features a team of carefully selected, internationally renowned experts who have all contributed significantly to recent groundbreaking advances in the field. The book is unique in focus, content, scopeand in bringing together engineering, ecological and geomorphological approaches to the three key areas of river system science.
