The volume focuses on the ecological functioning of rivers, which has received less attention than functioning of lakes and reservoirs. The selected papers cover a large range of topics relating to aquatic communities, eutrophication, nutrient dynamics and organic pollution, erosion and sediment transport, and fate of micropollutants at the basin scale. Integrated approaches developed in order to study the ecological functioning of fluvial systems perturbed by human activity are presented. This functioning is analysed from the point of view of fundamental research, but insights into system management are not neglected. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, and water surface pollution, to postgraduate students, to the institutions involved in water resource management, and to the drinking water and waste water treatment industries. It draws information from many large river systems in the world.
