This is the first interdisciplinary book on the mobilization of nutrients and pollutants in the water phase due to hydrodynamic processes. In its ten chapters, a broad set of practical process knowledge is presented, comprising simulation techniques, laboratory and in-situ studies on the interaction between biological, chemical and hydrodynamic factors as well as models, for solving combined quality and quantity problems of riverine sediments both on local and and river basin scales. These papers result from an International Symposium on Sediment Dynamics and Pollutant Mobility in River Basins, held in Hamburg, March 26 to 29, 2006.
