| 1 | Sediment loads and processes in large rivers显示文摘The pressure and impact on large rivers have increased greatly in recent years,as a consequence of their exploitation to meet various human needs.Large rivers are particularly exposed to problems of multiple uses,often with conflicting aims.At the global scale river systems are increasingly altered by dams,leading to interruption of continuity and a disrupted sediment regime,which results in far-reaching problems.These challenges point also to the need for more integrated management approaches and consideration of catchment-river interactions emphasizing land use management and effects of these uses.At the global scale,there is currently no overview assessment of the current status of the world’s large rivers,the conflicting demands on such rivers,and likely future anthropogenic impacts,as well as the potential for restoration,improvements in integrated management and the associated problems caused by their multiple uses.The special issue in the International Journal of Sediment Research on'Sediment loads and processes in large rivers'aims to provide a global forum for a wide-ranging discussion of key issues related to research on large rivers and to their effective and sustainable management,involving both scientists and decision makers.The sequence of papers in the special issue highlights the current situation in different river systems with regard to morphodynamic reactions | Helmut HABERSACK Daniel HASPEL | 2013 | International Journal of Sediment Research2013，28，4： | 0 |
