International symposium on river sedimentation

International Symposium on River Sedimentation , launched in 1980, with the permanent secretariat located in the International Research and Training Center on Erosion and Sedimentation, became a series of meetings of the World Association for sedimentation and Erosion Research (WASER) in 2004. With the support from the United Nations Educational, Scientific and Cultural Organization and related international academic community and under the active participation of experts and scholars in many countries, this symposium has become an important and influential international meetings, and has been raising worldwide attention and participation of more and more scholars and experts.
