International Symposia on River Sedimentation (ISRS)


The International Symposium on River Sedimentation (ISRS) is a triennial event initiated in 1980 by the Chinese Hydraulic Engineering Society (CHES) with the support of UNESCO. The objective of ISRS is to provide a forum for scientist, engineers, researchers and decision makers to exchange ideas, research results, advanced techniques, and to share their experiences and information on sediment study and management.The International Research and Training Center on Erosion and Sedimentation (IRTCES) in Beijing is the permanent secretariat of ISRS. The WASER was inaugurated at the 9th ISRS in 2004, and the ISRS has been served as the official symposia of WASER since then.
