Dear Colleagues,

As you know, the 15th International Symposium on River Sedimentation (15th ISRS) will be held in Florence, Italy from September 6-9, 2022 and we are looking forward to meeting with you there. Although it is a long way ahead, there is now a need to begin thinking about the arrangements for the 16th ISRS, which is scheduled to be held in 2025.

Let’s briefly review the origin and development of the International Symposium on River Sedimentation (ISRS) conference series. The series of triennial conferences was initiated in 1980 by the Chinese Hydraulic Engineering Society with the support of UNESCO. Since its foundation, the International Research and Training Center on Erosion and Sedimentation (IRTCES) in Beijing has served as the permanent secretariat of ISRS. Fourteen such symposia have been successfully held in China (5 times), USA, Germany (Twice), India, Egypt, Hong Kong China, Russia, South Africa, and Japan. The World Association for Sedimentation and Erosion Research (WASER) was inaugurated at the 9th ISRS in 2004 with its Secretariat located in the IRTCES, and the ISRS has since then become the official Symposium of WASER. The objective of ISRS is to provide a forum for scientists, engineers, researchers and decision makers to exchange ideas, research results, and advanced techniques and to share their experiences and information, across the broad field of sediment and its management.

IRTCES and WASER are currently beginning the process of establishing the venue for the 16th ISRS. The venue and organizer will be announced in Florence in 2022. Several universities and institutes have already expressed their interest in hosting the 16th ISRS. We would welcome more proposals for hosting the 16th ISRS in 2025. Please submit your proposals to Prof. Zhaoyin Wang, President of WASER, and Prof. Guangquan Liu, Secretary-General of WASER and Deputy Director of IRTCES (see addresses below) before March 31, 2022. The final decision on the venue and organizer will be made jointly by the permanent secretariat of ISRS (IRTCES) and WASER.

We look forward to hearing from you.

Sincerely yours,
