The 15th ISRS is postponed to September 5-8, 2023

The 15th International Symposium on River Sedimentation (15th ISRS) to be held in Florence, Italy in 2022 has been postponed by one year to September 5-8, 2023 due to COVID-19. The new date was suggested by the Local Organizing Committee, considering feedback from WASER Council members, and was approved by WASER and IRTCES.

The ISRS 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 at venues 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 based in IRTCES, and the ISRS has since then become the official Symposium of WASER and has included the WASER General Assembly. The objective of the 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 experience and information, across the broad field of sediment and its management.

The theme of 15th ISRS is ‘Sustainable Sediment Management in a changing Environment’ with 10 topics including: Sediment transport, Reservoir sedimentation, River morphodynamics, Coastal morphodynamics, Ecomorphodynamics, Sediment related disaster, Plastic in river and coastal systems, Interaction between sediment dynamics and hydraulic structures, Integrated sediment management at the river basin scale, and Social, economic & political problems related to sediment and water management.
