The 14th International
Symposium on River Sedimentation (14th ISRS) was held in Chengdu, China
from September 16-19, 2019. More than 400 participants from over 25 countries
and regions attended the Symposium. The Symposium was organized by Sichuan University,
sponsored by the International Research and Training Center on Erosion and
Sedimentation (IRTCES) and the World Association for Sedimentation and Erosion
Research (WASER), and co-sponsored by International Association for
Hydro-Environment Engineering and Research (IAHR), National Inland Waterway
Regulation Engineering Research Center, and Changjiang River Scientific
Research Institute, etc.
The opening ceremony was
held in the morning of September 17 and was chaired by Prof. Pengzhi Lin, Secretary
General of the Local Secretariat. Seven welcome speeches were made by Prof.
Weilin Xu, Chairperson of the LOC and Deputy President of Sichuan University;
Mr. Yun Hu, Director General of Department of Water Resources of Sichuan Province;
Prof. Zhaoyin
Wang, President of WASER; Prof. Gary Parker, Vice-President of International
Scientific Committee; Prof. Marcelo H. Garcia, a representative of the
participants; and Mr. Pravin Karki, Global Lead hydropower & Dams at World
Bank.
The 14th ISRS
main theme was ‘Integrated Sediment Management in Rivers and Coasts’ with the
following six main topics:
l Sediment
yield and erosion processes;
l Sediment
transport;
l Sedimentation
in estuarine and coastal areas;
l Reservoir
sedimentation;
l Environmental
and ecological sediment;
l Fluvial
processes and geomorphy;
l Sediment
related to disasters;
l Modeling
& measurement techniques;
l Integrated
sediment management; and
l Fluvial
Processes and Regulation in the Yangtze River.
The programme included 10 plenary
reports, 14 keynote reports, 150 technical presentations in up to 5 parallel
sessions, and 59 poster presentations. The plenary reports were:
l Global trends in water and
sediment fluxes of the world’s large rivers
Prof. Jinren Ni, Peking University, China;
l Non-linear water and sediment
diversions in rivers: a brief history of the Bulle-Effect
Prof. Marcelo H. Garcia, University of Illinois at Urbana-Champaign, USA;
l Cooperation Platform for
Sediment-Related Flash Flood Risk Management
Prof. Xingnian Liu & Prof. Chao Liu, Sichuan University, China;
l Sediment transport and
channel morphology of mountain streams: insights from field observations, flume
experiments and modelling
Prof. Marwan A. Hassan, The University of British Columbia, Canada;
l Mountain River Morphodynamics
in Tectonically Active and Earthquake Prone Regions
Prof. Xudong Fu, Tsinghua University, China;
l Threshold of Particle
Movement: A New Paradigm
Prof. Panayiotis Diplas, Lehigh University, USA;
l Sedimentation Processes in
the Selenga River Fluvial-deltaic System: Assessing the Influences of Grain
Size and Tectonics on Channel Dynamics
Prof. Jeffrey Nittrouer, Rice University, USA;
l Quasi-equilibrium and
equilibrium in fluvial channel geometry: The presence of multiple stable
equilibrium states
Prof. Astrid Blom, Delft University of Technology, the Netherlands;
l Recent flood disasters caused
by river embankment failure in Japan and numerical modelling of embankment
failure
Prof. Hajime Nakagawa, Kyoto University, Japan; and
l Future sedimentation studies
Prof. Zhaoyin Wang, Tsinghua University, China
A half-day technical tours
were arranged on the afternoon of September 18. The participants visited the ancient
Dujiangyan irrigation project, one of the oldest water projects in the world
(2270 years old), which is still working today for flood control and
irrigation, due to its success in dealing with problems caused by sediment
deposition and scour.
During the Symposium, the
Sixth WASER Council Meeting and Assembly were held on September 16 and 19,
respectively. The International Workshop on RESCON 2 and Numerical Modeling for
Assessment of Sediment Management Alternatives were co-organized by the World
Bank, WASER, Sichuan University and UNESCO Office Beijing on September 16.
The closing ceremony was
organized on the afternoon of September 19. Prof. Zhao-Yin Wang, the President
of WASER, chaired the closing ceremony. Prof. Pengzhi Lin from Sichuan
University gave a brief overview for the 14th ISRS. Prof. Guangquan
Liu, the representative of the ISRS permanent Secretariat, announced that the 15th
ISRS will be held in Florence, Italy in 2022 and will be co-organized by the University
of Florence and the University of Padua. Prof. Liu took the symposium banner
from Prof. Pengzhi Lin, representative of the 14th ISRS LOC and
handed it over to Prof. Luca Solari, representative of the next host
Universities. Prof. Solari gave a speech and showed a video to introduce Florence
and to invite and welcome all participants to meet again in Florence in 2022
for the 15th ISRS.
