The
International Symposium on River Sedimentation (ISRS) is a triennial event
initiated in 1980 by the Chinese Hydraulic Engineering Society (CHES) and
sponsored by the UNESCO. The International Research and Training Center on
Erosion and Sedimentation (IRTCES) in Beijing is the permanent secretariat
of ISRS. Eight symposia of this series have been successfully convened in
seven cities, respectively, namely Beijing (China), Nanjing (China),
Jackson (USA), Karlsruhe (Germany), New Delhi (India), Hongkong (China)
and Cairo (Egypt). Beijing was honored for being accorded the privilege to
host the symposium twice. ISRS has interested more and more hydraulic
engineers and scientists of the world. The Ninth International Symposium
on River Sedimentation will be held at the site of the spectacular Three
Gorges Project in Yichang, China, October 18 to21, 2004. With
the advance in the development of water resources, increasingly more large
hydraulic projects have recently been built in the world. In addition to
such gigantic project as Itape, one may also mention the large Chinese
project of Xiaolangdi on the Yellow River commissioned in the year of 2000
and the colossal Three Gorges Project (TGP) being constructed on the
Yangtze River near the city of Yichang. The latter will be completed in
2009 with the normal pool of its reservoir at 175 m and is potentially the
largest hydraulic project in the world. Presently it has been built to the
extent that the reservoir may be impounded to the level of 135 m, the
installed capacity of power generation has reached an initial value of
5,600 mw and the twin flights of five huge locks each are partially open
to traffic. Large hydraulic projects with large reservoirs on
sediment-laden rivers are bound to interact strongly with the river
systems and thereby to affect their up-and downstream environments as well
as with the riparian environment of their reservoirs through sedimentation
processes involved in flood control, power generation, water supply,
navigation and others. In view of the complexity and importance of these
processes, the following theme is suggested for the 9th ISRS to address: “Interactions between Fluvial Systems and Hydraulic Projects and Pertinent Environmental Impacts”
Under this central theme, six topics are suggested for in-depth discussion, namely, (1) Large-scaled hydraulic projects and their impacts; (2) River sedimentation; (3) Estuarine and coastal engineering; (4) Environmental problems in sedimentation; (5) Soil and water; and (6) Sediment information. The response to the call of papers has been indeed gratifying. More than 500 papers have been received from 52 countries and regions. After reviewing, 390 papers are accepted and printed in the Symposium Proceedings. Encouraged by a large number of contributions from world renowned experts, we are looking forward to a professionally rewarding Conference.
The first ISRS held in Beijing from March
24 to 29, 1980 was the first international meeting organized by the
Chinese Society of Hydraulic Engineering since the founding of New China.
This Symposium was jointly sponsored by the Chinese Society of Hydraulic
Engineering and the Chinese National Committee for the IHP and with the
support of UNESCO.
THE SECOND ISRS (Nanjing, 1983) The second ISRS was held in Nanjing, China, from Oct. 11 to 16, 1983, was another significant gathering of specialists in the field of river sedimentation. Authors presenting papers and participants from Asia, Africa, Europe, North America and Latin America total more than two hundred, including some one hundred from abroad. During he symposium, fellow river engineers, meeting together, reviewed new developments in the research of river sedimentation, exchanged the latest findings and discussed future research needs, thus strengthening the friendship and cooperation between scientists of various countries. Presented in the symposium were 11 general reports and 108 papers covering five major themes in river sedimentation, which aroused immense interest of the participants and brought for the heated discussions. The participants spoke highly of the convocation of international symposia on river sedimentation and expressed the hope of continuing the events of this kind. Many of them suggested and supported the establishment of Standing Secretariat of International Symposium on River Sedimentation in China, which will take charge of the preparation and arrangement of the future symposia. This symposium, sponsored by the Chinese Society of Hydraulic Engineering and the Chinese National Committee of the IHP and supported by the UNESCO and the UNDP, ended successfully. The main topics of the second
ISRS are as follows:
The third ISRS was held in the Ramda Renaissance Hotel in Jackson, Mississippi from March 31 to April 4, 1986. This symposium continues the successful First and Second Symposia held in Beijing, China in 1980 and Nanjing, China in 1983, respectively. The principal sponsors are the Mississippi-Alabama Sea Grant Consortium, the United Nations Educational, Scientific and Cultural Organization and the University of Mississippi. The objective of this series of symposia is to provide scholars, researchers and practitioners with a forum for reporting their latest findings of great importance, reviewing the current state-of the –art, determining the future direction of research, and exchanging ideas and experience in all areas of sedimentation research with emphasis on river sedimentation. The central theme for the Third Symposium is Estuarine and Coastal Sedimentation because of its importance in the region coving the lower Mississippi River Valley and the coast of the Gulf of Mexico. As evidenced by the strong support of researchers around the world as well as national and international professional societies and governmental agencies, there is reason to expect that this series or symposia is to be developed into a major forum with the most comprehensive coverage in all areas of sedimentation research. The central topics for the Symposium are as
follows:
THE FOURTH ISRS (Beijing, 1989) The fourth ISRS was held in Beijing, China from 5 through 9, June 1989. It was jointly organized by the International Research and Training Centre on Erosion and Sedimentation (IRTCES), The Chinese Hydraulic Engineering Society (CHES), and the Chinese Society for Soil and Water Conservation (CSSWC), and co-sponsored by UNESCO, UNDP, IWRA, IAHR, IAHS, CACE and other Chinese relevant agencies. A total of 285 participants attended the symposium. Among them 77 scholars came from 28 countries and regions. The preprinted proceedings in two volumes contained 202 selected papers of nine themes. Overseas and Chinese scholars highly evaluated the success of the 4th ISRS. It strengthened friendship between scholars of various countries, promoted exchange of information and cooperation and proved to be beneficial to all the participants. The central theme for the Fourth Symposium is "Effects of erosion control measures on sediment yield" which is of great importance in the management of watersheds and regulation of rivers. Hopefully this will help bridge the gap between soil conservation and fluvial hydraulics. The central topics for the Symposium are as
follows:
The Fifth ISRS (Karlsruhe, 1992) The 5th ISRS was held from April 6 through 10, 1992, at University of Karlsruhe, Germany. Altogether about 220 engineers and scientists from 38 countries and areas attended this symposium. The Symposium was hosted by the Institute of Hydraulic Structures and Agricultural Engineering, University of Karlsruhe, and sponsored and co-sponsored by IRTCES, IAHR, UNESCO, Germany Research Foundation (DFG), Germany Association for Hydrology and Rural Engineering (DVWK), Federal Ministry of Transportation, Baden-Wurttemberg State Ministry for Science and Art, and Federal Hydraulic Laboratory (BAN). The Central theme of the Symposium was
"Sediment management". The main topics are as follows:
The Sixth ISRS (New Delhi, 1995) The sixth ISRS was held from 7 through 11, in New Delhi, India. Altogether about 150 engineers and scientists from 23 countries and areas attended this symposium. The Symposium was hosted by the Central Board of Irrigation and Power, Government of India, and sponsored and co-sponsored by IRTCES, IAHR.
