The UNESCO-ISI Online Training Workshop on Sediment Transport Measurement and Monitoring took place from July 5-9, 2021, and represents a key initiative of the International Sediment Initiative (ISI) of UNESCO for 2021. It meets the objectives of the new strategy of ISI, which in turn is a contribution to the 8th phase of the IHP (2014-2021), focuses on “Water security: responses to local, regional and global challenges”, and addresses the wide-ranging environmental, social and economic impacts of erosion, sediment transport and sedimentation processes. Measurement and monitoring of sediment transport are of critical importance for managing and mitigating these impacts.
The Online Training Workshop was sponsored by UNESCO-IHP, and the Ministry of Water Resources, P.R. China; organized by the UNESCO-IHP International Sediment Initiative (ISI), the International Research and Training Center on Erosion and Sedimentation (IRTCES), the China Institute of Water Resources and Hydropower Research (IWHR), and the UNESCO Beijing Office; and co-sponsored by the World Association for Sedimentation and Erosion Research (WASER), the International Association for Hydro-Environment Engineering and Research (IAHR), and the Jingjiang Bureau of Hydrology and Water Resources Survey. The workshop had been designed for, and was open to, young engineers, scientists and managers, who were based in developing countries and working in fields such as river basin/reservoir management, water and soil conservation, sediment management and control etc. and who wished to improve their knowledge and understanding of fluvial sediment measurement and monitoring.
A total of 223 participants from 61 countries and regions, including the 15 lecturers/organizers and 208 registered trainee participants, attended the workshop. 176 (85%) of the trainee participants, were from developing countries. The geographic distribution was Asia and the Pacific – 99 (48%), Latin America and the Caribbean – 46 (22%), Africa – 38 (18%), Europe and North America – 21 (10%), and Arab States – 4 (2%). Female participants accounted for 41%.of the total. Over 870 persons including unregistered participants joined in the online training.
The opening of the training workshop on July 5 was chaired by Prof. Manfred Spreafico, Chairman of ISI. Prof. Shahbaz Khan, Director of the UNESCO Office in Beijing and UNESCO Representative to the Democratic People’s Republic of Korea, Japan, Mongolia, People’s Republic of China, and the Republic of Korea; Ms. Xinyang Chi, Deputy Director of the Department of International Cooperation, Science and Technology, Ministry of Water Resource, P.R. China; Prof. Guangquan Liu, Deputy Director of IRTCES; and Mr. Harald Koethe, Director of the International Centre for Water Resources and Global Change (ICWRGC), gave welcome speeches.
Five training lectures and one perspective lecture were delivered over 5 days. The Lectures included:
Lecture-1, Collecting sediment data for studying sediment-based ecological problems (Dr. Mengzhen Xu);
Lecture-2, Sediment Measurement for the Three Gorges Project (Prof. Dr. Guanglei Duan);
Lecture-3, Online monitoring of suspended sediment at the Zhicheng Gauging Station on the Yangtze River (Mr. Dibing Xu);
Lecture-4, Field survey and monitoring methods for river flow, sediment transport and river beds in mountain regions (Dr. Zhiwei Li);
Lecture-5, Measuring erosion and sediment yields on slopes and In small catchments (Prof. Dr. Baoyuan LIU & Dr. Yaxian Hu); and
Perspective Lecture, Measurement and monitoring techniques concerning suspended load and bedload (Prof. Helmut Habersack)
Prof. Manfred Spreafico and Prof. Desmond E. Walling, well-known experts in the field of erosion and sedimentation, served as Chairpersons to chair the lecture and discussion sessions.
The appraisal of the online training workshop by the participants was highly positive. Their assessments indicated that:
‘the presentation was excellent and the topic was very informative’,
‘organized at the highest level’
‘knowledge acquired during the workshop exceeded our expectations’, and
‘we hope more such courses to be organized’.
According to the responses to the questionnaire evaluating the workshop returned by the participants, the assessments relating to the ‘quality of the workshop’ falling into the ‘good’, 'very good’ and ‘excellent’ categories exceeded 94%. Assessments relating to the ‘quality of the documents provided for participants’ falling into these three categories exceeded 97%, and assessments relating to the ‘quality of the training staff/lecturers’ falling into these three categories exceeded 97%.
