Zhaoyin Wang and Mengzhen Xu

Zhaoyin WANG (Oct. 1951, Shandong, China) is professor of Tsinghua University and the Chairman of the Advisory Council of the International Research and Training Center on Erosion and Sedimentation (UNESCO). He is president of the World Association of Sedimentation and Erosion Research (WASER). He was elected in 2011 and 2013 as the vice president of IAHR and the chairman of the division of Hydro-environment of IAHR. Dr. Wang was the chief editor of the “International Journal of Sediment Research” from 1996 to 2013. He was one of the initiators of the IAHR journal “International Journal of River Basin Management”. He is associate editor of “Journal of Environmental Informatics”. He is a member of the steering committee of UNESCO International Sedimentation Initiative.

His research interests include sediment transportation, river ecology and integrated river management. He has published 240 odd papers in international journals and international conferences, and published 210 papers in Chinese journals. He is the author of 8 books on sedimentation, integrated river management and ecology. The American Society of Civil Engineers awarded him the 2011 Hans Albert Einstein Award. The award citation reads: ”For his unique contributions for understanding of hyperconcentrated flows, debris flows, watershed vegetation-erosion dynamics, stream ecology and restoration, and integrated river basin management.” In selecting him for this award the selection committee particularly noted significant advances that are currently being used to address the complex environmental erosion and sedimentation in China and all over the world.

Dr. Wang has been invited and delivered 26 keynote lectures and invited lectures at international conferences, including IAHR congresses and symposiums, International Symposia on River Sedimentation, and International Symposium on Eco-hydraulics.


  • Delta development and artificial land creation with sediment

    Sediment is transported to the river mouth and construct the delta. If the ratio of the annual sediment load to the annual water is high and the tidal currents are weak, a male delta develops and the river mouth is moving into the sea. Male delta is unstable and has only one or two channels […]
