Internationally renowned experts in geography and fluid dynamics visited DDFORS

Date:Mar 31, 2023

    A group of six international experts in the fields of geography and fluid dynamics visited the DDFORS from July 28th to 31st, 2017. The purpose of their visit, was to accelerate the research progress of the US National Science Foundation's international collaboration project titled "Debris Flows: Influences on Natural Resources and Hazard Mitigation under a Changing Climate." The visiting experts included Professor Alexander Densmore from University of Durham in UK, Professor Kimberly Hill from University of Minnesota Twin Cities in US, Professor Qicheng Sun from Tsinghua University, and Professor Tao Zhao from Sichuan University.

   During their visit, the experts, accompanied by Deputy Director Gordon G. D. Zhou, inspected the landslide and debris flow areas of Jiangjia Ravine, the erosion of the channel in the deposition area, as well as the geological and hydrological processes in the basin. They also carefully inspected the engineering measures in Dongchuan City.

   The two scholars from University of Durham and University of Minnesota Twin Cities shared their latest research findings in the forefront areas of debris flow deposition landforms and particle flow erosion mechanisms, while scientists in DDFORS introduced their research progress in debris flow dynamics, prevention and control engineering, interaction mechanisms, numerical simulation and risk analysis, and early warning systems. The exciting academic exchange attracted more than 30 researchers and graduate students from institutions such as the Beijing Forestry University, Fujian Agriculture and Forestry University, Henan University of Science and Technology, and Chengdu University of Information Technology, who were conducting experiments and observations at the DDFORS.

   Both sides also held in-depth discussions on joint applications for the next international cooperation projects, promotion and application of research results, joint development of experimental equipment, and they expressed the hope to maintain close contact to jointly plan and construct a large-scale debris flow dynamics simulation experiment system and observe the whole process of the debris flow in Jiangjia Ravine, thus promoting the disciplinary level and academic influence of surface process research.

   Finally, based on the project of "Debris Flows: Influences on Natural Resources and Hazard Mitigation under a Changing Climate", they decided to conduct field debris flow experiments in the upstream Menqian Gully (a sub-branch of Jiangjia Ravine).
