Research Interests

Dr Dongri SONG is currently Professor at Institute of Mountain Hazards and Environment (IMHE), Chinese Academy of Sciences, Chengdu, China. Dr SONG received his PhD (geotechnical engineering) from Hong Kong University of Science and Technology.

His research focus is on the dynamics of debris flow and its related hazards, including (1) effects of solid-fluid interaction on the debris flow (debris avalanche) dynamics; and (2) mechanisms of debris flow (debris avalanche-structure interaction. Through physical experiments (flume and centrifuge modelling), filed monitoring and numerical simulation, the final targets are to develop a physics-based understanding of debris flow and its related hazards and to provide implication to the engineering practice (e.g. new mitigation structures and design guidelines).

Any inquiries on possible research collaborations and consultancy are welcome.
