Class A Prediction Symposium on “Debris flow impact forces on single and dual barriers” was organised by The Centre for Slope Safety in conjunction with the Institute of Mountain Hazards and Environment of the Chinese Academy of Sciences, the Norwegian University of Science and Technology and the Geotechnical Engineering Office of the Civil Engineering and Development Department, Government of Hong Kong SAR. 

The aim of this symposium is to advance scientific knowledge and engineering practice in debris flow hazards mitigation. The symposium was held virtually at The Hong Kong University of Science and Technology on 8th and 9th May 2022.

Participants were provided the details of flume dimensions, barriers, instrumentation and debris properties that would be typically available to a designer. Any predictive tool was allowed for the prediction exercise. Selected winners were given the opportunity to present their predictions in the symposium.
