During the Class A Prediction Symposium on “Debris flow impact forces on single and dual barriers” at The Hong Kong University of Science and Technology, MSc. Yadong Wang and the team from the Institute of Geotechnical Engineering won the Ringo Yu award for the 2nd Runner up.

The Class A Prediction Symposium on “Debris flow impact forces on single and dual barriers” was held at The Hong Kong University of Science and Technology on 8 and 9 May 2022. The aim of this symposium is to advance scientific knowledge and engineering practice in debris flow hazards mitigation.

MSc. Yadong Wang, PhD-student and the team from the Institute of Geotechnical Engineering, Department of Civil Engineering and Natural Hazards, won the Ringo Yu award for the 2nd Runner up in this Class A Prediction Symposium. The prediction contained the following process: first, based on their own SPH codes, the participants focused on the SPH modelling of debris flow impact forces on dual rigid barriers; then the soil-water mixture was regarded as a single-phase material with apparent-viscosity; for the unknown material viscosity, the Mohr-Coulomb rheology model and Bingham model were adopted to capture the fluid-like behaviour, respectively; finally, output the prediction results of front velocity, pressure and impact force on the specific locations of several cells and barriers.

You may have a look at the presentation of MSc. Wang. Please note that two videos (The Evolution of Pressure and The Evolution of Velocity) can be found on the slides.
