HKIE Geotechnical Paper Award 2022

Our collaborative publication entitled, “Design Recommendations for Single and Dual Debris Flow Barriers with and Without Basal Clearance” as part of the International Consortium of Landslides (ICL), UNESCO, Contribution to Landslide Disaster Risk Reduction book series (CLDRR) has been awarded the Hong Kong Institution of Engineers (HKIE) Geotechnical Paper Award 2022 by the Geotechnical Division Committee (GDC). The award is a biennial exercise. It recognizes the best paper published in any journal or conference in the recent five years that has high potential to advance local practice. The award is selected by a panelist of 16 top geotechnical engineers and researchers in Hong Kong.

The award is presented on 13 May 2022 at the annual geotechnical division seminar organised by the geotechnical division commitee of the HKIE.

Interested research colleagues and students may download the award winning paper for research purposes.
