Prof. Ng’s research group was very fortunate to have the company of Prof. Aronne Armanini of the University of Trento (in Italy) for several days in August. Prof. Armanini gave a fascinating seminar, covering topics such as how different types of geophysical flows may be quantifiably differentiated using rheological properties, as well as the governing equations that must be used to describe mixtures of grains and viscous fluids. He also discussed some of the mitigation measures for geophysical flows that are installed in Europe, covering how their effectiveness can be quantified and showing examples of undesirable designs.

Dr SONG Dongri was delighted to be awarded the Ringo Yu Prize for Best PhD Thesis in Geotechnical Studies. (You can read more here.)
The journal paper Back-analysis of geophysical flows using a 3-dimensional runout model has been accepted for publication in the Canadian Geotechnical Journal. The finite-element software package LS-DYNA was used to calculate the internal friction angle of a series of debris flows in Hong Kong. Read the full article here.

Schematic of the modified pressure plate apparatus
The modified pressure plate apparatus is used to study the volume change behaviour of unsaturated soils (Ng et al. 2002). Prior to its development, measurements of the volume change had limited accuracy.
The Géotechnique paper Dry Granular Flow Interaction with Dual-barrier Systems is now available online. Both small-scale flume tests and the finite-element package LS-DYNA were used to understand multiple mechanisms of interaction between flows and dual-barrier systems.
Mr. Stephen Au-Yeung completed his MPhil degree from the Hong Kong University of Science and Technology in 2015. The topic of his MPhil thesis is Flume Investigation of Run-up Mechanisms of Granular and Water Surge Flows Impacting a Rigid Barrier.
Dr. Anthony Gunawan completed his PhD degree from the Hong Kong University of Science and Technology in 2017. His PhD topic was on ultimate and serviceability limit states of floating energy piles in sand.
Dr. Jason Lim Coo obtained his MSc and PhD degrees from the Hong Kong University of Science and Technology in 2012 and 2017, respectively. His doctoral research thesis was on water infiltration into a new three-layer landfill cover system using recycled concrete and nanomaterials.
Dr Soomro graduated with a Bachelor of Engineering from the Quaid-e-Awam University of Engineering Science and Technology in Pakistan with top marks. He later came to HKUST for his doctoral studies and studied the effects of advancing twin tunnels on a pile group.
Dr Wong obtained his doctoral degree at HKUST in 2012. His thesis was on centrifuge modeling of failure modes of tunnels, in both sand and soft clay. He is now Senior Lecturer at the Department of Civil and Construction Engineering at Curtin University in Malaysia.
