EXTREME SOIL STRUCTURE INTERACTION

Currently, the design of physical barriers against debris flows is empirical in nature. The problem with empiricism is that it is not possible to discern whether a design is insufficient, adequate, or over-conservative. More importantly, a transition from empirically-based to scientifically-based design is crucial for enhancing the resiliency of communities in the mountainous regions against geohazards. We are currently looking to reveal fundamental impact mechanisms, to develop analytical approaches and to translate findings to design guidelines that practitioners can use.

EVENT-DRIVEN SENSING AND SMART INFRASTRUCTURE

In an effort to enhance the preparedness and resiliency of communities situated in mountainous regions against Geohazards, engineers and scientists will need to embrace technology such as event-driven sensors and artificial intelligence. By adopting new technology, the processes of managing, reporting, and responding to landslides hazards can be streamlined.

EFFECTS OF CHANGING CLIMATE VARIABLES ON LANDSLIDE DYNAMICS

With global warming, the convective available potential energy, which cause rainfall events, is expected to increase substantially under global warming. According to rainfall records, the frequency of extreme rainfall events that last for several hours is expected to increase. Rainfall will induce region-specific challenges in mountainous areas. One of these critical challenges is dealing with the effects of unprecedented rainfall events on landslides. Also, the recession of glaciers at higher elevations are expected to release sediments and water, which will amplify landslide risks in mountainous regions.

BLUE GEOTECHNICS

We still have only a very limited understanding of what happens under the sea. Answering questions about submarine geomorphology is essential for sustainable offshore development. As development moves offshore, platforms, pipelines, and cables will become more susceptible to landslide hazards. Therefore, improving our understanding of initiation, transportation, and deposition mechanisms of submarine landslides will lead to safe and economical submarine engineering.
