Melanie Bettles

Bio:

I have a strong interest in geo-hazards and how these interact and impact people, infrastructure and the natural environment. My BSc dissertation focused on exposure to earthquakes in New Zealand, and my MSc in Geophysical hazards allowed me to explore a variety of hazards, with a focus on volcanic debris flows in my research project. Outside of my studies, I’ve led backcountry hiking trips in a US summer camp, allowing me to share my love of the outdoors with young adults.

 

Project overview:

Debris flows are a significant global hazard threatening people, the environment, and infrastructure. Under a warming climate, debris flows are expected to become more frequent with increased intensity and frequency of precipitation events. Debris flows are distributed globally; however, some regions are more susceptible than others, with the hazards often being repeat events. The risk in these areas can be focused on the debris flow fans and their torrents. These features are morphologically distinctive and can be identified using geomorphic metrics derived from open-source global DEMS. Current research is often limited to known debris flow sites at a local level.

This project aims to assess potential debris flow runouts and catchments using topographic metrics and morphometric parameters from DEMs and remote sensing data. This will identify susceptible catchments and fans and identify key areas at risk. Debris flow modelling and field work will then be completed at the key catchments to validate the remote sensing data and investigate the exposure and vulnerability in the catchments.
