Loughborough University drone expert develops tech for climate change tracking


A Loughborough University academic is developing drone technology to measure the size of small, underwater sediments in a bid to understand how rivers are responding to environmental drivers such as climate change.

Physical geographer Dr Amy Woodget of the School of Social Sciences, is hoping her research using drone imagery and machine learning will allow sediments as small as 0.5cm to be measured accurately, providing valuable scientific data that will reveal how rivers are behaving.

By studying patterns of sediment size, experts can understand changes that are occurring in rivers as a result of environmental factors.

Dr Woodget says drones allow for environments to be studied in much more detail than previously possible and it is likely to become very important for helping make the right decisions to manage environments effectively.

She explained: “This research project aims to measure the size of underwater river sediments using a novel technological approach using drone imagery and machine learning.

“We need to know how to accurately measure underwater sediment sizes in fine detail in order to improve our understanding of how rivers and their resident animal and plant life are changing and responding to big environmental drivers like climate change.

Adding: “Using drones is a bit like the difference between driving with your glasses on instead of off, if you’re short-sighted. The detail revealed by wearing the glasses – or in this case from the detailed drone imagery – helps us make better decisions to ensure our safety and that of others.”

“So, this means that if we care about our economies, homes, industries, agriculture, transport networks, recreational and environmental spaces and how they might be threatened by climate change, then we need to be able to measure and monitor physical parameters like sediment size accurately and with our glasses on,” she continued.

Dr Woodget will undertake fieldwork at two river sites – in the Lake District and along the England-Wales border – which both experienced serious flooding in 2015 as a result of Storm Desmond.

Her research project is funded by the British Sedimentological Research Group and is expected to run for up to two years.
