SENSUM: Smart SENSing of landscapes Undergoing hazardous hydrogeological Movement is £1.2 million project funded by the Natural Environment Research Council (NERC) under its Constructing a Digital Environment programme and is being led by the University of Exeter in collaboration with the Universities of Plymouth and East Anglia.

Floods and landslides affect various parts of the world every year, both inland and along coastlines, causing disruption, occasional fatalities and severe economic loss. An increase in storminess under climate change and population pressure is resulting in an increase in these hazards, as well as threatening the defences put in place to manage them.

Traditionally, landslides and floods have been monitored separately, using a combination of satellite-based remote-sensing techniques and wired ground-based instruments to measure factors such as river flow level, slope displacement and soil moisture.

SENSUM proposes a new integrated way to tackle these hazards, taking advantage of advances in Wireless Sensor Network (WSN) and Internet of Things (IoT) technologies, microelectronics and machine learning.

WSNs show great potential for monitoring and early warning of these hazards. Their main advantage is in the use of easily deployable, low-power sensors that enable continuous, long-term, low-cost monitoring of the environment.

WSNs send and receive data via an internet-based server in real-time, making them part of the growing Internet of Things revolution, in which devices are interconnected and may talk to each other without human intervention.

The Plymouth element of the project is led and coordinated by Dr Irene Manzella, Associate Professor in Engineering Geology and Geohazards, who has designed innovative laboratory experiments which will be carried out using state-of-the-art SOGEES and COAST Laboratory flume facilities at Plymouth.

In this framework, the sensor data on granular flow experiments and debris movement in floods and landslides will be used to provide warnings of instability and hazardous movement as well as to improve mathematical models of these processes.

Finally, 3D visualisation will be developed in collaboration with Associate Professor Digital Art & Technology Dr Andrew Prior based on these novel datasets and enhanced models of landslides and floods and using the University of Plymouth’s unique facilities including the Immersive Vision Theatre (IVT). This dynamic digital hazard visioning is envisaged as a powerful tool for facilitating exchanges between scientists and at-risk populations and ultimately helping to increase preparedness and resilience to landslide and flood risks.

The University team will also involve Post-Doctoral Research Assistant Alessandro Sgarabotto, Professor in Environmental Fluid Mechanics Alison Raby, Associate Professor in Active and Neotectonics Dr Sarah Boulton, Associate Professor in Geological Sciences Dr Martin Stokes and Professor of Geoscience Communication Iain Stewart.
