Maral is developing a system that combines satellite data with
artificial intelligence to warn authorities when large scale physical
structures, such as dams, are on the brink of collapse. In the mining
industry, a type of dam called a tailings dam is used to store mine
waste, many of which are toxic. Maral is using tailings dams as an
exemplar for her work because these structures are extremely prone to
failure, causing the loss of human life and irreparable environmental
damage, in addition to billions of dollars in losses every year. There
is an urgent need to make these dams safer through improved monitoring
and better early warning systems.
From hundreds of km in space, satellite-Interferometric
Synthetic-Aperture Radar (InSAR) analysis allow detection of ground
motion to a high level of precision. However, complexities in converting
the raw data to actionable information has so far limited authorities’
ability to practically monitor these structures from space.
To help solve this, Maral is creating a framework for geotechnical
validation of the satellite measurements by developing 3D numerical
models capable of simulating the underpinning mechanics of the observed
soil movements. From this, she will create deep learning experiments to
create an end-to-end scalable early warning tool, tested on historical
failures and other geotechnical applications.
Maral works as an
Earth Observation Specialist at the Satellite Applications Catapult,
which has given her the opportunity to work with mining engineers and
environmental agencies in Peru and Brazil, and inspired this work. She
previously worked as a Remote Sensing Analyst at Airbus Defence and
Space, developing innovative applications of satellite data. Maral holds
a masters in geology from University of Bristol.
