My research bridges advances in numerical and data analysis techniques with the aim of transforming flood mapping and forecasting to become more automated and flexible for end use, so that we can better mitigate against hazardous events.
Dr Georges Kesserwani
Dr Georges Kesserwani completed his PhD in fluid mechanics at the University of Strasbourg (2005-2008). He went on to a three-year research post in flood modelling at Newcastle University (2008–2011), and joined the Department in 2011. He is presently an EPSRC Fellow holding a prestigious Early Career Fellowship (2018-2022) aiming to deliver the thinking and innovation needed to transform flood forecasting to becoming more automatic and holistic.
Georges’ research provides advanced modelling solutions to various scales of flood risk to forecast environmental change. His mathematical and numerical modelling approaches aim to contribute to better design of resilient infrastructure and to improve our living with flooding. His work crosses the boundaries of many disciplines and activities, with the interface between numerical analysis and hydraulic engineering, and including advances in computational and experimental tools. He has developed a variety of advanced computer models to simulate water and floodplain flows benefiting from collaborations with:
- mathematicians to materialise fundamental concepts in water engineering (e.g. Gerhard et al. 2015, Caviedes-Voullième & Kesserwani 2015),
- experimental researchers to validate these models against experimental data (e.g. Kesserwani et 2010, Rubinato et al. 2017), and
- engineers considering real-scale applications (e.g. Kesserwani & Wang 2014).
