Current Projects

Susceptibility of catchments to INTense RAinfall and flooding - SINATRA

SINATRA aims to advance scientific understanding of the drivers, thresholds, and impacts of flooding from intense rainfall in ‘at-risk’ UK catchments and to translate this small-scale process understanding into new open source model architectures and parameterisations to enable the development of decision-support tools, improving the capacity of forecasting agencies to deliver impacts-based warnings and predictions needed for managing Flooding From Intense Rainfall.

Multi-Event Modelling Of Risk & recoverY - FloodMEMORY

The project will look at the most critical flood scenarios caused by sequences or clusters of extreme weather events striking vulnerable systems of flood defences, urban areas, communities and businesses.The project will analyse and simulate situations where a second flood may strike before coastal or river defences have been reinstated after damage, or householders and small businesses are in a vulnerable condition recovering from the first flood. By examining such events and identifying the worst case scenarios, we hope our findings will lead to enhanced flood resilience and better allocation of resources for protection and recovery.
