Assessing the impact of seasonal population fluctuation on regional flood risk management

Abstract

This paper focuses on the integration of population and environmental models to address the effect of seasonally varying populations on exposure to flood risk. A spatiotemporal population modelling tool, Population24/7, has been combined with LISFLOOD-FP inundation model outputs for a study area centred on St Austell, Cornwall, UK. Results indicate seasonal cycles in populations and their exposure to flood hazard which are not accounted for in traditional population datasets or flood hazard analyses and which provide potential enhancements to current practice
