Globally, floods cause thousands of fatalities and billions of Euros of damage per year. Hence, several global models have been developed to assess the impacts of either river or coastal floods. However, the socioeconomic impacts of flooding in deltas and estuaries are even worse when river and coastal floods coincide, such as during Hurricane Harvey in 2017 and the devastating floods in Thailand in 2011. Since current global flood risk models assess either river or coastal flood processes, they cannot be used to examine the influence of such compound river and coastal flood processes on flood risk. The proposed research fills this knowledge gap. The main objective is to improve our understanding of compound flooding in delta areas and its influence on flood risk. To this end a globally applicable nested flood model will be developed. This model will be used to to understand the effect of compound floods on total flood risk and to characterize compound floods and their meteorological drivers.
We provide a disciplinary and multidisciplinary research programme aimed at advanced understanding of environmental problems and advanced training of PhD candidates in this field.
