Flood impact and risk assessment for urban city Ghent

Abstract
Previous studies have reported that Ghent (Belgium) and regions nearby are insufficiently protected against storm surge events from the North Sea, whether combined with high upper drainage by abundant rainfall or not. When a downpour occurs and drains can no longer effectively manage the amount of water, floods in and around the city of Ghent will cause damage to energy and transportation infrastructure and precipitate a disruption to the delivery of services. In this research, an analysis is made for the casualties and economic damage caused by floods due to a downpour that statistically takes place once every twenty, fifty, and hundred years (T20, T50, T100) for the current situation and for the projected situation in 2050. The impact of moderate to extreme floods in the territory of Ghent is investigated, wherein all fragile infrastructure and vulnerable functions are identified and described. Although Ghent appears to be well protected against the high water levels of the rivers Lys and Scheldt, the complex system of drains and canals in and around Ghent is nevertheless insufficient for the downpour of type T50 and T100. This research concludes with an adaptation plan with a series of practical measures to be introduced by 2050, e.g., inserting gates where needed, building sluices to prevent ingress of water into drains, raising floor levels in vulnerable town centre properties, and installing breakwaters. This local-scale assessment is a step towards helping the community to understand coastal flood events and how they might change with sea level rise and storm surge events.
