Dike Risk Assessment
This paper describes the development of a tool, partly based on numerical modelling and partly on the application of the new Eurotop manual. It prioritises coastal structure monitoring by forecasting overtopping discharges and volumes on the different exposed dikes on a low-lying island: “Ile de Ré” (France). The 100 km of coastal protections around this island cover almost all kind of structures that one can imagine. It was a real challenge to apply the new guidance of Eurotop to assess tolerable overtopping, mean overtopping discharge and maximum overtopping volumes.
