 Abstract

Coastal dikes are used as defence structures against flooding in lowland areas and where high tidal ranges occur. The development of a breach induced by wave overtopping has been one of the most frequent causes of dike failure and it is closely related both to the dynamics of a protected coast and to the flood risk assessment and management. At present however, the underlying processes, their simulation and prediction are still not well understood. Due to the urgent need of reliable simulations of the processes, the requirements for a new model were defined. This study, started in 2004 and taking 3 years, is supported by the Joined Doctoral Programme on “Risk Management on Built Environment” (Study University of Florence, Italy and Technical University of Braunschweig, Germany)* and by the European Integrated Research Project FLOODsite (2002- 2006). In this report the processes associated with breaching and the present capability of breach modelling are reviewed. A detailed specification of the new model approach is then proposed.
