Sea dikes breaching initiated by breaking wave impacts - Preliminary computational model

Sea dikes are of crucial importance in the defence systems of low-lying coastal areas in Germany as well as in other countries such as The Netherlands and Denmark. Breaches of sea dikes due to storm surges are regarded as the main cause of flood disasters, so that a reliable prediction of both breach initiation, breach formation and breach...

Hydraulic model tests on breaching with and without waves

This report describes small-scaled experiments performed at Leichtweiß-Institute for Hydraulic Engineering and Water Resources, Technical University Braunschweig (LWI). The experiments have been conducted to investigate the development of dike breaches in homogeneous sand dikes with and without a clay layer. The used scaling factor was 1:10.The...

Sea dikes breaching initiated by breaking wave impacts - State of the art

Sea dikes are of crucial importance in the defence systems of low-lying coastal areas in countries such as Germany, The Netherlands or Denmark, etc. Breaches of sea dikes induced by storm surges are regarded as the main cause of coastal flood disasters. Therefore a reliable prediction of both initial conditions for the breach occurrence and the...

Sea dikes breaching initiated by breaking wave impact - Detail computational model

Sea dikes are of crucial importance in the defence systems of low-lying coastal areas in Germany as well as in other countries such as The Netherlands and Denmark. Breaches of sea dikes due to storm surges are regarded as the main cause of flood disasters, so that a reliable prediction of both breach initiation, breach formation and breach...

Laboratory Tests on the Erosion of Clay Revetment of Sea Dike With and Without a Grass Cover Induced by Breaking Wave Impact

This report addresses the preparation and performance of laboratory tests on a the erodibility of clay cover with and without grass, subjected to impact pressures generated by controlled falling water mass Three types of clay, representing different erosion resistances as well as grass cover of moderate quality have been used in order to gain...

Breaching of coastal dikes: State of the art

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...
