Breach Initiation and Growth: Physical Processes

During the IMPACT Project a number of large scale field tests were undertaken in Norway to collect data, including extensive video footage, recording the physical processes that occured during the initiation and growth of breach through the test embankments. The video footage has been carefully analysed and key processes identified, to support...

Breach flow discharge prediction - Analysis of USDA breach flow dataset

This report concerns the analysis of flow/discharge measurements obtained from a set of 441 “rigid breach” models constructed between 22/07/1996 and 10/12/1998 at the Agricultural Research Service of the United States Department of Agriculture (USDA) in Stillwater, Oklahoma, US, by G.J. Hanson and colleagues. Each model consisted of a rigid...

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...
