Current Shore Protection Works in Japan
Keywords:Beach erosion, gentle slope sea dike, wave overtopping, zonal protection works, artificial reef
The function to prevent disaster has been given the most priority in the design of shore protection works in Japan. However, in recent years, the importance of easy access to coasts and waterfronts is increasingly recognized. Therefore, the design of shore protection works requires consideration of coastal scenery and utilization of the beach. To cope with these requirements, new types of shore protection works have been designed and investigated in the field and in laboratories. This paper considers one example of the procedure for the determination of the shore protection works that control beach erosion. Aspects of sea dikes of gentle slope and artificiaI reefs are discussed as two examples of new shore protection works in Japan.
