Abstract

The beach erosion control is a serious problem all over the world. Many construction methods of the beach erosion control such as seawall, bulkhead, revetment, beach nourishment, groins, sand bypassing etc. have been considered and studied. The concrete block-type breakwater is an effective work of beach erosion protections. Though it is desirable to have sources of littoral drift and abilities of accretions under normal waves in places where have to control the beach erosion, the beach erosion protection work has been almost constructed after the coast has been eroded by the abnormal waves in reality. The concrete block-type breakwater is able to expect effects of sediment and incident wave control. This paper describes on effect of concrete block-type breakwater obtained from experiments and some implementation examp
