Field tests of BaNK system were performed in an artificial semi-enclosed beach. We have proposed 'Beach and Navigation Keeper: BaNK system' in order to cope with beach erosion and shoaling of fairway. The system is a method to control sediment transport due to wave-induced residual currents produced by plural submerged asymmetrical structures. In the beach, seashore transformation owing to waves has occurred and been restored every year by a coastal protection work. The transformation of the beach has been investigated on the basis of the field survey from December 2000. Afterwards, half cut old tires as BaNK blocks were set in the beach in 2002 and in 2003 for the tests. As a result of this research, it becomes clear that the BaNK system is very effective as a beach erosion control work in a beach.
