Abstract

A method to obtain surfable waves by amplifying ship generated waves with both wave concentration structures and a reef is discussed to build surf points in calm areas of nearshore zones. The appropriate wave height for ordinary surfers is defined according to a questionnaire to local surfers in Kagoshima, Japan. The most effective shapes of the structures are determined on the basis of amplification factors of wave height through numerical calculation. We performed hydraulic experiments, as well as numerical computations, of ship generated waves amplified using the structures. Consequently, it is feasible to build a surf point in Kagoshima Bay by amplifying waves generated by the ferries through the proposed method with the structures which consist of the wave concentration structures and the reef.
