Abstract


This paper presents a quasi-three dimensional numerical model of wave-induced current due to wave breaking so as to make it applicable to the coastal region with the coastal structures. First, applicability of the present model to undertow velocity and longshore current field was investigated. Secondly, laboratory tests were carried out to examine the characteristics of nearshore currents around the detached breakwater. Thirdly, nearshore currents around the breakwater were computed using the present numerical model. Finally, the results of computation were compared with those of laboratory tests and the applicability of the numerical model was discussed.

Keywords
