A NUMERICAL SIMULATION OF WAVE DEFORMATION AND WAVE-INDUCED CURRENT IN SHALLOW WATER REGION BY FUNWAVE
Wave-induced currents drive nearshore transport processes and hence an accurate understanding of wave-current interaction is required for proper management of coastal zone. In the present study, the fully nonlinear Boussinesq model (FUNWAVE) was applied to calculate the wave deformation and wave-induced current in regular wave condition. A sensitivity analysis has been done to find out appropriate values of wave input parameters with the result of various experiments such as Berkhoff et al.’s elliptic shoal (1982) and Watanabe et al.’s detached breakwater (1984). The calculation results show that a strong current forms in the wave direction at the downstream side of the shoal, causing the attenuation of wave height there. In a limited field application, presented model is applied to comparison with data from a barred beach (the DELILAH field experiment at Duck, N.C.) and field data by Sonu (1972). The effect of small alongshore non-uniformities in the bathymetry on the cross-shore distribution of the longshore current velocity is examined. Results from the numerical model on a plane beach are reasonable agreement with the laboratory data of longshore current generated by oblique incident monochromatic waves.
