A study of using parabolic model to describe wave breaking and wide-angle wave incidence

Up until the present time, there has been little research devoted to applyi ng a time-dependent parabolic model to describe wave breaking and wide-angl e wave incidence. The purpose of this paper is to extend the applicability range of the time-dependent parabolic equation model for both improving the radiation boundary conditions, and including an energy dissipation term in the mild-slope equation. The wave breaking and energy dissipation model wa s examined using experimental data. The comparison indicates that the propo sed model can adequately predict the behavior of wave breaking and energy d issipation in the surf zone. The computational results also show that the p roposed model may improve the conventional treatment of the radiation bound ary conditions for wide-angle wave incidence.
