INTRODUCTION A lagoon surrounded by reefs and islands is a typical topography in South China Sea. Waves in a lagoon...

... periods based on linear wave theory for the assessment of critical excitation frequencies is subject to great uncertainty. It is well established that in model tests and numerical simulations the most severe sloshing loads usually occur at higher excitation periods than predicted critical by simple theory...

... - a product of RAO and random sea state described in this paper by JONSWAP spectrum. Horizontal load comparisons are made for a total of 4 cases of low Ursell numbers in the applicability range of linear wave theory. For the cases considered, the results indicate that in deep waters > 15 m, the computation...

... waved-induced forces. Comparisons between experimental and simulated results are made to analyze the effect of different wave theory applied on the simulation results. Such conclusion can be obtained that when the value of relative water depth is larger than 0.18, linear wave theory is appropriate...

... for the discitization of finite element methods for curved boundaries. The equations have been used to study the interaction between waves and a circular cylinder. Computation shows that the wave run-up around the cylinder from the present method is much greater than that from the linear wave theory, and close...

... The analysis of wave energy converters, including oscillating water columns (OWCs), has traditionally been achieved utilising linear wave theory (Evans 1980). The benefits of using linear wave theory are numerous and significant. In particular, linear wave theory has allowed exact solutions to be produced...

... technique. Although the linear wave theory has been used to describe the transformation f short waves for many areas, it seems desirable to make use of a nonlinear wave theory at least when waves come close to the shore where nonlinear effects become important. Accordingly, this paper surveys...

Stansberg (1990) empirically investigates extreme waves in laboratory generated irregular wave trains. ~Vave superposi- tion based on linear wave theory is used to simulate randomly occurring large waves which are picked out for experimental study. Baldock...

Though the numerical calculation is based on the linear wave theory, it is shown that the present method can evaluate well the wave forces on the cylinders when the wave overtopping was not permitted. The wave overtopping is revealed to reduce the wave forces...

The velocity potential of the incident wave <1>. is given by linear wave theory as shown in Eq.(5), and that of diffracted wave <t>D can be evaluated with the Source...

... be taken into account. Among the past researches of this problem, linear wave theory has been used. But in coastal regions, due to the relatively large wave height to water depth ratio, big error often occurs if linear wave theory is used to describe the real wave profile. Therefore it is needed to study...
