Description 825-832
In view of complex multi-island terrain in
archipelagic sea areas, the paper designs a computational scheme to optimize
computational grid by integrated utilization of water depth data and
high-resolution coastline data with an introduction of topographic
subgrid-scale effect. Numerical tests under the two typical weather conditions
of cold air and typhoon in Ryukyu Islands were conducted using the WAVEWATCH - Ⅲ model.  Results were compared
with measured data.  Results showed that
different computational schemes of complex multi-island terrain were the major
sources of errors of wave numerical simulation in archipelagic sea areas.  Scheme in this paper gave full consideration
to the effect of coastal and multi-island terrain on wave propagation, and
numerical calculation results were obviously improved.
