| Abstract: | Based on a three dimensional and high resolution numerical model, some factors associated with the marginal seas adjacent to eastern China (including the Bohai, Yellow and Eastern China Seas), such as the Coriolis acceleration, tide amplitude and phase on the outer boundary, seabed topography, coastline configuartion, and frictional coefficient are studied with the aid of Geographic Information System (GIS) in order to understand the respective impact of these factors upon the tidal wave system. According to the present study, moderate changes in the tide amplitude and phase on the outer boundary, the seabed topography and the frictional coefficient has little effect on the tidal wave system. However, the transformation of coastline configuration has remarkable consequences within the tidal system, and so does the tremendous changes of the seabed topography. Since in reality the input data of tide amplitude and phase, the Coriolis acceleration, the seabed topography and frictional coefficient are comparatively stable, the tidal wave system in the marginal seas adjacent to eastern China is a combined result of tide and marine environment. The marine conditions, especially the coastline configuration, are the predominated factors affecting the tidal-wave system. In a sense, the tidal amphidroms and tidal amphidromic system are controlled mainly by the coastline configuration over this region. |
