| Summary | Published in June 2003 IOT SERIAL No.92-86-765，262pp. This study is the third part of a series of studies of the tidal current simulation on seas surrounding Taiwan. In the previous studies, resonance of tides induced mainly by the semidiurnal constituents and the oscillation pattern appearing as partially standing waves has been demonstrated based on the predominant effects of the Asia Continental Shelf. The Kee-Lung Port is located right next to one of the nodes of the partially standing tides therefore, the main purpose of present study is to apply the related numerical results to further investigate the local characteristics of tides and tidal currents on sea surrounding the north coast of Taiwan as well as around the Kee-Lung Port. The bathymetry was set up using the coastal relief database ETOPO5, downloaded from the National Geophysical Data Center (NGDC), USA. Based on the two-dimensional depth-integrated shallow water waves equations, the nested grid scheme was adapted, and the MIKE21_HD model, developed by Danish Hydraulic Institute, was applied. The computation results indicated that even though the local characteristics of tides around the Kee-Lung Port were hard to simulate because the bathymetry precision was too coarse to well describe the topographical effects of the Asia Continental Shelf, the computation tidal currents corresponded those of the measurements. With the excellent validations, the computation currents were then further applied to assess the capacity of sediment transport around the coats of Taiwan and to track the deposition sites of floating woods and garbage that were flushed into the sea after the attacks of typhoons. Consistency was also achieved as compared to the field surveys. |
