碩士 / 國立臺灣海洋大學 / 河海工程學系 / 103 / Taiwan is a major hub in the maritime transport of the Asia–Pacific region. Its development primarily depends on international trade and maritime transport. Currently, Taiwan’s main international commercial ports are the Port of Keelung, Port of Taipei, Port of Taichung, Port of Kaohsiung, and Port of Hualien. To integrate the increasingly active development of international trade, the competitiveness of port facilities must be enahnced rapidly; thus, maintenance and updates are primary objectives. The Port of Taipei is an entirely artificial harbor and the port’s phased development plan will change the original coastal flow characteristics. In addition, because of its proximity to the Tamsui River, a large amount of river sediment will also be affected. The flow field changes around Port of Taipei and the Tamsui River estuary area must be understood to avoid coastal topography changes influencing the safety of the fairway.
This study used the DHI MIKE-21 Hydrodynamic Model and a Particle Tracking Model to conduct numerical simulations. In the simulation, virtual buoys in the Port of Taipei ocean area were cast and recovered at different times. The simulated paths by virtual buoys were verified according to the measured values to obtain the area flow-field characteristics during the various construction phases and facilitate establishing the trends in future flow-field changes, which can provide a reference for subsequent port spatial planning.
The study results show that the particle movement path was from north to south during high tide until the low tide arrived; subsequently, the particle path moved in the opposite direction. Over time, however, the particles tended to move south. In phases two and three of the port construction, the particles were influenced by near-structure eddy currents, causing them to concentrate mostly on the south side of the port. The particle movement paths of long-term construction were all in an offshore direction from the port.
