碩士 / 國立中央大學 / 水文與海洋科學研究所 / 106 / This study aims to investigate the seasonal variation of the nearshore currents in the coastal zone of Gunging, Taoyuan city. It has the largest and most complete algal reef along Taoyuan coastal in Taiwan. And the sediment transport is affected by the nearshore current. Then the nearshore current research is most important. In order to understand the seasonal variation of nearshore current, we deployed the Acoustic Doppler Current Profiler (ADCP) in the experimental area once a season, and observed the variation of the current and wave for at least two weeks. We also used the numerical model (Delft3d) to simulate the current velocity and the water level. The previous research has indicated that currents in the Taiwan straits is influenced by the tidal current. Therefore, we discuss the nearshore current of total forcing and the residue current (detide). The calculation of the residue current was computed by the observation data (nearshore current of total forcing) minus the simulation result of the tidal current. The result has shown that (1) It has high correlation between the longshore of nearshore current of total forcing and the tide. But when the northeast monsoon gets strong the effect of longshore is more than the tide. (2) The longshore of residue current is strongly correlated with the along shore wind in the experimental area during the whole year. The longshore of residue current also has high correlated with the radiation stress in fall and winter.
