碩士 / 國立成功大學 / 水利及海洋工程學系碩博士班 / 94 / ROMS model is applied to understand the characteristic of tidal current in Nan Wan Bay. To get the best setting of time step and horizontal eddy viscosity, the computational stability of the model is carried out first. And then bottom friction coefficient is adjusted by observed data, so as to get the optimal simulation.
The numerical results demonstrate that a counterclockwise eddy and a clockwise eddy exit in the bay everyday, the latter is bigger in size and fills the entire bay. Form lower low water, tidal current passes by the south part of MBT and develops a counterclockwise eddy, until lower high water the current has its maximum. Latter, a clockwise eddy exits in the bay during flood and develop well on the middle of higher high water and lower low water. The tidally-induced averaged current is a clockwise eddy for the most part of the bay and a small size of counterclockwise eddy in the west coast of the bay.
