  本研究使用美國普林斯頓大學發展的數值模式POM (Princeton Ocean Model) 進行感潮河段的水理計算模式。此模式是屬於三維有限差分的數值模式,適合模擬水深方向物理量變化梯度很大的河口問題。在數值運算方面,分為外模式 (external mode) 和內模式 (internal mode) 兩種不同計算技巧的運用可以大量節省電腦運算時間。另者,由於在河口區存在鹽、淡水混合和鹽水入侵的問題,而POM模式亦可併入鹽度的狀態方程式,即可拿來應用到感潮河段鹽水移動的模式發展。邊界的處理方式則是採用許等人 (2002) 的二維有限元素法模式計算所需的潮位資料,再將其內插至欲計算河口外海處的格網上而獲得。本文亦選擇鹽水溪作為研究之應用對象,計算範圍包含河川及河口附近的海域,同時考慮海洋潮汐及河川流量對感潮河段的影響,完整模擬鹽水溪受感潮影響之水位變化與鹽水移動的情形。
  In this study we use the numerical POM (Princeton Ocean Model) model of the Princeton University to simulate the tidal interaction between ocean waves and the approaching YanShui river. The present three-dimensional finite difference method is found to be quite suitable for simulating the detailed estuary flow behavior, consisting of frequent changes, in the river depth, the local velocity and the pressure gradients, and the salt and fresh water mixing. The two-way simulation process, dealing with calculations of the external mode (e.g., surface elevation and vertically averaged velocity calculations) and the internal mode (updating the flow variables with time and calculating the turbulence effect) saves a lot of computer operation time. On the other hand, the physical mixing/migration process, in the estuary region, of the fresh river water and the salt water from the ocean could be successfully simulated using the POM model. In the simulation process, while at places far away from the estuary region we directly use the tidal data of Hsu et al (2002), near the estuary region we use their interpolated values, as required for a finer grid system. As a direct application, in the present study we simulate the estuary formation with the YanShui river. The computation range contains both the river and the estuary sea area; and the present numerical model successfully takes care of all the associated physical changes in the region, such as, tide formation in the sea region, the discharge of river water to the tidal section of the estuary, and the tidal influence in the sea water level change and the salt water migration to the YanShui river.
