河口的潮能通量和潮能耗散对河口的泥沙输运和地形地貌形成具有重要的参考价值,本文基于FVCOM(finite-volume coastal ocean model)模式研究了辽河口在潮流和径流相互作用下潮能通量和潮能耗散情况。结果表明:辽河口潮能通量最大的区域集中在盖州滩东南侧以及双台子河河口和大辽河口河道急剧缩窄及拐弯处;在两个河口随着径流量的增加,潮能耗散增强,丰水期耗散能量总体上大于平水期和枯水期;在大辽河口,大潮期间的各水期的耗能率约为小潮期间耗能率的两倍;一个潮周期内潮能通量最大值出现在高潮时刻,其值为56.08 KW/m,河流段最大值发生在河道拐角处,低潮时潮能通量最小。潮能通量和耗散的分布的研究结果对于了解辽河口海域的动力过程和河口沉积动力过程方面的研究具有重要意义。
The tidal energy flux and tidal energy dissipation at estuary have important reference value for sediment transport and topography of estuary. Based on FVCOM (finite-volume coastal ocean model) model, the interaction between tidal current and runoff Tide energy and tidal energy dissipation situation. The results show that the areas with the largest tidal energy flux in the Liaohe Estuary are concentrated in the southeast of Gaizhou Beach and the sharp narrowing and turning of the rivers in the Shuangtaizi Estuary and the Dalaisha Estuary. With the increase of runoff, the tidal energy consumption In the Liaohe River estuary, the energy consumption rate of each water period during the tide period is about double the energy consumption rate during the tidal period; the tidal energy flux is the largest during one tidal cycle The value appeared at the climax moment, its value was 56.08 KW / m. The maximum value of the river section occurred at the corner of the river, and the tidal flux was the minimum at low tide. The results of the research on the distribution of tidal energy flux and dissipation are of great significance to understand the dynamic process of estuary and the dynamic process of estuary deposition.
