利用二维水动力数学模型模拟海阳人工泻湖潮流运动,并分析了在人工泻湖的西向开通导堤前后泻湖内的潮位变化与水体运动变化过程,据此计算出泻湖内的海水交换率及海水的半更换期。结果表明,在未开通西通道时,泻湖西侧水体的单宽流量在涨急和落急时只有0.66m2/s和0.47m2/s,水体流动缓慢,难以保证泻湖环境生态对水质的需求;当开通西通道时,泻湖内的水体整体运动明显增强,西侧水体的单宽流量在涨急和落急时分别达到1.02m2/s和0.70m2/s,西安路两侧大部分水体能够顺利进行交换,同时泻湖内的水体交换周期也明显缩短,约为2.61d。
The two-dimensional hydrodynamic model was used to simulate the current movement of artificial lagoon in Haiyang. The change of tidal level and water body movement in the lagoon before and after the lava was opened to the west of the artificial lagoon were analyzed. The exchange rates of seawater and seawater Half of the replacement period. The results show that when the West Passage is not opened, the single-wide flow in the west of the lagoon is only 0.66m2 / s and 0.47m2 / s in rising and falling events, and the flow of water body is slow and it is difficult to ensure the water quality of lagoon environment and ecology. When the western passage was opened, the overall movement of water bodies in the lagoon was significantly enhanced. The single-wide flow rate of the water body in the west side reached 1.02m2 / s and 0.70m2 / s respectively during rush hour and rush hour. Most of the water bodies on both sides of Xi’an Road smoothly Exchange, while the lagoon water exchange cycle is also significantly shortened, about 2.61d.
