| 摘 要： | 运用Mike21模型中的水动力模块对研究区的潮流场进行了模拟,分析研究区的冲淤趋势;利用经验公式,对波浪和潮流进行耦合,计算出极端条件下的最大冲刷深度,对比规划用海实施前后的最大冲刷深度,以对该区域的海岸防护、工程选址等提供科学依据。结果表明:受到填海工程的影响,龙口湾内有轻微淤积,界河至石虎咀近岸海域的波浪和潮流受工程影响而变小,冲刷强度变弱。

Prediction of erosion evolution and deposition in the east coast of the Laizhou Bay after the implemention of the coastal planning |

| Abstract: | In this paper, the hydrodynamic model of Mike21 was used to simulate the flow current, deposition characteristics of the east coast of the Laizhou Bay, to predict its erosion and deposition evolution, Coupling the wave and current, to calculate the limit depth of scouring using empirical formula. By comparing the limit depth of scouring before and after planning reclamation, we found that the Longkou Bay would have a slight deposition. The wave and current of coastal water between the Jiehe River and Shihu area would become smaller and erosion intensity would become weaker, under the influence of engineering. All these analyses have shown that the coastal water between the Jiehe River and Shihu area would change from erosion to deposition when the planning reclamation is implemented. |
