| 摘 要： | 海岸工程实施后,将会改变区域地形,并对该区域的水动力及泥沙冲淤产生影响。针对潮间带特点,将淹没水深和淹没流速代入半经验半理论公式中,预测强潮浅水海区泥沙冲淤变化。在平面二维潮流模型的基础上,应用修正后的半经验半理论公式,计算分析漩门湾围垦工程对潮间带泥沙冲淤变化影响。

| Abstract: | The implementation of coastal engineering will change the regional terrain and affect the hydrodynamic forces and sediment transportation.According to the characteristics of the intertidal zone,using semi-empirical Semi-theoretical formula with submerged depth and submerged velocity,we predicted the sediment scouring and silting within the intertidal zone.Base on the 2-D numerical model for the tidal current,and used the modified semi-empirical Semi-theoretical formula,we analyzed the influence from the rec... |
