苏北沿海挡潮闸闸下水道淤积的因素和影响机制分析

The Analyses of Factors and the Influencing Mechanism of Watercourses Siltation Under Tide-blocking Floodgates in the Coastal Regions in Northern Jiangsu Province

苏北沿海挡潮闸闸下淤积的主要因素有:潮汐、盛行风、水道弯曲程度、上游河道断面、收益区降雨量和围垦。分析这些因素并掌握影响机制,以便适时有效地采取必要的措施,使涵闸更加有效地发挥其工程效益。

The major factors of watercourse siltation under tide-blocking floodgates in the coastal regions in northern Jiangsu province are tide, wind, the curving degree of watercourses, rainfall, and inning. To take necessary measures effectively at the right moment and enable floodgates to exert and their engineering benefit, we must analyze these factors and master their influencing mechanism.
