摘要:
通过黄骅港所在海域的卫星遥感图像分析,揭示了由建筑物引起的沿堤流和环流现象,并对其形成原因进行了初步分析。比较沿堤流和环流形成时的不同水动力和气象条件可以得知,建筑物引起的沿堤流与环流一般是在落潮情况下出现,而且风吹流与波浪沿岸流对沿堤流与环流的形成可能起着十分重要的作用。从泥沙运动的角度而言,沿堤流的作用可能造成黄骅港外航道局部水域含沙量较高,从而造成外航道局部区域的较严重回淤。
The currents along a breakwater and the circulating currents,both induced by the structures in Huanghua Port,are investigated with the help of the satellite remote sensing images and the causes for the formation of these currents are also primarily analyzed.By comparing the different hydrodynamic and meteorological conditions during the formation of the currents along a breakwater and the circulating currents,it can be known that the currents along a breakwater and the circulating currents both resulted from the erected structures appear generally in ebb tides and that the wind-driven currents and the wave-generated longshore currents may play an important role in the development of currents along the breakwater and the circulating currents.From the viewpoing of sediment transport,the currents along the breakwater may result in high sediment concentration in some part of the waterways outside the Port of Huanghua,thus leading to severe siltation in some part of the outer navigational channels of Huanghua Port.
