| 摘 要： | 利用韩江河口近20多a的卫星影像资料，结合GIS技术，通过对韩江河口流势、流态和水沙输移特征的分析，探讨韩江河口
出口水流动力状况及其对泥沙输移的影响。结果表明，韩江河口区内泥沙含量较低，在河口区内涨落潮流呈西南-东北向运动，在
河口外则易受西南沿岸流影响，具有近岸输沙的特性。

| Abstract: | Based on an analysis of characteristics of sediment transportation and flow field in sea areas of
Hanjiang estuary by using the multi-temporal landsat image, this paper deals with the hydrodynamic condition of
Hanjiang estuary and its impacts on sediment transportation. Some conclusions have been reached: ①Sediment
concentration in the Hanjiang estuary is low; ②In the estuary, the tidal current runs from southwest to
northeast; ③ Outside of the estuary, the flow from the Hanjiang river is affected by the southwest current, and
the suspended sediments are transported along the boundary. |
