河口区泥沙运动受河流水动力、河流来沙、挟沙能力、海洋风浪、潮汐流等多种因素影响,给理论研究和实测带来一定困难。而掌握其运动规律,进而掌握海岸带的冲淤变化,对疏浚河道、海岸工程、码头选址、围垦造田、开发滩涂、发展养殖等有重要意义。遥感技术的崛起,以资料直观、连续和覆盖面积大等特点给研究河口海岸泥沙运动及其冲淤规律提供了一种新的有效方法。
Sediment movement in estuarine area is affected by many factors, such as river hydrodynamics, river sediment, sediment carrying capacity, ocean storm and tidal flow, which bring some difficulties to theoretical research and practical measurement. However, it is of great significance to master the laws of their movement and grasp the changes in the erosion and sedimentation of the coastal zone, which are of great significance to the dredging of river courses, coastal engineering, terminal construction, land reclamation and reclamation, the development of beach beaches, and the development of aquaculture. The rise of remote sensing technology provides a new and effective method to study the sediment movement and its scouring and silting law in estuarine and coastal areas based on the characteristics of direct and continuous data and large area of coverage.
