遥感及地理信息系统技术在海岸动力研究领域和工程规划设计方面的应用前景十分广阔。本文介绍了将这两种技术结合起来用于测量潮汐水道及湖滩水深，计算和分析淤泥质潮滩冲淤演变过程的方法，其测量手段的科学性、先进性，计算的精确性和模拟显示的直观性，都是以往方法无法比拟的。文章还以长江口南支和舟山两地研究的成果介绍了这一技术的应用情况。相信这一技术在海岸带开发利用以及近海工程、航运、水利、环保等方面都具有很大的社会效益和经济效益。

The technology of remote sensing and geographical information system has a vast vistas in the fields of the investigation of coastal dynamics and the engineering planning and design. In this paper, the combination of such technology is applied to survey tile tideway and water depth of tidal flat, calculate and analyze the scour and fill process in tidal flat. The scientificalness and advantage in survey means, the accuracy in calculation, and the visualization in simulation are incomparable. Such technology. seeing the investigation achievements for the south branch at the Yangtze estuary and the Zhoushan, has a significant social and economical efficiency in developing coastal zones, coastal engineering, shipping, water conservaney and environmental protection.
