Abstract Abstract Zhujiang Water Conservancy Commission of the Ministry of Water Conservancy has monitered dynamically the area of Hekouwan-Lingdingyang of Zhujiang for 13 years with satellite remote sensing data.The satellite image data of 25 temporal of tidal current and water situation from 1973 to 1992 were collected.The dynamic monitoring is mainly for the study of suspended mud and sand content in water at Hekouwan and their distribntion characteristics;the coastline and shoal terrains near the bank and their dynamic change;flowing area characteristics; the projects current situation and change along and near the bank and their affection to water dynamics of river mouth.The satellite remoto sensing images were processed with computer and optical image processing technique,and analyzed according to water dynamics of river mouth and geoscience theory.The analyzed results became the new scientific basis for the planning of Lingding river mouth hamese and project implementation,reasonal usage of resources at shallows,the development and hamess of river courses.Some suggestions have been adopted by operation departments,and brought good social and economical benefits.
