SAND DAM DYNAMIC MONITORING IN COASTAL AREAS BASED ON TIME-SERIES REMOTE SENSING IMAGES

As the development of marine economy and population explosion, coastal areas is suffering great pressure because of the immigration from inland to the developed cities along east China. Island coastal zones, which is a specific ecosystem surrounded by the sea, is more sensitive to human activities, e.g. reclamations. It is essential to monitor the dynamic changes of the island coastal areas to retrieve the siltation pattern of the surrounding open-sea and their impacts to island coastlines using remote sensing technique. In this paper, a time-series monitoring using Landsat images is performed to monitor the changes of a sand dam in the island coast zone, aiming at analyzing the effects of human exploitation. The results show great potential of using remote sensing images for coast zone dynamic monitoring.
