Abstract: Eight uninhabited islands of Sixteen Door are located in the Zhoushan sea area with a high-intensity development. Base on the bathymetric data of 1962, 2002 and 2012, GIS technology was applied to analyze the beach scouring and silting in this region. The results indicate that in the past 40 years from 1962 to 2002, the sediment had been silted up in the study area with the rate of 5.3 cm/a. However, it presents an adjustment from slow silting to rapid scouring in the recent decade from 2002 to 2012, with the annual erosion rate of 52.7 cm/a. According to the analysis, since 2002, the combined effects of the intensive human activities in the study area and its vicinity are the main reason for rapid sediment erosion of the underwater slope.

Key words: uninhabited islands, island development, scouring and silting
