Study on the Coastal Dynamics and Morphology Evolution Based on Satellite Remote Sensing Imagery

Abstract:

By analyzing a series of LANDSAT satellite remote sensing imageries, the coastal dynamics and morphology evolution features of Shuidong Bay, China were studied. The results showed that the maximum surface suspended sediment concentration (SSC) could exceed 0.1kg/m³ in the interior bay. Within the 5m depth contour, the SSC values range from 0.01kg/m³ to 0.06kg/m³. From the 10m depth contour to the offshore, SSC values are less than 0.01kg/m³. The tidal currents have little contribution to the SSC, and the SSC variation is not significant between seasons. This feature shows that the coastal dynamics is weak, and the sediment transport is not active. Generally, the natural shoreline is relatively stable for coastal areas. However, under the impact of aquaculture reclamations in the bay, in over 30 years the total area of Shuidong Bay decreases by 12.8km².
