Suspended sediment (SS) process can be used to explain reason for geological changes in the coastal area. To understand these processes, we analyzed the relationship between shoreline change and suspended sediment concentration (SSC). Landsat TM/ETM+ images were used for generating the map of suspended sediments concentration and shoreline change in this study. Landsat image has high spatial resolution...
In coastal region, estuaries have dynamic conditions such as river discharge, tidal current, wave and sand ridge. These conditions generate suspended sediments processes in the estuary. Suspended sediment process can be used to explain reason for geological changes in the coastal area. To understand these processes, we use Geostationary Ocean Color Imager to monitor estuarine suspended sediments in...
Coastal shoreline movement due to erosion and deposition is a major concern for coastal zone management. Shoreline changes by natural cause or development constructions. Shoreline change is threatening and destroying living things in the marine environment. Topography of coastal area changes frequently due to a drastic sediment movement. In this study, we monitor the shoreline change and movement...
Spatial relationships between surface sediment distribution and channel networks were estimated for the Ganghwa-Do southern tidal flat, Korea. Tidal channels were extracted from high spatial resolution satellite data and used to derive maps of channel density and distance from channels. The map of surface sediment distribution was produced from grain-size data on sediment samples. Then, for each surface...
The surface sediment distribution in a tidal flat in early 2000s was compared with that of recent years using high spatial resolution remote sensing images and a GIS-based analysis. Maps of the surface sedimentary facies for each timeframe were induced by an IKONOS data acquired in 2001 and a KOMPSAT-2 data acquired in 2008 using an object-based classification method. The spatial relationships between...
The relations of the channel distribution with the sedimentary facies were examined in Geunso-bay tidal flat, Korea. The tidal channel networks were extracted from a high spatial resolution aerial photograph, and for each sedimentary facies, the patterns of the channel distribution were compared in terms of the fractal analysis, channel density and distance from the channel. The channels in each sediment...
