dc.description.abstract | The southern tidal flat of Kanghwa Island with an area of approximately 90 km2 is one of the biggest flats on the west coast of Korea. Remote sensing has the potential to provide synoptic information of intertidal environments. To estimate quantitatively the morphologic change in a tidal flat, it is necessary to measure both the amount of sedimentation or erosion and the sediment facies involved. The objectives of this study are : (i) to generate an intertidal digital elevation model (DEM) using the waterline method around 1989; (ii) to quantitatively estimate morphologic change from the generated DEM for the years 1989 and the extracted waterlines for the years 2002; (iii) to discriminate the surface sedimentary facies by texture analysis and classification method using high-resolution satellite data such as IKONOS and Kompsat EOC; iv) to ultimately evaluate the morphologic change with respect to sedimentary facies. The morphologic change is dependent upon the sedimentary facie. The changes in sand or mixed flats are greater by at least three times than the changes in the mud flats. Although we are not able to evaluate the accuracy of the morphologic changes estimate, the resulting trend of sedimentation or erosion complied with the general rule of sedimentology. The results demonstrate that satellite remote sensing is an efficient and effective tool for a long term morphologic change estimation in tidal flats. | - |
