ABSTRACT

In this study, the geographical and geomorphological changes as well as the change of land scenery for about 100 years from the Japanese occupation period to the present in terms of Buyeo area have been attempted to be analyzed with time series using terrain analysis and GIS analysis. The result of analysis is as follows. The alluvial island distribution within the river channel formed by Geumgang and its scale have been clarified as most typically shown. Especially, the alluvial island verified in section III has been verified as the greatest scale for about 100 years in the investigation area. Seen based on the alluvial island area of the Japanese occupation period, the area of alluvial island in 1960’s, 1970’s, 1980’s, 1990’s, 2000’s and 2010’s have been reduced by about 78%, about 59%, about 59%, about 83%, about 90% and about 91%, respectively. Also, the alluvial island of IV section during the Japanese occupation period became extinct in 1960’s and new alluvial island was formed. This alluvial island becomes completely extinct starting 2000’s. With the current stage, the factor causing creation and extinction of previously mentioned alluvial island is uncertain.
