ABSTRACT

Geomorphological map is the map showing the landforms classified by the geomorphic knowledge, spatial distribution of the specific forms and forming material, transporting routes of material, chronology of the forms and dominant forming processes. It has been used to designate the preservation area for the protection of natural environment, to build the plan for disaster prevention and to provide the basic information for social infrastructures. There is strong need for introduction of national geomorphological mapping. The map of landform classification of the quaternary alluvial deposit area of the Jiseokcheon, a tributary of Yungsan River in this study. The Landform classification scheme is developed by typical landscape system constructed based on field survey and co-work with British Geological Survey. The information gathered through boring core also used to classify the landforms. Based on this classification system, characteristics of alluvial deposit of 1:25,000 Neungju, Yonggang, Dongga, Boseong were depicted on the map. All 7 landforms at quaternary alluvial deposit area are identified in this study: fluvial terrace, flood plain, old(abandoned) channel, natural levee, alluvial fan, colluvium and manmade landforms. More detailed field survey using GPS and GPR, physical and chemical analysis of sediment layer and age estimation of land forms should be included in future. In addition this mapping program should be extended to nationwide by government.
