ABSTRACT

Mountain streams in Gangwon-do are characterized in that quicksand rapidly moves downstream in torrential rain because they are steep and have short channels. In particular, there are various topographic changes according to the river flow characteristics and flow at the mouth of the river which meets the east coast of Korea. In addition, estuary closure caused by an increase in sand deposits forms hazard areas in the fluvial environment. Therefore, this study analyzed the effects of changes in topography at the mouth of the Gagokchen in Samcheok-si, Gangwon-do with the use of terrestrial LiDAR used for geomorphology, changes in coastline and fluvial morphology and research of disaster site recently. As a result, height analysis of the topography showed the variation trends of each erosion and deposition site according to the estuary closure.
