Topographic Dataset around Uljin Hujeong Coast Using Multi-beam Echo Sounder and Shipborne Mobile LiDAR

Abstract

We obtained a dataset through beach and submarine topography surveys around Hujeoung coast in Uljin. We conducted the beach and submarine topography surveys using small vessels from July 8 to July 11, 2016. The surveying instruments used for the surveys were Shipborne Mobile LiDAR System and Multi-beam Echo Sounder (Kongsberg EM3001). The beach topography was observed up to about 6 m from the shoreline. The width of the beach is about 30 m to 40 m. In the southeast of the survey area, there is an exposed rock with a depth of about 20 m. The area around the rock has sandy sediments. Datasets of the Hujeong coast area can be used for continuous monitoring to development of coastal erosion control system.
