Abstract
The Nakdong River in South Korea is about 510 km long and is subject to natural erosion and sedimentation and various potential sources of human pollution, such as urban dumping and input from industrial complexes and many cities. The Noksan Dam, built in 1934, blocks the flow of the West Nakdong River, and the Nakdong Estuary Bank was completed in 1987 to regulate flow from the Nakdong River. This study developed a marine environmental information system (MEIS) to understand the land– sea interaction and provide data on the characteristics of the brackish water zone around the barrier islands. Beginning in May 2015, the MEIS was run in real time (1-second intervals) and periodic marine observations (1– 4 times a year). The real-time data are largely obtained from closed circuit television (CCTV) and automatic weather stations (AWS) using long-term evolution (LTE) communication at two stations in the Doyodeung barrier islands. Monitoring system (salinity, temperature, chlorophyll a, etc.) will be installed near the Eulsukdo Bridge, which are expected to be installed by the end of 2018. The data include periodic observations of sediment distributions (n = 90), the characteristics of suspended sediments in inlets and channel (n = 4), seasonal variation in sedimentation along tidal flats (n = 29, 3 lines) and landscape classifications of sub-environmental (n = 30, 14 a priori groups) in the barrier islands.
