Jeong, H.Y., 2019. A study on changes in coastal erosion environment by time series coastal detection using GIS. In: Lee, J.L.; Yoon, J.-S.; Cho, W.C.; Muin, M., and Lee, J. (eds.), The 3rd International Water Safety Symposium. Journal of Coastal Research, Special Issue No. 91, pp. 331-335. Coconut Creek (Florida), ISSN 0749-0208.

This paper identifies major coastal erosion factors for Hupo beach of the east coast of Korea where coastal erosion is serious, and looks into how beach erosion environment has changed through time series analysis (1970 - 2015). Aerial photographs of the beach by each time period were used to calculate the area of the beach, and analysis of correlation with identified factors on top of trend analysis were done to find and analyze major factors that have an impact on long-term changes in the beach. This paper is expected to contribute to identification of future coastal erosion factors, building-up and application of database, and policy-making to respond to changes in coastal erosion environment.
