Abstract

Lim, C., 2023. Prediction of equilibrium shoreline by wave environmental change using MeePaSoL Software. In: Lee, J.L.; Lee, H.; Min, B.I.; Chang, J.-I.; Cho, G.T.; Yoon, J.-S., and Lee, J. (eds.), Multidisciplinary Approaches to Coastal and Marine Management. Journal of Coastal Research, Special Issue No. 116, pp. 648-652. Charlotte (North Carolina), ISSN 0749-0208. Recently, coastal hazards are increasing around the world due to accelerated beach erosion overlapped with climate change. To reduce the risk on the beach, analyzing waves is primarily required because beach composed of sediment continuously respond to the incidence of wave energy. The equilibrium shoreline is reshaped according to the predominant wave direction. The parabolic bay shape equation, which is mainly cited in coastal engineering, also gives different results for the equilibrium shoreline depending on the predominant wave direction. On the other hand, wave height affects the retreat of the equilibrium shoreline. An approximation formula for peak erosion width indicates that not only peak wave height but also mean wave height affect shoreline retreat. In this study, wave environmental changes from the past to the present are analyzed using hindcast data for more than 40 years provided by NOAA. In addition, the future wave environment is estimated from the analyzed change trend. Finally, the equilibrium shoreline is predicted considering the remodeling and retreat of the shoreline according to the analyzed wave environments using MeePaSoL software. This study is expected to be helpful in preliminarily examining beach erosions due to wave environmental changes.
