Application of a Geo-tube in Reducing Estuary Accretion and Beach Erosion at Jinha Beach in Ulju-gun, South Korea

Jang, S.Y.; Kim, H.J., and Cho, W.C., 2019. Application of a geo-tube in reducing estuary accretion and beach erosion at Jinha beach in Ulju-gun, South Korea. 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. 6-10. Coconut Creek (Florida), ISSN 0749-0208.Estuary accretion and beach erosion occur simultaneously at Jinha beach in Ulju-Gun, located in the eastern part of South Korea. Coastal monitoring has been performed to understand the causes of estuary accretion and beach erosion at Jinha beach. An 80-m-long geo-tube was installed between the Myungseon island and the salient at Jinha beach, where sediment transports are active, to reduce estuary accretion and beach erosion. In this study, we analyze the coastal monitoring data and provide analysis results to establish additional countermeasures to reduce estuary accretion and beach erosion at Jinha beach.
