Description
Summary:Kim, J.-S.; Hur, D.-S.; Park, T., and Jeong, Y.-M., 2023. The effect of groundwater level reduction by installing drainage layers for beach deformation. 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. 131-135. Charlotte (North Carolina), ISSN 0749-0208. Coastal areas are favorable for the establishment of industrial facilities from an economic perspective and provide valuable space for tourism and leisure activities. However, these areas have faced significant problems since the late 20th century due to indiscriminate development and accelerated erosion caused by global warming. To prevent erosion, various coastal structures such as submerged breakwaters, detached breakwaters and groins are used for coastal restoration projects. However, the coastal structures used in coastal restoration projects might cause secondary damage. This study performed a movable-bed hydraulic experiment using a gravity drainage method that installs drainage layers with different permeability in the beach to naturally drain groundwater into the sea, thus reducing coastal erosion while minimizing the risk of secondary damage.
