Field Experiment to Check the Performance of New Wave Dissipating Block

ABSTRACT Oh, Y. and Kim, S., 2018. Field experiment to check the performance of new wave dissipating block. In: Shim, J.-S.; Chun, I., and Lim, H.S. (eds.), Proceedings from the International Coastal Symposium (ICS) 2018 (Busan, Republic of Korea). Journal of Coastal Research, Special Issue No. 85, pp. 1076–1080. Coconut Creek (Florida), ISSN 0749-0208. Verification of the damage coefficient of a newly developed wave dissipating block named Chi-block has been attempted via field tests. Usually, the concerned damage coefficient is determined via hydraulic experiments, and the block is used in the field without in-situ verification. The test breakwater was constructed in Marado, and 5-tonne blocks were installed in front of the breakwater having a 1:1.5 slope. In order to measure the movement of the block, a 3-dimensional acceleration sensor was installed in the block, and a pressure-type wave recorder was installed near the breakwater to measure the wave height causing displacement of the block.
