Journal of Coastal Research, Special Issue No. 116, pp. 443-447. Charlotte (North Carolina), ISSN 0749-0208. In the present study, case study methodology was used to examine plans for establishing a safety management system for waterfront spaces related to marine leisure activities in Korea. The findings in the study were as follows: First, public-private cooperation system should be established through the launching of a national marine leisure management committee. Second, the national lifeguard qualification system of Korea should be used to increase the professionalism for safety management and rescue/salvage operations. Third, a rescue system using state-of-the-art equipment, including drones, should be established from a long-term perspective. [ABSTRACT FROM AUTHOR]

ABSTRACT Yoon, I.J., 2018. Perspectives of Government Officials and Professional Experts on the Hydrographic Surveying of Bathing Beaches in the Republic of Korea. 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. 1376–1380. Coconut Creek (Florida), ISSN 0749-0208. This study aimed to investigate and present stakeholders' perspectives on hydrographic surveys of bathing beaches in the Republic of Korea. Questionnaires targeting local government officials and hydrographic survey experts were designed, distributed, and collected. Hydrographic survey experts were found to be more supportive than local government officials towards the necessity for legally enforced beach boundaries with exact coordinates, survey-based decisions, participation of registered surveying businesses, and equal intervals of measuring lines. In contrast, local government officials were more supportive of voluntarily set beach boundaries, provision of technical guidance, and different intervals of measuring lines. These results indicate the existence of complicated dynamics and ambiguities surrounding hydrographic surveying in Korea. Overall, the survey answers were influenced by administrative responsibilities and relevant expertise. Based on these results, 98.2% of bathing beaches should require no more than 41 measuring lines, reducing the time and budget required for surveying. Following the passage of the Act on the Use and Management of Bathing Beaches in 2014, stakeholders are facing a paradigm shift in beach management with regard to natural conditions and the long-term development of bathing beaches.

Lee, G.; Hong, S.; Lee, C.; Kim, J., and Lee, J., 2016. Rip current zoning map to manage safety at Haeundae Beach, Korea. In: Vila-Concejo, A.; Bruce, E.; Kennedy, D.M., and McCarroll, R.J. (eds.), Proceedings of the 14th International Coastal Symposium (Sydney, Australia). Journal of Coastal Research, Special Issue No. 75, pp. 1452-1456. Coconut Creek (Florida), ISSN 0749-0208. Rip currents are well-known in South Korea. Between July and August 2012, rescue workers covering Busan's beaches were on high alert for rip currents. Rescuers pay particular attention to Haeundae Beach near the Paradise Hotel because it is the frequent site of these currents. In July and August of 2012, 62 fast-moving rip currents were observed with maximum speeds of 2.5 m/s. During this period 187 people were rescued at Haeundae Beach after being dragged into deeper waters by these currents; fortunately, no casualties were reported. Authorities caution that ideal weather conditions for rip currents will persist, so this phenomenon could occur again at any time. In response to this public safety threat, the Korean Meteorological Administration plans to implement automatic monitoring systems for forecasting rip current generation at Haeundae Beach. In this study, we propose an approach for mapping the rip current risk to improve safety management at Haeundae Beach. First, we determine the spatial occurrence rate of rip currents using a field monitoring system based on closed-circuit television (CCTV) images and the Haeundae Current Model (HAECUM) rip current prediction system; the velocity and direction of the rip currents are also considered. This information is then combined with vulnerability factors such as the distribution of beachgoers and the capacity of lifeguards to produce a risk assessment map of rip currents at Haeundae Beach.

A periodic and long-term beach monitoring and diagnostic system is developed for the design and assessment of coastal development plans at coastal zones of Gangwon Province. Nearly 300km shoreline appears along the east coast of Gangwon Province. A few beaches are under the control of military forces to keep citizens away. The coastal zone named Donghaean is composed of three major watershed zones. The beaches in this area are heavily influenced by the presence of coastal prevention projects including groins, detached breakwaters and seawall. Dataset of shorelines and beach profiles is consequently stored by the developed monitoring system and used to interpret the consequences of past events, while the beach diagnostic system is developed to predict the impact of future ones. This system covers a large coastal stretch divided into 20 watershed sectors for littoral analysis. One-dimensional inverse method and new sediment transport model (diffraction effects included) are used as a main tool to analyze and predict shoreline changes, respectively. In addition, two types of morphological models are also employed to investigate the more detailed seabed changes in the vicinity of fishery ports or river inlets. [ABSTRACT FROM AUTHOR]
