Owing to an increase in leisure and industrial activities, the coastal activity area is expanding and the incidence of coastal accidents is increasing. To solve this problem, it is necessary to derive an optimal and efficient response plan that requires little manpower through a clear understanding of the characteristics and causes of accidents. To this end, this study classified accidents according to three criteria of location, type, and causes of accidents based on the coastal accident cases provided by the Korea Coast Guard and analyzed the correlation between each classification criteria by applying statistical techniques. On the west coast of Korea, where the tidal difference is large and it is highly correlated with isolation accidents caused by the tide, near sea rock and mudflats; on the east coast, where the frequency of high waves is high and it is highly correlated with falls or drift drowning accidents caused by waves near breakwaters and beaches. This correlation indicates that an effective proactive response is possible by identifying the type and cause of accidents by accident location. Coastal accidents can be reduced by eliminating coastal safety blind spots due to a lack of manpower through efficient management and supervision of coastal activity areas using the results of the correlation analysis between accident locations, types, and causes analyzed in this study.

Coastal management begins with risk control, which is a collection of methods for evaluating the potential for harm and taking action to reduce or eliminate risk. Four methods of risk control are commonly employed: transferring, taking, avoiding, and reducing risk. These methods can be adjusted based on continuous monitoring. Risk assessment is the most commonly used method employed for the selection of risk-control measures. In this study, a risk-assessment-based information-provision method was proposed as a control measure for the risks that pose a threat to the safety of coastal users. The proposed risk-assessment method complements the current qualitative and subjective risk- assessment methods used by the Korea Coast Guard. A risk-assessment index and evaluation method were established to assess the risk grade of coastal activity areas managed by the Korean Coast Guard. This method was applied to 40 representative hazardous areas designated and managed by each regional office. By applying the established risk-assessment system, 11 sites were classified as grade 2, 25 as grade 3, 3 as grade 4, and 1 as grade 5. The risk grade of hazardous areas under the jurisdiction of the Korea Coast Guard Region-Central, which has a high rate of accidents and fatalities, was rated higher than that of other regional offices. The risk grade of each regional office, except for the central office, was rated between grades 2 and 3. [ABSTRACT FROM AUTHOR]
