강우는 자연과 인간에게 중요한 자원이다. 적절한 강우는 농작물의 성장과 토지의 온도를 일정하게 유지시켜줌으로써 우리 사회가 안정적으로 유지되도록 하는 매우 중요한 역할을 한다. 그러나 태풍 및 집중호우 등과 같이 특정 지역에 계획강수량보다 더 많이 발생한 집중강우는 시설물 및 인간에게 커다란 피해를 입히기도 한다. 이에 따라 미국, 일본 등 국외 선진국의 수재해 대응기관들은 시설운영자와 재난전문가, 응급대응인력들에게 가이드라인을 제공하기 위해 수재해 EAP(Emergency Action Plan)를 작성 운영하여 시설물을 보호하고 강화하는데 활용하고 있다. 대표적인 예로, 미국의 FEMA와 DHS는 시설물과 인명을 보호하기 위해 댐, 제방 등을 위한 다양한 EAP를 운영하고 있는데, 특히 FEMA는 EAP를 시설물이나 인명에 가해지는 피해나 기능적 충격과 같은 응급상황을 감소시키기 위해 작성하는 공식문서로 규정하고 있으며, 이 EAP를 통해 응급 시에 발생할 수 있는 모든 상황뿐만 아니라 평상시 발생할 수 있는 시설물관리상의 문제까지 대응이 가능하도록 규정하고 있다. 이에 본 연구에서는 미국, 일본 등 국외주요국과 국내에서 사용중인 EAP 관련 규정을 분석하여 국내 상황에 적합한 EAP 체계를 제안하였다. EAP는 예방, 준비, 대응, 복구의 재난단계별로 시설물과 인명을 보호하기 위해 재난전문가들과 시설운영자들이 취해야 할 업무, 응급장비 운용 등의 내용을 담고 있다. 본 연구를 통해 개발된 EAP 프레임워크는 테스트베드 적용을 통해 적정성을 평가받았으며, 국내 홍수재난 위험을 감소시키기 위한 절차와 방법 개선에 기여할 것으로 기대된다.

Probabilistic information regarding directional extreme wind speeds is important for the precise estimation of the design wind loads on structures. A joint probability distribution model of directional extreme typhoon wind speeds is established using Monte Carlo simulation and empirical copula function to fully consider the correlations of extreme typhoon wind speeds among the different directions. With this model, a procedure for estimating directional extreme wind speeds for given return periods, which ensures that the overall risk is distributed uniformly by direction, is established. Taking 5 typhoon-prone cities in China as examples, the directional extreme typhoon wind speeds for given return periods estimated by the present method are compared with those estimated by the method proposed by Cook and Miller (1999). Two types of directional factors are obtained based on Cook and Miller (1999) and the UK standard's drafting committee (Standard B, 1997), and the directional risks for the given overall risks are discussed. The influences of the extreme wind speed correlations in the different directions and the simulated typhoon wind speed sample sizes on the estimated extreme wind speeds for a given return period are also discussed.

An increase in oil and gas plants caused by development of process industry have brought into the increase in use of flammable and toxic materials in the complex process under high temperature and pressure. There is always possibility of fire and explosion of dangerous chemicals, which exist as raw materials, intermediates, and finished goods whether used or stored in the industrial plants. Since there is the need of efforts on disaster damage reduction or mitigation process, we have been conducting a research to relate explosion model on the background of real 3D terrain model. By predicting the extent of damage caused by recent disasters, we will be able to improve efficiency of recovery and, sure, to take preventive measure and emergency counterplan in response to unprepared disaster. For disaster damage prediction, it is general to conduct quantitative risk assessment, using engineering model for environmental description of the target area. There are different engineering models, according to type of disaster, to be used for industry disaster such as UVCE (Unconfined Vapour Cloud Explosion), BLEVE (Boiling Liquid Evaporation Vapour Explosion), Fireball and so on, among them, we estimate explosion damage through UVCE model which is used in the event of explosion of high frequency and severe damage. When flammable gas in a tank is released to the air, firing it brings about explosion, then we can assess the effect of explosion. As 3D terrain information data is utilized to predict and estimate the extent of damage for each human and material. 3D terrain data with synthetic environment (SEDRIS) gives us more accurate damage prediction for industrial disaster and this research will show appropriate prediction results.

This paper describes the design and trial development of a system that supports continuous hazard mapping by local residents in their daily life. We performed an interview survey to design our system in a model traditional town in Saga Prefecture, Japan. The results show that despite continued efforts, many practical problems remain and residents feel unsafe. Considering these results, we designed and developed a unique information and communication technology-based support system that contributes to community-based disaster prevention and reduction. The continuous resident participation and posting design are the core concept for our community-based approach. Our system continues to support making a hazard map by integrating the community-based hazard information. Local residents register information (disaster types, risk level, photographs, comments, positional information) about locations that could be dangerous in a disaster. In addition, our system enables information sharing through a Web server. We expect that this information sharing will allow local hazard information for each district to be used.

건설산업의 중대재해 발생률 및 사망률이 가장 높아짐에 따라 이를 감축하기 위해 국내에서도 다양한 노력을 기울이고 있다. 그 중 위험성 평가는 시공단계 위험요소를 평가하고 재해 감소대책을 위한 자료로 활용되고 있다. 그러나 기존의 위험성 평가는 수행자의 주관이 개입되며 국내 건설현장에 취약한 측면이 있다. 본 연구는 위험성 평가 분야에 BIM을 활용하여 정량적으로 위험요소를 도출함으로써 리스크를 조기 식별하고 사전제거하는 것을 목표로 위험성 평가를 위한 DB 분류체계를 구축하였으며 BIM을 활용한 위험성 평가의 방법론을 제시한다. 이를 통해 리스크의 사전 제거로 시공 작업자의 안전성을 증대시키고 안전관리 분야의 추가비용을 절감한다. 또한, 신규 공법에도 적용 가능하므로 프로젝트 참여자들의 이해도를 높이며 의사소통의 도구가 된다. 본 연구는 BIM을 기반으로 정량적인 위험도를 도출하는 프레임워크를 제안하는 연구로써, 향후 BIM을 활용한 위험성 평가 분야에 기반 기술로 활용될 것이다.

Floods are the most common natural disasters and are annually causing severe destructions worldwide. Human activities, along with expected increased extreme precipitation patterns as a result of climate change enhance the future potential of floods. There are proven evidence that infrastructure based responses to flood disaster is no longer achieving optimum mitigation and have created a false sense of security. Nature-based solutions(NBS) is a widely accepted sustainable and efficient approach for disaster risk reduction and involves the protection, restoration, or management of natural and semi-natural ecosystems to tackle the climate and natural crisis. Adoption of NBS in decision-making, especially in developing nations is limited due to a lack of sufficient scenario-based studies, research, and technical knowledge. This study explores the knowledge gap and challenges on NBS adoption with case study of developing nation, specially for flood management, by the study of multiple scenario analysis in the context of climate, land-use change, and policies. Identification and quantification of the strength of natural ecosystems for flood resilience and water management can help to prioritize NBS in policymaking leading to sustainable measures for integrated flood management.

Korea is surrounded by the West Sea, the South Sea, and the East Sea. There are various points at which large and small rivers flow into the sea, and areas where these rivers meet the coast are vulnerable to disasters. Thus, it is necessary to study disaster prevention techniques based on coastal characteristics and the pattern of disasters. In this study, we analyzed the risk factors of disaster districts analyzed in comprehensive plans for the reduction of damage to coastal cities from storms and floods. As a result of standardization, four factors (tide level, intensive rainfall & typhoon, wave, and tsunami) were identified. Intensive rainfall & typhoon occurred along the West Sea, the South Sea, and the East Sea coast. Factors that should be considered to influence disasters are tide level for the West Sea, tsunami and tide level for the South Sea, and wave in the East Sea. In addition, disaster prevention techniques to address these factors are presented, focusing on domestic and overseas cases.
