  • In order to reduce flood damage, it is necessary to build up comprehensive flood control, including structural and non-structural countermeasures. In this paper, the decision making factors of individual refuge activities which are major non-structural activities to save peoples, lives against flood have been estimated based on questionnaire survey. Furthermore, in order to effective flood countermeasures, the refuge place and its distance are analyzed by questionnaire survey in the flooded area caused by typhoon RUSA and MEAMI. The refuge running time was assessed by its simulation. As a result of the simulation, it was found that the refuge running time is effected by refuge distance and the family numbers for refuge.

  • This study aimed at investigating elderly people's experiences and perception of flood disasters in Gangwon province, which is mainly devastated by flood disasters, and seeking to the coping strategy against vulnerability of disaster between elderly men and women. A total of 183 elderly people aged 60 and over who were directly or indirectly damaged by flood disasters of 2006 in Pyung-chang and In-je in Gangwon province were selected for this study. According to the study results, there were no statistical differences in disaster experiences between elderly men and women, however, a statistically significant difference was found in the perception of disaster among them. Although elderly women are more likely to perceive the possibility of secondary flood disasters than elderly men, elderly women are less knowledgeable than elderly men in disaster attacks and they have appeared to have low coping skills. This study showed that elderly women were more likely to live alone than elderly men and they have low income comparing to the elderly men. In conclusion, elderly women should be considered as a most vulnerable group to the disaster and gender-based approach is necessary to take measures in disaster prevention.

  • Fast track completion of urgent typhoon damage recovery construction project is becoming crucial for the prevention of the secondary damage from the next year typhoon, prompt psychological stabilization of flood sufferers, the early recovery of damaged infrastructure condition and so forth. As the recovery learning process has been continued for last consecutive typhoons and experts suggested, the keys in attaining the goals of the project (preventative, sustainable, cleaner and fast tracking development) are found to be the early contracting and improved competencies in project management especially during the design phase. It can be presumed that the former is attainable through administrative supports in the form of government guidelines, but the latter necessitates more research efforts. In this regards, this study aims to find a way how to lift up the current level of project management capability facing ever changing project mangement environment of urgent typhoon recovery project. By comparing the current level of application of government guidelines in flooded districts and analyzing the time required for each phase from design contracting to construction starting, several reformative ideas are illustrated in association with the necessity of adopting CM method in the deign phase. It is highly expected that CM application in the design phase can be an effective alternative in overcoming current limits in improving the quality of the project and prevent the delay due to the lack of expertise and professional workers in the owner side.

  • For the reduction of flood damage, it is necessary to analyse shelter activities of local residents and to publish information of floodings, In this paper the control factors of individual refuge activities which are major activities to save peoples lives against floodings have been estimated. Decision making factors for mental refuge activity by the questionnaire survey were classified into two categories: internal and external ones. Furthermore, the behaviour patterns of residents for flood risk related to geographical and social factors were derived by the quantification method n. Since spatial layered information using GIS were corrected and estimated to serve citizen's consensus due to flood disaster, it would aid reduction and minimization of flood risk.d risk.

  • The main purpose of this work is to analyse damages caused by debris flows during the heavy rainfalls at Inje of Kangwon Province, Korea. A series of site investigations have been carried out to survey the characteristics of debris flows occurred during the summer season of 2006. It has been found that major losses in human life and property are caused by discharge of soil and rock fragments from landslides. During the rainfall high precipitation rate of 113.5 mm/hour and 355 mm/day was recorded, which could happen at 80-500 year period. Comparing the rainfall record with the time of landslides being occurred, occurrence of the landslides is directly related to heavy rainfalls. At present, several debris barriers have been built at the valleys and natural slopes have been protected by the seed spray method. It is intended to propose an alternative of restoration of landslide damages and maintenance based on findings from the current study.

  • The flood damage due to heavy rainfall caused by not only geographical factor, but also social factors. In this paper we derived the flooding potential factors, and analyzed resident's understanding of flooding through the Tokai disaster of Japan, occurred in september 2000. Furthermore, the urban rate obtained by the data comparison between 1975 and 1985 using GIS is evaluated to estimate the effect of rainfall-runoff mechanism due to the urbanization. These efforts could be served as the information of flood damage for the communication with the residents and it would be helped the minimization of flood damage.

  • The main purpose of this study is to address flooding resilient land use management strategy based on the distributional characteristics of storm damage areas in Gyeonggi-do. The employed methods are 1) Exploratory Spatial Data Analysis (ESDA) to understand the spatial patterns of storm damage areas occurred from 2005 to 2009, 2) Local Indicator of Spatial Association (LISA) to examine spatial autocorrelation existed in storm damage areas for the year of 2009. The results show that 1) crop land damage is very sensitive to heavy precipitation, 2) damaged buildings are found in all over the Gyeonggi areas, but relatively more damages are in the regions closed to the City of Seoul, 3) damaged roads-bridges, streams, and reaches are found in mostly rural areas, 4) building and crop land damage occurs mostly in lowlands with different spatial patterns. These findings imply that 1) it will be useful to consider the average distances and slopes of damaged building and crop lands from streams for the decision making of land use management strategy, 2) further management efforts are required in the north, east, and south regions of Gyeonggi areas to prevent roads-bridge, stream, and reach damages, 3) the present land use pattern needs to be carefully investigated by considering the damage clustered areas for the year of 2009 based on watershed and municipality boundaries.

  • 본 연구의 목적은 자연재해나 인위재해로 인한 시설물 피해가 초래하는 경제적 영향을 분석할 수 있는 재해영향평가모형을 개발하고, 2002년도에 발생한 태풍 루사를 연구사례로 하여 본 연구에서 개발한 평가모형의 적용가능성을 살펴보는 것이다. 본 연구에서는 태풍 루사로 인한 시설물 피해가 초래하는 경제적 영향을 평가하기 위해서 경제분석모형인 다지역 투입산출모형(MRIO model)을 적용하여 서울시, 인천시, 경기도와 수도원외지역의 수해피해 영향을 분석하였다. 본 연구방법을 적용하여 지역별 산업별 경제피해영향을 분석한 결과 직간접 수해피해는 총 15조 4천 5백 2십 4억원이고, 고용손실영향은 총 265,476인으로 나타났으며 수도권외지역의 비중이 각각 88,8%와 88.1%를 차지하여 지방경제의 피해가 상당한 것으로 나타났다. 또한 복구비를 투자하였을 경우 총 21조 5천 9백 5십 7억원의 경제파급효과와 412,110인의 고용창출효과가 발생하고, 특히 수도권외지역에서 투자파급효과의 89.3%와 고용창출효과의 89.5%를 차지하여 지방경제 활성화에 크게 기여하는 것으로 분석되었다.
