  • Increase of impervious areas due to expansion of housing area, commercial and business building of urban is resulting in property change of stormwater runoff. Also, rapid urbanization and heavy rain due to climate change lead to urban flood and debris flow damage. In 2010 and 2011, Seoul had experienced shocking flooding damages by heavy rain. All these have led to increased interest in applying LID and decentralized rainwater management as a means of urban hydrologic cycle restoration and Natural Disaster Prevention such as flooding and so on. Urban development is a cause of expansion of impervious area. It reduces infiltration of rain water and may increase runoff volume from storms. Low Impact Development (LID) methods is to mimic the predevelopment site hydrology by using site design techniques that store, infiltrate, evaporate, detain runoff, and reduction flooding. Use of these techniques helps to reduce off-site runoff and ensure adequate groundwater recharge. The contents of this paper include a hydrologic analysis on a site and an evaluation of flooding reduction effect of LID practice facilities planned on the site. The region of this Case study is LID Rainwater Management Demonstration District in A-new town and P-new town, Korea. LID Practice facilities were designed on the area of rainwater management demonstration district in new town. We performed analysis of reduction effect about flood discharge. SWMM5 has been developed as a model to analyze the hydrologic impacts of LID facilities. For this study, we used weather data for around 38 years from January 1973 to August 2014 collected from the new town City Observatory near the district. Using the weather data, we performed continuous simulation of urban runoff in order to analyze impacts on the Stream from the development of the district and the installation of LID facilities. This is a new approach to stormwater management system which is different from existing end-of-pipe type management system. We suggest that LID should be discussed as a efficient method of urban disasters and climate change control in future land use, sewer and stormwater management planning.

  • Recently, due to localized heavy rain and flash floods in urban areas is becoming more frequent flood damage. To prevent flood inundation damage, to formulate the diverse directions in connection with the drainage system of buildings, roads, sewerage, pump stations, detention (retention) pond, and streams is very important. In addition, it is important for the uniform design criteria, the consistent of hydrologic and hydraulic analysis method, and a flood disaster mitigation systems connected with structural and nonstructural measures. To accomplish this, the method such as installation of storage facilities, infiltration facilities, and underground water tank, the optimal size of the design gutter and grate of the road, ensure the capacity of pumping stations, and the installation of a flood control channel into the deep underground requires comprehensive measures dimension in urban areas.

  • Korea has been suffering from various natural disasters. Slope-stability related disasters such as landslides usually occur during typhoon and torrential rain season. Types of slope-stability related disasters can be classified as failures in cut slopes along constructed roads, landslides in natural terrain, and retaining structure failures in urban area. This paper summarizes human casualties for the last 29 years in Korea, reviews field studies for the disaster sites that caused human casualties due to torrential rains in the Summer of 2005, analyzes causes of slope-stability related disasters and includes recommendations for an effective management system.

  • 본 연구에서는 재해 및 방재 관련 지명의 유형과 분포, 사례지역 조사를 토대로 지명을 통한 재해 및 방재 가능성을 탐색하였다. "한국지명총람"을 대상으로 106개의 검색 지명어에서 37,901개의 지명을 추출하였으며, 연구결과는 다음과 같다. 지명의 유형별 빈도는 지형재해 및 방재 관련 지명이 월등히 많았고, 특히 호우, 범람, 침수 재해와 관련된 지명이 탁월하였다. 지역적 분포는 영 호남 지역의 점유율이 높은 가운데 수(水), 사(沙), 야(野), 우(雨), 상(狀) 등이 전국적인 분포를 보인 반면 둠벙, 구렁, 여울, 탄(灘), 방죽, 제(提), 지(池) 등은 지역차가 커서 입지 및 지형적 특성이 지명에 투영되어 있음을 확인할 수 있었다. 사례지역 조사에서 우리나라는 기상현상과 지형조건이 결합된 범람 및 침수 재해의 가능성이 높아 수계와 곡지형에 대한 관리의 필요성이 제기되었다.

  • 최근 우리사회는 집중호우, 산사태 등의 재해발생으로 사회적으로 적지 않은 피해를 입고 있다. 이에 따라 재난 관련기관에서는 효과적인 대응체계를 마련하기 위해 많은 노력을 기울이고 있다. 특히, 스마트폰이 사회 여러 분야에서 폭넓은 활용이 이루어짐에 따라 재난방재 분야에서도 이를 활용하는 시스템 구축에 대한 연구 및 개발이 활발하게 진행되고 있다. 하지만 대부분 간단한 형태의 재난정보만 제공하기 때문에 사용자의 상황 및 요구조건을 고려하는 재난정보 서비스는 제공되지 않고 있다. 따라서 본 논문에서는 재난정보수집 및 제공이 상호 연계적으로 가능한 체계 구성과 사용자의 요구에 따라 정보를 검색할 수 있는 애플리케이션 기능을 구현하여 더욱 효율적인 재난정보서비스를 구축한다.

  • 최근 급증하는 이상기후의 영향으로 인하여 국지성 호우의 발생 빈도가 증가하고 있다. 이로 인하여 안전한 수자원 관리의 어려움이 증가하고 있으며, 인적 및 물적 피해가 늘어나고 있다. 국지성 호우로 인한 피해를 저감하기 위하여 다양한 대책방안을 수립하고 있으나 소규모 산지유역은 기본계획 수립 등의 부재로 인하여 어려움을 겪고 있다. 본 연구에서는 우리나라 국립공원 중 지리산 국립공원 중 유평유역을 대상으로 강우-유출모형을 활용한 침수 위험도 평가를 수행하였다. 지리산 유평유역은 재현빈도 50년 이상의 강우 발생 시, 홍수가 발생하는 것으로 모의 되었으며, 수공 구조물, 안전 시설물 및 탐방로에 대하여 위험성이 높게 나타나는 것을 확인하였다.

  • The typhoon, heavy rain, blizzard, storm and heavy snowfall had the main caused of natural disasters occurred in Korea from 1993 to 2002. Among them, typhoon has responsible for biggest disaster, recording about 47.4% of total economic damage. Typhoons concentrated mostly in the months from June to October. The average occurrence number in those months ranged from 3.9 to 5.5 based on 30 years of record(1971-2000). However, the numbers increased from 4.0 to 6.2 during the most recent 10 years(1991-2000). Jeju province, among others in Korea, was most frequently affected by typhoon which occurred 23 times during the period of 1991-2000. Typhoons which occurred from July to early August have passed mostly through the west of Jeju, whereas, those of late August to September have passed through the center and eastern sea area of Jeju. The typhoons 'Ramasun' and 'Rusa' caused severe damage in Jeju area in September 2003 and the surge heights were +39cm and +77cm, respectively. The main cause of the damage was surge height which was highly associated with the tidal phase at the time of typhoon passage. The damage caused by typhoon on the aquaculture, fishing boat and harbor cosatline wall around Jeju Island which was amounted to be 417 billion won(\) during the recent 3 years(2002-2004)

  • Background: Despite its growing significance, studies on the burden of disease associated with natural disasters from the perspective of public health were few. This study aimed at estimating the national burden of disease associated with typhoons and torrential rains in Korea. Methods: During the period of 2002-2012, 11 typhoons and five torrential rains were selected. Mortality and morbidities were defined as accentual death, injury and injury-related infection, and mental health. Their incidences were estimated from National Health Insurance Service. Case-crossover design was used to define the disaster-related excess mortality and morbidity. Disability-adjusted life years (DALYs) were directly assessed from excess mortality and morbidity. Results: The burden of disease from typhoons increased with the intensity, with 107.7, 30.6, and 36.6 DALYs per 100,000 per event for strong, moderate, and weak typhoons, respectively. Burden of disease from torrential rains were 56.9, 52.8, and 26.4 DALYs per 100,000 per event for strong, moderate, and weak episodes, respectively. Mental disorders contributed more years lived with disability (YLDs) than did injuries in most cases, but the injury-induced YLDs associated with strong typhoon and torrential rain were higher than those of lower-intensity. The elderly was the most vulnerable to most types of disaster and storm intensities, and males younger than 65 years were more vulnerable to a strong torrential rain event. Conclusion: The intensity of torrential rain or typhoon was the strongest determinant of the burden of disease from natural disasters in Korea. Population vulnerable may vary depending on the nature and strength of the disasters.

  • Currently, according to the climate change, the damages due to the hurricane is more increased than before. In this respect, several countries have been conducted the studies regarding the damage prediction model of buildings to minimize the damages from natural disaster. As hurricane is the complex disaster including a strong wind and heavy rain, to predict the damage of hurricane, various factors has to be considered. However, mostly research has been conducted to consider only hurricane properties. Therefore, the objective of this study is to develop the regression model for predicting damages of buildings considering geography, socio-economy, construction environment and hurricane information. In the future, this study can be utilized to developing damage prediction model for building from hurricane in South Korea.
