본 논문은 레이더 유량계를 활용하여 영구저류지의 유입·유출량을 계측을 통해 영구저류지의 재해저감효과를 분석하였다. 2009년 이후 자연재해대책법 의거 개발사업에 대해 재해영향평가를 실시하고 개발 후 영구저류지를 설치토록 법제화하고 있다. 재해영향평가서 상 50년 빈도 강우량으로 영구저류지를 설계하고 있지만, 크기 및 형태에 대한 평가는 이루어지지 않고 있으며, 이상기후로 인해 강우강도가 높은 폭우가 지속적으로 증가하고 있어 이에 대한 평가가 필요한 상황이다. 영구저류지의 재해저감효과를 확인하기 위해 유입·유출구에 레이더 유량계를 설치하였고 24시간 강우사상 동안 발생한 유입·유출량을 확인하였다. 획득 데이터를 통해 사전재해영향검토서의 기대 저감효과 영구저류지의 실제 저감효과 비교 분석을 하였고,이를 바탕으로 저감효율을 계산하여 영구저류지의 재해저감효과에 대한 구체적 평가를 수행하였다.

An annual average of more than 100 casualties occur on construction sites designated by the occupational safety and health law despite the safety assessment regulations from Korea Occupational Safety & Health Agency. Even if those sites involve more harmful or hazardous work than other sites, the result creates doubt regarding the effectiveness of the safety assessment regulations. The safety of construction sites is difficult to maintain continuously and instantly because ofthe variability in the construction industry despite inspecting workers, equipment, and facilities by managers. Many discussions on how to utilize BIM have been made to improve the productivity of construction projects, and BIM-based modeling and simulation would bring many benefits to safety. This study examined the hindrance factors of field utilization of the safety assessment regulations through a research literature survey, disaster situation analysis and questionnaire, and suggests the necessity of the application of BIM that enhances the effectiveness of safety assessment regulations by identifying the relationship between the hindrance factors and the function of BIM.

Coastal disasters have become one of the most important issues in every coastal country. In Korea, coastal disasters such as storm surge, sea level rise and extreme weather have placed many coastal regions in danger of being exposed or damaged during subsequent storms and gradual shoreline retreat. A storm surge is an onshore gush of water associated with a tow pressure weather system, typically in typhoon season. However, it is very difficult to predict storm surge height and inundation due to the irregularity of the course and intensity of a typhoon. To provide a new scheme of typhoon damage prediction model, the scenario which changes the central pressure, the maximum wind radius, the track and the proceeding speed by corresponding previous typhoon database, was composed. The virtual typhoon scenario database was constructed with individual scenario simulation and evaluation, in which it extracted the result from the scenario database of information of the hereafter typhoon and information due to climate change. This virtual typhoon scenario database will apply damage prediction information about a typhoon. This study performed construction and analysis of the simulation system with the storm surge/coastal inundation model at Masan coastal areas, and applied method for predicting using the scenario of the storm surge.
