초록

본 연구는 조경기술기반 LID 시스템 적용에 따른 선릉 정릉 권역의 우수유출변화를 수문학적 관점에서 분석하였으며, 연구결과를 다음과 같이 정리할 수 있다. 첫째, 광화문 침수가 발생한 2011년 7월 27일 기준 최대순간강우량은 27일 10시에 기록된 183mm/hr로 시간당 최대강우량 57.5mm/hr에 비해 3배 이상의 강우강도가 10분간 집중된 것으로 확인되었다. 둘째, 토심기준 시나리오에서 담심 1,500mm의 경우 첨두유출량 제어가 가능하여 해당 조경기술기반 LID 시스템 적용 시 선릉 정릉 권역의 수해취약성을 개선할 수 있을 것으로 판단된다. 셋째, 담심 기준 시나리오에서 모든 토심 모형에서 첨두유출량 제어가 이루어지지 않았으나, 최초 우수유출을 토심 기준 시나리오에 비해 4시간 10분의 추가적인 지연효과를 기록하였다. 초기 우수유출저감에는 토심, 첨두유출량에는 담심이 상대적으로 중요한 지표로 해석되었다. 이를 통해 문화재 보호권역 내 경관친화적인 생태적 요소를 시스템화하여 적용할 경우 예상되는 수해방재효과를 이론적으로 확인할 수 있었다.

This study analyzed hydrological changes of stormwater runoff of Seolleung Jeongneung zone according to the application of LID system based on landscape Architectural technology. The results are as follows. First, when flooding occurred in Gwanghwamun in July 27, 2011, the maximum instantaneous rainfall amount was 183 mm/hr recorded at 10:00 on 27th for 10 minutes, and it was confirmed that rainfall intensity more than three times as high as the maximum rainfall of 57.5 mm/hr. Second, it is possible to control peak flow rate in the case of 1,500mm of soil thickness, so that it is possible to improve the vulnerability of flood damage in Seolleung and Jeongneung zone when applying the LID system. Third, in the berm height scenario, peak flow rate control was not controled in all depth level models, but the first stormwater runoff was delayed by 4 hours and 10 minutes compared to the soil thickness scenario. It was interpreted as a relatively important indicator the soil thickness for the initial stromwater runoff reduction and the berm height for the peak runoff. Through this, the systematic adaptation of landscape-friendly ecological factors within the cultural property protection zone could theoretically confirm the effects of flood disaster prevention.
