As high-rise buildings came in, the landscape of rural areas and natural landscapes often got damaged. Therefore, this study aims to prevent this, grasp the extent of the influence of the surrounding landscape, to grasp the range of height that can be permitted and present the direction of landscape management of agriculture and natural landscape. This study tried to grasp the range of height by using price sensitivity analysis method for two apartment and apartment complex which entered DangJin city and SeoSan city. First, in the case of a two apartment, the range of the height allowable section was from the 6th floor to the 11th floor in close range view, and it was a section from the 7th floor to the 12th floor in medium range view. In the case of the apartment complex, the range of the height allowable range was from the 10th floor to the 17th floor in close range view, the 9th floor to the 16th floor in medium range view. The stress index was found to be positive in a two apartment in close range view, and in the apartment complex case. therefore it was better to set it to a lower in the Range of Acceptable Height(RAH). Second, it showed no difference in the sensitivity of landscape to gender. Thirdly, the results of the landscape sensitivity analysis of major and non-major showed the difference in the medium range view picture of the apartment complex. Majors are lower than the point of minimum height(PMinH) than non-Majors. In the case of major, the stress index was 1.4. it turned out that it was better to make a decision closer to point of minimum height (PMinH). In the case of non-major, the stress index was –1.3. it was also able to accept decision close to the point of maximum height (PMaxH). Since the results of the above research gave changes only in the variable of the height of the landscape, we can not grasp the point of interaction with other variables, and future research is considered necessary.

최근 중·소규모의 도시전역과 자연유역에서 임계지속기간의 개념을 도입하여 설계홍수량을 산정하는 사례가 늘어나고 있는 추세에 있다. 그러나, 임계지속기간에 관한 연구는 미흡한 상태이며 특히 자연유역에 대해서는 거의 없는 상태이다. 따라서, 본 연구에서는 자연유역을 대상으로 Clark모형을 이용하여 강우분포 형태, 첨두강우 발생위치, 빈도에 따른 임계지속기간 및 첨두유량을 산정하고, 적용모형의 매개변수들에 대한 민감도분석을 실시함으로써 각종 인자들이 설계홍수
