하천은 크게 하도와 홍수터 그리고 제방으로 나눌 수 있으며, 최근 대하천 및 중 소규모 하천의 홍수터 공간을 활용하여 인공습지, 체육시설 및 공원 등과 같은 다양한 친수시설들을 조성하여 활용하고 있다. 이러한 홍수터는 여름철 태풍이나 집중호우로 인해 침수되다가, 강우 사상이 종료된 이후에는 유사가 퇴적되어 복구비용이 반복적으로 발생하고 있다. 홍수시 홍수터에서의 수리적 안정성을 평가하기 위해서는 홍수터를 포함한 복단면에서의 흐름해석이 선행되어야 하며, 계산된 수리적 인자들을 이용하여 홍수터에서의 수리적 안정성을 평가할 수 있다. 국외에서는 국내와 다르게 하천 홍수터 공간을 거의 활용하지 않기 때문에 홍수터에서의 수리적 안정성 평가에 대한 연구사례는 드문 실정이며, 도시침수로 인한 제내지 홍수위험도 평가에 대한 연구가 주를 이루고 있다. 하지만 기존에 사용되고 있는 제내지 홍수위험도 지수를 국내 홍수터에 도입하여 수리적 안정성을 평가하기에는 침식 및 퇴적을 올바르게 고려할 수 없는 한계점이 있기 때문에 본 연구에서는 홍수시 홍수터 내에서 침식과 퇴적을 고려할 수 있는 홍수터 수리적 안정성 지수를 산정하고 과거 연구된 실내 수리실험 자료와 비교하여 적용성을 분석하고자 한다. 또한 자연하천에서의 실제 태풍 사상에 의한 침식 및 퇴적의 상대적 공간분포를 산정하여 홍수터에서의 수리적 안정성을 평가하고자 하였다.

Seoul City planned "Dreamland" to be in harmony with the huge woods and park. It is located in the life zone in the northern region of Seoul as part of an extensive park development plan that the municipal government has promoted. The space configuration technique of the aesthetics of "Empty" rather than "Full" gives the potentiality to cope with the uncertain changes in the city. Furthermore, the traditional element of the mountain landscape of Seoul was introduced and appropriated as the axis of the landscape for landscape configuration. In that configuration, the images of tree, sky, wind, water and soil are elegantly unfolded like a landscape painting. The purpose was to create a dominant landmark in the city landscape with the figures of Korean mountains and hills which were differentiated from architectural landmarks in the western cities by making nature, which was excluded from the urbanization plans up to now, an important subject for consideration. As a result, this study madethe space in a park including existing yards and streets in a city have the traditional hierarchy by applying the facility arrangement technique and elements extracted from Korean space types and traditional landscape concepts. Moreover, the North Seoul Dream Forest was designed by pursuing diversity and potentiality in the experience of space using a large open field in a city.

Vegetation established through the natural process, such as Quercus mongolica, Pinus densiflora, Q. variabilis, Q. acutissima, Carpinus laxiflora, Q. aliena and Q. serrata communities and artificially introduced vegetation, which are composed of Larix leptolepis and P. rigida plantations, are established in the mountainous land of the Mt. Songnisan National Park. On the other hand, the developed lands, which are consisted of agricultural folds, residential areas, commercial areas related to tourism, etc. appear in the lowland around streams. Based on the spatial distribution of vegetation, the southern district, which is attributed to Naesongni-myun by administrative system, showed higher natural degree and vegetation diversity. However, most of the other districts, which are attributed to Cheongcheon- and Chilseong-myuns, are covered with the Korean red pine forest, a product of artificial influence, and plantation also occupied higher percentage. Thereby both vegetation diversity and natural degree are lowering. A result of ordination by DCA showed that sands tended to be arranged by depending on the topographic condition. Species diversity of plant communities was higher in broad-leaved stands rather than in coniferous ones and in stands of the early stage than in ones of the late stage. The result of analysis on vegetation dynamics implied that vegetation of this region would be dominated by Carpinus laxiflora, Quercus mongolica and Pinus densiflora communities in the future. However, considered occurrence the of disturbance and response of vegetation on that, this estimation may different somewhat from an actual situation. Conservation strategies of the Mt. Songnisan National Park were discussed in viewpoints of landscape ecology, and conservation of major plant communities and biodiversity.

Construction of the water-friendly facilities in the apartment complex and industrial complex became popular these days. In planning water-friendly facilities, kinds, layouts, water sources, water quality and water circulation system should be studies. In this study, several alternatives for a regional industrial complex project were studies and a most reasonal alternative was selected. A main canal across the central part of the complex is the principle facility with ponds and parks. The water source alternatives were a river nearby, a reservoir, ground water and urban water supply system. For each system, water quantity and quality, circulation system, permit and maintenance were compared. The facilities should be constructed with natural material such as rock and gravel. Average depth and velocity in the canal should be 10 cm and 0.15 m/s, respectively in order to people can feel the water flow in the canal. Based on the comparison, it is found that using the ground water, and water circulation system with storage tanks at the upper and lower ends of the canal system is the best alternative.

This is the urban design master plan for the Public Administration Town. The project proposes a newly configured city, where environmental and democratic principles are expressed in the shape of the urban fabric. To achieve the goal, the concepts of 'Flat City, Link City, and Zero City' were introduced. These concept show "Space fabric arrange, connection and material circulation and flow from ecological landscape". 'Flat City' shaped the government buildings into an iconic plane, and democratic society. The iconic plane's surface extends across the whole city, creating an expansive public park, which is easily accessible, and open to nature. 'Link City' connects governmental agencies to enhance their function and interactions. Government facilities, parks and green spaces, cultural facilities, commercial zones, and residential districts areas create an interconnecting network. 'Zero City' has integrated infrastructure systems to reuse waste, reduce pollution, and provide essential city functions. It creates a new wildlife habitat, making 'Zero City' a good neighborhood. This proposal was made to integrate historical, regional, nature experiences with various approaches in architecture, city, and landscape architecture.

This study, as a case where the environmental conflict and dispute arose between the use and the conservation as in the other protected areas in Korea, took the first step to build ecological citizenship to solve various and complicated issues in a fundamental level by providing a basic information on differentiated environmental perceptions of the locality and the visitors of Seoraksan National Park. The questionnaire survey was employed on September 6th and 7th with 150 residents of the park area and 200 visitors of Osaek-Daechungbong trail. Total number of 13 survey questions was introduced using Dunlap and Liere's NEP index. The result shows that the perception of 'balance of nature' was more dominant to the perception of 'humans over nature' and the perception to the 'limits to growth' was also somewhat positive in both groups. The differences in environmental perceptions between the groups exist; the visitor group tended to have more positive level of acceptance of NEP views. Such differences in perceptions suggest that a different normative approach should be taken to the residents of the national park with less pro-environment in their perceptions when policy making. It thus seemed possible that ecological citizenship could be realized since the younger and the higher education level are, the more pro-environment. The findings of the research may cause some concerns however, because the study has been confined as a case study with basic understanding of environmental perceptions and its differences between the interest groups. More extensive research is required to confirm if this is generalized.

The objective of the study is to analyze the impact of zone adjustment by comparing the changes from 2011 to 2018 of social and environmental factors such as the special-purpose area, actual construction activities including building development, land use environment, and officially assessed individual land price in the areas released from the National Park Zone during the second National Park Zone adjustment during 2010 to 2011 with the social and environmental factors in the areas that remained in the National Park Zone during the same period. We intended to investigate the problems of the second National Park Zone adjustment and explore alternative implications for the third National Park Zone adjustment. As for the special-purpose area, 80.4% of the released areas were converted to planned, production, and conservation area while 15.6% changed to the agricultural area, and 4.0% remained as the natural environmental conservation area. Regarding the change in building development scale, the average size of construction in the released area since 2011 was $106m^2$ while that in the retained areas was $91m^2$. For the land use environment, the rate of change from the natural area to developed area was 1.9% in the released area and 0.7% in the retained area. The officially assessed individual land price increased by 11,911 won in the released area and 4,413 won in the retained area. Although both areas showed an increase in the land price, the difference of officially assessed individual land prices was about 2.5 times. The problem concerning the private property rights of local residents in the national parks is still a challenge, but the second National Park Zone adjustment has resolved the problem significantly. Accordingly, it is necessary to offer the benefits for the residents in the national park area by analyzing the park zoning and park facility planning to present the rational alternative. It is also necessary to establish a support system that encourages the collaborative cooperation between the park authority and residents and assures that the residents to have pride in the national park.

하천은 크게 하도와 홍수터 그리고 제방으로 나눌 수 있으며, 국내에서는 다른 국가들과 다르게 대하천사업 이후 하천의 홍수터에 생태공원이나 체육시설 등과 같은 다양한 친수시설들을 조성하여 활용하고 있다. 하지만 최근 이상기후로 인해 홍수의 발생빈도 및 강도가 증가하고 있으며 여름철 집중호우에 의한 하천의 홍수위 상승은 이러한 친수시설의 침식과 퇴적 등과 같은 침수피해를 가중시키는 원인이 되기도 한다(Ku et al., 2013). 따라서 이와 같은 홍수피해를 예측하기 위해서는 홍수터를 포함한 복단면에서의 수치해석이 선행되어야 하며, 일반적으로 2차원 수치해석이 바람직한 것으로 제안되고 있다(Sato et al., 1989). 또한 하천에서의 2차원 수치해석 결과를 이용하여 침식과 퇴적에 관한 친수시설 안정성 평가 지수를 산정할 수 있으며, 산정된 지수를 통해 홍수터에서의 홍수피해를 예측할 수 있다. 다른 국가에서는 국내와 다르게 홍수터에 대한 활용이 거의 없기 때문에 홍수에 따른 홍수터에서의 위험도를 평가한 연구는 거의 없는 실정이며, 한국에서도 홍수터에서의 홍수위험도 평가에 대한 연구는 Song et al.(2016)이 다른 국가에서 활용하고 있는 제내지에서의 홍수위험도 평가 지수를 홍수터에 도입하여 실제 태풍에 의한 홍수위험도를 간접적으로 평가한 연구 정도가 대부분이라고 볼 수 있다. 따라서 본 연구에서는 Einstein-Krone 공식(1962)을 이용하여 침식과 퇴적을 동시에 고려할 수 있는 Transient Erosion and Deposition Index(TEDI)와 Steady Erosion and Deposition Index(SEDI)를 개발하였다. 또한 개발된 지수를 실제 자연하천에 적용하여 태풍 사상에서의 산정된 지수를 통해 홍수터 안정성을 평가하였다.
