Geotechnical Information System (GTIS) for efficient management of three dimensional borehole data has been developed. Geotechnical maps in the vicinity of Bulkwangdong, Seoul station, Itaewon, Han river near Yuido, and Jungrangchon were constructed by Kriging method. In Bulkwangdong and Jungrangchon area where boundary between granite and gneiss is present, gneiss has been more weathered than granite, but in Seoul station and Itaewon area where the boundary is also present, granite has been more weathered than gneiss. It has been inferred that when Seoul granite intruded, the strength of gneiss in Bulkwangdong and Jungrangchon area was lowered by the attitude of foliation plane than in Seoul station and Itaewon area, so the gneiss has been easily fractured and weathered in Bulkwangdong and Jungrangchon area. Geotechnical map in the vicinity of Yuido showed that there is an NW-SE trend weakness zone that might be affected by major faults under Han river and it is expected that the fault zone may be present in construction area of Kyoungbu Highspeed Railway that lies below the Han river like the Subway Line No.5.

Riverfront plays an important role as accessible and inclusive public space for residents, and a riverfront development and management has become a social and environmental issue. The purpose of this study is to analyze Korean legislation and guidelines applied in a riverfront assessment process to identify any legislative problems. To this end, major laws, regulations, national river management plans, and various guidelines related to river management were reviewed. The followings are the suggestions proposed for future improvement. First, clear and consistent definitions on riverfront areas and its spatial range are required across the laws. Also, recreational activities and facilities in riverfront should be categorized and listed for possible development and maintenance. Second, it is necessary to develop an objective and unified riverfront assessment system. Also, guidelines for surveying and evaluating the conditions and potentials of riverfront should be developed. Third, efforts should be made to revise related laws and guidelines to enable comprehensive and systematic approach in design, planning, implementation, maintenance of riverfront. Improving the related legislations and streamlining an riverfront assessment process can help create environmentally-friendly riverfront spaces and mange them efficiently.

A protected area means a space designated and protected by law from development pressure and environmental pressure. It is mainly designated to protect specific ecosystems, natural landscapes, and cultural resources from irrational development (or damage), and involves policies of the public sector such as central and local governments. The United Nations Educational, Scientific and Cultural Organization (UNESCO) has conducted conservation and restoration projects for preserving natural ecosystems and genetic resources. In order to conserve the ecosystem in the protected area, national and public organizations purchase private land and use it ecologically; in addition, ecological restoration project is carried out for the purpose of creating waterside ecological belt or preserving ecosystem. Land acquisition refers to the land where highly influenced by the water quality and need to restore, and purchased by negotiating with the landlord. Although the nation and public institution carried out ecosystem restoration project for partial purchase land in order to conserve ecosystem, it is below the expected effect due to lack of comprehensive management system and have some problems in restoration project and unification of management institutions. Land acquisition in Donggang River Basin Ecological Conservation area is initiated in 2005 for creating income of local residents and ecological restoration. However, the lack of overall management and awareness resulted in poor vegetation growth and poor response by local residents due to terrain exposure. As such, there is insufficient research on the current situation and systematic integrated management although the number of land acquisition is increasing year after year. Futhermore, overall recognition and follow-up monitoring of eco-restoration are still inadequate. Therefore, the survey on the awareness of the purchase land ecosystem restoration project is necessary for the efficient restoration project and establishment of the management strategy for land acquisition in the future. Therefore, in this study, we provide fundamental materials on further research projects by carrying out research on the awareness of ecological restoration projects in the Donggang River basin ecological preservation area.

The management of water, both the quantity and the quality, has been one of the most important issues in the public investment and it is equally true in the field of sustainable development. Nevertheless, the jurisdiction of local governments has been delineated without much attention to the issue of the water management. In the planning of wide areas such as cities, countries, the metropolis, and the megalopolis, it is necessary to well arrange the geographical jurisdiction of local governments as a unit of region. The river water system, including small streams to large rivers, should be given its due share in the planning and jurisdictional delineation. The traditional concept of the local government's jurisdiction emphasizing the accessibility may be fading away. Instead, the efficiency of the public management would be the main concept in determining the jurisdiction of local governments. The river improvement, the waterworks, the sewage, the maintenance of water quality, the space of water recreation, are relatively important in the efficient management of that area. This paper argues for the equalization between the geographical jurisdiction of local governments and watersheds. To this end, I do case studies of the local governments areas such as Ri(里), Eup Myon(邑 面), Si Gun(市 郡), KyangyokSi Do(廣域市 道). The study interprets ARS will be one of the principles of land use and the reorganization of the local jurisdiction in the future as a geo-systematic and the eco-systematic criteria.

This study analyzed a survey of residents' awareness of rivers and water spaces that reflected residents' awareness in order to establish a basic park green space plan. Through this, the perception and requirements of rivers and water spaces were analyzed and important information was provided for urban planning and environmental management. As a result of analyzing residents' neutral satisfaction with rivers and their opinions on the frequency of use, role, and purpose, it was confirmed that rivers are recognized as an important part of urban life and contain the potential for development for a better urban environment. . However, considering the dissatisfied response and the relatively low frequency of use, we came to the conclusion that better urban planning and management is needed to meet the needs of residents by improving the river environment and providing various facilities. Based on this, city managers should focus on river management and improvement by actively collecting residents' opinions. Through analysis of the causes of dissatisfied responses, measures such as improving the environment around rivers and waste management should be prepared, and a broad strategy for environmental conservation and utilization should be established by reflecting the diverse expectations and demands of residents. These ongoing efforts are expected to have a positive impact on the sustainability of the city and improvement of residents' quality of life. Additionally, the results of this study will be able to contribute to establishing policies for urban planning and environmental improvement through similar research and analysis in other regions.

현재의 하천구역구분은 평가자의 주관에 의해 경험적으로 보전, 복원 및 친수지구로 구분되고 있다. 보전지구를 구분할 때에는 하천의 자연성을 대상으로 하기 때문에 대부분 기술자들의 결과가 일치하지만, 복원지역과 친수구역을 구분할 때에는 도시하천과 전원하천이 혼재하는 경우 그 구분의 기준을 정하기기 어려운 실정이다. 따라서 본 연구에서는 하천구역을 구분하기 위해 우선 보전지구 정비지구로 구분하고 정비지구를 다시 복원지구와 친수지구로 구분하고자 한 기존 연구(송주일과 윤세의, 2008)의 적용성을 확인하기 위하여 경기도지역을 중심으로 20개 도시하천의 46개 구간, 29개 전원하천의 47개 구간, 19개 산지하천의 48개 구간 등 총 141개 구간에 대하여 평가를 수행하였다. 본 연구의 결과는 하천구역구분에서 보전지구, 복원지구 또는 친수지구를 구분하는데 합리적임을 알 수 있었다. 정량화된 기준에 따라 하천을 보전, 복원 및 친수지구로 지정할 수 있는 가능성을 제시하였다.

Today, a trend that tries to return the artificial space of a river to a natural one is expanding. But in Korea, which lies in the monsoon climate zone, rivers endure flood damage every year. Moreover, climatic change from global warming causes severe variations in precipitation patterns. Until recently, river restoration practices in Korea have followed partial restoration. These restorative treatments transformed artificial structures of the stream to natural ones and introduced natural vegetation by imitating natural or semi-natural streams. Treatment transformed the riparian structure and increased the diversity of micro-topography and vegetation. Furthermore, restoration recovered species composition, increased species diversity, and inhibited the establishment of exotic species. In particular, the Suip stream, which was left to its natural process for approximately 50 years, recovered its natural features almost completely through passive restoration. An urban stream, the Yangjae, and a rural stream, the Dongmoon, were restored partially by applying ecological principles. On the contrary, technological treatment applied to recover flood damage induced species composition far from the natural vegetation and decreased species diversity. Additionally, this treatment increased exotic species. The same results were found also in benthic invertebrate and fish fauna. The above-mentioned results reflect the importance of ecological considerations in river management.

The purpose of this study is to analyze the Tetsugakudo Kouen Collective Housing Development Project in Japan. Project implemented cooperatively by the Tokyo Metropolitan Government in charge of river management, Shinjuku and Nakano-ku responsible for park management, and the UR, a housing project developer. This project set a significant precedent for three-dimensional river use by realizing the three-dimensional integrated development of a flood control reservoir, a park, and collective housing. The major effectiveness of this project can be summarized into four points. 1) The costs borne by individual project developers were significantly reduced by realizing a high degree of application and multipurpose use of the land through a joint project. 2) This project, which was designed to accommodate rainfall of 30 to 40mm per hour, is expected to contribute to reducing flood damage and generating significant investment effects, in terms of asset value in downstream areas, thereby increasing flood control security. 3) Local disaster prevention function were enhanced by providing an evacuation site in the case of an earthquake. 4) The living environment was improved by adding the function of a park.
