  • 본 연구는 도시개발로 인하여 농촌에서 도시로 급격한 토지이용 변화를 겪은 신도시 지역의 수문변화 예측과 저감방안 도출을 목적으로 하였다. 대표농도경로(Representative Concentration Pathway, RCP) 기후변화 시나리오로 2100년까지 분석결과 강수량 증가가 유출고 증가에 직접적으로 기여함을 알 수 있었다. 기후변화와 함께 도시 용지 형태도 저영향개발(Low Impact Development; LID) 기법으로 적용한 식생체류지의 효율에 영향을 미쳤다. 서로 다른 도시 시설 용지를 결합하면 각 시설 용지 별 차이가 있는 저류 가능 강수량을 보완할 수 있고 첨두유출량 경감과 도달시간 지체를 유도할 수 있어 도시개발로 인한 수문 영향을 완화시킬 수 있는 새로운 접근이 될 수 있음을 제시하였다.

  • Recently, many studies on air quality prediction models have been performed to develope new ones. The purpose of the study is to obtain a method to predict $SO_2$ concentration simply in urban area using hour-to-hour meteorological data such as the wind speed, the incoming solar radiation, and the cloud coverages. The relationships between with speed and $SO_2$ concentrations are plotted in flgures. Predicted concentration curves are obtained for equation C=b/(1+au).

  • Noise map is becoming an increasingly important tool supporting noise policy. In order to main am a quiet environment of urban areas, noise map was developed by using GIS technique which combines geographic and noise informations with a database management system. By evaluating various methods of the spatial anal: sis, it was concluded that the inverse distance weighted method gave the best results and was applied to develope the noise maps of road noise.

  • In Korea, an environment-friendly concept of "rain re-cycling" was initially introduced in apartment complex planning and designs in the late 1990s. Although its application cases are extremely few, with the growing importance of rainwater utilization, introduction of rainwater management facilities in urban areas began to drawn keen attention. In urban areas also, plans to introduce rainwater management facilities in apartment complexes as infrastructure improving living environment, such as sewage treatment facilities are very urgently required. In order to introduce rainwater management facilities as infrastructure in an apartment complex, apartment complex cases that had introduced the facilities were reviewed first. In this study, a few applied rainwater management facilities in an apartment complex were surveyed(Infiltration barrel, Rubble porosity storage tank, Underground storage tank). As a result, problems in introducing rainwater management facilities in apartment complexes in Korea were identified.

  • For resource Recycle society, the Ministry of Environment is recently propeling the introduction of MSW(Municipal Solid Waste) pretreatment facilities(MBT) from advanced country such as Germany. On the basis of this, The Ministry of Environment plans to expand all over the country after the adaption of wide area style(Sudokwon landfill : 200 ton/day), urban communities style(Bucheon City : 90 ton/day), Semi-urban(Gangreung City : 150 tons/a day), farm village style (Buan : 30 ton/day).

  • Urban residential redevelopment policies have inevitably been bound up with issue of conflicts among renewal associatios, local government and developer. The purpose of paper is to examine the causes of conflicts through four residential environment redevelopment projects. In result for the successful redevelopment projects, strategies for citizen paticipation program and relocation should be set up.

  • Non-point source pollution management is one of the most important issues in Korean water quality/watershed management. In recent years, Low Impact Development (LID) has emerged as an effective approach to control stormwater in an urban area. This study illustrates how to design and evaluate the effect of non-point pollutant management using EPA-SWMM LID module and suggests design parameters for modeling LID facilities. In addition, optimal installation locations of LID can be determined by a simple distributed hydrologic model by using SWMM for a long-term.

  • The main contents of revision of the rural landscape planning according to Landscape Law discussed in this study show that the urban landscape and rural landscape have a propulsion system which integrate them into the national landscape and manages through the landscape planning. However, management and conservation reflecting the fundamental difference between urban and rural areas are needed. Planning the landscape by generalizing the size of the population, administrative district, the surface area does not meet the ultimate purpose of the Landscape Law that tries to establish differentiated local landscapes. Therefore, the association of professionals who can support and establish a propulsion system for landscape planning with the consideration of regional characteristics. For the urban landscape, the landscape committee is fulfilling the role, but none is available for the rural areas. This study is mostly based on previous literatures, however, in the future, it is desirable to have selected pilot areas for different landscape types and review problems that may occur during the application and process, in order to establish the landscape guidelines for the rural landscape plan.

  • In this study, Urban Climate Simulation was performed by 3-Dimensional Urban Canopy Model. The characteristics of urban climate was analyzed combining artificial land coverage, building size, heat production from the air conditioning and topographic conditions as physical variables which affects urban climate characteristics. The results are as follows. (1)The aspects of the urban climatal change is derived to be related to the combination of the building coverage ratio, building height and shading area. (2)Whole heat generation was influenced by the convective sensible heat at the lower building height and by the artificial heat generation at the higher one over 20-story building influence to some extent of the building coverage ratio. The effect of the altitude is not more considerable than the other variables as below $1^{\circ}C$ of the air temperature.
