  • 기후변화가 지역의 수자원에 영향을 미칠 것으로 예상됨에 따라 수자원 관리자들은 이에 대응한 적응전략을 수립하는 것이 필요하다. 이에 본고에서는 미국, 영국, 캐나다, 오스트렐리아, 네덜란드의 적응관리의 실태를 검토하였다. 이들 나라들은 현재의 수자원 관리관행, 제도적 장치, 기후변화의 잠재적 수자원 영향에 따라 매우 상이한 적응관리를 하고 있다. 이들 나라들의 비교연구를 통하여 기후변화에 따른 한국에서의 지속 가능한 수자원 관리를 위한 정책적 관련성을 도출하였다.

  • Most urban water management systems are becoming vulnerable to flooding and drought due to the climate change (CC), urbanization and energy shortage. Despite of poor water management circumstances caused by extremely uneven annual rainfall and hilly terrain, traditionally we have made a sound and sustainable life based on our own philosophy and technologies which copes with our rigid environment. In this study a new paradigm of rainwater management is suggested and multipurpose and creative rainwater harvesting and management (RWHM) systems are introduced providing several case studies such as rainfall storage drainage (RSD) system, rainwater infiltration facilities and star city RWHM system. This new RWHM paradigm leads Seoul Metropolitan Government (SMG) in the Republic of Korea to change regulations and politics for the integrated RWHM. Finally, RWHM is expected to improve the safety, efficiency, energy consumption of urban water infrastructure, to reduce urban heat island phenomenon and, furthermore, to contribute in finding solutions for worldwide water issues and to adapt CC.

  • The uses of multi-dimensional hydrodynamic and water quality models are increasing to support a sustainable management of large dam reservoirs in Korea. Any modeling study requires selection of a proper spatial dimension of the model based on the characteristics of spatial variability of concerned simulation variables. For example, a laterally averaged two-dimensional (2D) model, which has been widely used in many large dam reservoirs in Korea, assumes that the lateral variations of hydrodynamic and water quality variables are negligible. However, there has been limited studies to give a justification of the assumption. The objectives of this study were to present the characteristics of spatial variations of water quality variables through intensive field monitoring in Daechung Reservoir, and provide information on a proper spatial dimension for different water quality parameters. The monitoring results showed that the lateral variations of water temperature are marginal, but those of DO, pH, and conductivity could be significant depending on the hydrological conditions and local algal biomass. In particular, the phytoplankton (Chl-a) and nutrient concentrations showed a significant lateral variation at R2 (Daejeongri) during low flow periods in 2008 possibly because of slow lateral mixing of tributary inflow from So-oak Stream and wind driven patchiness.

  • 세계 5대 갯벌해역으로 유명한 한국 서해 경기만의 기후변화 영향을 파악하고, 기후변화 영향을 최소화하기 위한 적응방안 연구하였다. 경기만의 기후변화 영향으로 2100년에 수온은 1.2 ℃ 증가하고, 염분이 1.1 PSU 감소하며, 해수면은 35.2 cm 상승하는 것으로 예측되었다. 또한 해수면 상승의 효과로 150.5 km2의 해안지역이 침수될 것으로 예상되었다. 기후변화로 인한 경기만 생태환경 영향을 최소화하기 위한 적응대책으로는 1) 경기만 자체 자연환경의 적응능력 유지를 위한 지원, 2) 생물 서식지 확보를 위한 인간 활동 조정 등 두가지 방안이 제시되었다.

  • Sustainable use of water resource and conservation of water quality are essential problems in the world. Especially, problems of water quality are serious one for human health as well as ecological system of all creatures on the earth. Recently, the importance of total effluent load as well as the concentrations of pollutant materials has been recognized not only for the conservation of water quality but also for sustainable water use in watersheds. However, the measurement or estimation of total effluent load from non-point source area such as farm lands or forests may be more difficult because both of concentration and discharge of the water are greatly changed depending on various factors especially metrological conditions such as rainfall, while the measurement from a point source area may be easy because the concentration of pollutant materials and amount of discharge water are relatively steady. Therefore, the total effluent load from a non-point source is often estimated by statistical relationships between concentration and discharge, which is called as L-Q equation. However, a lot of work and time are required to collect and analyze water samples and to get the accurate relationship or regressive equation. So, we proposed a new system for direct measurement of total effluent load of water quality from non-point source areas to solve the problem. In this system, the overflow depth at a hydraulic weir is measured with a pressure gage every hourly interval to calculate the amount of hourly discharge at first. Then, the operating time of a small electric pump to collect an amount of water which is proportional to the discharge is calculated to intake the water into a storage tank. The stored water is taken out a few days later in a case of storm event or several weeks later in a case of non-rainfall event and the concentrations of water quality such as total nitrogen and phosphorous are analyzed in a laboratory. Finally, total load of the water quality can be calculated by multiplying the concentration by the total volume of discharge. The system was installed in a small experimental forestry watershed to check the performance and know the total load of water quality from the forest. It was found that the system to collect a proportional amount of water to actual discharge operated perfectly and a total load of water quality was analyzed accurately. As the result, it was expected that the system will be very available to know the total load from a non-point source area.

  • The purpose of this study is to propose a way to develop and disseminate the renewable energy technologies and industries in the local community. Fundamentally, the renewable energy is able to reduce environmental pollution and diminish a use of fossil-fuel energy in the local area. And it will lead to promoting regional sustainable energy in the future, as well as making contributions to local economic development. Above all, based on the environmental conservation project, including greening of the city and improving water quality, Daegu metropolitan city has launched a series of renewable energy projects, such as solar city programs and local energy plan. But, some problems still exist, due to the technological, economic and socio-political barriers. Thus, to encourage and disseminate a renewable energy in Daegu city, we need to examine a present condition on renewable energy and analyze constraint elements to prevent its distribution. Based on the results, we have to set the feasible strategy to develop and disseminate renewable energy in Daegu city and help it systematically integrate renewable energy technologies and industries into environmental economics and city planning. Ultimately, to achieve this purpose, we need to adopt the following policy measures: (1) establishment of a master plan for renewable energy; (2) interconnection between local development project and energy industry; (3) promotion of technological development; (4) inducement of and assistance to renewable energy industry; (5) fostering venture companies; (6) specializing Daegu's public office by energy-specific education programs. In particular, local entities including local company, consumers, policy-makers and citizen's groups have to pay attention to local energy plan for the regional sustainable energy future. These measures will lead to establishing an environmentally friendly and sustainable city.

  • Pungsu is can be seen as an ecological architectural science regarding native natural environment of east asia. Even though the language used in Pungsu is different from that of ecological architecture, Pungsu considered the surrounding environment of the traditional house by various Pungsu method for making and keeping more healthy life and sustainable environment. The research is for finding out how the surrounding natural environment was considered with Pungsu, a traditional ecological architectural science in case of site selection and planning house by the confucian scholar in Joseon period. Myungjae Yunjung traditional house of Nonsan in the middle of korea is selected. He is one of the greatest confucian scholar in Joseon period. The study is processed as follows. Feature of mountain expressed as dragon and four important hills of the house are analyzed in chapter 2, Water environment is studied and the geomantic landscape are analyzed by shape theory called Hyung-guk-Lon in chapter 3, 4. Finally Pungsu applied in architectural space is analyzed in chapter 5.
