  • 본 연구에서는 지표수와 지하수를 최적 연계 운영하여 장차 다가올 물 부족에 대응할 수 있는 용수 공급 방안을 검토하였다. 최적 지표수, 지하수 연계운영 모형은 용수공급으로 인한 순편익을 최대화하도록 이산미분동적계획법을 사용하여 개발하였다. 시범유역으로 양양 남대천을 선정하여 모형을 적용한 결과, 지표수만 사용하여 용수를 공급하는 것에 비하여 용수공급 신뢰도가 뛰어남을 확인할 수 있었다.

  • 일반도시계획은 보편적이고 획일적인 건축행위를 제한하는 평면계획인 반면 지구단위계획은 필지, 가구, 획지단위 별로 차등을 두어 다양한 건축행위를 유도할 수 있는 입체적인 계획이다. 그러므로 단지계획을 위해서는 토지이용계획 등 2차원적인 토지정보뿐만 아니라 채광, 배수, 향 등의 분석을 위해 3차원적인 지형정보의 이용이 필요하다. 이러한 필요성을 충족시키기 위해 GIS 및 사진측량 기법을 이용하여 정보를 구축한다면 보다 합리적이고 효율적으로 단지계획을 수립할 수 있다. 본 연구에서는 테스트지역에 대해 GIS기법을 이용하여 단지계획을 위한 정보를 구축하였으며 위성영상과 DEM으로 대상지역의 3차원 모델을 구축하여 분석하였다. 연구결과 토지이용분석, 배향 분석, 수계분석, 경사분석을 실시하여 지구단위계획 수립에 효율적으로 활용할 수 있었다. 또한 분석결과를 반영하여 실제 대상지역에 대해 지구단위계획을 수립한 결과 적절하며 효율적임을 알 수 있었다.

  • 본 연구에서는 도시 특성변수와 도시계획시설 공급패턴의 상관성을 업무 담당자의 직무에 대한 견해와 다변량분석을 시행하여 도시관리계획 수립단계에서 사업의 효과를 극대화 할 수 있도록 자발적인 주민 참여와 의견을 행정에 반영하여 제도적으로 주민참여를 적극적으로 유도할 수 있도록 하였으며 도시계획시설의 공급특성에 따른 관리방안으로서 중요도와 효용성이 높은 시설인 도로, 공원, 상하수도 시설 동은 선계획 및 후개발 정책을 강화하고 효율과 형평의 요소를 조화시킬 수 있도록 정부의 서비스 공급을 축소하고 민간서비스가 가능한 행정에 대해서는 민간참여를 확대해 나가는 관리방안이 필요하고 향후 효율적인 도시관리를 수행하기 위해서는 공공서비스의 공급 수행을 정부가 공급하는 확대지향적인 성향을 억제하고, 민간참여를 위축하는 각종 규제를 대폭 완화하여 민영화를 확대하는 방향으로 법과 제도를 보완하는 도시계획시설의 관리방안 체계를 구축해야 한다는 결과를 얻을 수 있었다.

  • Water quality in Lake Rotorua, New Zealand, deteriorated since the 1960s because of excessive phytoplankton growths due principally to increasing nitrogen and phosphorus in the lake waters. Nutrient concentrations in eight of the nine major streams feeding Lake Rotorua have increased since 1965. The groundwater system has a key role in the hydrology of the Lake Rotorua catchment and the groundwater system is probably the control on the time delay between intensification of agricultural land use and response of surface water quality. All major, and many minor streams, in the catchment are fed by springs. Two lithological units are most important to groundwater flow in the Lake Rotorua catchment: Mamaku Ignimbrite, erupted in about 200,000 years ago and Huka Formation sediments which filled the caldera left by the Mamaku Ignimbrite eruption. Rainfall recharge to groundwater in the groundwater catchment of Lake Rotorua is estimated as approximately 17300 L/s. A calibrated steady-state groundwater flow model estimates that approximately 11100 L/s of this flow discharges into streams and then into the lake and the balance travels directly to Lake Rotorua as groundwater discharge through the lake bed. Land use has impacted on groundwater quality. Median Total Nitrogen (TN) values for shallow groundwater sites are highest for the dairy land use (5.965 mg/L). Median TN values are also relatively high for shallow sites with urban-road and cropping land uses (4.710 and 3.620 mg/L, respectively). Median TN values for all other uses are in the 1.4 to 1.5 mg/L range. Policy development for Lake Rotorua includes defining regional policies on water and land management and setting an action plan for Lake Rotorua restoration. Aims in the action plan include: definition of the current nutrient budget for Lake Rotorua, identification of nutrient reduction targets and identification of actions to achieve targets. Current actions to restore Lake Rotorua water quality include: treatment of Tikitere geothermal nitrogen inputs to Lake Rotorua, upgrade of Rotorua City sewage plant, new sewage reticulation and alum dosing in selected streams to remove phosphorus.

  • Tan-Sui River Basin covers Taipei metropolitan area of 2,726 square kilometers with more than six million residents. Since 1988, Taiwan government started to plan and construct an integrated sewerage system, consisted by both separated and concentrated trunk sewers, wastewater treatment plants and ocean outfalls. This presentation will introduce the master plan and major facilities of Tan-Sui River Basin sewerage system. Other measures to protect general water quality and the environment of adjacent river basin area of Tan-Sui River and her tributaries by Taiwan EPA will be presented as well.

  • This study aims to presents the applicability of apartment building for renewable energy systems using method of uncomplicated calculation and computer simulation. According to the weather conditions (NASA Surface meteorology and Solar Energy) analysis, it has been found that photovoltaic and wind power system can be applied to apartment buildings application. In case study considering layout and block plan, adaptation of solar water heating, photovoltaic and wind energy system to apartment buildings was proved to produce a profit. And the application strategies of renewable energy systems can be used not only for the investment decisions for economic analysis but also for the comparative analysis of uncomplicated calculation and computer simulation.

  • In this study, we have developed algorithms to find more effective solutions for compensatory decision-making problems in the case of the decision maker with fuzziness which can occur in a real world fuzzy environment. We have applied the algorithm to the problems related to the structural reform of the capital and the number of workers in the local industry. We have selected Taegu city for this study. In this study, we have determined the capital and the number of workers, satisfying maximum productivity and minimum air and water pollution under the constraints such as capital-labor ratio, the demand for land and water and the fluctuation of the capital and the number of workers. The determined capital and the number of workers could improve the competitive advantage of Taegu city and could be utilized as criteria for the compilation of the budget, determination of policy for supporting plan of companies, the forecast of number of workers and the training plan of workers.
