본 연구에서는 댐 건설 사업을 추진하는 경우 발생되는 갈등사안 중에서 수문학적으로 접근하여 이수 및 치수에 대한 갈등 발생원인을 파악하고 이해당사자들의 직접적인 참여와 의견을 수렴하여 대안 모의와 결과를 도모할 수 있는 공영시각모형(SVM)을 개발하였다. 이수부문에서는 각 행정구역별 생활용수, 공업 및 농업용수 수요를 예측하고, 치수부문에서는 각 구조적 대안이 형성되는 경우 신속하게 모의하여 수위저감효과, 침수면적 및 피해액의 변화를 제시하여 상호의견 교환에 따른 합의점을 도출할 수 있도록 구축하였다. 이러한 공영시각모형의 이용은 정보공개의 정확성, 결과의 신뢰성 등을 확보할 수 있게 함으로써 댐 건설에 대한 갈등 조정 및 완화에 기여할 수 있을 것으로 사료된다.

When the Juam multipurpose dam which is connected with existing large water supply facilities is finished, water environment is changed from stream to lake. The changed quality of water should be examined. In this study, the result of water quality forecasting is analysed and an effective management plan of water quality is presented. In this study, the WASP5 model that is a dynamic water quality simulation model was selected to forecast the water quality. This model forecasts movement of change of pollutants. For an application of the model, the subject areas were divided into seventeen sub-areas by considering change temperature depending measuring points and on depth of water. Meteorological data collected by the meteorological observatory and data about quality measured by the Korea Water Resources Development Corporation were used for an operation of the model. As a result of quality examination through quality data and estimated pollutant loading, the water quality environment criterion was grade Ⅱ and the nutritive condition was measured as meso-graphic grade. In this study, an effective management was planned to improve water quality by reducing pollution load. According to the result of examination, when more than 30% of BOD was reduced it was recorded that the environment standard of water quality was improved to the second grade.
