Abstract
For effective management of water quality on the southern coast of korea, a three-dimensional eco-hydrodynamic model is used to predict water quality in summer and to estimate the reduction rate in pollutant loads that would be required to restore water quality. Under the current environmental conditions, in particular, pollutant loadings to the study area were very high, chemical oxygen demand (COD) exceeded seawater quality criteria to comply with current legislation, and water quality was in a eutrophic condition. Therefore, we estimated reduction rates of current pollutant loads by modeling. The model reproduced reasonably the flow field and water quality of the study area. If the terrestrial COD, inorganic nitrogen and phosphorus loads were reduced by 90%, the water quality criteria of Region A were still not satisfied. However, when the nutrient loads from polluted sediment and land were each reduced by 70% simultaneously, COD and
한국 남해의 연안역(진해만에서 부산연안)에 있어서 효율적인 수질관리를 위해서, 3차원 생태-유체역학 모델을 적용하여 하계 수질을 예측하고, 목표 수질회복을 위한 오염부하 삭감량을 산정하였다. 현재의 오염부하량 조건하에서 연안해역의 수질(화학적 산소요구량과 영양염류 농도 등)은 설정된 해양환경수질기준을 초과하였고, 또한 부영양화 상태에 있기 때문에 유입하는 오염부하량의 저감이 필요하였다. 이러한 배경하에서, 모델이 적용되어 보정과 검증과정을 통해 연구해역의 유동장과 수질 분포를 유사하게 모의하였다. 시나리오 분석결과, 진해만 해역은
