Abstract

There are many pilot programs and projects to implement the water quality trading (WQT) policy. But actual trading is relatively rare. The main reason of the scarce applications of WQT policy is the difficulty in determining the equalities between the trading sites. The uncertainty of the impacts of the nonpoint sources pollutant discharges between up and downstream urban development areas also makes the implementation of the policy harder. The simulated results from the watershed modeling program will be used to calculate the point and nonpoint sources pollutants of the future urban development scenarios. The amount of suspended sediments resulting from the urban developments and rainfall intensities will be used to indicate the environmental impacts of the water body between upstream and downstream. The water quality impacts after development scenarios to the outlet of the watershed were transferred to the trading units between two sites. The recommended trading units can be used as a decision support system for policy makers and stakeholders to carry out better WQT practices.

미국의 수질교환법의 제정 이후 이 법안의 적용을 위하여 많은 파일럿 프로그램과 프로젝트가 생성되었으나 실제로 수질교환이 이루어 지는 경우는 흔치 않은 현실이다. 수질교환법의 적용이 용이하지 않은 이유로 가장 큰 것은 교환 지역 양측 간의 공정성을 확보하기가 쉽지 않기 때문이다. 또한 도시개발로 유발되는 비점오염원의 유출량으로 인한 하천의 환경영향의 불확실성이 정책입안자의 법안 적용을 더욱 어렵게 하고 있다. 본 논문은 수질 모델링 프로그램 중 도시의 불투수면의 유출을 모의하기에 유용한 Hydrological Simulation Program-Fortran (HSPF)을 이용하여 미래의 도시개발 시나리오에 대응하는 점오염과 비점오염원 유출량을 도출하였다. 도시개발의 정도와 강우강도에 따른 부유탁도의 증가분을 계산 함으로써 향후 도시개발이 미치는 수질 영향을 하천 상 하류 간의 수질교환 단위로 전환하여 제시하였다. 제시된 지역 특화된 수질교환단위는 정책입안자와 이해관계자들에게 수질교환법 적용을 위한 정책결정 시스템으로 사용될 수 있다.
