효과적인 오염총량관리를 위한 데스크탑 기반의 LDC 평가 시스템 개발

초록

Load Duration Curve (LDC) can be used as a method for load management of point and non-point pollution source because the LDC easily assesses thewater quality corresponding to hydrological changes in a watershed. Recently, the application of LDC to total pollution load management is a growinginterest in Korea. In this regard, A desktop-based LDC assessment system was developed in this study to provide convenience to users in water qualityevaluation. The developed system can simply produce the LDC by using streamflow and water quality data involved in its database. Also, The system canquantitatively inform the success or failure of the achievement for a target water quality at monthly scale. Furthermore, seasonal water quality andpoint/non-point pollution load in a watershed can be estimated by this system. We expect that the developed system will contribute to establish local andnational policies regarding water management and total pollution load management because of its advantages such as the pollution tracking investigationand the analysis of water quality and pollution loading amount in an ungauged watershed.
