AB - In the current Total Pollution Load Management system(TPLMs), the achievement of target water quality is evaluated using the average water quality over the past three years. However, this method has limitations as it does not reflect changes in water quality due to variations in flow rates, and it is inconsistent with the fundamental objective of TPLMs, which aims to achieve target water quality through pollutant load management. Therefore, this study proposes a method that enables the evaluation of target water quality achievement under various flow conditions based on pollutant loads. Using water quality and flow data, which are collected at eight-day intervals through the TPLM monitoring network, load duration curves (LDC) can be created. By utilizing this method, target water quality achievement can be assessed based on pollutant loads. Comparing evaluations for 21 sub-watersheds within the Geum River basin, target water quality achievement in 2023 was assessed by both the LDC method and the current three-year average method. The proportion of sub-watersheds exceeding the target BOD levels was 47.6%, 23.8%, and 19.0%, and for T-P, it was 57.1%, 23.8%, and 14.3% for each respective method. These results indicate that the LDC method yields relatively higher excess rates, showing that it provides a stricter evaluation of target water quality achievement compared to the current method The LDC method not only allows for the evaluation of target water quality achievement by considering flow variations but also is expected to be very useful when time-series predictions are required for target water quality assessments using dynamic models like watershed models, which are applied to estimate allocated loads.
