Determination of standard target water quality in the Nakdong River basin for the total maximum daily load management system in Korea
Abstract This study suggests methods to improve the total maximum daily loads management system currently being regulated in Korea. The TANK model which is a conceptual rainfall-runoff model including the river routing function and the evapotranspiration process is adapted to simulate daily stream flows, and the 7-parameter log-linear model combined with the minimum variance unbiased estimator is used to calculate daily stream contaminant loads. Based on these methods, Load Duration Curves (LDCs) for each unit watershed are constructed. Using LDCs of all unit watersheds, representative specific LDC of Nakdong River is derived to indicate the average contaminant status of the whole river basin in terms of water quality items. Using representative specific LDCs, appropriate target water qualities with respect to reference flow conditions are assigned to all of unit watersheds, and point sources or non-point sources priority management areas of 40 unit watersheds of the Nakdong River basin are identified.
