Analysis of Water bady Damage at Osu Stream Using the Flow-Loading Equation and 8-Day Intervals Cumulative Flow Duration Curve

Analysis of the Water Quality Characteristics of Urban Streams Using the Flow–Pollutant Loading Relationship and a Load Duration Curve (LDC)

“…An LDC is a curve that shows the relationship between the measured water quality data under all flow conditions. It makes it easy to interpret water quality phenomena while considering flow characteristics and is useful when seeking appropriate water quality management measures by analyzing and diagnosing the intrinsic characteristics of the water pollution problem and for areas that exceed the target water quality [7]. Recently, it has been used as a method for analyzing the degree of damage to a water body under various flow conditions to overcome the limitations of the TMDL program at the reference flow, i.e., the specific flow condition averaged over the last decade [11].…”

“…To address this problem, the Ministry of Environment (ME; Rep. of Korea) implemented the total maximum daily load (TMDL) program on the Nakdong River in 2004. Since the water quality and flow are measured simultaneously by the TMDL monitoring network, unlike the conventional water quality monitoring network, it is possible to quantify the pollutant load from the flow [7]. The TMDL program of South Korea is managing to achieve the target water quality at the reference flow, which involves specific flow conditions averaged over the past decade.…”

“…The TMDL program of South Korea is managing to achieve the target water quality at the reference flow, which involves specific flow conditions averaged over the past decade. Therefore, there is a limitation for managing the water quality using TMDL for the various flow conditions [7].…”

“…Lee et al evaluated the organic matter load contained in the streams flowing into Masan Bay using the flow-pollutant loading equation and thus classified the pollution sources of each stream [10]. Lee et al investigated the outflow characteristics of pollutants subjected to the TMDL program and the degree of water quality deterioration by section and season under flow conditions, using discharge and water quality data in the Seomjin River [7].…”
