The TMDLs(Total Maximum Daily Load) divides the water system into unit watersheds and allocates the total amount of pollutants. And it evaluates the water quality at the target water quality point. Flow data and water quality data surveyed through the water quality monitoring network, that are important to quantify the status of pollutants in the watershed and determine the cause. In this study, Use of flow data and water quality data at the target water quality point and small stream in the unit watershed of the Tamjin river basin calculates the pollutant load and evaluates the contribution rate of the target water quality point. In addition, the correlation between the contribution rate and the load of each grade was evaluated by dividing size of the measured flow rate. As a result, pollutant delivery ratio of pollution in the unit watershed of the Tamjin river increased with the increase of the flow rate. In some flow rate grades, Delivery ratio was high in certain flow rate grades due to the influence by inflow quantity. In order to analyze contribution rates of pollutants in the future, it is necessary to study pollutant emissions by rainfall and background concentration of pollutants.
