Abstract: In this study, the effect of rainfall events on the river¡¯s water quality was investigated. The study focused on Kangjung-Koryung Weir area of Nakdong river in Korea. Rainfall events greatly affected the water quality of study area since rainfall runoff may wash-out pollutants on surface near the river. Therefore, the proper stormwater management should be established to maintain desired water quality for the river. However, there were limits to obtain detailed precipitation data since the Korea Meteorology Administration provided rainfall data for a vast area. In our case, precipitation data for the whole city of Daegu was accessible, so detailed precipitation data for the study area could not be obtained. This limit made it difficult to analyze the exact effect of rainfall events on the water quality of the river. Measurements for precipitation around rivers should be installed to ensure the better stormwater management.
