Keywords: Sediment transport bed sediment total sediment load discharge versus total sediment load
Abstract: Korean rivers are relatively steep and have a high ratio of maximum and minimum discharges. Moreover, high flows are concentrated in the summer, the rainy season. This makes the prediction of sediment transport in Korean rivers very complicated. This study presents the characteristics of the total sediment load in the Han-gang River, Korea. The total sediment load data collected in the period of 2006-2019 by Korea Institute of Hydrological Survey are used. First, the relationships between the total sediment load and discharge are presented by year. Then the formula that best-fits to the data, is proposed to predict the total sediment load among existing formulas. This study will be useful for predicting the sediment transport in rivers, which will be more important due to climate change.
