The Saru River is known for transporting large quantities of sediment during flood. Sediment transport observation was conducted during the flood in 1997 at several stations, from the river mouth to upstream of the reservoir. A numerical model to calculate sediment transport rate, grain size of bed material, and bed elevation is developed. The calculated sediment transport rate is compared with the observed results and the validity of the model is confirmed. It is suggested that the model can be a powerful tool for the long-term prediction of the river bed environment changes including the effect of the dam construction.Read More
