Abstract: To clarify the contributing factors for the river-bed variations, numerical simulation and statistical analysis were conducted. The study site is the Yoshino river mouth, Shikoku island, Japan. At first, under the unsteady flow condition, 1-D numerical simulations on river-bed variations were carried out and the results of them were in agreement substantially with the surveying data. Secondary, empirical eigenfunction were applied to the simulation results and surveying data, respectively. Finally, contributing factor for river-bed variations are estimated by principal component analysis.
