IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Analysis of factors which contribute to river-bed variation at yoshino river mouth
Author : Kohji UNO, Susumu NAKANO , Gozo TSUJIMOTO and Tetsuya KAKINOKI
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.
