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.

Study on numerical simulation of morphodynamic processes of braided rivers
Author : JIAN SUN(1) & BINLIANG LIN(2)
ed river is a river pattern with complex planform appearances and dynamic evolution properties, which contains a
network of multi-thread streams that split off and re-join each other. Both the cellular models with reduced-complexity method
and physical-based models have been attempted to simulate the dynamic processes of braided channel patterns. In these
models, perturbations were widely introduced into the initial or boundary conditions. The effect of disturbance in the
development of braided pattern has not been clear so far, although there are disturbances existing in real world, such as
uneven sandy bed and the uncertain arrangement of sands. In this study, a physical-based model is set up and applied to
simulate the braided channels. It is found that the artificial disturbance is not a necessary prerequisite in the generation of
braiding pattern but it changes the channel evolution processes. The impacts of the disturbance on the channel development
are further investigated. :Publishe
