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.

From white rivers to green rivers ¨c why and how are they changed?
Many rivers in the world including Korea are being changed from ¡°white¡± rivers to ¡°green¡± rivers, i.e. from the rivers with white sand/gravel-covered riparian lands to those with green vegetation-covered ones. These changes sometimes cause a serious engineering problem of increases in flood hazard by increases in flow resistance and fixation and heightening of riparian lands. In some cases, on the other hands, they can support more diverse species with diverse environment of riparian habitats as compared with monotonous white sand and gravel rivers. This study reintroduces the patterns of causes for the succession of ¡°white¡± riparian lands to ¡°green¡± vegetation-covered ones. Another possible cause due probably to change in the rainfall pattern in recent years is suggested as a new cause. This new possible cause might be a result of climate change.
