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 Sediment Transport and Landform at Channel Confluence
Author : Tonghuan LIU, Beiling FAN, Xiaoyong LIAO and Gerald C. Nanson
River channel confluences form important morphological elements of every river system. In this paper, on the basis of previous studies, the evolutions of flow-sediment on siltation and erosion characteristics at channel confluence with different confluence patterns were studied. Research results showed that, the characteristic of flow-sediment movement at channel confluence between the scour test and deposit test was in substantial agreement same with the condition of same confluence angle and same sand-feeding, but the channel morphology at channel confluence which strongly depended on the flow and sediment conditions from the tributary and the relationship between main and tributary rivers, as far as hydraulic factors were concerned was very different.
