▪ Abstract Avulsion is the natural process by which flow diverts out of an established river
channel into a new permanent course on the adjacent floodplain. Avulsions are primarily …

Avulsion, ie the relatively sudden displacement of a river channel, has an important effect on
sediment distribution and on architecture of fluvial deposits because avulsion is a primary …

One of the most dramatic events in river environments is the natural diversion, or avulsion, of
a channel across its floodplain. Though rarely witnessed, avulsions can cause massive …

River bifurcations are critical but poorly understood elements of many geomorphological
systems. They are integral elements of alluvial fans, braided rivers, fluvial lowland plains …

There is as yet no rational basis for predicting the conditions leading to avulsion of a
meandering river. Here we present a conceptual model and quantify it under simplifying …

Avulsions are most characteristic of aggrading fluvial systems, but along the Klip River,
subhumid eastern South Africa, abandonment and re-establishment of meander belts occurs …

A mechanistic understanding of river avulsion location and frequency is needed to predict
the growth of alluvial fans and deltas. The Huanghe, China, provides a rare opportunity to …

Bifurcating rivers shape natural landscapes by distributing water and sediments on fluvial
plains and in deltas. Symmetrical bifurcations were often found to be unstable so that one …

At river bifurcations, water and sediment are divided over two branches. The dynamics of the
bifurcation determine the longterm evolution (centuries) of the downstream branches …

Rivers may dramatically change course on a fluvial plain. Such an avulsion temporarily
leads to two active channels connected at a bifurcation. Here we study the effect of dynamic …
