The evolution and characteristics of large-scale vortices are critical for understanding
temporal and spatial exchange of mass and momentum. Using a validated depth-averaged …

One‐dimensional models for river bifurcations rely on a nodal point relation that determines
the distribution of sediments between the downstream branches. The most widely‐adopted …

Morphological processes in sand‐bed braided rivers are highly complicated and dynamic,
and it is challenging to fully comprehend and predict them quantitatively or even …

Discharge unsteadiness plays a key role in the dynamics of alternate bars, however, how
migrating alternate bars determine their shape under unsteady discharge conditions …

The amount of sediments transported by a river is difficult to estimate, while this parameter
could influence channel geometry. It is possible to derive the bedload transport rate per unit …

Climate change is expected to alter the distribution of flow discharge in rivers worldwide. We
study the impact of climate‐driven flow changes on the shape of riverbed, and specifically on …

A new empirical equation for free alternate bar length at the fully developed state is
introduced. The equation is developed on the basis of dimensional analysis and all readily …

Understanding the dynamics of fine sediment stocks in the riverbed is important for river
management. However, this dynamics is size dependent (the sand fraction against the silt …

The mechanism of sandbar initiation and formation is unresolved. The occurrence of
sandbars has been investigated using stability analysis, which assumes that sandbars occur …

This study investigates the occurrence and dynamics of single row alternate bars forming in
a particular reach of the sand bed Elbe River in Germany. Although the formation and …
