Sediment sorting at the lee side of ripples, dunes and bars has already been recognized
long ago. A predictive model of the sorting is necessary but unavailable for implementation in …

Fan-shaped landforms occur in all climatic regions on Earth. They have been extensively
studied in many of these regions, but there are few studies on fans in periglacial, Arctic and …

Estuaries show dynamic patterns of channels and bars, which are also valuable habitats,
while channels provide access to harbours. In contrast with bars in rivers, we still lack …

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

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

Our objective is to understand general causes of different river channel patterns. In this
paper we compare an empirical stream power‐based classification and a physics‐based bar …

Incipient motion of particles on a river bed can, in principle, be understood and predicted
from a balance of the forces acting on the particles. On a natural river bed the exposure of …

Channel fills are common elements of Holocene river systems and older fluvial sequences,
but surprisingly little is known about formation and their sedimentary build‐up. Abandoned …

Granular materials avalanche when a static angle of repose is exceeded and freeze at a
dynamic angle of repose. Such avalanches occur subaerially on steep hillslopes and wind …

Classical deterministic bedload transport predictors are applied to sand-gravel bed rivers.
The turbulent bed shear stress is modeled according to a probability distribution to obtain …
