Scour is a natural process in rivers initiated by the erosive action of the activated water. Spur
dikes are built across the flow to defend the stream erosion and facilitate the shifting of the …

In fluvial sedimentology, bed sediment entrainment by streamflow has a decisive role in
controlling several fluvial processes. Owing to its huge practical importance, the subject has …

Inorganic sediment is not the only solid‐fraction component of river flows; flows may also
carry significant amounts of large organic material (ie large wood), but the characteristics of …

Random walk models of fluvial sediment transport recognize that grains move intermittently,
with short duration steps separated by rests that are comparatively long. These models are …

Arid and semi-arid regions face multiple problems in terms of water management,
particularly where surface water is a primary resource. On the northern flank of the High …

Bed particle entrainment by turbulent wall-shear flow is a key topic of interest in
hydrodynamics because it plays a major role to govern the planetary morphodynamics. In …

Die praktische Umsetzung der Vorgaben der EG-Wasserrahmenrichtlinie (EG-WRRL) in den
Nationalstaaten ist seit der 4. Auflage dieses Buches im Jahre 2010 weiter fortgeschritten. In …

The paper reports on three direct numerical simulations of sediment transport with different
prototypical non-spherical particle shapes, ranging from prolate to oblate to a triaxial …

The flow within an oscillatory boundary layer, which approximates the flow generated by
propagating sea waves of small amplitude close to the bottom, is simulated numerically by …

Geologists, physicists, and mathematicians have studied ripples and dunes for more than a
century, but despite considerable effort, no general model has been proposed to explain …
