A new method for detecting spikes in acoustic Doppler velocimeter data sequences is
suggested. The method combines three concepts:(1) that differentiation enhances the high …

Rivers and Floodplains is concerned with the origin, geometry, water flow, sediment
transport, erosion and deposition associated with modern alluvial rivers and floodplains …

Data from laboratory flumes and natural streams show that the critical Shields stress for
initial sediment motion increases with channel slope, which indicates that particles of the …

Bed shear stress is a fundamental variable in river studies to link flow conditions to sediment
transport. It is, however, difficult to estimate this variable accurately, particularly in complex …

In 1883, Osborne Reynolds reported experiments in real viscous pipe flows and made the
seminal distinction between laminar or turbulent flow regimes, each with quite distinct flow …

A distinguished universal aspect of wall-bounded turbulent flows is Theodore von Kármán's
universal logarithmic law (log-law) of the wall, describing the time-averaged streamwise …

Vegetation is ubiquitous in river channels and floodplains and alters mean flow conditions
and turbulence. However, the effects of vegetation patches on near‐bed turbulence, bed …

Previous studies suggest that the seismic noise induced by rivers may be used to infer river
transport properties, and previous theoretical work showed that bedload sediment flux can …

The 3D instantaneous velocity recorded with an acoustic Doppler velocimeter (ADV) in a
highly turbulent free surface flow is analysed using several filters in order to eliminate the …

We introduce a new conceptual model for longitudinal and transverse diffusion of moving
bed particles under weak bed load transport. For both rolling/sliding and saltating modes the …
