Influence of Bed‐Load Transport on Flow Resistance of Step‐Pool Channels
This study investigates the influence of bed‐load transport on flow resistance and bed stability in steep step‐pool channels. A total of 86 flume experiments was performed.

Movement of sediment over periodic bed [PDF]
The movement of bed load along the closed conduit can lead to a loss of stability of the bed surface, when bed waves arise at the bed of the channel. Investigation of the development of bed waves is associated with the possibility of determining of the ...

Estimating sand bed load in rivers by tracking dunes: a comparison of methods based on bed elevation time series [PDF]
Quantifying bed-load transport is paramount to the effective management of rivers with sand or gravel-dominated bed material. However, a practical and scalable field methodology for reliably estimating bed load remains elusive.

A model for fluvial bedrock incision by impacting suspended and bed load sediment [PDF]
A mechanistic model is derived for the rate of fluvial erosion into bedrock by abrasion from uniform size particles that impact the bed during transport in both bed and suspended load.

Bed load sediment transport and morphological evolution in a degrading uniform sediment channel under unsteady flow hydrographs [PDF]
Flume experiments are conducted to investigate the intrinsic links between time-varying bed load transport properties for uniform sediments and bed surface morphology under unsteady hydrograph flows, in the absence of upstream sediment supply.

The morphodynamics of a swash event on an erodible beach [PDF]
A high-accuracy numerical solution, coupling one-dimensional shallow water and bed-evolution equations, with, for the first time, a suspended sediment advection equation, thereby including bed and/or suspended load, is used to examine two swash events on

Modeling of sand-gravel bed evolution in one-dimension [PDF]
In the paper the model for a one-dimensional non-equilibrium riverbed process is proposed. The model takes into account the suspended and bed-load sediment transport. The bed-load transport is determined by using the original formula.

Controls on the rates and products of particle attrition by bed-load collisions [PDF]
River rocks round through the process of impact attrition, whereby energetic collisions during bed-load transport induce chipping of the grain surface. This process is also important for bedrock erosion.

Flood flow characteristics and bed load transport in non-vegetated compound straight channels [PDF]
Floods are the most common natural disasters in Malaysia and have damaged structures, infrastructures, crops and even causes fatalities. It may also lead to erosion and sedimentation in rivers and this will result to complex river behaviour.

Riverine transfer of heavy metals from Patagonia to the southwestern Atlantic Ocean [PDF]
The occurrence and geochemical behaviour of Fe, Mn, Pb, Cu, Ni, Cr, Zn and Co are studied in riverine detrital materials transported by Patagonian rivers.
