A model for fluvial bedrock incision by impacting suspended and bed load sediment [PDF]
Journal of Geophysical Research, 2008 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 Transport Equation on Arbitrarily Sloping Beds [PDF]
Journal of Hydraulic Engineering, 2008 This work presents a simple tool to evaluate bed-load transport intensity and direction on arbitrarily sloping beds with local longitudinal and transversal inclinations up to 25° and in the case of uniform sediments and low values of the applied Shields stress.

The role of velocity, pressure, and bed stress fluctuations in bed load transport over bed forms: numerical simulation downstream of a backward-facing step [PDF]
Earth Surface Dynamics, 2015 Bed load transport over ripples and dunes in rivers exhibits strong spatial and temporal variability due to the complex turbulence field caused by flow separation at bedform crests.

Geography, Environment, Sustainability, 2023 The development of bed load calculation methods directly depends on the reliability of the measurement data. The most reliable measurement data remains the data obtained by the volumetric method when observing the filling of reservoirs, borrows, ditches ...

The Study Impact of Effective Factors in Sediment Transport in Unsteady Flow [PDF]
مهندسی عمران شریف, 2022 The role of floods in sediment transport and river morphology has been proven. In this study, the effect of different parameters on the transfer of sediment bed load under flash flood has been investigated.

The morphodynamics of a swash event on an erodible beach [PDF]
, 2015 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

Influence of Bed‐Load Transport on Flow Resistance of Step‐Pool Channels
Water Resources Research, 2018 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.
