Long-term evolution of mid-channel forms in gravel-bed rivers of the Polish Carpathians [PDF]
Scientific ReportsMid-channel forms are key components of fluvial morphology, particularly in gravel-bed rivers where their development reflects sediment transport dynamics, vegetation establishment, and human impacts.

Frequency pattern of turbulent flow and sediment entrainment over ripples using image processing [PDF]
Hydrology and Earth System Sciences, 2012 River channel change and bed scourings are source of major environmental problem for fish and aquatic habitat. The bed form such as ripples and dunes is the result of an interaction between turbulent flow structure and sediment particles at the bed.

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.

Alluvial streams; Bed forms; Reducing width transitions; Ripple height.
مجله آب و خاک, 2017 Introduction: In alluvial streams, water flow affects the sediment and transports them to the downstream constantly. In the meantime, bed forms will be created on stream bed with various dimensions and in different conditions.
