Meandering river dynamics
Meandering channels are dynamic landforms that arise as a result of fluid mechanic and sedimentary processes. Their evolution has been described by the meander morphodynamic equations, which dictate that channel curvature and bed topology give rise to local perturbations in streamwise fluid …

Hydrodynamics and Morphodynamics in Kinoshita Meandering Channels
… hydrodynamics and morphodynamics of transitional meandering channels. Among the hydrodynamic effects, it is observed that downstream skewed configurations produce fully-developed secondary flows around the bend apex, while upstream-skewed configuration results in non-developed secondary flow. The …

Secondary Motion in Meandering Streams: An Experimental Study
Meandering is a common plan shape acquired by rivers. Its prevalence in the environment and highly dynamic nature make the mechanics of flow in meandering streams a great interest for engineers and scientists. Meandering streams are characterized by continuous variation of curvature in the …

Numerical modeling study on meandering and cutoff dynamics
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2024-05-01

Laboratory experiments on alluvial cover in mixed bedrock-alluvial meandering channels and on the formation and evolution of supraglacial meltwater meandering streams
… other channels containing liquid flow develop meandering patterns over different media and across a broad range of scales. For example, alluvial rivers form and evolve by erosion and deposition of sediment, and by interactions with riparian vegetation. Meandering channels also form in bedrock …

Meandering rivers morphodynamics - integrating nonlinear modeling and remote sensing
… investigation of the morphodynamics of meandering rivers mostly involved the theoretical-analytical methodology. The development of analytical models enabled the definition of equilibrium conditions, stability and evolution of river meanders and to investigate the interaction between …

Curvature-Migration Relations and Planform Dynamics of Meandering Rivers
… advancing knowledge of the planform dynamics of meandering rivers. The intellectual merit of the research is the identification of the role of the spatial structure of planform curvature in the dynamics of meander migration. The new knowledge gained from the research provides an improved …

A study of round, line-like and meandering turbulent fountains
The dynamics of different classes of turbulent and miscible fountains are stud- ied: from classic axisymmetric fountains issuing from round sources, to confined fountains propagating in a quasi-two-dimensional environment, to line fountains which form when release conditions are approximately …

The sedimentary architecture of meandering rivers: The influence of bend migration style
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2023-04-12 without embargo terms

Systematic connectivity in single thread meandering alluvial rivers: statistical generalization of hydraulic geometry
… Depth connectivity is investigated in alluvial meandering streams as a solution to river navigability. These types of rivers are naturally ordered systems, which exhibits self-similarity amongst many scales. Four river sections and four experimental runs were used to investigate patterns in …

A nonlinear river meandering model and its incorporation in a landscape evolution model
A topographic steering river meandering (TSRM) model based on continuity of a simplified flow field through bends is developed. The equilibrium coupling between helical flow and sediment transport, as in Ikeda [1989] determines downstream variation of transverse bed slope. The model tests the …

Form and function of anabranches and floodplain secondary channels in lowland meandering river systems
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2026-08-01

Non-cohesive bank migration in meandering rivers and bank accretion in weakly braided rivers
… in the dissertation is the migration of meandering rivers whose banks consist wholly, or partly, of non-cohesive bed-material-sized alluvial deposits; such banks are known as composite banks when the near-surface layers consist of fine-grained deposits. The relevant forces and …

Development of methods to predict the discharge capacity in model and prototype meandering compound channels
… for predicting the discharge capacity of uniform meandering compound channels. The first method utilised an Artificial Neural Network (ANN) functional approximator which was taught to replicate the relationship between 9 of the key parameters and the magnitude of F* which was exhibited by the flow …

The influence of channel-skewed bedforms on flow structure in a high-amplitude meandering channel
… flow structure in a high-amplitude experimental meandering channel under differing substrate conditions. Three separate substrate morphologies were tested in the Kinoshita experimental meandering channel at the Ven Te Chow Hydrosystems Laboratory. The first consisted of a flatbed condition with …
