River meandering dynamics [PDF]
Physical Review E, 2002 The Ikeda, Parker, and Sawai river meandering model is reexamined using a physical approach employing an explicit equation of motion. For periodic river shapes as seen from above, a cross-stream surface elevation gradient creates a velocity shear that is responsible for the decay of small-wavelength meander bends, whereas secondary currents in the ...

Critical wavelength for river meandering [PDF]
Physical Review E, 2001 A fully nonlinear modal analysis identifies a critical centerline wave number q(c) for river meandering that separates long-wavelength bends, which grow to cutoff, from short-wavelength bends, which decay. Exact, numerical, and approximate analytical results for q(c) rely on the Ikeda, Parker, and Sawai [J. Fluid Mech.

The influences of lateral ground-tilting on channel morphology and alluvial architecture [PDF]
, 1995 This thesis characterises and quantifies the influence of lateral ground-tilting on rivers in terms of: i) channel planform changes and migration style, ii) temporal and spatial patterns of channel movement, and, iii) the preserved alluvial architecture

Water Policy, 2022 In the present study, the meandering behavior of the Barak River (Cachar), Assam was traced. Flow path length, meander neck length, sinuosity index, and river migration were determined segment-by-segment to demonstrate morphological changes. Decadal land-

Development of a meandering channel caused by the planform shape of the river bank [PDF]
Earth Surface Dynamics, 2014 Due to a typhoon and a stationary rain front, record amounts of rain fell in September 2011, and the largest class of discharge in recorded history was observed in the Otofuke River of eastern Hokkaido in Japan, and extensive bank erosion occurred in ...

ZAB RIVER (IRAQ) SINUOSITY AND MEANDERING ANALYSIS BASED ON THE REMOTE SENSING DATA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 This work studies the meandering and change of paths along the Zab River in Iraq. Landsat-5 TM, Landsat-7 ETM+ and Landsat-8 (2-sets) images were acquired from the years 1989, 1999, 2015 and 2019, respectively, which were used together with Remote ...

Spatiotemporal morphological change and lateral migration of high-sinuosity bends in the Black River
Shui kexue jinzhan, 2023 The Source Region of the Yellow River is widely developed with meandering rivers of different channel width scales, which are characterized by high sinuosity, complex morphology, and dynamic migration.The spatiotemporal variations in morphological ...

Authoring and Simulating Meandering Rivers
ACM Transactions on Graphics, 2023 We present a method for interactively authoring and simulating meandering river networks. Starting from a terrain with an initial low-resolution network encoded as a directed graph, we simulate the evolution of the path of the different river channels using a physically-based migration equation augmented with control terms. The curvature-based terms in
