Journal ArticleDOI
A unified bar–bend theory of river meanders
TL;DR: In this paper, a two-dimensional model of flow and bed topography in sinuous channels with erodible boundaries is developed and applied in order to investigate the mechanism of meander initiation.
Journal ArticleDOI
Finite-amplitude alternate bars
TL;DR: In this paper, a predictive theory is proposed to determine the development of finite-amplitude alternate bars in straight channels with erodible bottoms, where an equilibrium amplitude of bedforms is reached as t → ∞ within a wide range of values of the parameter (β − βc)/βc, where t is the time, β is the width ratio of the channel and βc is its critical value below which bars would not form.
Journal ArticleDOI
Long‐term evolution and morphodynamic equilibrium of tidal channels
TL;DR: In this article, the morphodynamic equilibrium of funnel-shaped well-mixed estuaries and/or tidal channels is investigated for the ideal case of a frictionally dominated estuary consisting of noncohesive sediment and with insignificant intertidal storage of water in tidal flats and salt marshes.
Journal Article
Downstream and upstream influence in river meandering. Part 1. General theory and application to overdeepening
Guido Zolezzi,Giovanni Seminara +1 more
TL;DR: In this article, the exact solution of the linearized form of the mathematical problem of river morphodynamics was derived, which applies to channels with constant width and arbitrary curvature distribution.
Journal ArticleDOI
On tide propagation in convergent estuaries
TL;DR: In this article, the problem of one-dimensional tide propagation in convergent estuaries was revisited, and a nonlinear parabolic approximation of the full de Saint Venant equations was developed to describe this behaviour.
