Journal ArticleDOI
Hierarchy of models for meandering rivers and related morphodynamic processes
TL;DR: In this paper, the importance of the physical mechanisms involved in river meandering by comparing some existing linear models and extensions thereof is discussed with a detailed discussion of physical processes and relevant hypotheses that are involved.
Journal ArticleDOI
On the long-term behavior of meandering rivers
TL;DR: In this paper, the authors show that the long-term equilibrium conditions are essentially governed by only one spatial scale and one temporal scale (proportional to the ratio of the river depth and the friction coefficient) that contain the most important fluid dynamic quantities.
Journal ArticleDOI
Mechanisms of vegetation uprooting by flow in alluvial non-cohesive sediment
TL;DR: In this article, the authors proposed two modelling mechanisms (Type I and Type II) for root development in early germinated and mature vegetation, respectively concerning the uprooting time scales.
Journal ArticleDOI
Viscoplastic dam breaks and the Bostwick consistometer
TL;DR: In this article, the authors present a theoretical and experimental analysis of the dam break of a viscoplastic fluid in a horizontal channel, using a shallow, slow fluid model based on the Herschel-Bulkley constitutive law to characterize the early and late stages of flow, the final state and the dependence on yield stress and nonlinear viscosity.
