On Saint Venant - Kirchhoff imperfect interfaces [PDF]

open access: yesInternational Journal of Non-Linear Mechanics, 2017
Using matched asymptotic expansions with fractional exponents, we obtain original transmission conditions describing the limit behavior for soft, hard and rigid thin interphases obeying the Saint Venant-Kirchhoff material model. The novel transmission conditions, generalizing the classical linear imperfect interface model, are discussed and compared ...

Consistent initial conditions for the Saint-Venant equations in river network modeling [PDF]

open access: yesHydrology and Earth System Sciences, 2017
Initial conditions for flows and depths (cross-sectional areas) throughout a river network are required for any time-marching (unsteady) solution of the one-dimensional (1-D) hydrodynamic Saint-Venant equations.

Numerical study of the applicability of the Saint-Venant principle

open access: yesMATEC Web of Conferences, 2017
The limits of the applicability of the Saint-Venant principle are investigated while using the LIRA-CAD app. A large number of bars loaded at the end with different loads are considered.

Physics‐Informed Neural Networks of the Saint‐Venant Equations for Downscaling a Large‐Scale River Model [PDF]

open access: yesWater Resources Research, 2022
Large‐scale river models are being refined over coastal regions to improve the scientific understanding of coastal processes, hazards and responses to climate change.

PI controllers for the general Saint-Venant equations [PDF]

open access: yesJournal de l'École polytechnique. Mathématiques, 2021
We study the exponential stability in the $H^{2}$ norm of the nonlinear Saint-Venant (or shallow water) equations with arbitrary friction and slope using a single Proportional-Integral (PI) control at one end of the channel.

A splitting scheme for the coupled Saint-Venant-Exner model [PDF]

open access: yesAdvances in Water Resources, 2021
We present a splitting method for the one-dimensional Saint-Venant-Exner equations used for describing the bed evolution in shallow water systems. We adapt the flux vector splitting approach of Toro and Vazquez-Cend\`on and identify one subsystem of ...

A Multilayer Saint-Venant Model

open access: yes, 2004
We introduce a new variant of the multilayer Saint-Venant system. The classical Saint-Venant system is a well-known approximation of the incompressible Navier-Stokes equations for shallow water flows with free moving boundary. Its efficiency, robustness and low computational cost make it very commonly used.

Development of an algorithm for calculating stable solutions of the Saint-Venant equation using an upwind implicit difference scheme

open access: yesEastern-European Journal of Enterprise Technologies, 2021
The problem of numerical determination of Lyapunov-stable (exponential stability) solutions of the Saint-Venant equations system has remained open until now.

Numerical Simulation of Flood Routing using the Simplified Saint Venant Equations in Rectangular Channels

open access: yesInPrime, 2021
Floods, which cause a lot of damage, are a natural phenomenon that often occurs during the rainy season. Flood occurs because the discharge entering the channel exceeds the channel capacity.

Torsion of Functionally Graded Anisotropic Linearly Elastic Circular Cylinder

open access: yesEngineering Transactions, 2018
The object of this paper is Saint-Venant torsion of functionally graded anisotropic linearly elastic circular cylinder. The class of anisotropy considered has at least one plane of elastic symmetry normal to the axis of the circular cylinder. The elastic
