Heterogeneous Parallel Implementation of Large-Scale Numerical Simulation of Saint-Venant Equations

open access: yesApplied Sciences, 2022
Large-scale floods are one of the major events that impact the national economy and people’s livelihood every year during the flood season. Predicting the factors of flood evolution is a worldwide problem.

A lattice Boltzmann model for the open channel flows described by the Saint-Venant equations [PDF]

open access: yesRoyal Society Open Science, 2019
A new lattice Boltzmann method to simulate open channel flows with complex geometry described by a conservative form of Saint-Venant equations is developed.

Multilayer Saint-Venant equations over movable beds

open access: yesDiscrete and Continuous Dynamical Systems - Series B, 2011
We introduce a multilayer model to solve three-dimensional sediment transport by wind-driven shallow water flows. The proposed multilayer model avoids the expensive Navier-Stokes equations and captures stratified horizontal flow velocities. Forcing terms are included in the system to model momentum exchanges between the considered layers.

A new form of the Saint-Venant equations for variable topography [PDF]

open access: yesHydrology and Earth System Sciences, 2020
The solution stability of river models using the one-dimensional (1D) Saint-Venant equations can be easily undermined when source terms in the discrete equations do not satisfy the Lipschitz smoothness condition for partial differential equations ...

Numerical Simulation of Propagation and Run-Up of Long Waves in U-Shaped Bays

open access: yesFluids, 2021
Wave propagation and run-up in U-shaped channel bays are studied here in the framework of the quasi-1D Saint-Venant equations. Our approach is numerical, using the momentum conserving staggered-grid (MCS) scheme, as a consistent approximation of the ...

A shock-capturing meshless method for solving the one-dimensional Saint-Venant equations on a highly variable topography

open access: yesJournal of Hydroinformatics, 2023
The Saint-Venant equations are numerically solved to simulate free surface flows in one dimension. A Riemann solver is needed to compute the numerical flux for capturing shocks and flow discontinuities occurring in flow situations such as hydraulic jump,

SAINT VENANT COMPATIBILITY EQUATIONS IN CURVILINEAR COORDINATES [PDF]

open access: yesAnalysis and Applications, 2007
We first establish that the linearized strains in curvilinear coordinates associated with a given displacement field necessarily satisfy compatibility conditions that constitute the "Saint Venant equations in curvilinear coordinates". We then show that these equations are also sufficient, in the following sense: If a symmetric matrix field defined ...

KINETIC-INDUCED MOMENT SYSTEMS FOR THE SAINT-VENANT EQUATIONS

open access: yesTASK Quarterly, 2013
Based on the relation between kinetic Boltzmann-like transport equations and nonlinear hyperbolic conservation laws, we derive kinetic-induced moment systems for the spatially one-dimensional shallow water equations (the Saint-Venant equations).

Existence of Global Classical Solutions for the Saint-Venant Equations

open access: yesВладикавказский математический журнал, 2022
Nowadays, investigations of the existence of global classical solutions for non linear evolution equations is a topic of active mathematical research. In this article, we are concerned with a classical system of shallow water equations which describes long surface waves in a fluid of variable depth.
