Time fractional Saint Venant equations reveal the physical basis of hydrograph retardation through model comparison and field data. [PDF]
Sci RepRiver hydrodynamics are influenced by numerous factors that traditional models often fail to fully capture. Simulating complex hydrographs can benefit from parsimonious upscaling models, such as fractional derivative equations, that reduce the need to ...

Accuracy Assessment of Numerical Morphological Models Based on Reduced Saint‐Venant Equations
Water Resources Research, 2023 Sustainable river management often requires long‐term morphological simulations. As the future is unknown, uncertainty needs to be accounted for, which may require probabilistic simulations covering a large parameter domain.

Adaptive finite element methods for solving Saint-Venant equations
Scientia Iranica, 2011 AbstractSolving Saint-Venant equations by the finite element method needs long CPU time (even for a short time). Moreover, if the channel length is fairly large, the system resulted by discretization is not directly solvable, and one should use iterative methods.

KINETIC-INDUCED MOMENT SYSTEMS FOR THE SAINT-VENANT EQUATIONS
TASK 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).

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

FLASH FLOODS SIMULATION USING SAINT VENANT EQUATIONS [PDF]
International Conference on Aerospace Sciences and Aviation Technology, 2007 Flash floods prediction is considered one of the important environmental issues worldwide. In order to predict when and where the flood wave will invade and attack our lives, and provide solutions to deal with this problem it is essential to develop a reliable model that simulates accurately this physical phenomena.

Journal 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,
