A Discrete Boltzmann Model for Transcritical Flows Governed by the Saint‐Venant Equations

Journal of Flood Risk Management
Based on the Hermite expansion approach, a type of discrete Boltzmann model is devised to simulate the open channel flows governed by the Saint‐Venant equations. In this model, a four‐discrete‐velocity set is adopted, and a local equilibrium distribution

Accuracy Assessment of Numerical Morphological Models Based on Reduced Saint‐Venant Equations

Water Resources Research
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.

Finite-volume solvers for a multilayer Saint-Venant system [PDF]

, 2007
We consider the numerical investigation of two hyperbolic shallow water models. We focus on the treatment of the hyperbolic part. We first recall some efficient finite volume solvers for the classical Saint-Venant system.

Optimal flow model for plot irrigation.

Tecnología y ciencias del agua, 2013
The primarily linear relationship was verified between the length of a plot and optimal irrigation flow, which is the flow needed to obtain the maximum value of the uniformity coefficient, resulting in high values for application efficiency and the ...

Numerical methods for hyperbolic equations of Saint-Venant type.

, 2002
The purpose of the dissertation is to contribute to the numerical study of hyperbolic conservation laws with source terms, motivated by the application to the Saint-Venant equations for shallow waters. The first part deals with usual questions in the analysis of numerical approximations for scalar conservation laws.
