Asymptotic Stability of Steady-states for Saint-Venant Equations with Real Viscosity

2007
We deal with the viscous Saint-Venant model and analyze the stability of stationary steady states. We skip all of the technical details of the analysis, stressing only the kind of result we are able to prove at the present and the main lines of the proof.

Solution of the inverse problem for the Saint Venant equations

Journal of Hydrology, 1993
Abstract This paper presents the formulation of the inverse problem for the Saint Venant equations. It appears that this problem can be posed only for subcritical channel flow. The equations of unsteady flow are integrated in the domain 0 ≤ t ≤ T and x ≤ 0 and solved using an implicit four-point difference scheme.

Numerical Integration of the System of Saint Venant Equations

2009
This chapter begins with brief review of the numerical methods applicable for the Saint Venant equations. Detailed description of the finite difference Preissmann scheme and of the modified finite element method used for a channel with fixed bed is provided.

Limitations of de Saint Venant Equations in Dam‐Break Analysis

Journal of Hydraulic Engineering, 1989
Results of solitary waves and laboratory-scale, dam-breach flood waves propagating in one-dimensional channels are compared as described by finite difference analog equations to the de Saint Venant and Boussinesq equation systems. Additional terms accounting for streamline curvature effects on the vertical pressure distribution extend the long-wave ...
