PI controllers for the general Saint-Venant equations
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 ...

Numerical modeling of the flood routing and zoning by Saint-Venant in the river Bostanak [PDF]
The equations governing transient open-channel flow are continuity and momentum equations that are known as Saint-Venant equation. Based on the simplifications of this equation, numerical models of flood routing are categorized.

Modeling of Unsteady Flow through the Canals by Semiexact Method
The study of free-surface and pressurized water flows in channels has many interesting application, one of the most important being the modeling of the phenomena in the area of natural water systems (rivers, estuaries) as well as in that of man-made ...

Coupling Green-Ampt and Saint-Venant Equations for Estimating of Transmission Losses during Flood Routing in Rivers [PDF]
Volume of flooding flow volume in ephemeral streams decreases due to evaporation as well as the channel wall and bed penetration. This process is known as transmission losses.

Multilayer Saint-Venant equations over movable beds
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 Multilayer Saint-Venant Model [PDF]
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.
