Numerical Simulation of Flood Routing using the Simplified Saint Venant Equations in Rectangular Channels

InPrime, 2021
Floods, which cause a lot of damage, are a natural phenomenon that often occurs during the rainy season. Flood occurs because the discharge entering the channel exceeds the channel capacity. If the discharge data in the upstream area that will enter the

Correspondence between de Saint-Venant and Boussinesq 2: Boussinesq’s professional and private life up to 1886

Comptes Rendus. Mécanique, 2020
Joseph Boussinesq is among the great physicists of the late 19th and the early 20th centuries, mainly due to his novel techniques to mathematically solve complicated equations by an adopted method of approximations.

Comparison and Optimization of Sparse Matrix Solution Methods in One-dimensional Saint-Venant Equation Difference Numerical Algorithm

Guan'gai paishui xuebao, 2021
【Background】 In order to alleviate the shortage of water resources, China has established many water transfer projects. Due to its long water transfer distance, large water delivery volume, and numerous water passing buildings along the line, the control

Analytic Normalized Solutions of 2D Fractional Saint-Venant Equations of a Complex Variable

Journal of Function Spaces, 2021
Saint-Venant equations describe the flow below a pressure surface in a fluid. We aim to generalize this class of equations using fractional calculus of a complex variable.

On Saint Venant - Kirchhoff imperfect interfaces [PDF]

International Journal of Non-Linear Mechanics, 2017
Using matched asymptotic expansions with fractional exponents, we obtain original transmission conditions describing the limit behavior for soft, hard and rigid thin interphases obeying the Saint Venant-Kirchhoff material model. The novel transmission conditions, generalizing the classical linear imperfect interface model, are discussed and compared ...

Modeling of Unsteady Flow through the Canals by Semiexact Method

Modelling and Simulation in Engineering, 2014
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 ...

Consistent initial conditions for the Saint-Venant equations in river network modeling [PDF]

Hydrology and Earth System Sciences, 2017
Initial conditions for flows and depths (cross-sectional areas) throughout a river network are required for any time-marching (unsteady) solution of the one-dimensional (1-D) hydrodynamic Saint-Venant equations.

Numerical study of the applicability of the Saint-Venant principle

MATEC Web of Conferences, 2017
The limits of the applicability of the Saint-Venant principle are investigated while using the LIRA-CAD app. A large number of bars loaded at the end with different loads are considered.
