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.

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 ...

A Saint-Venant Model for Overland Flows with Precipitation and Recharge

Mathematical and Computational Applications, 2020
We propose a one-dimensional Saint-Venant (open-channel) model for overland flows, including a water input–output source term modeling recharge via rainfall and infiltration (or exfiltration).

Efficient analytical implementation of the DOT Riemann solver for the de Saint Venant–Exner morphodynamic model [PDF]

, 2018
Within the framework of the de Saint Venant equations coupled with the Exner equation for morphodynamic evolution, this work presents a new efficient implementation of the Dumbser-Osher-Toro (DOT) scheme for non-conservative problems.

Emulation of the Saint Venant Equations Enables Rapid and Accurate Predictions of Infiltration and Overland Flow Velocity on Spatially Heterogeneous Surfaces

Water Resources Research, 2019
The interleaving of impermeable and permeable surfaces along a runoff flow path controls the hillslope hydrograph, the spatial pattern of infiltration, and the distribution of flow velocities in landscapes dominated by overland flow.

On state-space elastostatics within a plane stress sectorial domain: the wedge and the curved beam

, 2008
The plane stress sectorial domain is analysed according to a state-space formulation of the linear theory of elasticity. When loading is applied to the straight radial edges (flanks), with the circular arcs free of traction, one has the curved beam; when
