Three-layer approximation of two-layer shallow water equations

open access: yesMathematical Modelling and Analysis, 2013
Two-layer shallow water equations describe flows that consist of two layers of inviscid fluid of different (constant) densities flowing over bottom topography.

The effect of water stage on the infiltration rate for initially dry channels [PDF]

open access: yes, 2007
Several hydrological models that are used for simulating the water flow in rivers and channels are based on the shallow water equations as in Copeland and El-Hanafy, (2006) or Saint Venant equations (El-Hanafy and Copeland, 2007a). Both the shallow water

A brief overview of modern research of the processes dynamics in unsteady water ows using the shallow water equation

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2021
In hydrodynamics (hydraulics), there are numerous approaches to solving the problem of water flow dynamics control in river beds and channels, while the results of each methods differ, and estimates of their reliability do not always exist.

Traveling wave solutions for shallow water equations

open access: yesJournal of Ocean Engineering and Science, 2017
An extended homogeneous balance method is suggested in this paper. Based on computerized symbolic computation and the homogeneous balance method, new exact traveling wave solutions of nonlinear partial differential equations (PDEs) are presented.

Numerical Simulation of Nonlinear Wave Propagation from Deep to Shallow Water

open access: yesJournal of Marine Science and Engineering, 2023
Herein, a numerical model is proposed to simulate the nonlinear wave propagation from deep to shallow water and wave breaking phenomena. In the numerical model, the governing equations selected, in which the momentum equations were added to the eddy ...

A mixed discontinuous/continuous finite element pair for shallow-water ocean modelling [PDF]

open access: yes, 2008
18.02.14 KB. Ok to add accepted version to spiral, Elsevier says ok while mandate not enforced.We introduce a mixed discontinuous/continuous finite element pair for ocean modelling, with continuous quadratic layer thickness and discontinuous velocity. We

Balance, gravity waves and jets in turbulent shallow water flows [PDF]

open access: yes, 2009
This thesis contains a thorough investigation of the properties of freely decaying turbulence in a rotating shallow water layer on a sphere. A large number of simulations, covering an extensive range of Froude and Rossby numbers, have been carried out ...

Relative entropy for compressible Navier-Stokes equations with density dependent viscosities and various applications

open access: yesESAIM: Proceedings and Surveys, 2017
This paper provides the full proof of the results announced by the authors in [C. R. Acad. Sciences (2016)]. We introduce an original relative entropy for compressible Navier-Stokes equations with density dependent viscosities and discuss some possible ...

One-Dimensional Shallow Water Equations Ill-Posedness

open access: yesMathematics
In 2071, the Hydraulic community will commemorate the second centenary of the Baré de Saint-Venant equations, also known as the Shallow Water Equations (SWE). These equations are fundamental to the study of open-channel flow.

Integrable Shallow‐Water Equations and Undular Bores [PDF]

open access: yesStudies in Applied Mathematics, 2001
On the basis of the integrable Kaup–Boussinesq version of the shallow‐water equations, an analytical theory of undular bores is constructed. A complete classification for the problem of the decay of an initial discontinuity is made.
