Hydrostatic Upwind Schemes for Shallow–Water Equations
نویسندگان
چکیده
We consider the numerical approximation of the shallow–water equations with non–flat topography. We introduce a new topography discretization that makes all schemes to be well–balanced and robust. At the discrepancy with the well–known hydrostatic reconstruction, the proposed numerical procedure does not involve any cut–off. Moreover, the obtained scheme is able to deal with dry areas. Several numerical benchmarks are performed to assert the interest of the method.

Efficient well-balanced hydrostatic upwind schemes for shallow-water equations
The proposed work concerns the numerical approximations of the shallow-water equations with varying topography. The main objective is to introduce an easy and systematic technique to enforce the well-balance property and to make the scheme able to deal with dry areas. To access such an issue, the derived numerical method is obtained by involving the free surface instead of the water height and ...
متن کاملDepth-integrated, non-hydrostatic model for wave breaking and run-up
This paper describes the formulation, verification, and validation of a depth-integrated, non-hydrostatic model with a semi-implicit, finite difference scheme. The formulation builds on the nonlinear shallow-water equations and utilizes a non-hydrostatic pressure term to describe weakly dispersive waves. A momentumconserved advection scheme enables modeling of breaking waves without the aid of ...
متن کاملSpace-time Least-squares Finite-element Method for Shallow-water Equations
In this paper, a space-time least-squares finite-element method for the 2D nonlinear shallow-water equations (SWE) is developed. The method can easily handle complex geometry, bed slope (source term), and radiation boundary condition without any special treatment. Other advantages of the method include: high order approximations in space and time can easily be employed, no upwind scheme is need...
متن کاملCentral-Upwind Scheme for Shallow Water Equations with Discontinuous Bottom Topography
Finite-volume central-upwind schemes for shallow water equations were proposed in [A. Kurganov and G. Petrova, Commun. Math. Sci., 5 (2007), 133–160]. These schemes are capable of maintaining “lake-at-rest” steady states and preserving the positivity of the computed water depth. The well-balanced and positivity preserving features of the central-upwind schemes are achieved, in particular, by us...
متن کاملAIAA 2001–2623 Multi-Dimensional Upwind Constrained Transport on Unstructured Grids for ‘Shallow Water’ Magnetohydrodynamics
Novel Multi-dimensional Upwind Constrained Transport (MUCT) schemes on un-structured triangular grids are described. Constrained Transport (CT) discretizations conserve the divergence-free nature of divergence-free vector fields on the discrete level. Multi-dimensional Upwind (MU) schemes generalize the concept of dimensionally split upwind schemes for hyperbolic systems to truly multidimension...
