Minimizing computational cost is one of the major challenges in the modeling and numerical analysis of hydrodynamics, and one of the ways to achieve this is by the use of quadtree grids. In this article, we present an adaptive scheme on quadtree grids for variable density shallow water equations. A scheme for the coupled system is developed based on the work of [M.A. Ghazizadeh, A. Mohammadian, and A. Kurganov, Computers & Fluids, 208 (2020)]. The scheme is capable of exactly preserving “lake… 
Adaptive Central-Upwind Scheme on Triangular Grids for the Shallow Water Model with variable density
In this paper, we construct a robust adaptive central-upwind scheme on unstructured triangular grids for two-dimensional shallow water equations with variable density. The method is wellbalanced,


Balanced Central Schemes for the Shallow Water Equations on Unstructured Grids
A two-dimensional, well-balanced, central-upwind scheme for approximating solutions of the shallow water equations in the presence of a stationary bottom topography on triangular meshes and notes in passing that it is straightforward to extend the KP scheme to general unstructured conformal meshes.
Central-upwind schemes for the system of shallow water equations with horizontal temperature gradients
A central-upwind scheme for one- and two-dimensional systems of shallow-water equations with horizontal temperature gradients (the Ripa system) is introduced, which is highly accurate, preserves two types of “lake at rest” steady states, and is oscillation free across the temperature jumps.
Adaptive Q-tree Godunov-type scheme for shallow water equations
SUMMARY This paper presents details of a second-order accurate, Godunov-type numerical model of the twodimensional shallow water equations (SWEs) written in matrix form and discretized using finite
Finite-volume schemes for shallow-water equations
This paper focuses on central-upwind schemes, which belong to the family of Godunov-type Riemann-problem-solver-free central schemes, but incorporate some upwinding information about the local speeds of propagation, which helps to reduce an excessive amount of numerical diffusion typically present in classical (staggered) non-oscillatory central schemes.
