Riemann Solver for 2D Shallow Water Equations Using Finite Volume Method with HLL Scheme for Boundary Numerical Fluxes

A MATLAB-implemented Riemann solver employing the Finite Volume Method with HLL scheme to compute boundary numerical fluxes for 2D shallow water equations. Handles dry bed problems effectively and works with both structured and unstructured grids. Requires only water depth, flow velocity, and outward normal vectors as input parameters, with built-in flux computation algorithms for robust hydraulic simulations.
