Well-balanced finite volume schemes for 2d non-homogeneous hyperboli systems. Application to the dam break of Aznalcóllar. Díaz, Manuel J., C., Chacón-Rebollo, T., Fernández Nieto, E. D., González-Vida, J., & Parés, C. Comput. Methods Appl. Mech. Engrg., 197(45-48):3932–3950, 2008.
Paper abstract bibtex In this paper, we introduce a class of well-balanced finite volume schemes for 2D non-homogeneous hyperbolic systems. We extend the derivation of standard finite volume solvers for homogeneous systems to non-homogeneous ones using the method of lines. We study conservation and some well-balanced properties of the numerical scheme. We apply our solvers to shallow water equations: we prove that these exactly compute the water at rest solutions. We also perform some numerical tests by comparing with 1D solutions, simulating the formation of a hydraulic drop and a hydraulic jump, and studying a real dam break: Aznalcóllar, an ecological disaster that happened in the province of Seville, Spain in 1998
