title = "Solution of two-dimensional shallow water equations by a localized radial basis function collocation method",

abstract = "A localized version of the Radial Basis Function (RBF) collocation method, is employed for solving the two-dimensional ShallowWater Equations (SWEs). The Newton-Raphson method is used to solve the resulting system of non-linear algebraic equations and a first-order implicit scheme is implemented for temporal discretisation. In order to obtain non-smooth functions which describe height and velocity at supercritical regimes, RBFs are used to approximate dependent variable products instead variable values by means of a local formulation in generalized finite difference fashion. Accurate solutions are obtained for sub-and trans-critical regimes in one-dimensional problems whose analytical solution are reported elsewhere. For verifying two-dimensional spatial and temporal discretization, an oscillatory problem with analytical solution are solved to show the capability of the method for accurately solve 2-D problems. In general, excellent results are achieved regarding the fact that no upwinding scheme are employed when solving transcritical regime problems.",
