A Mathematical Model for Numerical Simulation of Shallow Water Flow: Description and Practical Application of GUAD|2D

Abstract

GUAD 2D is a finite volume based two-dimensional model for the numerical simulation and analysis of flood waves caused by reasons such as extreme rainfall, gradual or sudden dam break or the release of a big water tank retaining wall. GUAD 2D allows to obtain real results in, critical, subcritical or mixed flow situations over irregular topography. GUAD 2D makes possible different initial conditions, like starting from dry or wet situations, or from the results obtained in a previous simulation.
