Simulación de Flujos a Superficie Libre con Viento y Marea
Abstract
A cuasi-threedimensional hydrodynamic model for the simulation of flows in which the driving force is determined by combined effects of tide and wind is presented. It is
started from the Navier-Stokes equations and, using the horizontal-velocities vertical profile proposed by de Almeida Rosso-Rosman, the equations are depth-integrated.
Expressions with a bigger number of terms than the known shallow water equations arise. The resolution method of those equations is based in the finite difference one. In order to build the model, the ADI (alternate direction implicit) technique and the structure of HIDROBID I1 computational system, developed at INCYTH, were used.
In this article a justification for the use of a cuasi-threedimensional formulation is presented, the obtention and discretization of the equations are detailed and first results of a validation numerical essays sene are shown.
