Modelagem numérica bidimensional da hidrodinâmica e qualidade da água em reservatório: pré-processador para o modelo CE-QUAL-W2 aplicado ao reservatório Pereira de Miranda

Abstract

Nowadays, Brazilian’s northeast region has reached a new contest where de efforts for water offering maximization from quantitative point of view, by means of damming policies, passes to lose viability unless qualitative warranties are given. This way, it becomes necessary to develop regular monitoring campaigns with capacity to give support to the numerical simulation process of such water bodies. Considering the available alternatives, we can quote CE-QUAL-W2, a vertical-longitudinal two dimension model offered by the United States Army Corps of Engineers (USACE), as the state of the art among hydrodynamics and water quality models. This paper brings up a pre-processing routine, developed based on geoprocessing tools in GIS environment and a MATLAB algorithm, which aims to represent lake’s morphometric characteristics in a consistent way with a numerical model. this procedure reduces the modeler’s effort, making further model’s application in other reservoirs easier.
