Abstract

Finite element techniques for water quality models F.L.B.Ribeiro*, A.C. Galeao^, N.M.L. Romeiro*, L. Landau^ ^ Universidade Federal do Rio de Janeiro - UFRJ, Programa de Engenharia Civil, COPPE, Rio de Janeiro, Brazil ^Laboratorio Nacional de Computa^do Cientifica - LNCCIMCT, Petropolis, Brazil Abstract In this paper a stabilized finite element water quality model for coastal estuaries and bays is presented. The systems of equations arising from the finite element discretization are solved using predictor multi-corrector algorithms. The derived formulation, considering water quality parameters such as biochemical oxygen demand and dissolved is applied to a case of practical interest: the coastal lagoon of Araruama, situated in the State of Rio de Janeiro, Brazil. 1 Introduction Water Quality Models are primarily concerned with the observed concentration of the biochemical oxygen demand (BOD) and its related concentration of dissolved oxygen (DO). Immersed in fluid medium those
