Abstract

Ria de Aveiro is a shallow lagoon in the North of Portugal, extremely polluted, mainly as a consequence of the big chemical industries located in its neighbourhood. The purpose of this work is to predict tidal flow fields as well as passive pollutants transport processes in the lagoon, to better understand its normal behaviour and the consequence of the discharges of pollutants in situ. A two-dimensional finite difference numerical model, capable of predicting depth averaged tidal flow fields in estuarine waters has been adapted and extended to this area. The partial differential equations governing the conservation of mass and momentum in an incompressible turbulent flow are included in a dept
