Modelos matemáticos para dispersão de poluentes: aplicação ao estudo da bacia hidrográfica subterrânea do aquífero Boa Viagem.

Abstract

The increasing uncontrolled groundwater exploitation has been the source of many contamination and subsequent degradation problems of such systems. Techniques that allow an effective and accurate prediction of the effects over time arising from the introduction of pollutants at certain points of a system are essential for developing public policies for them sustainable exploitation, as well as for developing remediation methods and recovery of degraded areas. Therefore, the objective of this dissertation is to create a streamlined system for managing underground water, allowing the zoning of the capture points from Boa Viagem underground area, find out the geographical and temporal evolution of possible indoor pollutants. In the temporal evolution of the dispersion, degradation or accumulation of pollutants, allowing the manager of water resources to create scenarios for the prevention or recovery from degradation. The mathematical model proposed here will be applied to contribute to the knowledge of pollutants dispersion that may contaminate the Boa Viagem aquifer in this basin in Recife and the metropolitan area.
