Title in Portuguese
Dispersão de efluentes no oceano.
Keywords in Portuguese
Efluentes (Dispersão)
Oceanos
Abstract in Portuguese
A permanente contaminacao das aguas litoraneas por residuos domesticos e industriais, exigem um melhor conhecimento dos fenomenos de dispersao no mar e dos sistemas de lancamento dos efluentes em seu seio. A orientacao deste trabalho e a de fornecer subsidios ao conhecimento e equacionamento dos fenomenos de transporte de massa ou de poluentes no mar. Os fenomenos de dispersao no mar apresentam duas formas basicas chamadas: a) misturacao ou dispersao horizontal, com caracteristicas naturais. B) diluicao inicial, com caracteristicas forcadas por tecnicas que aproveitam as diferencas de massa especifica e momentum. No desenvolvimento deste trabalho sao mostradas as caracteristicas da dispersao, seus conceitos basicos e os fatores que intervem. Sao mostradas as caracteristicas e conceitos basicos dos modelos fisicos de diluicao inicial e dos modelos de misturacao, incluindo analise e discussao dos diferentes casos. E mostrada a importancia da diluicao inicial em relacao a misturacao e se indicam os casos tipicos de diluicao inicial, incluindo a modelagem matematica e o desenvolvimento da analise dimensional.

Abstract in English
The permanent contamination of the litoral water by domestic and industrial residue claims a better knowledge of the ocean sewage dispersion and the ocean waste disposal system. This work is oriented to provide subsidy for the knowledge of the ocean mass transport phenomena and pollution. The ocean dispersion phenomena present two basic forms: a) the horizontal mixing or horizontal dispersion with the natural characteristics. B) the initial dilution with the forced characteristics for the density difference and momentum techniques. In the development of this work is shown the dispersion characteristics, its basic concept and the intervenient factors. The basic concept and characteristics of the initial dilution and the horizontal dispersion physical models, with analysis and discussion for the different case are presented. The initial dilution significance with regard to the horizontal dispersion and the initial dilution typical case with the mathematical models and the development of the dimensional analysis are included.
