CONSTAIN ARAGON, ALFREDO JOSÉ. DEFINITION AND ANALYSIS OF AN EVOLUTION FUNCTION OF DISPERSIVE SOLUTES IN NATURAL FLOWS. Dyna rev.fac.nac.minas [online]. 2012, vol.79, n.175, pp.173-181. ISSN 0012-7353.

Given the acute and increasing problems of decline of water in the industrialized modern world it is indispensable to gather together a deep knowledge of those dispersion mechanisms of solutes in natural flows that allows predict and control those variables associated with hydric contaminations. In this article it is stated the definition of a special function that drives the energetic evolution of this phenomenon and then it has a wide application in present water quality. This function has the advantage to be an easy mathematical expression, with great generality and also to be interpretate with a very intuitive reasoning. It is presented a practical application of these concepts to a small mountain stream accomplishing satisfactory the required experimental validation, to earlier stages of tracer plume formation.

Keywords : Dispersion; Gaussian dynamics; water quality studies.
