Modeling of river pollution contributes to better management of water quality and this will
lead to the improvement of human health. The advection dispersion equation (ADE) is the …

In this work, we present a new analytical model for the prediction of pollutant dispersion in
the atmospheric boundary layer incorporating either the spatial and temporal continuous …

In this work we present the solution of the two-dimensional advection-diffusion equation by
the GILTT method. The GILTT approach uses, in the series expansion, eigenfunctions given …

In this study an integral and an algebraic formulation for the eddy diffusivities in a shear
driven planetary boundary layer are derived for pollutant dispersion applications. The …

Abstract Large Eddy Simulation (LES) spectral data and Taylor statistical diffusion theory are
used to obtain Eddy diffusivities in a convective boundary layer. The derivation employs a …

Atmospheric air pollution turbulent fluxes can be assumed proportional to the mean
concentration gradient. This assumption, along with the equation of continuity, leads to the …

The present discussion focuses on the dispersion of pollution plumes in the atmospheric
boundary layer. From a comparison between first order perturbation theory with equivalent …

The work in this chapter is a contribution to a larger program, whose objective is to
determine general closed form solutions and allows us to match a variety of meteorological …

Episódios envolvendo despejos de resıduos lıquidos e degradaçao dos corpos hıdricos
vem sendo recorrentes ao longo da história. Tendo em vista a preservaç ao dos recursos …

Esta tese tem o objetivo de apresentar um modelo matemático, para simular a dispersão de
poluentes na atmosfera, que considera a variação temporal do campo de vento e dos …
