Este articulo trata sobre las ventajas de utilizar 2 modelos de dispersión "nube" y "partículas", en breve, el centro de masa de cada
nube se mueve a través de una "trayectoria de partícula". Palabras clave: Modelado de dispersión, puff models, modelos de
partículas, dispersión relativa.

AFTOX 4.0 - The Air Force Toxic Chemical Dispersion Model
AFTOX was developed for real time analysis of non-buoyant, toxic chemical releases. Use of AFTOX is governed by AFR 355-1. AFTOX
is written so that Air Weather Service (AWS) base weather stations can apply AFTOX to continuous or instantaneous, gas or liquid
releases from either ground or elevated sources. It can also be applied to heated plumes from smokestacks. AFTOX contains 130
chemicals on file and is able to accept additional chemicals.

DEGADIS 2.1 - Dense Gas Dispersion Model
The DEGADIS model was originally developed for the U.S. Coast Guard and the Gas Research Institute primarily for simulation of the
dispersion of cryogenic flammable gases. Subsequent work sponsored by the U.S. Environmental Protection Agency extended
DEGADIS for simulation of the dispersion of vertical jets. Implementation of DEGADIS on a personal computer was sponsored by the
Gas Research Institute and the American Petroleum Institute.

PESTAN 4.0 - Pesticide Analytical Model
The PESTAN (Pesticide Analytical) model is a computer code for estimating the transport of organic solutes through soil to
groundwater. The model is based on a closed-form analytical solution of the advective-dispersive-reactive transport equation. The
model was developed by Enfield, et al. in 1982 and has since been used by the EPA Office of Pesticides Program (OPP) for initial
screening assessments to evaluate the potential for groundwater contamination of currently registered pesticides and those submitted
for registration (Donigian and Rao 1986). The model has also been tested under field and laboratory conditions (Enfield et al., 1982;
Jones and Back, 1984; Melancon et al., 1986). Although the model is based on a simple analytical solution, it may be useful in making
preliminary assessments as long as the user is fully aware of its assumptions and limitations. Therefore, it is the principal objective of
this User's Guide to provide essential information on the aspects such as model conceptualization, model theory, assumptions and
limitations, determination of input parameters, analysis of results and sensitivity analysis (parameter studies). With the information
presented, it is hoped that this manual will help the user in making the best possible use of the model.
