Abstract
Human activity often generates effluents that pollute waterways and tend
to generate serious environmental problems. A very useful tool to help
assess these issues is the mathematical modeling. A specific class of
models that are very promising for water resources and pollution control
are the agent-based models. This paper presents an agent-based model
developed and used to simulate plumes of conservatives and
non-conservatives constituents in water courses. The assumptions made
for the representation of advection, dispersion and first order decay
phenomena's on the development of the model are presented, and these
solutions are evaluated against the analytical solution of
one-dimensional advection-dispersion equation. The results of the
comparisons show a good representation of the agent-based model, and
show the importance of the released constituent's mass discretization
definition. The solutions developed and presented are promising for the
application of agent based models in the simulation of impacts of
discharges into watercourses, as well as the developed model presents
itself as an educational tool for simple understanding of the simulated
phenomena.
