abstract = "The eutrophication process in aquatic systems may be caused by
point and non -point pollution sources. The latter is hard to be
quantified and determined.I this framework,new methods using the
advances in geotechnologies can represent a powerful tool to
improve the estimates of non-point sources.This paper proposes the
integration of watershed physical variables using the GIS
technology as a tool to improve non -poi t load estimates into
aquatic ecosystems. Barra Bonita reservoir watershed was selected
as test site.The georreferenced database includes the following
layers:drainage density,sub basin limits,distance from sub basins
to the reservoir and rainfall distribution.Based uponthose
variables the potential non-point pollution for each basin are
computed using a multi-criteria decision technique.In the next
step of the research,these data will be integrated to a model that
estimates the potential pollutant export rates taking into account
the various degrees of human interference in the reservoir
drainage basin.",
