Resumo
This research approaches the soil usage and occupation process and the changes occurred due
to different usages of water quality and ciliary environments present in the Ribeirão
Samambaia watershed area in Catalão (GO).The analysis of the indicators or variables aims to
evaluate and show the main usages that have caused the reduction of water quality and the
need of political applications that envisions its conservation. The recovery of ciliary
environment is also part of this investigation, since its maintenance contributes to the increase
of environmental quality. The study methodology used was the indicators of soil usage, such
as urbanization, agriculture, pasturage and vegetal coverage, holding as reference the Mata de
Galeria and the consequential analysis of water quality, based on the Environmental National
Counsel Resolution (Resolução do Conselho Nacional do Meio Ambiente – CONAMA) nº.
357/2005. All of those indicators were compared to the water analysis, evaluating the
influence of each usage in its quality and landscaping dynamics. The results found in the three
series of analysis comprising the year 2011 have made possible the comprehension of the soil
usage planning importance in order to preserve the ciliary environment and the water quality,
highlighting the need of a recovering work and maintenance of water quality, mainly in the
catchment patch and the Ribeirão’s affluents, where significant results for the presence of
Total Coliforms and Thermotolerant were found, which demands corrective and source
control contamination actions. In the ciliary environment is observed the necessity of a review
in the recovery program which presents factors that have compromised the Matas de Galeria
restoration. The Ribeirão Samambaia watershed, responsible for the public supply of Catalão
city, needs actions that aim the planning through the implantation of projects to prevent and
manage the occupation and usages given to its area, since the water quality can be
compromised by these processes. The articulation between management politics of those
environments as well as the framework of the surrounding areas near the catchment patch and
the creation of a plan that integrates these actions is necessary to guarantee the multiple
usages of water, as well as avoiding future conflicts by demand and availability of water in
the spring.
