Abstract

In the present Project, the environmental impact will be evaluated through the interpretation, observation and graphic representation of part of the earth’s surface, considering as experimental territorial unit the hydrographic microbasin, and the analysis of the environment, with regard to the data collected on the physical-chemical parameters of the hydric resources, sediment and soil, in accordance with the alterations deriving from human activities, using in juxtaposition the analysis of data and maps elaborated in the Geographical Information System (GIS). Thus, we will evaluate hydrographic microbasins of the first order of magnitudewith sources protected by forest, by reforestation in the initial stage and with a preponderance of agricultural activities. The hydrographic microbasin to be studied will be that of the Córrego da Fazenda da Glória, located in the municipality of Taquaritinga (SP). The use/occupation of the soil and the topographywill be evaluated and all the information collected will be used in support of environmental planning. (AU)
