ABSTRACT
The municipality of Guarulhos, second large in population, state of São Paulo belongs to the RMSP -- Metropolitan Region of São Paulo, has suffered from a disorderly and accelerated occupation during the decades. Fisiogeographically divided in two macro compartments, separated by Jaguari River Fault, Guarulhos has in its South portion a well done consolidated area more appropriate to land occupation resulting in facilities to access services and infrastructure as well. The biggest problems are in the Northern-part that beyond to be areas with an accentuated declivity, are irregularly occupied with no infrastructure or governmental assistance planning. Due to the occupation stress in the Northern portion were analyzed three micro basins belonging to the Fortaleza with different historical occupations resulting in a short term in an environmental degradation especially regarding to dynamic surface. To elaborate the Environmental Degradation Map were used the method the Compartimentation Basic Units. The obtained datas suggest that the basin suffer with the environmental degradation revealed in dynamic surface problems such as slide, a great volume of silting, mainly of the alluvial plains. The absence of planning and infrastructures in these places assure to an increase of this degradation, requiring geotechnical cartography in order to help the government to go on in a best way to use the land and manage the existing problems.
