Caracterização ambiental da Sub-bacia do Rio Claro, no município de Santa Rita do Passa Quatro - SP

Abstract

The rapid growth of the population, combined with socioeconomic activities, results in a continuous and intense pressure on natural resources, causing transformations in the units of a given environment. In this context, the objective of this research was to characterize the physical elements that make up the Sub-Basin of Rio Claro, located in Santa Rita do Passa Quatro, SP, seeking thematic mappings to aid in a better visualization of the space and analysis of the components, being necessary understand the influence that the area surrounding this basin exerts on the municipality. For this, the influence of hydrography, slope, soil types, hypsometry, relief forms and land use and occupation that directly affect the location were analyzed. This influence was evaluated in terms of the dynamics of the topography and also the urban expansion in the area. Finally, the analysis of the information collected indicated points that present a medium to high degree of fragility, both potential and emerging, being these places susceptible to processes of environmental impacts such as erosion, silting, degradation of APPs, among others. The need for reassessment of land use and occupation is then verified, and it is revealed that the work can support future planning and territorial management projects in the municipality.
