RESUMO

This thesis presents an integrated study of the geological and geotechnical characteristics of São Carlos region which influence the recharge process of the aquifer composed of sandstones of the Botucatu Formation. Among the assessed characteristics, it can be distinguished the parameters of ydraulic conductivity, retention of pollutants and pore distribution, also information about the distribution and occurrence of the geologic materials, groundwater depth, land use and water diffraction surfaces. Such data were obtained from desk study, field and laboratory integrated works, with the results being generated in the form of maps considered fundamental to the development of models for recharge assessment. In the region, it was also conducted monitoring of rainfall, groundwater levels and water content of the unsaturated zone through pluviograph, monitoring wells and tensiometers, respectively. The integrated information and monitoring data were used in the Mike-She software simulations, which considered the different geological and geotechnical aspects in the study for assessment of the recharge rates. The study demonstrated the importance of variability of geological materials, geological and geotechnical characteristics and dynamics of water for the adequate assessment of the aquifer recharge and transport of pollutants.
