The biogas originated from anaerobic degradation of organic matter in landfills consists basically in CH4, CO2, and H2O. The landfills represent an important depository of organic matter with high energetic potential in Brazil, although with inexpressive use in the present. The estimation of production of the productive rate of biogas represents one of the major difficulties of technical order to the planning of capture system for rational consumption of this resource. The applied geophysics consists in a set of methods and techniques with wide use in environmental and hydrogeological studies. The DC resistivity method is largely applied in environmental diagnosis of the contamination in soil and groundwater, due to the contrast of electrical properties frequent between contaminated areas and the natural environment. This paper aims to evaluate eventual relationships between biogas flows quantified in drains located in the landfill, with characteristic patterns of electrical resistivity in depth. The drain of higher flow (117 m3 /h) in depth was characterized for values between 8000 Ω⋅m and 100.000 Ω⋅m, in contrast with values below 2000 Ω⋅m, which characterize in subsurface the drain with less flow (37 m3 /h), besides intermediary flow and electrical resistivity values, attributed to the predominance of areas with accumulation or generation of biogas.

Landscape is the result of interaction between tectonic, weathering and pedogenetic processes, so it is necessary to understand the morphogenesis and relate it to the landforms and landscape. Therefore, this project comprises a geomorphological characterization of some areas associated with the fault zones of Taubaté Basin, at the surroundings of the cities from São José dos Campos to Taubaté SP, emphasizing the Quaternary landscape evolution, where the normal faults played an important role in controling and they were originated, mostly, from the reactivation of Precambrian fault zones by tectonic action. The rift valley scenario is highlighted in the region, identifying the sharp relief from the basin boundary, featuring both Serra do Mar and Serra da Mantiqueira, and a central depressed area where the Taubaté Basin is located. Deforming or modifying basin features are identified, promoting the rearrangement and conditioning of the drainage network and relief, which indicates the presence of morphostructures, conducting to the deduction of a late tectonic process

O presente trabalho teve como objetivo avaliar as variações de uso e ocupação do solo entre os cenários de 2000 e 2011 da microbacia do córrego Monte Belo – Botucatu (SP). Para tanto, utilizou-se de geotecnologias, sendo a integração de informações realizada no Sistema de Informações Geográficas (SIG) - IDRISI, aliada ao uso de cartas digitais do IBGE, escala 1:50.000, além de fotografias aéreas (2000) e imagens de satélite LANDSAT - 5 (2011). Através dos dados obtidos, foram detectadas três classes de uso do solo sendo que em 2000, elas correspondem ao reflorestamento, pastagem e mata ciliar e em 2011, reflorestamento, mata ciliar e solo exposto. Desta forma, pode-se concluir que as ferramentas de análise baseadas em SIGs trazem a possibilidade de analisar as variações no espaço e no tempo além de resultar em informações que podem subsidiar o planejamento da microbacia do Córrego Monte Belo.
