The Paulista West region has suffered through the decades an intense process of deforestation when substituting native areas of Atlantic rainforest and Cerrado by agricultural cultivation, mainly coffee in the 20th century. This occupation process without planning and management of the soil resulted in serious erosion problems. Besides, the soil erosion promoted the reduction of agricultural production and the silting of rivers. This paper aims identify the factors of natural scope (geological, geomorphologic and pedologic characteristics) which participate in unleash of erosion process in two agricultural properties producers of coffee in order to apply mechanical techniques of recovery in erosive focuses of furrow and ravine kinds. One of the properties is at the city council of Getulina, located on the sandstones of Adamantina Formation; the other is at the city council of Vera Cruz, located on the sandstones of Marília Formation. However, taking into consideration the analysis of the natural dynamics, they are not enough to explain the complexity of the phenomena which are processed in the geographic space. It made indispensable the incorporation of socio-economic factors, such as the use and occupation process of the soil considering the society as landscape transformers. In order to better understand the importance of each one of the elements that contributes to the unleash of the studied erosions, it was collected soil samples in the areas, general descriptions and texture and morphologic analysis. Finally, it was elaborated the maps of the use and occupation of the soil and the vegetal coverage surrounding the properties studied. It was observed in the rural property of Getulina the substitution of the coffee by pasture that finds degraded. It, in addition to the cattle stomp, which changed the texture and density characteristics among the soil horizons, and the concentration of superficial water flow intensified the occurrence of ...

As unidades de paisagens naturais se diferenciam pelo relevo, clima, cobertura vegetal, solos ou até mesmo pelo arranjo estrutural e do tipo de litologia. A caracterização pedológica e o entendimento das relações entre pedologia, geologia e geomorfologia são importantes para a compreensão da distribuição dos solos numa paisagem. Considerando esta como sendo uma combinação dinâmica e instável de elementos físicos, biológicos e antrópicos, e estando em constante evolução, realizou-se o estudo das características químicas, físicas, mineralógicas e morfológicas das coberturas superficiais de uma mesma Unidade Fisiográfica na região do Planalto Ocidental e da Depressão Periférica Paulista nas proximidades de Rio Claro – SP, para a compreensão de suas relações genéticas e cronológicas na evolução das paisagens da área. Para isso foram comparados os solos de dois transectos dentro dos compartimentos, levantando e analisando as características citadas para que se possa obter informações que permitiram o diagnóstico da evolução da área, visando contribuir para o avanço das coberturas superficiais e sua relação com a evolução da paisagem. Foi possível compreender determinados processos e produtos que deram origem às coberturas superficiais e consequentemente a algumas paisagens representativas da Quadrícula de São Carlos a partir dos métodos empregados. O estudo das coberturas de alteração intempérica da região centro-oeste paulista, e seu reconhecimento, são fundamentais para o ordenamento territorial e seu planejamento regional

The study of mathematical modeling assists in evaluation of the capacity of production and measurement of generation time of biogas in landfills, enabling the implantation of projects of energy generation from methane. Thus, the work aims, by simulating scenarios of potential methane generation in the landfill in Rio Claro, the use of field data from methane flow and waste grounded parameters as references for selecting values of k e L0 used to estimate methane generation model in LandGEM. As a result it was found that compared the characteristics adopted in the four scenarios recommended by the USEPA literature with those found in the landfill of Rio Claro (high amount of organic matter in the waste landed and daily practice of leachate recirculation), the scenario that apparently better represent the rate of methane generation is the scenario 01, with k = 0.7 and L0 = 96. Now, the adjustment of parameters in relation to the data field of methane flow, the value of L0 which best fits the methane generation from the landfill in Rio Claro is 150, while for k the line behavior that best represents the reality are values between 0.7 and 0.3. Regarding the parameters of the waste grounded, between the suggested values of k, 0,3 is most consistent with the intermediate level of biological degradation of the residue grounded, while L0 due to the biodegradability of the waste, a new value between 120 and 150 may be more appropriate for the study

The term model refers to any representation of a real system. The use of models in Hydrogeology can be valuable predictive tools for management of groundwater resources. The numeric models of groundwater flow, object of this study, consist on a set of differential equations that describe the water flow in the porous medium. In this context, numeric simulations were made for a sub-basin located at Cara Preta farm – Santa Rita do Passa Quatro – SP. The aquifer at the local is composed by rocks of Pirambóia Formation, which is part of Guarani Aquifer System. It was developed a conceptual model from previous studies in the area, and from that, simulations were made through the software Visual Modflow®. The conceptual model established previously was considered consistent through the results of simulation.
