Influências geogênicas/antropogênicas na composição química das águas pluviais de Dois Córregos, bacia do Rio Jaú (SP)

Thirty-seven rainwater samples were collected at Jaú River watershed, Dois Córregos city (SP), between August 2009 and July 2010, where were analyzed the following variables: pH, Na+ , K+ , Ca2+, Mg2+, NO3- , Cl- , SO4 2- , PO4 3- and SiO2. The results indicate that Ca2+ (6.65%) and NO3- (35%) are the most abundant ions that followed the trend: Ca2+ > Mg2+ > K+ > Na+ for cations and NO3 - > SO4 2- > Cland PO4 3- for anions. The phosphate fertilizers use, agricultural soils dust, lithology, biomass burning and fossil fuels can be the major contributing factors to explain the chemical composition of rainwater at Jaú River watershed, Dois Córregos city (SP).

Comparative analysis between biogas flow in landfill and electrical resistivity tomography in Rio Claro city, Brazil

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.

Recomposição florestal visando à conservação de recursos hídricos na bacia do Rio Pardo, SP

The Pardo River Basin represents the situation of disorderly process of use and occupation of land, where forest fragmentation is one of the results. This study evaluated the use of Multicriteria Evaluation in a GIS, specifically through method Weighted Linear Combination, the generation of map of priority areas for forest restoration in the initial part of Rio Pardo Basin, SP, aiming the conservation of water resources. It can be concluded that, the Multicriteria Evaluation in a GIS is appropriate to the mapping of priority areas for forest restoration. The map of suitability for forest recovery may be useful in the environment planning, providing public and environmental agents making decision, based on a method that takes into account the landscape as a whole and the priority is the conservation of water resources.
