2. Variabilidade oceânica associada à variabilidade climática da vazão na bacia do rio São Francisco / Oceanic variability related to river outflow at São Francisco Hydrographic basin
This research concerned to propose a valuation about the relationship between annual oceanic behavior and river outflow at São Francisco Hydrographic Basin, in Brazil, for the period from 1968 to 2004. Linear model based on multiple regression were built for annual river outflow at Ponte da Taquara, located at High São Francisco sub-basin. Climatic indexes

3. Mithracinae (Decapoda: Brachyura) from the Brazilian coast: review of the geographical distribution and comments on the biogeography of the group
The geographical distribution of marine organisms, as a result of complex natural processes through geological time, has been changed, sometimes drastically, by species introductions. Instances of species introduction have been recorded worldwide, and the Brazilian coast is no exception. The present review provides an update of the geographical distribution

4. OUTFLOW FORECAST BASED ON ARTIFICIAL NEURAL NETORKS AND WAVELET TRANSFORM / PREVISÃO DE VAZÃO POR REDES NEURAIS ARTIFICIAIS E TRANSFORMADA WAVELET
The hydroelectricity system is responsible for 83.7% of the electric energy generated at Brazil. Therefore, the generation of electric power in Brazil depends basically on the natural flow rates distributed by twelve basins in the country. The quality of prediction of natural flow is of crucial importance for the Brazilian governmental agency, ONS (from the

5. Dinâmica do uso dos recursos hídricos nas bacias do ribeirão Entre Ribeiros e do rio Preto, afluentes do rio Paracatu / Water resources use dynamics in watersheds of Ribeirão Entre Ribeiros and Rio Preto, tributaries of the Paracatu River
From times past, humanity confronts problems of environmental degradation. The environment, which always performed efficiently its function of filtration, today finds itself excessively overburdened by human activities: it suffers the risk of its resources exhausting, not being able in certain situations to recuperate itself and needing the help of man.

6. Hydrological potential of the Monte Olimpo watershed on Campus Luiz de Queiroz of the University of São Paulo / Potencialidades hídricas da microbacia hidrográfica do córrego do Monte Olimpo no campus "Luiz de Queiroz" da Universidade de São Paulo
The goal of this work was to study the hydrological potential of the Monte Olimpo Watershed on Campus Luiz de Queiroz of the University of São Paulo. This watershed is located entirely on the Campus, where good water quality can be stored in two reservoirs. Due to the lack of soil conservation practices and environment concerns this watershed is much degrad

7. Heterogeneidade espacial e a qualidade das águas superficiais do Reservatório Guarapiranga (São Paulo-SP-Brasil) / Spatial heterogeneity and water quality of superficial water at the Guarapiranga reservoir (São Paulo-SP- Brazil)
Environmental heterogeneity studies are of great importance in ecology, once it interferes on ecosystems structure and working. Water reservoirs in particular are artificial ecosystems with high spatial and temporal heterogeneity. To test the hypothesis of existence of a pattern of longitudinal heterogeneity, and discuss water quality according to CONAMA 357

8. Water quality assessement and water conditions for recreational use in basin of the Carrancas River - MG / AvaliaÃÃo da qualidade das Ãguas e condiÃÃes de balneabilidade na bacia do RibeirÃo de Carrancas-MG
The development of anthropogenic activities without an adequate planning has provided the degradation of waters quality, compromising the several uses of this natural resource, as its utilization for recreational use. In this context, the county of Carrancas, located in the southern area of Minas Gerais state, possesses various natural attractions, such as s

9. Antropização da bacia hidrográfica do rio Miranda: alterações climáticas, recursos naturais e desenvolvimento
The present study it objectified to analyze the behavior of the meteorological parameters, identifying the climatic changes inside of the Hydrographic Basin of Miranda River and relating such changes to the deforestation taxes and its consequences for the local communities. The related changes are associates to the evolution of the deforestation modifying th

10. Study of amazon floodplain water composition using hyperion/EO-1 and field reflectance data for the comprehension of temporal variability of optically active constituents / Estudo da composição das águas da planície amazônica por meio de dados de reflectância do sensor hyperion/EO-1 e de espectrômetro de campo visando a compreensão da variação temporal dos seus constituintes opticamente ativos
Two methodological approaches were evaluated to study the reflectance of optically active constituents using hyperspectral imagery of EO-1 Hyperion orbital sensor: a) Linear Spectral Mixture Model; and b) derivative analysis. Two Hyperion images acquired over an area located upstream of the confluence between the Amazon and the Tapajós rivers were analysed,

11. Simulações dos efeitos da cobertura vegetal no balanço hídrico da bacia do rio Ji-Paraná, RO / Simulations of the effects of vegetation cover in water balance of Ji-Paraná river basin, Rondônia, Brazil
The understanding of how the water balance of a hydrographic basin is affected by the conversion of forests into crops and pasture allow to evaluate the possible impacts of the land use and land cover changes in the regional sustainability. Using a macro-scale hydrologic VIC (Variable Infiltration Capacity) model calibrated for local conditions we simulated

12. Influência de sistemas de vento no deslocamento de água frias na Plataforma Continental Brasileira, utilizando dados AVHRR/NOAA / Influence of Systems of Wind in the Displacement of Cold Waters in the Brazilian Continental Platform, Using AVHRR/NOAA data
An important oceanographic phenomenon observed in the SE/S Brazilian and Uruguayan coasts is the northward intrusion of a surface cold water tongue during the autumn and winter seasons. Past studies indicate that these intrusions have their origin as a combination of La Plata river outflow and the inshore and northward penetration of Malvinas water over the
