14. Uso de imagens MODIS no mapeamento de bacias hidrogrÃficas
This research focuses on display applications of MODIS (Moderate Resolution Spectroradiometer) and the different types of its products. The MODIS was design for analysis of changes on a global scale, thus having different environmental applications. This sensor has 36 bands and 44 products for different types of searches. The spatial resolution of MODIS imag

15. Avaliação da qualidade de sedimentos - estudo de caso: sub-bacia do Ribeirão Espírito Santo, afluente do Rio São Francisco
This study evaluated the environmental impact resulting from surface water and sediment contamination by metals in a watershed affected by a tailing basin that controls effluents coming from a zinc-ore beneficiation plant. The studies combined assessments of sediment chemistry (exceedances of sediment quality guidelines), benthic assemblage structure and acu

16. Conflitos e gestão de águas : o caso da bacia hidrográfica do rio São Francisco
The management of water resources in Brazil is supported by a legal structure considered a triumph for society because it outlines a management model that establishes an institutional arrangement based on new types of organization for the shared management of water use. Based on principles that promote integrated, decentralized and participative management,

17. Proposta conceitual para a regionalização de vazões / Conceptual proposal for the hydrologic regionalization
The knowledge water availability through hydrographic net is fundamental to management water resources concession use rights. Normally this knowledge is restrict to the places where exist fluviométrica measurement station. Hydrologic regionalization is a technical tool to supply lack of information where there are few or no data availability. From a socio-

18. ComitÃs de bacias hidrogrÃficas de rios do MÃdio SÃo Francisco: possibilidades e desafios de GestÃo do Uso da Ãgua. / Water Basin Committees of rivers of MÃdio SÃo Francisco: opportunities and challenges of managing the use of water
O presente estudo tem como tema a gestÃo das Ãguas, que se tornam cada vez mais escassas em funÃÃo da incompatibilidade entre a quantidade e a qualidade da Ãgua disponÃvel com a crescente demanda da populaÃÃo. Tal escassez desse vital recurso hÃdrico, tanto em termos quantitativos quanto qualitativos, acaba por desencadear conflitos entre os diferen

19. DiagnÃstico do uso e ocupaÃÃo do solo na bacia hidrogrÃfica do Rio SÃo JosÃ, Cascavel â PR.
The use of soil is understood as a space that is being occupied by man, developing a set of activities of production and reproduction of a society, involving both urban and agricultural areas. Due to the economic development of the last few years, this subject has been studied more and more with a common concern: the quality of water. The objective of this p

20. Migração e conservação do dourado (Salminus franciscanus, Lima &Britski 2007) em um trecho do Rio São Francisco
Dourado (Salminus franciscanus) is one of the most important fish for commercial and 2 recreational fisheries of the São Francisco river basin. From late 2005 to early 2007, dourados (n=107) were captured near the Abaeté river mouth (Pontal), tagged (n=41) and tracked 4 (n=33) in the São Francisco river between the cities of Três Marias and São Romão.

22. 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.

23. Tratamento estatístico dos parâmetros da qualidade das águas da bacia do alto curso do Rio das Velhas
Water quality was monitored at the upper course of the Rio das Velhas, a major tributary of the São Francisco basin located in the state of Minas Gerais, over an extension of 108 km from its source up to the limits with the Sabara district. Monitoring was done at 37 different sites over a period of 2 years (2003-2004) for 39 parameters. Multivariate statist

24. Avaliação e redimensionamento de redes para o monitoramento fluviométrico utilizando o método sharp e o conceito de entropia
Information of the hydrologic regime characteristics of the watercourses in a hydrologic basin are the starting point for developing water resources management actions taking its multiple uses into account. Setting up of such knowledge is carried out by means of information about the river discharges during certain period through the settlement of monitoring
