3. Water Erosion in Oxisols under Coffee Cultivation
ABSTRACT Water erosion is one of the main environmental impacts of land use. When soil and water losses occur, nutrients essential for the growth and maintenance of plants are removed, with harmful outcomes on the sustainability of agriculture and the environment. In addition, they lead to other deleterious effects, such as sedimentation and eutrophication o

5. 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

6. Atuação dos Subcomitês da Bacia Hidrográfica do Rio das Velhas na gestão dos recursos hídricos
Os Subcomitês são ferramentas importantes na gestão de recursos hídricos do Comitê da Bacia Hidrográfica do Rio das Velhas. Esses órgãos são entidades consultivas e propositivas que funcionam obrigatoriamente com a participação dos três segmentos da sociedade (poder público, usuários da água e sociedade civil organizada), constituindo um avan�

7. Avaliação e identificação de parâmetros importantes para a qualidade de corpos d'água no semiárido baiano. Estudo de caso: bacia hidrográfica do rio Salitre
Objective of this work was identifying superficial water quality parameters, significant to semi-arid hydrographic basins, minimizing costs of water monitoring. The Salitre river basin, an important sub-basin of the São Francisco river, was used as a case study. STD, Cl-, DO, BOD, pH, NO3-, PO4(3-), Al, Cu, Fe, Mn, Ni and Pb were considered the most signifi

8. O ÍNDICE DE SUSTENTABILIDADE AMBIENTAL DO USO DA ÁGUA (ISA) COMO FERRAMENTA DE CONTRIBUIÇÃO ÀS POLITICAS PÚBLICAS DE DESENVOLVIMENTO E CONSERVAÇÃO NA BACIA DO RIO BACANGA, SÃO LUÍS/ MA. / INDEX FOR ENVIRONMENTAL SUSTAINABILITY OF WATER USE (ISA) AS A TOOL FOR CONTRIBUTION TO THE POLICIES PUBLIC DEVELOPMENT AND CONSERVATION IN BACANGA RIVER BASIN, SÃO LUIS / MA.
A hydrographic basin is a complex environmental system, resulting from the interrelations between the physical-natural and socioeconomic subsystems. Its identity as the unifying of environmental processes and human interference is leading to its adoption as a research unit. It allows from the analysis of the physical-chemical, biological and socioeconomic fa

10. Tipologia e fragmentação das terras úmidas do cerrado na alta bacia do Rio Araguaia, estado de Goiás / Typology and fragmentation wetland savanna int he high Araguia River basin, Goiás state
The aim of this research is to call the attention to the humid areas preservation for they are natural habitat with special dynamic and genesis and that they have been damaged by the gradual development of the use of the soil in the latest year. The upper basin of Araguaia river were chosen as an area study to follow systematically the development of Cerrado

Through this study, we aimed at reflecting upon the environmental diagnosis of an urban hydrographic basin. The theoretical approach has been based on the technique of pressure-state-impact-response (PEIR) in order to obtain quality rates through physical, environmental and socioeconomic characteristics of the Arroio Cadena sub-basin located in Santa Maria,

12. Morphological and structural constraints on the dynamics of the river basin of the River Benevente - Espírito Santo / Condicionantes morfológicos e estruturais na dinâmica fluvial da bacia hidrográfica do Rio Benevente - Espírito Santo
The study of watersheds in the humid tropical environment, has acquired great importance in recent decades due to growing demand for water resources planning. However, many studies have confused the concept of watersheds, believing that this was simply a network of interconnected channels that form the hydrography of the land, thus making it as simple cartog
