1. Processos hidrológicos em uma sub-bacia do Parque Estadual da Serra do Mar, núcleo Santa Virgínia
Resumo O presente estudo busca caracterizar o funcionamento hidrológico de uma sub-bacia com cobertura de Mata Atlântica, localizada no Parque Estadual da Serra do Mar, núcleo Santa Virgínia. Para isso, foram monitorados entre os anos de 2008 e 2009, alguns processos hidrológicos: escoamento superficial, umidade do solo (0,15, 0,30, 0,50 e 0,90 metros d

2. Impacts of land-use change on southeast Amazonia basin streamflow
Resumo A Região Amazônica vem despertando interesse crescente da comunidade científica internacional devido às amplas possibilidades ambientais que suas densas florestas têm a oferecer no que diz respeito à regulação climática e recursos hídricos. Apesar dos muitos esforços de agências reguladoras de meio ambiente e centros de pesquisa, esta regi

3. Efeitos da espacialização da cobertura florestal e da profundidade dos solos na produção de água de uma bacia hidrográfica / Effects of the spatial distribution of forest cover and the soil depth in water yield of a watershed
Several works related to the theme of water production are being made, having in common the association of forest cover with runoff in watersheds. However, no studies were found where the places where this land cover has optimum effect, because it is dependent on climatic and physiographic conditions of each watershed. The objective of this study is to evalu

4. Comparação entre diferentes interpoladores na delimitação de bacias hidrográficas.
ABSTRACT: The morphometric parameters are of fundamental importance for the good operation of models, among them, the area of the basin to amount determined for each pixel stands out for releases use in hydrologic models used for the definition of saturation areas in the landscape and predictive models of mass movements. In this work three different ways are

5. Modelagem hidrológica dinâmica distribuída para estimativa do escoamento superficial em uma microbacia urbana
- Floods and inundations are serious problems in Brazilian cities as a result of inappropriate urbanization processes. Impervious surface reduces or makes water infiltration impossible, leading to significant increases in surface runoff. Considering this scenario, this work aims at applying a dynamic distributed hydrological model in order to estimate surfac

6. Análise das relações climato-hidrológicas e das demandas hídricas no alto curso da bacia hidrográfica do Rio Bagagem/MG
The rational searching for rational use of the hidric resources motivated this thesys whose objetctive was to know the climate-hidrologic processes that happen inside a hidrografic basin by the human interference in the environment. The understanding of those processes propitiated subsidies for the understanding of the space organization of the area, mainly

7. A utilizaÃÃo da microalga skeletonema costatum (greville) cleve (bacillariophyceae) na avaliaÃÃo da qualidade ambiental de Ãreas estuarinas de Pernambuco
Coastal environments are characterized by the high complexity and biological diversity, where the variety overcomes others ecosystems. The estuaries represent one of the most productive ecosystems of the world, due to the great contribution of inorganic dissolved nutritients, coming from the continent. It has been changing in the last years, as a result of a

8. A planície aluvial do médio rio araguaia: processos geomorfológicos e suas implicações ambientais / The alluvial plain of the middle Araguaia River: geomorphological processes and their environmental implications
The Araguaia River is the most important fluvial system of South America. With an area of 380.000Km, its includes two phytogeography regions that have a good part of planet biodiversity: Cerrado, in the south, and Amazonia Forest, in the north of Brazil. The high level of Cerrado ecosystem destruction and changes in the land using, after 1965, promoted an in

9. Abordagens qualitativa e quantitativa de micro-bacias hidrográficas e áreas alagáveis de um compartimento do Médio Mogi-Superior/SP / Qualitative and quantitative approaches to the hydrographic microbasins and floodable areas of a compartment of the Mid-Upper Mogi Guaçu river, SP, Brazil
The search for tools that contribute to enhance the interpretation of information about the diverse uses of soil and their consequences on aquatic bodies is an important task, since the qualities of soil and water have always affected human civilization. The goal of the present work was to quantify, by a first approximation and based on existing data, the er

10. Verificação de parametros hidricos da Bacia do Rio Jaguari no municipio de Jaguariuna / The verification of hydric parameters in the Jaguari river s Basin in Jaguariuna country
The increasing demand of the hydric resources requires the development of efficient mechanisms to the management of those resources. The implantation of hydric resources management guidelines needs practical and efficient instruments to help when taking decisions. In this research it is proposed, as an auxiliary instrument in the hydric resources management,

11. Implicações tectônicas na hidrologia do aqüífero Barreiras e sistema lacustre do Bonfim, Nísia Floresta-RN
This MSc dissertation presents the results of a research carried out in a 500 km2 area in the Nísia Floresta county. The main goal of the research was to evaluate fault influence on hidrology features of aquifers and lakes, mainly in the Barreiras Group and in the Bonfim lake cluster respectively. The Precambrian crystalline basement is made of Caicó Compl

12. Attributes of an alluvial river and their relation to water policy and management
Rivers around the world are being regulated by dams to accommodate the needs of a rapidly growing global population. These regulatory efforts usually oppose the natural tendency of rivers to flood, move sediment, and migrate. Although an economic benefit, river regulation has come at unforeseen and unevaluated cumulative ecological costs. Historic and c
