25. Diagnóstico hidrossedimentológico da Bacia do Rio Piquiri.
RESUMO: O conhecimento do comportamento hidrossedimentológico de uma bacia hidrográfica é fundamental para a adequada gestão e uso de seus recursos hídricos. Este traballho objetivou realizar, a partir dos dados hidrossedimentométricos da Bacia do Rio Piquiri, um diagnóstico sobre o seu comportamento hidrossedimentológico. Utilizando os dados fluviom

26. Desenvolvimento e aplicação de procedimento metodológico em suporte ao planejamento participativo para redução de perda de solos em pequenas bacias hidrográficas com emprego da EUPS
The agrosilvipastoral activity has impacted negatively the environment worldwide, promoting soil erosion and sediment settling in water bodies. The Universal Soil Loss Equation (USLE) estimates the rates of laminar erosion (A; in ton/acre/year) by the multiplication of six parameters: A = RKLSCP (R: rainfall erosivity factor; K = soil erodibility factor; S:

27. Sistema integrado de informações para preservação de recursos hídricos em unidades de conservação / Integrated information system for protecting water resources in protected areas.
The increasing demand of mankind by use of water quality and sufficient volume to meet their needs in their different uses, shows that water resources must be managed and preserved. A watershed is the physical unit that integrates the entire flow of water that makes up the hydrological cycle, but its use is being carried out in a disorderly way, without comp

28. Proposição preliminar de indicadores como instrumento de manejo integrado da microbacia hidrográfica do Ribeirão da Cachoeirinha e do Córrego do Meio, no bairro de Catuçaba, São Luiz do Paraitinga, SP / Preliminary Proposal of Indicators as an Integrated Management Instrument of Cachoeirinha and Córrego do Meio Creek Watersheds, Catuçaba District, São Luiz do Paraitinga, SP
The modern problems are complex and require solutions that reflect impacts on socioeconomic, environmental, and political-institutional aspects in terms of their different degrees of importance. Within this context, a crosscutting analysis of concepts related to sustainable development, sustainable agriculture, watershed structure, and the use of indicators

29. Análise multitemporal da susceptibilidade erosiva na bacia do Rio Urucuia (MG) por meio da equação universal de perda de solos
The Universal Soil Loss Equation (USLE) is an erosion model to estimate average soil loss being as a product of rainfall runoff erosivity factor R, soil erodibility factor K, slope length factor L, slope steepness factor S, cover management factor C, and support practice factor P. Beyond this methodology to predict soil loss, it has been extended as a useful

30. Institutional actions, participatory approach and environmental conflicts in the Moinho Stream Watershed, Nazaré Paulista - SP / Ações institucionais, participação e conflitos ambientais na sub-bacia hidrográfica do Ribeirão do Moinho, Nazaré Paulista - SP
This project uses as core study area the Moinho Stream Watershed located in Nazaré Paulista, São Paulo State, Brasil, which is part of the Cantareira System Environmental Protected Area. This region contains springs and watersheds of regional importance, which, associated with its natural beauty, are transforming it in real estate targets, increasing a dis

31. Análise fluviológica e ambiental da bacia hidrográfica do rio Jaú - SP
The fluviological analysis is an important tool for planning and managing watersheds once that, by means of the characterization of discharges regime and the pulse of a water curse, it helps to indicate their hydrological state and the contributes to handle the natural resources with focus on ecosystemic services. Using secondary data and knowledge of statis

32. Rainfall distribution evaluation in the urban peaks discharges using radar and rain guage data / Avaliação da distribuição da chuva nas vazões maximas urbanas usando dados de radar e de pluviografo
A precipitação é um componente do ciclo hidrológico que apresenta grande variabilidade espacial. Postos pluviométricos fornecem registros válidos apenas para um pequeno entorno do instrumento. A baixa densidade e as curtas séries de dados dos postos pluviométricos em bacias brasileiras tem sido fatores determinante nas incertezas dos resultados de di

33. Valuation of Atlantic Forest environmental services in the water quality and quantity of the Sana EPR. / Valoração dos serviços ambientais da Floresta de Mata Atlântica associados à qualidade e quantidade da água na APA do Sana.
The study evaluated the relationship between soil coverage and the quality and quantity of water in watersheds in order to assess the environmental services of the Atlantic Forest in two micro basins. The micro basins Palmital and Glória are located in the Sana Environmental Protection Area (EPR), municipality of Macaé (RJ). They are covered by different p

34. Sistema Web-GIS participativo associado a indicadores de gestão descentralizada de risco de inundações / A participatory web-GIS system associated to decentralized flood risk management indicators
This dissertation presents the development and application of an interactive web-GIS in which internet users map flood risk collaboratively by filling up a geotagged form with questions on flood hazard, exposure and vulnerability. Flood risk was also assessed through the use of a set of environmental risk indicators proposed by Mendiondo (2008). The two meth

35. Sediment yield in watersheds under different geo-environmental contexts: measured and modelling / ProduÃÃo de Sedimentos em Bacias HidrogrÃficas Sob Diferentes Contextos Geoambientais: Medida e Modelagem.
Sediment yield assessment is necessary in watersheds when it is desired to improve the quality of analysis, contributing for a consistent evaluation of water availability and, therefore, high-quality water resources management. The general objective was to evaluate the sediment yield in watersheds under different geo-environmental contexts. Three small basin

36. Conceitos e técnicas para assentamentos humanos na perspectiva da sustentabilidade
The research is based on an analysis of the changes that are occurring in trying to adapt the limitations of the planet facing the constant demands of humanity. After an initial analysis of the problems of growth of cities and the exploitation of natural resources, there is a major historical events and documents produced in the environmental area and presen
