3. Multivariate Analysis of Erosivity Indices and Rainfall Physical Characteristics Associated with Rainfall Patterns in Rio de Janeiro
ABSTRACT The identification of areas with greater erosive potential is important for planning soil and water conservation. The objective of this study was to evaluate the physical characteristics of rainfall events in the state of Rio de Janeiro, Brazil, and their interactions with rainfall patterns through multivariate statistical analysis. Rainfall depth,

4. Spatial Distribution of Annual and Monthly Rainfall Erosivity in the Jaguarí River Basin
ABSTRACT The Jaguarí River Basin forms the main water supply sources for the São Paulo Metropolitan Region and other cities in the state. Since the kinetic energy of rainfall is the driving force of water erosion, the main cause of land and water degradation, we tested the hypothesis of correlation between the erosive potential of rainfall (erosivity) and

5. Spatial Interpolation of Rainfall Erosivity Using Artificial Neural Networks for Southern Brazil Conditions
ABSTRACT Water erosion is the process of disaggregation and transport of sediments, and rainfall erosivity is a numerical value that expresses the erosive capacity of rain. The scarcity of information on rainfall erosivity makes it difficult or impossible to use to estimate losses occasioned by the erosive process. The objective of this study was to develop

6. Efeito do selamento superficial na condutividade hidraulica saturada da superficie de um solo cerrado.
Com o objetivo de quantificar o efeito do selamento superficial na condutividade hidraulica saturada (Ko) da superficie de um Latossolo Vermelho-Amarelo de cerrado, foram submetidas amostras de solo indeformadas de tres diferentes condicoes de manejo, a saber: solo sob sistema de cultivo tradicional, plantio direto e cerrado virgem, com nove repeticoes sob c

7. Desempenho de plantas de cobertura no controle da erosão hídrica no Sul de Minas Gerais / Performance of cover crops to control erosion in the South of Minas Gerais
The erosion initiates with the impact of the raindrop on the soil surface, causing the transport of sediment, nutrients and organic matter. To reduce this erosion, the use of conservation practices, such as proper management and planting of cover crops that reduce these losses, is essential. The objective of this study was to evaluate the potential of plant

9. EROSIVIDADE, COEFICIENTE DE CHUVA, PADRÕES E PERIODO DE RETORNO DAS CHUVAS DE QUARAI E RIO GRANDE, RS / EROSIVITY, RAINFALL COEFFICIENT, PATTERNS AND RAINFALL RETURN PERIOD OF QUARAI AND RIO GRANDE, RS
The rainfall specifics characteristics vary from one region to another. The knowledge of the rainfall potential to cause erosion is necessary to plan agricultural and civil engineering activities. For Quarai and Rio Grande (RS, Brazil), were determined the rainfall erosivity and its relationship with precipitation and rainfall coefficient, rainfall patterns

10. Tratamento de chorume de aterro sanitario usando eletrolise foto-assistida / Treatment of landfill leachate by photo-assisted electrolysis
Sanitary landfills are the major method used today for the disposal and management of municipal solid waste. Decomposition of waste and rainfall generate leachate at the bottom of landfills, causing groundwater contamination. The leachate is a dark grey, foul smelling solution and it can be considered a complex effluent, often containing organic compounds, h

11. Variações interanuais da circulação geral de inverno no Hemisfério Norte e da oscilação sul (Meridional) e suas possíveis conexões com o clima do nordeste Brasileiro / Interannual variations of winter general circulation in the North Hemisphere and South oscillation (Meridional) and its possible connections with the Northeast Brazilian
Interannual variations of the winter circulation in the Northern Hemisphere (NH) and their possible connections with the interannual variation of the precipitation in Northeast (NE) Brazil are studied. The data set used for the NH circulation are the winter grid point geopotential height of the 700mb for the period 1964-82 (19 years). These grid point data a
