1. Sediment production and soil water infiltration under different simulated rainfall characteristics
RESUMO O estudo foi realizado com objetivo de avaliar a produção de sedimentos, a infiltração da água e o escoamento superficial em um Argissolo Vermelho-Amarelo sob chuvas simuladas com erosividades semelhantes, mas com distintas combinações de intensidade de precipitação (Int) e duração (Dur). As chuvas foram aplicadas após o preparo do solo e

2. 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,

3. Avaliação da produção de sedimento na bacia hidrográfica do rio Potengi através do modelo SWAT
Anthropic disturbances in watersheds, such as inappropriate building development, disorderly land occupation and unplanned land use, may strengthen the sediment yield and the inflow into the estuary, leading to siltation, changes in the reach channel conformation, and ecosystem/water quality problems. Faced with such context, this study aims to assess the ap

4. 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

5. 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

6. Modeling spatial of water erosion in the Doce River Valley, Central-East region of Minas Gerais state â Brazil / Modelagem espacial da erosÃo hÃdrica no Vale do Rio Doce, regiÃo Centro-Leste do estado de Minas Gerais
Minas Gerais à o estado com maior Ãrea de florestas plantadas no Brasil, grande parte desses plantios encontra-se na regiÃo do Vale do Rio Doce, MG. Essa regiÃo Ã, atualmente, das mais degradadas pela erosÃo hÃdrica no estado. Como forma de auxiliar na identificaÃÃo de Ãreas com menor e maior suscetibilidade a erosÃo hÃdrica e a compreender os me

7. THE UNSUSTAINABILITY OF SOIL USE WITH TABACCO CROP ON STEEP SLOPES / A INSUSTENTABILIDADE DO USO DO SOLO COM FUMICULTURA EM TERRAS DECLIVOSAS
Areas susceptibility to water erosion and strong pressure of soil use, as in Southern Brazil, where there is cultivation of tobacco, are prone to degradation of the natural resources. The objective of this dissertation was to evaluate the unsustainability of the natural resources in a watershed under tobacco production, characterized by steep slopes, with in
