1. ASSESSMENT OF SOIL LOSS SUSCEPTIBILITY IN SANTA RITA WATERSHED IN SOUTHERN BRAZIL
ABSTRACT Estimation of soil loss susceptibility is of great importance for the management of watersheds. Thus, several models for soil loss prediction have been proposed. This study estimated the total annual soil loss for the Santa Rita watershed, located in southern Brazil, using the Revised Universal Soil Loss Equation. In addition, a classification to so

2. Modeling of Soil Losses on a Yellow Argisol Under Planted Forest
ABSTRACT Erosion prediction models are a useful tool for soil use planning and soil conservation. This study aimed to apply the Universal Soil Loss Equation (USLE) in an experimental sub-basin located in the municipality of Teixeira de Freitas, in the southern end of the state of Bahia, Brazil. The following variables were calculated: rainfall erosivity fac

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

4. MODELING OF PHOSPHORUS LOSSES BY WATER EROSION
ABSTRACT Phosphorus losses in runoff water and eroded sediment may increase the risk of eutrophication. Erosion prediction models can be used to assess and quantify nutrient losses and transport in different soil management scenarios. This study aimed to assess the performance of models to estimate the losses of available phosphorus in eroded sediments and a

5. 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

6. Water Erosion in Different Slope Lengths on Bare Soil
ABSTRACT Water erosion degrades the soil and contaminates the environment, and one influential factor on erosion is slope length. The aim of this study was to quantify losses of soil (SL) and water (WL) in a Humic Cambisol in a field experiment under natural rainfall conditions from July 4, 2014 to June 18, 2015 in individual events of 41 erosive rains in th

7. The relation between dermoscopy and histopathology of basal cell carcinoma
Abstract BACKGROUND: Basal cell carcinoma is the most frequent cancer in fair-skinned populations and dermoscopy is an important, non-invasive technique that aids in the diagnosis of Basal cell carcinoma. OBJECTIVES: The aim of this study was to evaluate the relationship between histopathological subtypes and dermoscopic features of Basal cell carcinoma. MET

8. Avaliação de modelos de elevação na estimativa de perda de solo em ambiente SIG / Elevation models on the prediction of soil loss on a GIS environment
The present study assessed the use of the terrain elevation models ASTER GDEM and SRTM in replacement of the topographic charts on 1:10000 and 1:150000 scales, as data for predicting soil loss on small watershed basin. All the altimetry data and further information were incorporated to the GIS/SPRING. For estimating the soil erosion it was necessary to estab

10. Potencial impacto das mudanças climáticas nas perdas de solo e água na microbacia do córrego Jaqueira, Alegre - ES. / Potential impact of climate change on soil loss and water in the watershed of the córrego Jaqueira, Alegre - ES.
O controle do processo erosivo requer o entendimento das interações complexas entre os processos químicos e físicos do solo, além dos hidrológicos e meteorológicos. Diversos modelos matemáticos vêm sendo desenvolvidos e aperfeiçoados com o objetivo de prever a magnitude das perdas de solo por erosão, como o Water Erosion Prediction Project (WEPP).

11. Superfosfato triplo, lama vermelha e zeólitas para remediação de metais pesados em solo contaminado / Remediation of contaminated soil with heavy metal using triple superphosphate, red mud and zeolites
Due to the heavy metal persistence in soils, the contamination by these elements is considered permanent and might result in great impact causing a degradation of the chemical and biological properties of the soil. Stabilization techniques have been used as an efficient tool for the remediation of soils that are contaminated by heavy metals, and they show al

12. Estudo de modelos em ambiente de geoprocessamento para a previsão de erosão e assoreamento de reservatórios : o caso bacia do rio Indaía - uhe três maria, mg / Study on the models for predicting soil erosion and siltation of reservoirs : the case of the Indaiá river basin - uhe três marias, mg
A bacia do rio Indaiá é uma importante contribuinte do reservatório da UHE Três Marias-MG, notavelmente pela sua localização em relação ao barramento e por suas altas taxas de produção de sedimentos, consequência de um contexto histórico de intensas atividades antrópicas. Esta pesquisa teve como objetivo estudar diferentes modelos em ambiente de
