1. Avaliação dos conflitos no uso da terra na bacia hidrográfica do ribeirão Lamarão, Distrito Federal
Resumo A falta de estudos e a constante degradação das Áreas de Preservação Permanentes (APPs) têm representado um dos maiores entraves para o planejamento de ações conservacionistas, além de favorecer o uso de estratégias inadequadas de manejo das bacias hidrográficas. Dessa forma, este estudo teve como objetivo, delimitar de maneira automática

2. Clay Mineralogy of Basaltic Hillsides Soils in the Western State of Santa Catarina
ABSTRACT A commonly accepted concept holds that highly fertile, shallow soils are predominant in the Basaltic Hillsides of Santa Catarina State, in southern Brazil, but their agricultural use is restricted, either by excessive stoniness, low effective depth or steep slopes. Information about soil properties and distribution along the slopes in this region is

3. Digital soil mapping using reference area and artificial neural networks
ABSTRACT Digital soil mapping is an alternative for the recognition of soil classes in areas where pedological surveys are not available. The main aim of this study was to obtain a digital soil map using artificial neural networks (ANN) and environmental variables that express soil-landscape relationships. This study was carried out in an area of 11,072 ha l

4. Modelagem hidrológica da bacia hidrográfica do rio Bengalas, Nova Friburgo, RJ, utilizando o potencial de geotecnologias na definição de áreas de risco de inundação.
This research focuses on the hydrological study using the potential of geotechnology into runoff modeling of the Bengalas Basin, whose main river, with same name, crosses the city of Nova Friburgo - RJ, in a south-north orientation. This city, one of the most important in "Região Serrana", suffers often with floods and landslides, which, historical data and

5. Evaluation of the lisem model for the simulation of hydrosedimentologic processes in a small rural catchment on the basalt slopes of Rio Grande do Sul, Brazil / Avaliação do modelo LISEM na simulação dos processos hidrossedimentológicos de uma pequena bacia rural localizada nas encostas basálticas do Rio Grande do Sul
The intensive cultivation of the areas of southern Brazil that have poor agricultural potential (shallow soils on steep, basaltic hillsides) has contributed to the degradation of the environment by increasing rates of soil erosion and sediment yields. In this study, traditional monitoring methods have been combined with concurrent mathematical modeling to ve

6. DiagnÃstico do uso e ocupaÃÃo do solo na bacia hidrogrÃfica do Rio SÃo JosÃ, Cascavel â PR.
The use of soil is understood as a space that is being occupied by man, developing a set of activities of production and reproduction of a society, involving both urban and agricultural areas. Due to the economic development of the last few years, this subject has been studied more and more with a common concern: the quality of water. The objective of this p

7. Water Balance Model in a watershed micro basin covered by eucalypt culture / Modelagem do balanço hídrico em microbacia hidrográfica com plantio eucalipto
Every production tasks such as the raw material woods - growth using homogeneous reforestation and species that show quickly grow has caused environmental impact. The homogeneous reforestation, showing quick growth, has been considered in many studies because of its environmental impact and water consumption. This works purpose is to improve the water balanc

In spite of the great importance of the soil organic matter for the sustainability of the natural systems and of agricultural production, its study remains incipient in the area of the Edge of the Rio Grande do Sul Plateau, where different research have been reporting negative aspects of the inadequate soil use. In that sense, the carbon distribution evaluat

11. A paisagem como elemento de sustentabilidade do Vale do RibeirÃo da Prata
The Vale do RibeirÃo da Prata is located in the edges of the Bulk of the MaciÃo de PoÃos de Caldas, in the cities of Ãguas da Prata and SÃo JoÃo da Boa Vista. The valley is part of the Serra da Mantiqueira, region of mounts, with hillsides of accented declivity and is formed by a great amount of springs that if originate in the hillsides and the tops o
