1. Detection of seepage paths in small earth dams using the self-potential method (SP)
Abstract The application of geoelectric methods, such as induced polarization (IP), the electrical resistivity and the self-potential (SP), presents an important indirect study methodology in several areas of geology, such as mining, geotechnics and environmental geology. The present study deals with the results of the application of the self-potential metho

2. Environmental fragility and vegetation cover dynamics in the Lapa Grande State Park, MG, Brazil
Abstract: The environmental fragility analysis evaluates the susceptibility of an environment to degradation. Thus, the goals of this work are to analyze and map the environmental fragility of the Lapa Grande State Park (PELG), Brazil, and its buffer zone (ZA) and also quantify the changes in the vegetation cover before and after the implementation of the PE

3. Comparing blast-induced ground vibration models using ANN and empirical geomechanical relationships
Abstract Blasting remains as an economical and reliable excavation technique, but there are some environmental shortcomings such as the control of blast-induced vibration. The impacts of vibration over surrounding communities in a blast area have been investigated for decades and researchers have been using a myriad of empirical predictive attenuation equati

4. Geology, geochemistry and petrology of basalts from Paraná Continental Magmatic Province in the Araguari, Uberlândia, Uberaba and Sacramento regions, Minas Gerais state, Brazil
Abstract: This study covers the region between the cities of Sacramento and Araguari/Uberlândia (Minas Gerais State, Brazil), where basalt flows from the Paraná Continental Magmatic Province outcrop. The investigated rocks present tholeiitic signature, with high titanium content, and are classified as Pitanga magma-type. The preserved basalt thickness is b

5. Influence of the Transport of Sea Spray on the Salinization of the Semiarid Region Waters (Bahia, Brazil)
The sea spray can be transported to long distances, reaching the semiarid regions. In this work, the rainwater and the atmospheric particulate matter were characterized by investigating the presence of sea spray in the atmosphere of the semiarid region of Bahia, Brazil, aiming to study the influence of its transport on the salinization of the waters of the r

6. 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

7. Modelamento numÃrico do fluxo subterrÃneo atual e simulaÃÃes de cenÃrios futuros da mina de Morro Agudo, Paracatu-MG. / NUMERICAL MODELING OF UNDERGROUND FLOW AND SIMULATIONS OF FUTURE PUMPING SCENARIOS OF MORRO AGUDOÂS MINE, PARACATU-MG
The numerical modeling of underground flow of Morro Agudos mine, property of Votorantim Metais Zinco (VMZ), Paracatu-MG, used data from hydrometeorological monitoring campaigns to calibrate the actual scenario and simulate future pumping scenarios of this mine, using Visual MODFLOW 3.1 software. The study area is located in Paracatu-MG and in external port

8. DIAGNÓSTICO AMBIENTAL DO MEIO FÍSICO DO CAMPO DE INSTRUÇÃO DE SANTA MARIA (CISM) / ENVIRONMENTAL DIAGNOSIS OF THE PHYSICAL ENVIROMENT AT CAMPO DE INSTRUÇÃO DE SANTA MARIA (CISM)
The Campo de Instrução de Santa Maria (CISM) is a military training area for armored troops. Such practices have caused environmental impacts related to the destruction of vegetation, erosion, and siltation of waterways. Since there is no environmental data for the area, the following research aimed to develop an environmental diagnosis of the physical env

9. Regionalização de potencial hidrelétrico com escassez de dados : aplicação Moçambique
Hydroelectricity (hydropower) is one branch of water resources engineering, which uses water (river flows) producing electricity. A hydroelectric undertaking, besides providing electricity and its comfort, it also allows the establishment of other productive activities, which provides a good economic and social development of the population (social responsab

10. Técnicas de sensoriamento remoto e geoprocessamento aplicadas ao planejamento territorial do Município de Cantá, Estado de Roraima
In the municipality of Cantá, in Roraima State, as well as in the Amazônia, land use activities have been practiced (by loggers, cattle raisers and agriculturers) in an extensive and predatory way, causing, many times, the degradation of the environment. Using Remote Sensing and Geoprocessing techniques this work contributes to land use management of munic
