13. Physiographic characterization of the Antas River hydrographic basin, Poços de Caldas Plateau, MG / Caracterização fisiografica e avaliação hidrologica na bacia do Ribeirão das Antas, Planalto de Poços de Caldas, MG
The objective of this paper is to determine some physiographical parameters regarding the Antas River Basin, Poços de Caldas Plateau, presenting one set technical information essential to the water resources management. Hydrographic basin dimensional values are quantitative parameters that allow the elimination of certain subjectivity from basin characteriz

14. AvaliaÃÃo da retenÃÃo de gases em camadas de cobertura de aterros de resÃduos sÃlidos
Municipal solid waste landfills final covers work as a seal interface between the wastese and the external environment. This sealing layer is also responsible to avoid the infiltration of water into the waste mass and the emission of gases to the atmosphere. These interventions show by they own how important are both project and execution of the top cover as

15. Modelagem dinâmica de perdas de solo : o caso do alto curso da bacia hidrográfica do Rio Descoberto-DF/GO
Este trabalho propõe-se a contribuir com uma estimativa multitemporal de perdas de solo por erosão laminar que represente de forma mais real o caminho seguido pelo fluxo dágua e de sedimentos e sua acumulação, empregando modelagem dinâmica. Além disso, os resultados desta pesquisa têm o intuito de colaborar com o planejamento ordenado de uma área em

16. Avaliação de diferentes topografias residuais na distribuição de tensões no remanescente dental por meio da análise de elementos finitos / Different residual topographic analysis in the distribution of tensions in the residual teeth by means of the finite element analysis
The presence of dentin projection above the finish line in the preparation of endodonticaly treated tooth to receive post and core is well established in literature, it influences positively in the resistance of the root. However, due to dental destruction, its not always possible to achieve a homogenous projection design, contributing for deficiencies in th

18. Geoambientes, pedogênese e uso da terra no setor norte do Parque Nacional da Serra do Divisor, Acre / Geo-environments, pedogenesis and land use in north sector of the National Park of Serra do Divisor
The Serra do Divisor National Park , in the Upper Jurua River, west of the State of Acre, with 784.077 hectares, is covered by primary forest vegetation, with high biodiversity. In this study, we caracterized and mapped the geoenvironmental units and the land use of the northern sector of the Park (319.373 ha), and we also studied the pedogenetics aspects of

19. Aplicação de dados SRTM à modelagem da erosão em microbacias por geoprocessamento / Application of SRTM data to the modelling of erosion in watersheds using geoprocessing
The Universal Soil-Loss Equation (USLE) is a widely used method for calculating annual soil erosion losses, based on rainfall, soil type, topographic and land-use parameters. This study was designed to apply SRTM data for erosion modeling through USLE. The analysis of two watersheds in Maranhão showed the feasibility of remote sensing applications beyond la

21. Experimental investigation of turbulent boundary layers over steep two-dimensional elevations
This work presents a laboratory study on the behavior of turbulent boundary layers over steep topographic elevations. Two main topics of interest are addressed here: (i) to investigate and characterize the separated flow region that is formed on the leeside of a steep elevation, and (ii) to evaluate the effects of flow stability conditions on the properties

22. Models USLE and MUSLE aplication in Ribeirão Bonito - SP watershed through remote sensing and geoprocessing / Aplicação dos modelos EUPS e MEUPS na Bacia do Ribeirão Bonito (SP) através de técnicas de sensoriamento remoto e geoprocessamento
Remote sensing and geoprocessing techniques were used in running two soil erosion predictive models (USLE Wischmeier and Smith, 1978 and MUSLE - Williams, 1975). The research area in the surroundings of Barra Bonita, Santa Maria da Serra, SP. Several input parameters were integrated in a Geographic Information Systems (GIS, SIG/INPE) according to each model

23. Methods for evaluation of L and S factor for the universal soil loss equation (USCLE) in a watershed, involving geoprocessing and database. / Avaliação de métodos para obtenção dos fatores "L" e "S" da EUPS numa microbacia, via geoprocessamento e banco de dados.
This work deals with remote sensing, GIS, and database. The test site is the Ribeirão das Araras watershed, located in Araras, SP, Brazil. The Universal Soil Loss Equation (USLE) was modeled, with emphasis on the topographic factor, which is divided in slope lenght (L ) and slope (S ). Both were calculated by two different methos: L1 or method of the prefer

24. Análise da erosão do solo usando a EUPS, através de técnicas de sensoriamento remoto e geoprocessamento / Soil erosion analysis, using the USLE, using both remote sensing and geoprocessing techniques
The Universal Soil Loss Equation (USLE) has been used within geographical information systems targeting the development of means of producing basic planning information. Remote sensing data have been used to map the most dynamic side of erosion: land use and management. Overestimations of erosion and Natural Erosion Potential have been regularly obtained, th
