25. 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

27. Environmental impacts from soil burning in Miranda District, Municipality of Parambu - Cearà / Impactos ambientais causados pelas queimadas nos solos do Distrito de Miranda no MunicÃpio de Parambu - CearÃ
We evaluated the environmental impacts caused by the fires in soils of the District of Miranda in the Municipal district of Parambu, Cearà State through the analysis of the environmental physical-chemical parameters of the soils, the texture analysis, and the use of plots having collectors to store the soil transported by the rains and the determination of

28. Estudo geolÃgico â geotÃcnico do processo erosivo em encostas no parque metropolitano armando de holanda cavalcanti - Cabo de Santo Agostinho/PE
Water erosion for if dealing with to a so vast and complex subject and as many implications need to be monitored, to be analyzed and to be understood in some scales. The inquiry campaigns must be based mainly on the involved mechanisms in the process. It is necessary to have relative information of the way, in what it says respect to the possibility of diffe

29. Definição de áreas prioritárias para conservação e preservação florestal por meio da abordagem multicriterial em ambiente SIG. / Definition of priority areas for forest conservation and preservation using multicriterial evaluation with GIS.
The forest fragmentation of the Corumbataí River Basin, SP (Brazil) is a consequence an unplanned process of soil occupation and use. The purpose of this study was to define priority areas for forest conservation and preservation in that river basin, aiming at improve the regional biodiversity. Multicriteria evaluation with Ordered Weighted Average was used

30. Evaluation of soil erodibility index using the 137Cs fallout redistribution analysis / "Avaliação de índices de erodibilidade do solo através da técnica da análise da redistribuição do "fallout" do 137Cs"
Entre os parâmetros da USLE (Universal Soil Loss Equation), método mais utilizado na estimativa das perdas de solo por erosão hídrica, a erodibilidade do solo, representada pelo fator K e definida como a taxa de solo perdida por unidade de índice de erosividade, em parcela unitária considerada como padrão (Wischmeier et al., 1971), é o único intrín

31. THE GULLY PROCESS STUDY NEXT TO THE ITUMBIARA HYDROELECTRIC COMPLEX - GO / ESTUDO DE UM PROCESSO DE VOÇOROCAMENTO PRÓXIMO A UHE DE ITUMBIARA - GO
This dissertation, developed within the context of the PRONEX Project of the Environmental Geotechnical Center of PUC-Rio and through a FURNAS-PUC-Rio Convenium, presents a contribution towards the identification and comprehension of mechanisms involved in erosion processes, considering its geological and geotechnical aspects as well as preventive repairing

32. Geotechnical mapping and analysis of erosion process at Tuncum creek watershed, São Pedro-SP, scale: 1:10.000 / Mapeamento geotécnico e análise dos processos erosivos na bacia do córrego Tuncum, São Pedro-SP, escala 1:10.000
This work aims to analyze the main factors related to the erosion processes in the Tuncum creek watershed, city of São Pedro-SP, based on the observed geological-geotechnical characteristics in the field and laboratory (soil geotechnical characterization and erodibility tests). It was verified that high susceptibility area to the erosion processes are mainl

33. Elaboração de carta de susceptibilidade à erosão das bacias dos rios Araraquara e Cubatão-SP, escala 1:50.000 / Elaboration of the erosion susceptibility map of the Araraquara and Cubatão river basins - SP, scale 1:50.000
In this present work many environmental attributes were identified, in order to create a soil erosion susceptibility chart (1:50.000 scale) for the Cubatão and Araraquara hydrographic basin, which in turn, are part of the greater Pardo river basin. These attributes were bedrock classification, unconsolidated materials, slope and land use. The soil erosion s

34. Carta de vulnerabilidade a erosao como subsidio ao zoneamento ecologico-economico em area intensamente antropizada / x
he objective of this study is to prepare a map of vulnerability of soil erosion of an occupied section of the medium Rio Paraiba do Sul watershed surrounding the city of Sao Jose dos Campos, Sao Paulo State. The methodology used was adapted from that proposed by Crepani et al. (1996)to subsidy the Ecologic Economic Zoning from Amazonia. The theoretical backg

35. 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
