13. MAINTENANCY PHYSICAL DIAGNOSIS AND ITS RELATION TO SEDIMENTATION AND LANDSCAPE PREFERENCES / DIAGNÓSTICO FÍSICO CONSERVACIONISTA E SUA RELAÇÃO COM A SEDIMENTAÇÃO E PREFERÊNCIAS DA PAISAGEM
The use and occupation of land have been occurred in an inadequated form many times in watersheds. Deforestations, farmings and fields planted in inadequate areas, in absence of Maintenancy treatments and urbanization without planning had been considered serious problems that generate ambient conflicts. These take to the environmental deterioration, soil ero

14. A ocupação da Bacia do Rio das Velhas relacionada aos tipos de solo e processos erosivos
With the intention of avoiding the occurrence of erosive processes and the environmental damages that these cause to the hydrographic basin, it is important to know the influence that the soil characteristics, together with the way in which it is occupied, can have on environmental degradation. With this in mind, this study attempted to establish the relatio

15. Seleção de espaços rurais para o desenvolvimento do agroturismo sob a perspectiva da conservação ambiental : uma proposta metodologica
The agro-tourism is growing in Brazil as an alternative means to promote the agricultural development, to increase the income of small rural producers and, at the same time, to stimulate the preservation of natural resources, the cultural aspects and the agricultural landscape. However, its planning is still incipient, realized mostly by the property owners

16. Environmental diagnostic and temporal analysis of the suitability of the land use and land cover in the Ribeirão dos Marins basin, Piracicaba - SP / Diagnóstico ambiental e análise temporal da adequabilidade do uso e cobertura do solo na bacia do Ribeirão dos Marins, Piracicaba - SP
The environmental diagnostic and the analysis of the occupation suitability allows the identification of more critical areas according to its degradation level, being extremely important for the establishment of preservation, conservation and recovery measures. An environmental diagnostic and suitability analysis of the land use and land cover of the Ribei

17. Zoneamento geoambiental com auxílio de lógica fuzzy e proposta de um geoindicador para caracterização do meio físico da Bacia do Rio do Peixe / Geoenvironmental zoning using fuzzy logic and proposal of a geoindicador to characterize Rio do Peixe basin environment
This study presents a methodological technique to characterize environmental restrictions and aptitudes considering continuous variation in the attributes and gradation in contato between units. Fuzzy logic procedures were used to generate representation of contact gradation for rocky substratum and unconsolidated materials maps. Continuous attribute variati

18. Modelagem de parÃmetros biofÃsicos para avaliaÃÃo de risco à desertificaÃÃo
A integraÃÃo de aÃÃes sustentÃveis conciliando programas sociais, ambientais e econÃmicos sÃo de vital importÃncia em Ãreas com risco à desertificaÃÃo. Esta pesquisa mostra a aplicaÃÃo de parÃmetros biofÃsicos e potencial de erosÃo na avaliaÃÃo de processos degradatÃrios e identificaÃÃo destas Ãreas de risco. à uma abordagem geral e p

19. Solos do Projeto Xingó: caracterização e limitações ao uso com agricultura irrigada / Soil of the Xingó Project: characterization and limitations to irrigated land use
Soil research aiming irrigated land use have great importance in the semiarid Sertão zone of Sergipe state. With this purpose, four soil profiles were characterized and classified along a topossequence, including two Regolithic Nesols, a Planosol and a Luvisol. The objectives were to evaluate soil potential for irrigated land use and to produce information

20. ESTIMATIVA DO ESCOAMENTO SUPERFICIAL A PARTIR DE TESTES DE INFILTRAÃÃO NA BACIA HIDROGRÃFICA DO RIBEIRÃO ITAIM
The Itaim Watershed lacks planning for land use, reflecting typical conditions frequently seen in the area of the valley of ParaÃba. This has been causing increase of runoff, increase in soil erosion, sedimentation of the water channels, inundations and floods in those watersheds that form the ParaÃba do Sul Basin. This study carried out in the Itaim water

21. Riscos e gestÃo ambiental no estuÃrio do Rio malcozinhado, Cascavel-CE
The Rio Malcozinhado lagoon-estuarine system is located in the Cascavel municipality, in the Cearà State Southeastern littoral 75km away from Fortaleza, Northeastern Brazil. Its 380 km2 hydrographic basin lies on basement rocks, Plio- Pleistocene Barreiras Formation sediments and Quaternary deposits. The urban expansion of the area in the last two decades w

22. STABILITY ANALYSIS OF SOIL SLOPES UNDERMINED BY VOÇOROCAS / ANÁLISE DA ESTABILIDADE DE TALUDES SOLAPADOS POR VOÇOROCAMENTO
In this work the finite element method is employed to analyze the stability of soil slopes undermined by voçorocas (gulling). Many of the shear slides occurred in both natural slopes and embankments have been caused by the phenomenon of voçorocas, the outcome of a very complex soil erosion mechanism. A brief review about the formation and growing of voçor

23. Caracterização fisica dos solos de uma microbacia degradada em Vera Cruz, SP
The knowledgement of soil physical properties in a catchment basin, in special at places which show signs of erosion and degradation, represent the flfst step for a successful conservation planning as well as to provide additional information for the application of mathematical models that determine the soil erosion potential. This study was carried out to c

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
