ANÁLISE NEOTECTÔNICA DO PONTAL DO PARANAPANEMA (SP) MEDIANTE APLICAÇÃO DE PARÂMETROS FLUVIOMORFOMÉTRICOS

Mediante a aplicação de técnicas de análise flúviomorfométricas disponíveis na literatura especializada, tais como estudo dos perfis longitudinais dos cursos d’água e os índices RDE (Relação Declividade vs. Extensão), buscou-se, neste trabalho, executar uma análise de prováveis deformações neotectônicas na região do Pontal do Paranapanema, extremo oeste do Estado de São Paulo. Dessa forma, a análise dos parâmetros flúvio-mofométricos proposta foi aplicada nas bacias hidrográficas menores que drenam tanto para o rio Paranapanema, ao sul, quanto para o rio Paraná, a oeste. As medidas foram efetuadas, inicialmente, nas drenagens com extensão superior a 8 km, tendo como base topográfica as folhas plani-altimétricas em escala 1:50.000, com equidistância de 20 m, editadas pelo IBGE e pelo IGC, totalizando 22 cartas topográficas. Os dados coletados foram lançados em planilhas Excel para a obtenção dos resultados gráficos e definição das anomalias. Utilizou-se de base geológica em escala 1:500.000 editada pelo IPT (1981), para comparação dos dados fluviomorfométricos com o substrato geológico sulcado pelos cursos d’água. Os trabalhos finais envolveram o cotejamento de todas as informações flúvio-morfométricas e geológicas e a interpretação das anomalias delimitadas. Para tanto se fez necessário elaborar uma base morfoestrutural adequada, que se baseou na análise de imagens de satélite do sistema SRTM, da NASA, com o auxilio do aplicativo Global Mapper. Os dados de morfometria fluvial indicaram a presença de um significativo número de anomalias, com destaque para trechos subsidentes de cursos d’água e também para perfis longitudinais retilíneos de drenagem, que se destacam do padrão logarítmico típico dos rios. Tais trechos foram interpretados como tectonicamente desequilibrados, indicando deformações crustais recentes. As anomalias flúviomorfométricas foram comparadas com áreas de solos espessos, interpretadas em imagens SRTM, e com a trama de lineamentos, confirmando que as áreas mais dissecadas correspondem a trechos com movimentação ascencional, que resulta em solos rasos e presença de anomalias de RDE. Os terrenos com solos mais espessos, por outro lado, abrangem áreas em subsidência, que podem incluir depósitos aluviais mais expressivos. Não-raro, estas áreas são demarcadas por limites estruturais (lineamentos) e/ou por trechos de perfis longitudinais anômalos de drenagens.

Geotecnologias para análise da expansão urbana e consequências na APP do Córrego Olinda - Rio Claro/SP

Despite the current Environmental Legislation resolution, concerning the protection of the Permanent Preservation Areas (PPA), be quite rigid, in practice, is observed noncompliance with the minimum limits of protection, especially in urban areas where, historically, the urbanization processes have been executed without compliance with the minimum standards of urban and environmental planning. Given the above, the present study aimed to analyze the urban sprawl evolution at the Olinda stream APP, located in the city of Rio Claro - SP. By means of the visual interpretation of aerial photographs in the GIS/ARCGIS environment, thematic maps of the urban sprawl of the years 1972, 1995 and 2010, as well as the Olinda Stream APP surroundings, were prepared. From the maps, it was possible to measure the occupation density for each scenario and indicate from which period the urbanization process has intensified. It was also possible to quantify the loss of vegetation area and indicate the major environmental problems in the basin of the Olinda stream. Therefore, the development of this research shows its importance, considering that its results can support the public administration, assisting in proper planning of land use and occupation in urban watersheds

Diagnóstico antropogeomorfológico em bacia hidrográfica urbana: o caso do Córrego do Jardim São João, Araras (SP)

Man can transform the nature according to their needs through technique which enables agriculture, cattle raising, constructions of buildings for housing, transport routes, etc. This action has brought significant transformations to the environment, and relief is one of the most changed elements, mainly at urban areas, which concentrates most of the Brazilian population. In these areas geomorphologic systems have undergone alterations in their flow of matter and energy by the action of man. Thus, it is possible o understand the action of man as geomorphologic action, nowadays, the tecnógeno, since the human action can interfere qualitatively and quantitatively in the input and output of these systems. The anthropic geomorphology has contributed to the analyses of the effects due to the urbanization at the form and at the geomorphologic process in the urban watersheds, indicating the transformations at the shape of the relief and the alterations due to the acceleration of the flow of matter and energy. From these questions, this study had the main diagnose the anthropogenic changes of the relief at the basin of Corrego do Jardim São João, Araras (SP), comparing two scenes, 1997 and 2006, through geomorphological mapping evolutionary in the area. The geomorphological feature altered at the basin are directly linked to the use of soil, mainly at the urban use, which caused effects in the relief at the studied area, making possible to define periods of the urban evolution and impacts caused by the urbanization. Among the changes it was found the decrease of the topographic breaks and at the riverbed channels, as the increase of the accumulation of the plain and riverbed terrace. The elaboration of a letter of the legal restrictions of the basin make possible to evaluate some of the environmental urban problems that occur, which are due to the occupation of the relief in the areas of permanent preservation that brings significant impacts to...

Uso do modelo de simulação 'ABC 6' para avaliação de áreas sujeitas à ocorrência de ondas de cheia e corridas de massa/detritos: estudo de caso na bacia do Ribeirão da Prata (SP)

Pipelines are linear engineering works, designed mostly for transporting oil and its derivatives for long distances, furnishing even the farthermost zones of the country. Due to oil sector needs to ensure for the safety and conservation of its properties, several geotechnical studies are being held at the pipelines field, in order to preserve this important transportation, and also to prevent accidents, which might seriously compromise the environment and the population who lives around it. The OSBRA pipeline, who connects the city of Paulínia to the capital Brasília, is one of these engineering works that deserves to be pointed out. This research, performed at the Ribeirão da Prata Basin, was a pilot study conducted with the main objective of testing the current methodology efficiency, for future applications in the closest watersheds to the OSBRA pipeline. The objective of this research is to analyze flood wave and debris flow processes in a non-fictional watershed, by comparing two different kinds of methods: the first one based on simulation models (software ‘ABC 6’), and the other one by flood wave and debris flow susceptibility mapping. The results from the hydrological modeling were both hydrographs and ietographs that estimated values of outputs and infiltration. To construct the susceptibility maps were necessary three other maps: ground use and occupation maps, divided according to the different protection degrees that were offered to the ground; maps of dam locations in the area and physiographic compartimentation maps, divided according to the local geology. To complete the methodology, the results were collected from both methods for comparison. The obtained product for this methodology was series of data whose different susceptibility degrees to flood wave and debris flow could define the safest route for a pipeline crossing in this watershed...

Geotecnologias para a análise da bacia hidrográfica do Córrego Wenzel - Rio Claro/SP: proposta de gestão de recursos hídricos

The expansion of urban in medium-sized citie, increase the importance of action planning and management of natural resources, among which water is the most important. Such action should include the integration of physical and man-made elements involved. In this context, it becomesimportant for watershed analysis and the use of geotecnologies. Thus, the objective was to demonstrate the contribution of the geo, as a tool for managing a river basin, allowing the integration of physical data and the analysis of anthropogenic environmental scenarios in urban areas. The area chosen, the basin of the Wenzel, is located in Rio Claro / SP, a city whose urbanization process has been intense and continuous. Thematic maps were generated from the physical environment: soil, slope and geological, as well as maps of land use. With regard to land use maps, these were drawn from the visual interpretation of material aerophotogrammetric, considering the years 1995 and 2010, performing an evolutionary analysis. It was observed that the area presents small variation in the physical and structural aspects, with lithological and geomorphological formation favoring the occurrence of floods, erosion and siltation. These processes are accelerated by the forms of land use, with intense urbanization during the period between 1995 and 2010, and poor preservation of permanent preservation areasand. In the floodplain areas there is a high waste disposal is the most notable environmental problem
