Capacidade de Uso das Terras da Bacia do Ribeirão Água Fria – Bofete (SP)

A determinação da capacidade de uso das terras numa bacia é muito importante para o planejamento e uso do solo, pois o uso inadequado e sem planejamento dessas terras provocam a baixa produtividade das culturas. Este trabalho visou definir as classes homogêneas de capacidade de uso da terra da bacia do Ribeirão Água Fria - Bofete (SP) para atender ao planejamento de práticas de conservação do solo desta área. A bacia situa-se entre as coordenadas geográficas 22o 58' 30`` a 23o 04' 30`` de latitude S e 48o 09' 30`` a 48o 18' 30`` de longitude W Gr., apresentando uma área de 9.180,12 hectares. A carta de capacidade de uso da terra da bacia foi elaborada a partir da carta clinográfica obtida por Santos et al. (1999), mapa pedológico do Estado de São Paulo (Oliveira et al., 1999), da tabela de julgamento de classes de capacidade de uso do solo (França, 1963) e das recomendações constantes no manual para levantamento utilitário do meio físico e classificação das terras no sistema de capacidade de uso (Lepsch et al., 1983). A discriminação, o mapeamento e a quantificação das áreas das classes e subclasses de capacidade de uso pelo Sistema de Informação Geográfica - IDRISI apresentaram os seguintes valores: IIIe,s - 517,020 ha (5,63%); IIIs - 863,150 ha (9,40%); IVe - 846,730 ha (9,23%); VIe - 871,110 ha (9,49%) e VIIe - 6082,115 ha (66,25%). Os resultados permitiram concluir que a bacia essencialmente constituída por 2/3 pela subclasse VIIe, ou seja, são terras que podem ser utilizadas por pastagens com uso moderado ou florestas, pois apresentam problemas complexos de erosão por causa de sua declividade. O Sistema de Informação Geográfica IDRISI permitiu através de seus módulos discriminar, mapear e quantificar as áreas das classes e subclasses de capacidade de uso das terras da bacia com rapidez e confiabilidade.

Avaliação das taxas de erosão química da bacia hidrográfica do Ribeirão Monjolo Grande, Ipeúna (SP)

The development of human societies and their activities generate many impacts on the environment and natural resources. The consequence of these problems is a disturbance of the systemic dynamics of Planet Earth. Study these impacts are a way to understand the workings of this system and undertake efforts to prevent minimize and anticipate scenarios caused by environmental impacts. In this sense, from a systemic approach seeks to understand the way how is the interaction of the components of the ecosystems, adopting for this task the hydrographic basin as a natural unit of planning and management in view of the fact all landscape elements (atmosphere, hydrosphere, biosphere and geosphere) interact so that the reflections of human activities can be represented in this unit. Thus, this study aims to quantify chemical erosion rates in the hydrographic basin of Ribeirao Monjolo Grande, Ipeúna (SP), which is relevant to analyze the geomorphological characteristics of the area, which may serve to better exploitation of natural resources

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...

Elaboração de mapa de susceptibilidade de corridas de massa/detritos e ondas de cheia, aplicado a empreendimentos dutoviários, na bacia hidrográfica do Ribeirão da Prata (SP)

Given the intense expansion of the industries in Brazil and the discovery of hydrocarbons in the pre-salt layer of the Santos and Campos Basin, there is a need to expand the distribution of oil and gas network in the country. The present work aims to present the development of susceptibility map by two distinct methods of two events (debris flows and full wave), applied to the establishment of pipelines on Ribeirão da Prata Basin. The research area covers two municipalities: São João da Boa Vista and Águas da Prata, in total 145 km2. In the paper was used the methodology proposed by Zaine (2011) for the physiographic subdivision method, which uses geological maps, geomorphological maps, digital terrain models and aerial photographs, used to extract the main elements of the physical environment, as rivers, lines, ridges, tops forms and valley forms and historical processes. Thus, the basin was divided into 11 physiographic zones, considering the following elements: thickness of soil, rock type, geomorphology, amplitude, ridges orientation, erosion occurences and mass movements. Were subsequently performed location maps of dams, that had as main purpose to localize major dams in the study area along with their area and perimeter of the reservoir, and land use map that subdivided the area in woody vegetation, permanent culture, temporary culture and urban area. Along with the preparation of the auxiliar maps was conducted a field campaign with three days and approximately 2 points per km2, which aimed to better understand the physical environment and check the main peculiarities of the study area. Criteria have been established for susceptibility maps physiographic subdivision and land use, and a survey of criteria weights used in each map for both processes under study. For the preparation of susceptibility maps were adopted two different methods, which treat the weighted average and the multiplicand. The weighted average method it is...

População e áreas de risco: o caso das inundações na área central de São José do Rio Preto-SP

The problem of flooding in urban areas exist in many cities and their causes are as varied as the areas of occupancy or Valley weatherproofing Fund areas of infiltration in the drainage basin. The anthropic activity come triggering changes and impacts on the environment for a long time, and there is a growing need to come up with solutions and strategies that minimize and reverse the effects caused these risk areas. Thus, the present work will address the case study in São José do Rio Preto-SP that is an exception, since the area that is considered of risk lies in the Centre, unlike most lying on the outskirts. This will also analyze the processes of urban expansion and the situations of social and environmental vulnerability, including their interrelations in urban scale. The physical study of the area will serve as an important basis for the work, but it will focus mainly on the population and the problems which this is being in hazardous areas. We will not join a single methodology, wharever, we will follow our knowledge to adapt what we feel that fits better, every time. The importance of this study is that in addition to identifying the problems which the local population suffers with floods, lists measures that minimize the environmental impacts arising through the fostering of public policies

Contribuição das águas subterrâneas para a vazão do Ribeirão Boa Vista ou Córrego do Lajeado

This paper aimed to give a contribution to improve water resources management, consists of the analysis of interaction among groundwater and streamflow, by through the analysis of the relationship between basic and total streamflow, based on measured hidrological data from Ribeirão Boa Vista or Córrego Lajeado. watershed. Comparisons among groundwaterflow in this basin with another one in Rio Corumbataí basin were made based on the specific basic flow, in order to verify the possibility of the utilization of measured hydrological data in other basins with similar geological characteristics and soil use and occupation. Based upon the comparisons that were made, specific basic flow does not represent a good tool for extrapolation of measured data, indicating that this comparison shall be weighted by others characteristics as permeability and thickness of geological formations. Finally, it was possible to conclude that basic flow may be considered as an additional parameter for analysis of hydrological and hydrogeological characteristics of a basin and to provide subsidies to release legal licenses for water resources uses. related to surface water as well as for groundwater and may also be used as a tool for consolidation of integrated management of water resources, that is considered as a necessary and essential practice to avoid conflicts between users of water resources in a river basin.

O estilo de João Ubaldo Ribeiro em Viva o Povo Brasileiros e An Invincible Memory

This paper aims at observing a particular case of an author’s and self-translator’s style in the pair of works Viva o Povo Brasileiro and An Invincible Memory. Our investigation has its theoretical starting point based on Corpus-Based Translation Studies (Baker, 1993, 1995, 1996, 2000; Camargo, 2005, 2007), and works on cultural domains (Nida, 1945; Aubert, 1981, 2006). The results showed that great part of cultural marks may be classified as the material, social, and ideological cultural domains, which reflects the context of the source text. It was also possible to observe that normalization features tends to reveal conscious or unconscious use of fluency strategies by the self-translator, making the translated text easier to read.
