Avaliação das taxas de erosão química e física na bacia hidrográfica do Ribeirão Jacutinga (SP)

Currently with the growing technological advancement and global, new areas are being devastated, and as a result, the erosion became more frequent causing loss of soil, infiltration capacity of the surface and weathering of rocks. In this way, environmental studies are increasingly frequent to understand the environment in which we live, but also to avoid any degradation of the same and of finite natural resources, which are essential for human life. From this, this work has as main goal, analyzing the rates of chemical and mechanical erosive watershed of Ribeirão Jacutinga, at its mouth, in the city of Rio Claro, supporting environmental studies and sustainable development today. Order to reach these values were measured and total dissolved solids in suspension in the stream during the months from January to July 2012. As results included higher rates of both physical and chemical weathering in the rainy months, especially january

Diagnóstico ambiental das áreas de expansão urbana do município de Jaguariúna - SP

The spatial chaotic urban growth is an increasing and common problem in Brazilian cities, especially in the State of São Paulo. In order to assist the territorial expansion planning, the present study aimed to conduct the environmental diagnosis of urban expansion areas in the City of Jaguariúna – SP, bounded by the Municipal Plan. From the preparation and analysis of thematic maps, literature review and field analysis, data were collected for use and occupation, geology, geomorphology, pedology, vegetation, water resources and features surrounding the five urban sprawl existing areas. It was noted, in general, that these areas are suitable for urban occupation, since they show flat geomorphology characteristics, with flattened, medium to large hills, slightly undulated, with low slope, and soils that do not present risks to the deployment of buildings, once properly managed. It was also observed a few water bodies crossing these areas and a few areas with native vegetation beyond permanent protection areas along the rivers. By the analysis of these areas and their surroundings, it was possible to determine on which area the urbanization process can occur more quickly. Thus, the study allows the City of Jaguariúna to perform a more effective occupation planning in these areas, always aiming the sustainable development and, consequently, the improvement in population’s quality of life, as well as the maintenance of environmental quality.

Análise geomorfológica e de impactos ambientais da microbacia do Córrego Wenzel - Rio Claro/SP

This study aimed to survey and analyze the geomorphological aspects of watershed stream Wenzel in Rio Claro, as well as anthropogenic incidents about which he eventually causing serious environmental impacts. All these changes in the natural environment are generated from the constant development of the urban environment, which ends up leaving aside factors relevant to the natural order and that over time they become problems to humans. As various forms of environmental degradation occurring on some form of relief, geomorphology can make a major contribution in this field, since the analysis of the hydrographic network can lead to understanding and explanation of numerous geomorphological issues because the waterways are process morphogenetic the most active in the terrestrial landscape sculpture. The research with a systems approach and vision interrelated aspects in question may even serve as a basis for practical planning and urban management, in addition to detailed study of the area, which is of paramount importance to the local society

Proposta de recuperação e manejo de nascente em área rural do município de Álvares Machado – SP

The lack of proper planning in intervention works of runoff water on rural properties and rural public roads leads to economic damage and loss of environmental quality. The impact of the action without technical base is soil erosion, siltation of water sources, loss of the quality and availability of water, invalidating areas for cultivation and livestock. The conservation of headwaters requires beyond regeneration of the environmental characteristics the repair and management of the degraded watercourse in order to control erosion. This graduate work in Environmental Engineering from Universidade Estadual Paulista Julio de Mesquita Filho - UNESP Presidente Prudente proposes a headwater recuperation and management in rural area of Álvares Machado municipality, São Paulo State, through the method of deep drainage applied to the case of a rural road near the outcrop of water. This technique consists in the installation of draining structures in sub-areas of the road surface, or sub-gutter and/or in the platform border in order to conduct the underground flow of water and reduce the loss of sediment in water flow. Therefore, was performed a historic study of use and occupation of land in the municipality of Álvares Machado, portraying transformations of the landscape caused by human action. Geology, geomorphology, pedology and hydrogeology data were collected from the study area in order to establish the conditions that led into the current situation of degradation and formulate an effective intervention strategy for civil works

A antropogeomorfologia na bacia do Córrego do Cavalheiro - Analândia/SP: uma avaliação da dinâmica do uso da terra e sua adequabilidade a legislação ambiental e a capacidade de uso

The assessment of land use dynamic can be an instrument for analysis in anthropogeomorphology, which would allow one to verify the human geomorphological actions and its various implications in changing the original morphology for the creation of a human morphology. This study aimed to consider the land use dynamics and its interference in the morphology of Cavalheiro Stream Basin. From this assessment, to understand the implications of land use in the creation of a human morphology, as well as to analyze if the current use is in accordance with the legal restrictions placed by ongoing environmental legislation and with the ability to land use. The chosen of this studied area was due to assumptions raised by Pinton (2007) for changes in the dynamic of rainwater erosion of this area caused by human actions, specially the cultivation of sugar cane in morphologies that are unfit for it. The search took as methodological support the principles that concern the General Systems Theory, trying to see the watershed as an open system. The geomorphological data, of land use and of legal restrictions to the use and occupation of land, were collected from different cartographic techniques. Besides, it was developed a sketch map of land use capacity by adapting the technique proposed by Lepsch (1983). This way, the data obtained in this survey are considered capable to provide subsidies for the identification of changes in original morphology of the Cavalheiro Stream Basin and the genesis of a human morphology, as well as conflicts and adjustments of current land use in environmental system and on the legal restrictions outlined in the ongoing environmental legislation, contributing to a proper environmental planning with the characteristics of the physical environmental system of this basin

Análise geomorfológica e do uso da terra da bacia do Ribeirão Tijuco Preto (SP): subsídio ao planejamento ambiental

Este trabalho teve como objetivo principal analisar a dinâmica geomorfológica, bem como a apropriação humana do relevo, mediante a interpretação de forma integrada dos documentos cartográficos elaborados a partir de técnicas da cartografia morfométrica, geomorfológica e de uso da terra, de forma a subsidiar ações vinculadas ao planejamento ambiental da Bacia do Ribeirão Tijuco Preto (SP). Sob os auspícios da abordagem sistêmica, a partir de uma visão integrada e complexa dos sistemas geomorfológicos, propôs-se a quantificar os atributos das formas de relevo, representando-os cartográficamente com a elaboração das Cartas Morfométricas de Declividade ou Clinográfica (De Biase, 1970 e 1992), de Dissecação Horizontal (Spiridonov, 1981 e adaptações de Mauro et. al.,1991), de Dissecação Vertical (Spiridonov, 1981) e de Energia do Relevo (Mendes, 1993). Também, contemplou-se a cartografia geomorfológica de detalhe, com a elaboração da Carta Geomorfológica (Tricart, 1965), bem como o mapeamento do uso da terra, expresso na Carta de Uso da Terra (Ceron e Diniz, 1966). De forma geral, a análise dos Produtos Cartográficos elaborados, permitiu constatar que a Bacia do Ribeirão Tijuco Preto vem sofrendo o desencadeamento de processos erosivos variados. Tais processos estão associados a uma conjunção de condicionantes, que podem ser apontados pelas variadas condições morfométricas do terreno, o clima quente e úmido reinante, as diferentes litologias aflorantes, a tipologia dos solos, bem como, e, de maneira veemente, a intervenção humana. O condicionante antrópico está majoritariamente representado pela monocultura canavieira e pela urbanização, sendo agentes cruciais no desencadeamento dos processos erosivos existentes e na interferência direta na dinâmica do escoamento fluvial da Bacia do Ribeirão Tijuco Preto.

Mapeamento dos compartimentos de relevo do município de Estrela do Norte-SP e adjacências

The Geomorphology is to study the relevant object, which is the substrate where there are social relations, where society draws the natural resources for their survival and structure its immediate surroundings. In this context, the geomorphological map is currently considered as an important tool in landscape research. The landscapes of the city of Estrela do Norte-SP and surroundings consist mostly of geological substratum of sedimentary rock formations of Adamantina and Santo Anastácio (IPT, 1981a). Geomorphologically dominated by large reliefs of gently rolling hills tops and pedologicamente, the Oxisols and Ultisols Red-Yellow (Oliveira et al., 1999), which historically without proper management, formed a serious degradation of erosive framework in the study area. Thus, this study aimed to produce a map of the major compartments of the municipality Estrela do Norte-SP and surrounding areas, using techniques of digital stereoscopy. In relation to the procedures used in developing the mapping of geomorphological compartments, the main references were Tricart (1965) and Ross (1992). To prepare the mapping applied to refund technique - 3D through the ALOS / PRISM images...
