The inadequate disposal of municipal waste is one of the biggest environmental problems. The lack of long public politics makes this problem a challenge to their administrators. Finding a place for the disposal of waste is an easy task and the present work looks forward to a better understanding about the concepts involved in order to choose favorable areas for the development of sanitary landfills, minimizing environmental impacts. In this line of thought several areas in Rio Claro`s region were evaluated according to the environmental terms. The areas which were classified as good or almost good will have a more elaborated study such as field works, evaluation and understanding of the concepts analyzed so that there aren’t any waste of money, work, social and environmental waste in the area. These areas were analyzed according to secondary data such as geological and pedological formation and primary studies such as the assumption of the reality as showed in the map will be made in order to acquire better results.

The crescent increasing demand of the electric power in Brazil has stimulated the implantation of Small Central Hydroelectric Power (SCHP) in several regions of the country. However, the silting up of the reservoirs is one of the main problems faced by hydroelectric power plants and SCHP. In this context, this research aimed evaluate the phenomenology and propose the enforcement of appropriate bioengineering techniques to control the intense erosive process of the hydrographical basin of the “Alto Rio Sucuriú,” that cause silting up of the reservoirs of the SCHP Costa Rica, located in the municipal district of Costa Rica (MS). In order to identify the phenomenology of the main falling in of this basin, a diagnosis of the conditions of the physical environment of the region (climate, geology, pedology, hydrology, and use of the ground) was realized. A surveying was also realized to specify the geometric feature of the falling in using the Total Station of the Ruide brand, series RTS 860R and the geodetic GPS of the Ashtech brand and the data obtained was used on the preparation of the Digital Elevation Model (DEM) of the falling in. Based on this diagnosis an official register of the falling in was done with identification of the different types of present erosion. Due to the advanced erosive stage of the falling in researched, the use of bioengineering techniques could be the best solution considering that the traditional engineering techniques make use of heavy material like concrete, iron and large machines that besides causing higher impact to the natural and esthetic aspects of the environment also require a higher investment of capital. This research establish a great cooperation to the knowledge of the erosive process and of the rehabilitation of the degraded areas with application of bioengineering techniques not only hydrographical basin of “Alto Rio Sucuriú” but also to other basins that show similar situation

As formigas da tribo Attini são especializadas na produção de fungos com os quais possuem uma relação de mutualismo, e para tanto, possuem várias estratégias de forrageamento de substrato de acordo com o gênero. Sabe-se que a atividade de forrageio é um comportamento social que varia sob influência de diversos fatores ambientais, tais como a estação do ano, temperatura, umidade relativa, estágio de desenvolvimento do ninho e período de reprodução. Neste contexto, ainda se conhece muito pouco sobre as técnicas utilizadas pelas formigas do gênero Trachymyrmex para busca de alimento. Por esta razão, o objetivo deste trabalho foi analisar a atividade de forrageio e coleta de substrato por colônias de Trachymyrmex tucumanus em áreas antropizadas, verificando o período do ano e do dia em que a atividade ocorre com maior intensidade, e quais as categorias de alimentos coletados por esse grupo de formigas. Durante o estudo, que transcorreu de dezembro de 2009 à setembro de 2010, foram acompanhados 10 ninhos, quatro por estação, sendo que alguns se repetiram em diferentes estações. No total foram feitos quatro dias de observações, um a cada três meses. Foi feita a contagem de operárias que entram no ninho a cada 2h por 20 minutos consecutivos com auxílio de um contador. Ao longo das observações foi possível identificar um padrão de atividade que se intensifica no final da tarde, quando a temperatura do solo é mais amena e a umidade do ar aumenta. Quando comparada a atividade de busca das operárias ao decorrer do ano constatou-se uma queda na atividade conforme se aproxima o período de seca. A maior atividade de forrageio se deu durante a primavera e o verão, que são estações mais chuvosas. Através da observação do material coletado pelas operárias foi possível identificar materiais vegetais, tais como, folhas secas, sementes, casca de frutas e algumas folhas verdes de gramíneas

Water is an essential element for life. The use of this element, to support the community, defines it as water resource. This feature is being misused and degraded by the dumping of highly contaminated effluents. The impoverishment of its quality poses a risk to human consumption. The necessity to manage this resource, treating the wastewater properly, requires the constant improvement of treatment systems. Another need is to adjust the cost of systems to the demands of communities with less financial clout. This study aimed to adapt and understand the systems of wetlands, improving its efficiency, in an attempt to collaborate with the enrichment of this technology. The practical evidence, with lab-scale prototypes, assembled in ETE Piracicamirim with urban sewage effluent contributed to highlight the problems and operating system design. The bibliographic review showed that several studies had effectiveness for treatment. But it was evident the need for better understanding of dimensioning definitions that better attempted to the answers into the project. Moreover, standardization of system conditions for the specific wastewater treatment is an interesting field, identified, for future studies yet contribute to environmental engineering and sanitation

The city of Guaratinguetá, SP, presents in its history, several instances of property damage and human losses, conditional on the event of flooding and mass movement of soil, resulting from the development of erosion processes. The extent and severity of these events that affect humans and their properties is the result of the illegal occupation of these areas as potential geohazard. Thus, it is of great importance to physical characterization and identification of such areas within the map of the same city as a way to minimize the effects and mitigate the consequences of these events. Thus, this graduate report presents a series of field campaigns, geotechnical laboratory testing, consultation with maps and satellite images, representative of the physical environment, and the city plan as a means conclusive for the delimitation of risk areas with potential for occurrence of erosion and / or flooding on the map representing the urban area of Guaratinguetá, SP. Also featured are the descriptions of the main characteristics of those areas identified as being at risk, along with proposals to avoid or minimize the impact of problems related to flooding and erosion processes on the local population

There is a demand to incorporate the nature in the city in order to meet the wishes of the entire population. The valuation of water, a key component of the quality of the landscape, becomes a key element in this context both for its ecological potential because of their potential for recreational activities. The areas that suffer most impacts are the Permanent Preservation Areas (PPAs) and this paper will be a weighting on the urban interface - PPA. With the study area the basin of the stream of Limoeiro, in the context of the Friendship Fountain Balneary, especially the source contained between residential neighborhoods Maré Mansa and Parque Imperial, the city of Presidente Prudente and Álvares Machado, Sao Paulo, this paper aims to search and use of knowledge about technologies and techniques of environmental restoration, with emphasis on bioengineering, through an environmental characterization of the basin, with a view the incorporation of nature in the lives of the urban population. The methodology includes: literature review priority issues related to the PPAs, linear parks, relevant environmental legislation, environmental characterization of the watershed of the stream Limoeiro; study of technologies and techniques for environmental remediation of soil bioengineering and implementation of parks linear, development of proposals for the environmental recovery of PPA in the basin of the stream Limoeiro, focusing on emerging...

Cette étude visait à générer une carte du potentiel d'érosion pour la Ferme Santa Edwirges, située à Lorena /SP. Les résultats ont etés classifiés en faible, modéré, élève et très élève potentiel d'érosion et la carte obtenue a été comparé par rapport aux autres cartes existantes pour la zone d'étude. La méthodologie proposée se basant sur une application qualitative simple L’équation Universelle de Perte de Sol (USLE ou EUPS), en considérant les parties de l'équation: érodibilité, la topographie et l'utilisation des terres. Les donnés ont etés intégrés par l'algèbre de carte dans l’environnement SIG de ArcGIS. Pour la représentation de chacune de ces parcelles, nous avons utilisé une carte des formations superficielles de la ferme, généré à partir d'une ré-interprétation de la carte géologique, une carte de la pente et une carte d'utilisation des terres, attribuant un poids d’important pour chaque catégorie de ces cartes dans le processus d'érosion et dans l'algèbre proposée. Les résultats obtenus sont compatibles avec les zones identifiées comme les plus critiques sur terrain. La ferme a été identifiée comme de potentiel d'érosion modérée et la partie sud de la ferme le plus critique, suivi du groupe conduit par la zone de cisaillement, par contre les plaines proches des rivières ont eté identifié comme la zone plus stable avec moins de potentiel d'érosionDe la comparaison des résultats de ce travail et d'autres qui ont fait antérieurement dans la zone d’intéresse, qui ont utilisé les paramètres géotechniques dans la représentation de l'érosivité des sols, nous avons pu voir des résultats similaires, en particulier dans les zones à potentiel élevé et faible pour l'érosion. De la discussion et analyse des résultats, la méthodologie proposée à eté validée
