1. Análise do assoreamento no reservatório de Três Irmãos - SP, utilizando dados topobatimétricos, hidrológicos e técnicas de geoprocessamento / Analysis of siltation in the reservoir of Três Irmãos - SP, using bathymetric data, hydrologic and GIS techniques
O processo de sedimentação em reservatórios gera várias conseqüências, dentre elas, o impacto acumulativo da perda de capacidade de armazenamento destes. Este fato faz com que, dependendo dos usos, eles percam a sua funcionalidade tal como a capacidade de regularização de vazão. Tais efeitos não afetam somente uma única atividade econômica que ve

2. Avaliação da adição de nitrato de amônio para redução de odor nos esgotos de Pereira Barreto - SP: reflexos na qualidade da água do reservatório de Três Irmãos, após dez anos de aplicação / Evaluation of the addition of ammonium nitrate to the sewer system in Pereira Barreto - SP, in order to reduce the odor: reflections upon the quality of the water in the Três Irmãos reservoir, aften ten years of application
It evaluates the alteration of the quality of the water in the region of discharges of domestic effluents into the Três Irmãos reservoir, due to the application, since 1996, of ammonium nitrate into the sewer system of the city of Pereira Barreto. Six trips to collect samples were performed bimonthly between October 2004 and August 2005.The samples were co

3. Modelação das deformações por colapso devidas à ascensão de lençol freático / Modeling of the collapse deformations due to rise of groundwater table
This thesis presents a case history of soil collapse that took place during and after reservoir filling of Três Irmãos dam in Brazil. The construction of this dam and subsequent reservoir filling has raised the local groundwater table up to 20 m, causing soil collapse that affected many buildings. Many field and laboratory tests were conducted to determine

4. A comunidade de peixes dos reservatórios dos trechos médio e baixo rio Tietê, com ênfase nas espécies Plagioscion squamosissimus e Geophagus surinamensis. / Fish community of the reservoirs located on middle and low Tietê River, with emphasis in the introduced species Plagioscion squamosissimus and Geophagus surinamensis.
From sixties, the fish species introduction has been being a constant event in the reservoir system located on middle and low Tietê River - SP, which resulted the success introduction of Plagiosicon squamosissimus and Cichla cf. ocellaris in all these reservoirs. According to this context, the present work objectified characterize the fish community, with f

5. A comunidade de invertebrados bentônicos nos reservatórios de Promissão, Nova Avanhandava e Três Irmãos (Baixo Rio Tietê - SP).
The aim of the present study was to characterize the benthic community of Promissão, Nova Avanhandava and Três Irmãos reservoirs, in relation to the composition of taxa, population densities and also to verify the occurrence of exotics mollusks in this reservoir system. Moreover, it aimed to evaluate possible relations between the physical and chemical ch

6. Analysis of distribution, density and toxicity of cyanobacterial blooms and its toxins in the reservoirs of Middle and Low Tietê river (SP) and its relation with limnological characteristics of this system / Análise da distribuição, densidade e toxicidade de florações de cianobactérias em reservatórios do médio e baixo rio Tietê (SP) e relação com as características limnológicas do sistema
Reservoirs in Brazil, particularly in São Paulo State, are important ecosystems which were built up successively in the last 40 years. Some of these reservoirs, mainly at the Middle and the Low Tietê river cascade system are eutrophic. Frequently cyanobacterial blooms are related to these eutrophic conditions which compromise the multiple use of the reserv

7. Impactos ambientais associados a usina hidreletrica de Tres Irmãos : o fenomeno de ação e reação
Many environmental impacts were caused by the implantation of hydroelectric in Brazil among the decades of 50 and 80. In Sao Paulo State the great reservoirs add a superior area of 6.500Km2 of flooded areas, representing 2,6% of the surface of the State. The importance of that energy for the social and economical Brazilian s development is evident. However,
