The monitored points were Catarina (P1), Marina (P2) beaches and Recanto das Águas (P3), which has a great affluence of people in the summer. The method for the evaluation of the number of fecal and total coliforms in the water and sediment it was Chromocult. The bathing water quality results showed, according to Resolution CONAMA 274/00, that the beaches of the reservoir presented a bathing water quality varying from "Very Good" to "Excellent" in at least 70% of the year. Where your quality was conditioned to the level of the reservoir, in April, with the water level elevation, its classification was "Inappropriate". The number of total coliforms can be related to the extensive cattle breeding activity all around reservoir. With the rainy season, the material produced by such an activity can be carried to the body water. The fecal and total coliforms data on sediment remained low in all sampling stations.

In this scenario, were verified the quality of the waters of the Rio Claro, the stream of Queixada and Ribeirão Jataí, using the method of verification of the Water Quality Index (WQI CETESB). The indices found in ten points studied, in four samples campaigns, were classified as water quality "good," "fair" and "medium." It was also found that the quality parameters BOD (Biochemical Oxygen Demand), Faecal Coliforms, pH and Turbidity did not meet the limits for the waterways of Class 2 CONAMA Resolution No. 357/2005 (BRAZIL, 2005). Moreover, for the most part, the original vegetation of Permanent Preservation Areas (APP) of urban rivers studied was removed or replaced by buildings or by some sort of anthropic occupation. / As atividades antrópicas desenvolvidas no município de Jataí alteram a qualidade das águas dos rios que passam pela área urbanizada devido aos lançamentos de esgotos tratados ou in natura; drenagem urbana; resíduos sólidos, e até mesmo, por processos naturais. Neste cenário, verificou-se a qualidade das águas do Rio Claro, do Córrego do Queixada e do Ribeirão Jataí, utilizando-se o método de verificação do Índice de Qualidade da Água (IQA da CETESB). Os índices encontrados nos dez pontos de coleta estudados, em quatro campanhas de coleta, foram classificados como água de qualidade “boa”, “regular” e “média”. Verificou-se também que os parâmetros de qualidade DBO (Demanda Bioquímica de Oxigênio), Coliformes Fecais, pH e Turbidez não atenderam os limites estabelecidos para os cursos de água da Classe 2 da Resolução CONAMA nº 357/2005 (BRASIL, 2005). Além disso, em sua maior parte, a vegetação original das Áreas de Preservação Permanente (APP) dos rios urbanos estudados foram eliminada e/ou substituída por construções ou por algum tipo de ocupação ou uso antrópico.

Também foi realizada a avaliação da evolução do uso da terra e cobertura vegetal nesta microbacia visando a preservação não somente das águas, mas toda “teia complexa” das relações existentes entre parâmetros físicos, biológicos e antrópicos em uma bacia hidrográfica. A crescente degradação da qualidade dos recursos hídricos devido a ações antrópicas torna necessário o monitoramento da qualidade ambiental desses ecossistemas.

Cinco pontos de amostragem foram determinados ao longo do rio Cabeça além de outros dois pontos no corpo hídrico que recebe a suas águas, o rio Passa Cinco, um a montante e outro a jusante do ponto de encontro de ambos os rios.

The evolution of land use and vegetation cover was also studied to preserve not only the water, but the “complex web” of relations between physical, biological and social parameters in a watershed. Due the increasing degradation of water quality by the human activities is necessary to monitor the environmental quality of these ecosystems. The Cabeça river is a tributary in the Corumbataí river watershed, an environmental unit of extreme economic and social importance due the water potential able to supply the cities of Analândia, Corumbataí, Rio Claro, Santa Gertrudes, Ipeúna, Itirapina and Charqueada and allow to export water to cities located in neighboring watershed, such Araras and Piracicaba, where water problems are serious. Five sampling points were selected over the course of the Cabeça river and other two points on the Passa Cinco river, that receiving the water of that river, one point upstream and one downstream from the point of encounter between the two rivers. Samples were collected once a month during the period from April/2007 to March/2009. The results showed that the BOD and Escherichia coli were above the limits establishing to river class 2 by State Decree 8468/1976 and CONAMA 357/05 Resolution. Iron and pH were also out of the limits recommended by Resolution. The metals Cu, Cr and Ni were not detected during the study period and Cd and Pb were found only in a few samples.

Ongoing development of modern society, based on consumption of goods and services, leads to the increase of compulsoriness of economic agents to face market requirements by increasing the degree of local and regional industrialization. Establishment of new economic activities generates negative pressures on the environment and surface waters, generating increased pollution, manifested by vulnerability of aquatic ecosystems to stressors. Preliminary studies carried out within the doctoral thesis entitled 'Research on the evolution, magnitude and complexity of the impact of economic activities on the East Jiu' include information on characteristic elements of the East Jiu River basin, in accordance with the Water Framework Directive 2000/60/CE. The objectives of the field research aimed to identify economic activities in the eastern Jiu Valley generating an impact on the environment (especially the mining industry, but also timber exploitation and processing, local agriculture, animal husbandry and waste storage), establishing a quarterly monitoring program of the river basin, identification of flora and fauna species and identification of areas vulnerable to potential pollution. Based on observations made in situ and on information obtained from the evolution process of the monitoring program, the appropriate methodologies for assessing physical-chemical and ecological quality of the water were selected. Study of the evolution of the impact generated by economic activities on the East Jiu was carried out by mathematical modelling, with finite volumes, of the East Jiu River basin and plotting of pollutant dispersion maps. The magnitude and complexity of impact generated by economic activities was studied by using a complex system based on fuzzy logic, designed based on interactions between natural and artificial systems, between physical-chemical indicators of water and ecosystem. The research carried out substantiates in development of necessary technical measures to reduce the impact generated by economic activities located in eastern Jiu Valley, without significantly changing the hydrodynamics of the river basin. Following research, during different research stages, methods, techniques and tools were designed and accomplished with the help of which, water and aquatic ecosystems’ quality can be assessed, as well as the impact generated by human activity on the Jiu River, at a given moment and/or continuously.:CONTENT ACKNOWLEDGEMENTS SUMMARY LIST OF FIGURES LIST OF TABLES ABBREVIATIONS INTRODUCTION PURPOSE OF THE THESIS AND RESEARCH METHODOLOGY CHAPTER 1 THE EAST JIUL RIVER HYDROGRAPHIC BASIN 1.1.
