Proposta de implantação do índice de abrangência espacial de monitoramento - IAEM por meio da análise da evolução da rede de qualidade das águas superficiais do estado de São Paulo / Proposal of implementation for an Spatial Coverage Monitoring Index - SCMI by temporal analysis of the evolution of the inland waters quality network of São Paulo State

Midaglia, Carmen Lucia Vergueiro 04 December 2009 (has links)
Esta pesquisa de doutorado faz uma avaliação correlacional entre a evolução espacial da rede de monitoramento de qualidade das águas interiores do Estado de São Paulo, através do número de pontos de amostragem e sua respectiva densidade espacial ao longo dos 30 anos de existência da mesma e o crescimento populacional, através da densidade populacional dos municípios inseridos nas 22 unidades de gerenciamento de recursos hídricos do Estado de São Paulo. Analisa também se estes pontos mantiveram a capacidade de representar o status da qualidade da água em função do crescimento populacional, e se é necessário expandir ou adensar a rede em determinadas regiões. Esta comparação ficou mais racional com o uso dos recursos das geotecnologias e da análise multicritério aplicada ao planejamento e gerenciamento de recursos hídricos, com a construção do SIG SP_WATERNET e através da criação de um índice de avaliação do monitoramento que relaciona as 22 unidades espacialmente e ao longo do período estudado. Este índice pode ressaltar o grau de abrangência e de vulnerabilidade da rede de monitoramento das águas interiores superficiais no Estado de São Paulo. / This Ph.D. research makes a correlational evaluation between the spatial evolution of the monitoring network of inland surface waters of State of São Paulo, through the number of sampling points and its density throughout the 30 years of existence of same and the population growth (urbanization) and the population density in the 22 units of water management units of the São Paulo State. It also analyzes if these points had kept the capacity to represent the status of the quality of the water in function of the population growth, and if it is necessary to expand or to rearrange the network in some regions. This comparison was more rational with the use of the resources of the geo-information applied for water resources planning and management, with the construction of SIG SP_WATERNET and with the proposal of an multi-criteria evaluation monitoring index concerning the 22 water management units throughout a studied period. This index can point out the coverage or the vulnerability of the monitoring efficiency of the superficial waters network of São Paulo State.

Researches regarding the evolution, magnitude and complexity of the impact generated by the economic activities on the East Jiu River

Simion, Alexandru Florin 07 July 2023 (has links)
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.
