Description
Summary:The present study sought to develop a methodology to analyse water quality based on the concepts and methods of climate and climatology. Accordingly, the researchers attempted to relate hydro- and limno-meteorological techniques and methodologies to a rhythmic analysis technique developed within the context of the Brazilian geographical climatology. Their goal was to assess and analyse cyanobacterial blooms, the main index of water quality for the reservoirs of the Alto Tiete Basin and consequently, the Metropolitan Region of Sao Paulo, an area of high environmental complexity due to its high degree of development and high population density. The rhythmic and integrated analysis showed that the process of cyanobacterial blooms is dependent on a combination of meteorological factors as temperature and wind intensity that may disrupt the stability of the reservoir, providing the conditions necessary for the development of cyanobacteria during the stabilisation process.
