| Evaluation of surface water quality and detection of possible degradations of fundamental importance for the monitoring of river basin management. Thereby the objective of this work was to evaluate the quality of surface water reservoirs in the basin of the Alto Jaguaribe, Ceará as the chemical parameter for irrigation purposes. The study was conducted in 10 reservoirs that are part of sub-basin of the Alto Jaguaribe. the data of chemical concentrations of the reservoir water were used in a period from 2001 to 2015 the following parameters: electrical conductivity (EC), chloride (Cl-), sodium (Na+), calcium (Ca2+) and magnesium (Mg2+), totaling 750 samples. The data came from the company’s database Water Management (COGERH) available to the Federal... |
