- Abstract
The objective of this research was to determine the relationship between soil use and water quality in the Juqueri River basin, through the canonical correlations that exist between the parameters that make up the IQW and the changes in soil use in the last 30 years, this from LANDSAT satellite images 5, 7 and 8 through the supervised classification, which determined 6 classes of use. To determine the IQW in the basin, 8 samples were collected in the summer period and 8 in the winter in 2015 and 2016 in 3 points of the basin, in its upper, middle and at its River mouth. The results obtained revealed that the water bodies suffered a decrease in area from 1.1% to 0.68%, decreasing a total of 0.42%. In relation to IQW in some sampling points, values were observed below 51, which is classified as Regular quality water for human consumption. Correlations were found between the decrease in BOD values by urban areas. Therefore, the need for planning the use of land and a continuous management of the water resources of the basin was verified.
