A Remote Sensing Approach for Monitoring Seasonal Variations in the Water Quality of Lake Guaiba, Southern Brazil
Abstract: Freshwater resources in the tropics are subjected to high rate of pollution due to algal blooms during the summer and due to particulate and organic waste discharge from urban areas during spring. Landsat TM images were used to calculate biochemical oxygen demand and turbidity of Lake Guaiba in Southern Brazil during 2010–2011. The results obtained were compared with the values derived from a yearlong sampling data which were analyzed in …
