The dry season had less water volume thus the ionconcentration might be higher. Moreover, the conductivity was affected by the impacts of human activities such as agriculture, for example the raising of livestock and the discharge of urban
wastewaters (Figures 4, 5). MK8 had a higher turbidity than other sites, with the highest value of 288 NTU. The underlying reason for the high turbidity in this watershed was soil erosion, as well as landscape morphology and seasonal changes.
