Abstract: The present study was designed to demonstrate the seasonal variations in physico-chemical parameters of mixed water of Rivers Ravi and Chenab, for a period of ten months from Feburary to November 2000. Water samples were collected on monthly basis and have been analysed for estimation of Water temperature, Light penetration, Surface tension Density, Specific gravity, Boiling point, Turbidity, pH, D.O., Free CO2, Alkalinity, Acidity, Electric conductivity, Carbonates, Bicarbonates, Total Solids, Total Volatile Solids, Total Dissolved Solids, Air temprature, rain and clouds were also recorded. These parameters were compared with standard water quality indicators to indicate probable pollution in mixed water. The overall water quality of study site remained within the safe limits throughout the study period. An attempt has been made to explain the effect of seasonal changes on physico-chemical charactersitics of mixed water of Rivers Ravi and Chenab.
