STUDIES ON THE EFFECT OF SEASONAL VARIATIONS ON PHYSICAL AND CHEMICAL CHARACTERISTICS OF MIXED WATER FROM RIVERS RAVI AND CHENAB AT UNION SITE IN PAKISTAN

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 February to November 2000. Water samples were collected on monthly basis and have been analyzed 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, Total Volatile Dissolved Solids. Air temperature, 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 the 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 characteristics of mixed water of Rivers Ravi and Chenab.
