Seasonal variation of temperature dependent physico-chemical parameters of a coastal River Bhadra, Bangladesh

This analysis observed the seasonal variation in the temperature dependent physico-chemical parameters [ph, transparency, salinity, electrical conductivity (ec), total dissolved solid (tds), total alkalinity, total acidity, dissolved oxygen (do) and free dissolved co2] of surface water in a coastal river in bangladesh. composite samples from four different sampling points that considered high and low tides were collected and analyzed in three main consecutive seasons: rainy, winter and summer. the study has revealed that most physico-chemical parameters are not a serious problem for bhadra river eco-system and water quality shows significant seasonal changes. the statistical analysis unveiled a positive correlation of temperature with ph, transparency, salinity, ec, tds, total alkalinity, total acidity and free dissolved co2 but only negative correlation with do.
