Abstract:

The present study was intended to analyse Water quality of Bhakra-Yamuna link canals in Narwana region, Haryana in order to see the effect of canal interlinking on water quality. Weighted Arithmetic Mean index method was used for the calculation of WQI on the basis of various physico-chemical parameters like pH, electrical conductivity; total dissolved solid, total alkalinity, total hardness, calcium, magnesium, chloride, nitrate, dissolved oxygen and biochemical oxygen demand. The result revealed that in Sirsa branch of Western Yamuna Canal (Site S1), water quality was poor throughout the year whereas, in Barwala link canal of Bhakra Main canal (Site S2), water quality was good and safe for human consumption. After interlinking of canal, water quality was good at Sirsa branch of western Yamuna canal (Site S3) in the absence water from S1 and becomes poor when water is released through S1

Keywords: Water, Bhakra-Yamuna link canals, physico-chemical parameters
