TO STUDY THE WATER QUALITY INDEX OF RIVER KALI USING GIS AND RS TECHNIQUES AND ITS MANAGEMENTHarish Chandra Joshi, Nitika Garg and I.P. Pandey
In western Uttar Pradesh (India), river Kali is one of the most polluted rivers in India. Treatment of Kali river water is a challenging task due to large variety of microorganisms, inorganic and organic chemicals. To assess the water quality index, a systematic study of River Kali in Muzaffarnagar District (U.P) has been carried out and its temporal changes over the seasonal variations due to the physico-chemical changes in properties during the period from October 2015 to April 2016. The findings show that the present condition of water quality of River Kali that is highly polluted because it receives significantly high amount of organic matters, which generally originates from domestic sources and industrial effluents. Oxygen is required by this organic wastes for degradation, it causes depletion of dissolved oxygen in river water. Water samples were analyzed for various heavy metals like nickel, copper, lead, cadmium, chromium, iron, zinc, manganese, magnesium, and arsenic. The water samples of site first, second are slightly polluted while waste water of site third are highly polluted as a result of contamination with industrial wastes and agricultural wastes. To reduce the pollutants in the river it is recommended that strict methods should be adopted. GIS system and RS are the two main tools which are being used in the present study to analyse the water resources development planning surroundings of the river.
