The increasing pollution and the decrease in river water flow have made revival of rivers a non-negotiable need today. The solution is in cleaning the rivers--not in parts but as a whole. Posted on 29 Dec, 2016 02:05 PM

A river is a natural stream of fresh water fed by rain or melting snow during the monsoon. On its onward journey, many tributaries join in and the river and its tributaries form the drainage basin. The river collects the available runoff and groundwater discharge and flows into an ocean or a landlocked water body at the end of its journey.
