Non monsoon flows of Indian rivers are declining
Recent evidence shows that monsoon flows in Indian rivers are almost unaffected, but the non-monsoon flows show a declining trend. This has manifested in the form of:
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.
