India’s rivers are undergoing a drastic change. Due to the pressures of population and development, our perennial rivers are becoming seasonal. Many of the smaller rivers have already vanished. Flood as well as drought are becoming increasingly frequent, as rivers turn unruly during the monsoon, and vanish once the rainy season is over.In every state, perennial rivers are either becoming seasonal or totally going dry.
In Kerala – the Bharatpuzha, in Karnataka – the Kabini, in Tamil Nadu – the Kaveri, Palar and Vaigai, in Odisha – the Musal, in Madhya Pradesh – the Kshipra. Many smaller rivers have already vanished.
Most major rivers are the subject of interstate water disputes.
India’s rivers are dependent on rainfall. Rainfall enters rivers and streams through two main mechanisms. One mechanism is surface flow over land. The second mechanism is through underground flow. Rain seeps into soil and becomes groundwater, which then gradually flows underground and enters streams, rivers etc.Trees help rain seep into soil because living and decaying roots make soil porous by creating a network of well-connected, minuscule channels in the soil. Rainwater seeps into soil with such channels several hundred times faster than it seeps through soil without channels.It is hard to exactly calculate how much of a rivers water comes from this base flow component, so figuring out how much water is actually entering the river has many variables. Estimates for peninsular rivers range between 20-40%. For the Narmada, it is about 20-22%. For the Godavari it is estimated at around 35%.
WE NEED TO HAVE POLICY TO PROTECT THE RIVERS THAT HAVE BEEN PROTECTING US.
