                       The Flowing Wonders of Deccan Plateau

Introduction:

A vast elevated region in South and Central India known as the Deccan Plateau is known for its unique geographical features and rich biodiversity. The river system of this plateau plays an important role in the region's agriculture, ecological balance, and the livelihoods of millions of people. Primarily dependent on rainfall, these rivers flow through diverse landscapes, including the Western Ghats and the Eastern Ghats, which receive their headwaters from the Deccan Plateau. Most of these rivers flow towards the east, such as Godavari, Krishna, and Kaveri. But some rivers, like Narmada and Tapi, flow westwards and fall into the Arabian Sea. These rivers cut through rugged hills, fertile plains, and deep valleys to create important river basins essential for irrigation, drinking water, hydroelectric power, and sustainable ecosystems. Besides ecological and economic importance, these rivers have cultural and religious importance.
