Deccan Plateau




The Deccan Plateau is a large plateau in India, making up the majority of the southern part of the country. It rises a hundred meters high in the north, rising further to more than a kilometre high in the south, forming a raised triangle nested within the familiar downward-pointing triangle of the Indian subcontinent's coastline.

It extends over eight Indian states and encompasses a wide range of habitats, covering most of central and southern India.

It is located between three mountain ranges: the Western Ghats form its western boundary, and the Eastern Ghats its eastern boundary. Each rises from their respective nearby coastal plains and nearly meet at the southern tip of India. It is separated from the Gangetic plain to the north by the Satpura and Vindhya Ranges, which form its northern boundary.

The name Deccan is an anglicised form of the Prakrit word dakkhin.

The Deccan Plateau lies south of the Indo-Gangetic plain. The Western Ghats Mountain Range is tall and blocks the moisture from the southwest monsoon from reaching the Deccan Plateau, so the region receives very little rainfall. The eastern Deccan Plateau is at a lower elevation spanning the southeastern coast of India. Its forests are also relatively dry but serve to retain the rain to form streams that feed into rivers that flow into basins and then into the Bay of Bengal.

Most Deccan plateau rivers flow from west to east. The Godavari River and its tributaries, including the Indravati River, drain most of the northern portion of the plateau, rising in the Western Ghats and flowing east towards the Bay of Bengal. The Tungabhadra River, Krishna River and its tributaries, including the Bhima River, which also run from west to east, drain the central portion of the plateau. The southernmost portion of the plateau is drained by the Kaveri River, which rises in the Western Ghats of Karnataka and bends south to break through the Nilgiri Hills at Hogenakal Falls into Tamil Nadu, then forming the Sivasamudram Falls at the island town of Shivanasamudra, the second-biggest waterfall in India and the sixteenth-largest in the world,before flowing into the Stanley Reservoir and the Mettur Dam that created the reservoir and finally emptying into the Bay of Bengal.

The two main rivers which do not flow into the Bay Of Bengal are the Narmada and Tapti. They start in the Eastern Ghats and flow into the Arabian sea. All Deccan plateau rivers depend on the rains and dry up in the summers.

The climate of the region varies from semi-arid climate in the north to tropical in most of the region with distinct wet and dry seasons. Rain falls during the monsoon season from about June to October. March to June can be very dry and hot with temperatures exceeding 40°C regularly.
