Assam, the eastern most state of the Indian sub-continent,Ferry ghat guwahati extends from 22o19' to 28o16' North Latitude and 89o42' to 96o30' East Longitude between the foot hills of the Eastern Himalayas and the Patkai and Naga Ranges. Assam is bordered in the North and East by the Kingdom of Bhutan and Arunachal Pradesh. Along the south lies Nagaland, Manipur and Mizoram. Meghalaya lies to her South-West, Bengal and Bangladesh to her West. Assam is connected with the rest of the Indian Union by a narrow corridor in West Bengal that runs for 56km below the foothills of Bhutan and Sikkim.


The state is divided into three broad geographic units:

  1. The lower and central Assam hills, known as the Shillong Plateau

  2. The Barail ranges and the low hilly terrains of Mizo hills

  3. The Alluvial valley of Brahmaputra, Dhansiri and the Barak river



(III) The alluvial plains of Assam consist of two distinct parts:

a) the valley of the Brahmaputra and its tributaries and  b) the Barak valley.

These are separated from each other by the water shed of the Shillong plateau and the Barail ranges.

The Brahmaputra valley separates the sub-Himalayan foothills from the Shillong plateau and the Patkai-Naga hill ranges. The Mizo hills and the Barail ranges die out towards the west and south west into the plains of Cachar, which is a part of Surma-Kusiyara valley.
