Tippera Surface a part of area mainly in Comilla district lying west of tripura hills in India. It has been uplifted 1.22m to 1.83m in relation to the adjacent floodplain during the Recent time. It is also known as Tippera-Noakhali Clay Plain. The drainage now developed in the uplifted area is mainly artificial, displaying a network of roughly rectangular drains for irrigation. In contrast, the recent floodplain shows a braiding and meandering drainage pattern. The hilly region of Tripura Hills is characterised by dendritic stream pattern. The soil of the Tippera surface is slightly more oxidised than the floodplain deposits. [M Abu Bakr]
