Tripura was known as 'Hill Tipperah' and the very nomenclature is suggestive of its hilly nature of undulating surface made uneven by inter-pressed low hills. The general altitude differs between 750m to 15m from MSL. The physiography tends to flatten towards west. However, in some places the terrain is inaccessible and highly undulating. The ILinga (Longitudinal valleys)lands are juxtaposed in between the numerous tilla (hillocks) lands, which are the fertile agricultural lands. They are well known for paddy cultivation and recharge capacity of groundwater resource. A series of hill ranges running North South divide the territory into broad parallel valleys, consisting of undulating tilla(hillocks) covered with jungle & meandering streams. There are six principal hill ranges in the State increasing in height as one moves towards East. Of the six principal ranges, Baramura, Deotamura and Atharamura ranges partly fall within West Tripura.

1. Baramura Deotamura Range: The portion of the above ranges lying in West Tripura District is the Baramura range, which is almost 47km wide. It has the highest peak of Saisum Sib (249m). The average height ranges between 200m to 500m.

2. Atharamura Range: This range starts from Amarpur Sub-Division of South T ripura District, then enters the Khowai Sub-Division of West T ripura and runs along the border of West T ripura and Dhalai District. The highest peak in the West Tripura istrict is Niungnawra (481m)
Structurally, the State represents the western fringe of the typical 'ridge and valley !structurall province of the late tertiary fold mountain belt, commonly known as the Indo-Burma Ranges (Purbachal Range) (Source:ZASI, TSPCB, Tripura)

The terrain of Tripura consists of parallel hills and ridges running in a north-west to south-east direction and with alternating narrow valleys. The range of hills rises from the plains of Sylhet in Bangladesh at the north and proceeds southwards until they join the hills of Chittagong hill tracts east. The eastern range of the Jampui is situated at an elevation of 914 m above MSL and the western range of the Baramura Deotamura with elevation of 244m above msl is the lowest.Betlingsib in Phuldungsai with a height of 939m is the highest point of the Jampui hill range of Tripura.

The Physiography map has been prepared based on the contours. The map is divided into three categories:

High Physiography Zone (Hills)

It is seen that almost the entire North and Dhalai Districts are having high physiography. High physiography areas i.e. the Baramura and Atharamura hill ranges are also observed in the West and South Districts. The Blocks of Chhamanu, Oasda, Jampui Hill, Manu, Ambassa, Salema, T ulashikhar and part of Padmabil, Mandai, Bagafa, Amarpur, Kila, Satchand, Hrishyamukh, Satchand, Rupaichara fall in the high physiography zone.

Medium Physiography(Undulating land)

Medium categories are mainly observed in the North Tripura District in the Blocks of Damchera, Pecharthal, Kumarghat and in a part of Chamanu amd Dasda Blocks. A northern part of Hezamura and Padmabil fall under medium physiography zone.

L ow Physiography Zone (Plains)

The 'low' physiography area has been observed mainly in the West and South Districts. Dharmanagar and Kailashahar Sub-divisions of North T ripura District are also having low
physiography areas.
