The northeast and eastern part of the Union territory which is surrounded by Sahyadri Mountains of Western ghats exhibit hilly and rugged terrain. The part of Dadra and Nagar Haveli which lies in the centre is plain and fertile as it lies under the watershed. This alluvial region has a fertile soil owing to the contact with Daman Ganga River originating in Maharashtra.
This river rises in the Western Ghat and passing through the watershed areas of Dadra and Nagar Haveli falls into the Arabian Sea. This river has three tributaries - Golak, Sakartod and Pipariya which join the river in Dadra. Forest cover over the place is also appreciable and home to a large variety of flora and fauna.
