Bhabar or Bhabhar is a region south of the Lower Himalayas and the Sivalik Hills in Garhwal and Kumaon, India.[1] The Bhabhar region contains some of the largest cities of Kumaon and Garhwal: Dehradun, Haridwar, Haldwani, Rishikesh, Ramnagar, Tanakpur and Kotdwar. It is the alluvial apron of sediments washed down from the Sivaliks along the northern edge of the Indo-Gangetic Plain.
The Indo-Gangetic Plains are generally thought of as a flat region with no variations, although this isn't true. The plains can be classified into four regions on the basis of relief features. The Bhabar is a belt of 8–16 km lying parellel to the slopes of the Sivaliks, where the river descending from the mountains deposit pebbles. The streams flow through the pebbles the region, hence disappearing from sight. They re-emerge only after some distance south, in the relief feature Terai.
