• From the north to the south, the northern plains can be divided into three major zones: the Bhabar, the Tarai and the alluvial plains.
• The alluvial plains can be further divided into the Khadar and the Bhangar.
• Bhabar is a narrow belt ranging between 8-10 km parallel to the Shiwalik foothills at
the break-up of the slope. As a result of this, the streams and rivers coming from the
mountains deposit heavy materials of rocks and boulders, and at times, disappear in this
zone.
• South of the Bhabar is the Tarai belt, with an approximate width of 10-20 km where most of the streams and rivers re-emerge without having any properly demarcated channel, thereby, creating marshy and swampy conditions known as the Tarai. This has a luxurious growth of natural vegetation and houses a varied wildlife.
• The south of Tarai is a belt consisting of old and new alluvial deposits known as the
Bhangar and Khadar respectively.
• Bhabar is the older alluvium occupying higher grounds.
• Khadar is the newer alluvium covering the low lying flood plains.
