Concept
Subtopic 3.1: Parts of the northern plain: Bhabar, Terai, Bhangar, Khadar, Chaur, Man
- Terai: a narrow west–east band below the Siwalik range; flat, damp and marshy. Just south lies the Upterai, lower than Terai and also swampy.
- Bhabar: a belt of gravel and sand, about 10–12 km wide, deposited by streams at the foot of the Someshwar hills.
- Bhangar (Bangar): old alluvium forming natural embankments and doab areas, about 7.8 m higher than the surroundings.
- Between old (Bhangar) and new (Khadar) alluvium there is a clearly visible middle slope.
- Khadar: new alluvium between the Gandak and Kosi; flooded almost every year, very fertile, and develops along river banks.
- Chaur: low land of the northern plain that stays filled with water in the rainy season. Man: shapes like oxbow (cow-hoof) lakes formed by rivers.
- Diara: flood-related landform at places in the Ganga's flow region; found in Saran, Champaran, Muzaffarpur, Darbhanga, Purnia and Saharsa along with chaur and chhaadan.
