Bihar
Mahabodhi Buddhist temple, built in the 2nd century ce, Bodh Gaya, Bihar, India.
The Ganges (Ganga) River naturally divides the state of Bihar into two distinct physical regions: the North Bihar Plains and the South Bihar Plains. Together, these areas form a significant portion of the middle Gangetic Plain.1
- North Bihar Plains: This region is a flat, low-lying alluvial area situated less than 250 feet (75 metres) above sea level. It is characterized by rivers flowing from the Himalayas, such as the Gandak and Kosi, which frequently shift their channels and make the area prone to flooding.1
- South Bihar Plains: The landscape here is more varied, featuring hills that rise from the alluvial plains. The soil is primarily composed of older alluvium, and the region includes the Kaimur Plateau in the southwest. Unlike the northern region, the southern rivers are generally smaller, with the exception of the Son River.1
