- Upper Ganges Plain: This region is located in the northern part of the Ganges basin, covering the states of Uttarakhand and Uttar Pradesh in India. It experiences flooding during the monsoon season due to heavy rainfall and the release of water from glaciers in the Himalayas.
- Middle Ganges Plain: The Middle Ganges Plain is situated in the central part of the basin and includes the states of Bihar and Jharkhand in India. This area is prone to flooding due to the convergence of several tributaries of the Ganges, including the Son, Gandak, and Kosi rivers.
- Lower Ganges Plain: The Lower Ganges Plain is located in the eastern part of the basin, covering the state of West Bengal in India and parts of Bangladesh. This region experiences significant flooding due to the heavy rainfall during the monsoon season and the discharge of water from the upstream areas. The Ganges River merges with the Brahmaputra River in Bangladesh and forms the Ganges Delta, which is one of the largest deltas in the world.
The flood plains along the Ganges are densely populated and support extensive agriculture, but they are also vulnerable to flooding hazards. Floods in these areas can cause significant damage to crops, infrastructure, and property, and can also lead to loss of lives.
