Flooding in Bangladesh

Context

Parts of India’s northeast border state of Tripura and districts in eastern Bangladesh have recorded heavy rainfall of up to nearly 200 millimeters (about 8 inches) in recent days, which has caused perilous floodwaters to rise.

What caused flooding?

  • Bangladesh attempted to blame India for opening the Dumbur dam upstream of the Gumti River that led to the flooding.
  • However, India’s Ministry of External Affairs clarified that the opening of the Dumbur dam upstream of the Gumti River in Tripura has not caused the current flood situation in districts on Bangladesh's eastern borders.
  • The catchment areas of the Gumti River that flows through India and Bangladesh have witnessed the heaviest rains of this year over the last few days. The flood in Bangladesh is primarily due to waters from these large catchments downstream of the dam.
  • Dumbur dam is located quite far from the border - over 120 Km upstream of Bangladesh. It is a low-height (about 30m) dam that generates power that feeds into a grid from which Bangladesh also draws 40 MW of power from Tripura.
  • The common problem:
    • Floods on the common rivers between India and Bangladesh are a shared problem inflicting suffering to people on both sides and requires close cooperation towards resolving them.
    • India and Bangladesh share 54 common cross-border rivers.
    • India has three water-level observation sites along the 120-km stretch of the river from the Dumbur dam to the Bangladeshi border at Amarpur, Sonamura, and Sonamura 2.
    • The Amarpur station is part of a bilateral protocol under which India provides real-time flood data to Bangladesh.

Fact Box:

  • Gumti River is a trans-boundary river that flows from Tripura into district of Comilla, Bangladesh. Gumti River is the longest and largest river of Tripura.
  • The Gumti flows into Bangladesh’s Chittagong or Chattogram division, where it flows through the key city of Comilla, before emptying into the Meghna, one of three key rivers of Bangladesh along with the Ganga (known as Padma in Bangladesh) and Brahmaputra (known as Jamuna).
