The question asks to identify the Indian river that is commonly referred to as the "Sorrow of Bengal". This nickname is given to a river due to its tendency to cause significant destruction, primarily through floods.

Sorrow of Bengal River Explained

The river known as the "Sorrow of Bengal" is the Damodar River.

Here's why:

• Historical Flooding: Throughout history, the Damodar River has been notorious for its erratic course and devastating floods. Before the construction of dams, the river used to frequently overflow its banks, causing widespread destruction to life and property in the regions it flowed through, particularly in the Burdwan, Hooghly, and Howrah districts of West Bengal.
• Impact on Bengal: These recurrent floods led to immense suffering, displacement, and economic hardship for the people of Bengal, earning it the tragic title "Sorrow of Bengal". The floods disrupted agriculture, destroyed villages, and posed a constant threat to settlements along its banks.
• Control Measures: Significant efforts have been made to control the river's flow and mitigate flooding, most notably with the Damodar Valley Project (DVP), modelled after the Tennessee Valley Authority in the USA. This project involves several dams (like Tilaiya, Konar, Maithon, and Panchet) and barrages to manage water resources, prevent floods, and generate hydroelectric power. While these measures have greatly reduced the severity of the floods, the river's past behaviour cemented its nickname.

Other Rivers Mentioned

Let's briefly look at the other options:

• Hoogly River: This is a distributary of the Ganges River and flows through Kolkata. While it has its own significance, it is not known as the "Sorrow of Bengal".
• Barakar River: This is a major tributary of the Damodar River. It joins the Damodar and contributes to its water flow, but it is the Damodar itself that carries the "Sorrow of Bengal" title.
• Jamuna River: This term usually refers to the Brahmaputra River in Bangladesh or a river in Uttar Pradesh, India. Neither is associated with the "Sorrow of Bengal".
• Son River: This is a major southern tributary of the Ganges, flowing through central India. It does not have the nickname associated with Bengal.

Therefore, the Damodar River is the correct answer due to its historical record of causing severe floods and widespread devastation in the Bengal region.
