Concept notes: The Farakka Barrage is a significant water management structure located on the Ganges River in West Bengal, India. It was constructed to address the issue of sedimentation in the Hooghly River, which is a distributary of the Ganges. The barrage helps in maintaining the depth of the river for navigation and also serves as a means to control flooding.
Explanation: The Farakka Barrage is a significant water management structure located on the Ganges River in the Indian state of West Bengal. It is situated in the Murshidabad district, approximately 16.5 kilometers from the border with Bangladesh, near the town of Shibganj. The construction of the Farakka Barrage was initiated in 1961 and completed in 1975. It was designed to address several critical issues related to the Ganges River, particularly the sedimentation in the Hooghly River, which is a distributary of the Ganges and flows through the port city of Kolkata.
The primary purpose of the Farakka Barrage is to maintain the depth of the Hooghly River to ensure navigability for ships and boats. The barrage also serves to control flooding in the lower reaches of the Ganges and to provide a reliable supply of water for irrigation and other purposes. The structure consists of a series of gates that can be opened or closed to regulate the flow of water. During the dry season, the gates are partially closed to divert more water into the Hooghly River, while during the monsoon season, they are opened to allow excess water to flow into the main channel of the Ganges.
The Farakka Barrage has been a subject of controversy due to its impact on the ecology and water distribution between India and Bangladesh. The diversion of water from the Ganges has affected the flow of water into Bangladesh, leading to disputes over water sharing. Despite these challenges, the Farakka Barrage remains a critical infrastructure project for water management in West Bengal and the broader Ganges basin.
Understanding the location and function of the Farakka Barrage is essential for comprehending the geography and water management issues in West Bengal. It is a prime example of how large-scale engineering projects can address complex environmental and economic challenges but also highlight the need for regional cooperation and sustainable water management practices.
