Clay dam in India?
VerifiedAnswer: Banasura Sagar Dam
Explanation:
The Banasura Sagar Dam is India's most prominent clay dam, located in the beautiful state of Kerala. This impressive structure stands as a testament to modern engineering and environmental conservation in the Western Ghats region.
Situated in Wayanad district, this dam was constructed across the Karamanathodu tributary of the Kabini River. The dam gets its name from Banasura, a legendary demon king from Hindu mythology who was believed to have ruled this region. Construction of this remarkable clay dam was completed in 1979, making it a relatively modern addition to India's water infrastructure.
What makes Banasura Sagar Dam special is its construction material and technique. Unlike concrete dams, this clay dam is built using earth and clay materials, making it an earthen dam. The dam stands at a height of 25.5 meters and has a length of 685 meters. It creates one of the largest reservoirs in Kerala, with a storage capacity that significantly contributes to the region's irrigation and water supply needs.
The reservoir formed by this dam is not just functional but also incredibly scenic. It has become a popular tourist destination, attracting visitors who come to enjoy boating, trekking, and the breathtaking views of the surrounding hills and islands. The dam creates numerous small islands within the reservoir, adding to its natural beauty and ecological diversity.
From an environmental perspective, the Banasura Sagar Dam plays a crucial role in water conservation and flood control in the region. It helps regulate water flow during monsoon seasons and ensures adequate water supply during drier periods. The dam also supports local agriculture by providing irrigation facilities to farmers in the Wayanad district.
The area around the dam is rich in biodiversity, being part of the Western Ghats ecosystem. It supports various species of flora and fauna, making it an important ecological zone. The dam's design and construction take into consideration the environmental sensitivity of the region, demonstrating how infrastructure development can coexist with nature conservation.
For students studying geography or environmental science, Banasura Sagar Dam serves as an excellent example of how sustainable engineering can meet both human needs and environmental protection. Its clay construction method is particularly noteworthy as it represents an eco-friendly approach to dam building, using locally available materials and causing minimal disruption to the natural landscape.
