If you could have heard of this hydro projects, one is one of the largest projects in our country, which is Bhakra Nangal project. If we look at this Bhakra Nangal project, it has a reservoir which is about 88 kilometers long and 8 kilometers wide.
Detailed Explanation
The Bhakra Nangal Project is one of the largest hydroelectric projects in India, notable for its massive reservoir that stretches 88 kilometers in length and 8 kilometers in width. This size allows for a significant amount of water storage, crucial for generating hydroelectric power and managing water resources.
Examples & Analogies
Think of the Bhakra Nangal Project as a giant water reservoir similar to a huge garden pond, but instead of just being for decoration, it's engineered to store vast amounts of water for generating electricity and supporting agriculture.

The dam is located here which is a concrete dam and having a height of 207 meters approximately, and the length is 500 meters, and width varies from at the top 9 meters, as it goes down the base becomes wider and wider which will be 191 meters.
Detailed Explanation
The dam itself is a concrete structure approximately 207 meters high and 500 meters long. The width at the top is 9 meters, but it broadens to 191 meters at the base. This design is essential for distributing the weight of the water behind the dam, ensuring stability and strength against the immense pressure of the stored water.
Examples & Analogies
Picture the dam as a huge bookend keeping a stack of heavy books steady. The wider base provides support, making sure everything stays in place without tipping over.
