Identifying the Stone Masonry Dam
Dams are constructed using various materials and techniques, leading to different types such as concrete dams, earth-fill dams, rock-fill dams, and masonry dams. A stone masonry dam is built using stones laid in mortar, which is a traditional construction method.
Let's examine the types of the dams listed in the options:
- Nagarjuna Sagar Dam: This dam is built across the Krishna River. It is renowned for being one of the largest stone masonry dams in the world. It was constructed using traditional hand-laid stone masonry techniques.
- Bhakra Nangal Dam: This is a concrete gravity dam built across the Sutlej River. Concrete gravity dams rely on their immense weight to hold back the water.
- Hirakud Dam: Located across the Mahanadi River, the Hirakud Dam is primarily an earth-fill dam. It also incorporates concrete sections.
- Tehri Dam: Situated on the Bhagirathi River, the Tehri Dam is a multi-purpose rock and earth-fill embankment dam.
Comparing the construction types, it is clear that the Nagarjuna Sagar Dam is the one built using stone masonry.
| Dam Name | Primary Construction Type | River |
|---|---|---|
| Nagarjuna Sagar Dam | Stone Masonry | Krishna River |
| Bhakra Nangal Dam | Concrete Gravity | Sutlej River |
| Hirakud Dam | Earth-fill & Concrete | Mahanadi River |
| Tehri Dam | Rock and Earth-fill Embankment | Bhagirathi River |
Based on the construction materials, Nagarjuna Sagar Dam stands out as a prime example of a stone masonry dam among the given options.
