👉Different Types of Dams
💫A dam is a hydraulic structure built across a river to store water, control floods, generate hydropower, and support irrigation.
1️⃣ Gravity Dam
Resists water pressure by its own weight.
Made mainly of concrete or masonry.
Suitable for strong rock foundations.
2️⃣ Arch Dam
Curved in plan.
Transfers water pressure to the valley sides.
Economical in narrow rocky gorges.
3️⃣ Buttress Dam
Consists of a deck supported by buttresses.
Uses less concrete than a gravity dam.
Suitable where material savings are important.
4️⃣ Embankment Dam
Constructed from earth, rockfill, or both.
Flexible and suitable for wide valleys.
Most common type of dam worldwide.
5️⃣ RCC (Roller Compacted Concrete) Dam
Built using compacted concrete layers.
Faster and more economical construction.
Widely used for large modern projects.
🫵Conclusion
The selection of a dam depends on site conditions, foundation strength, valley shape, available materials, and project requirements.
