List of Dams in India PDF

Arch Dam:

The dam is a solid concrete dam bent upstream in the plain. It is created so that the hydrostatic pressure pushes against the arch, causing it to straighten and strengthen the structure.

Gravity Dam:

Dams constructed from concrete or stone, or brick are gravity dams. These dams in India are developed to hold back water by using only the weight of the material and its resistance against the foundation.

Arch-Gravity Dam:

This dam possesses the characteristics of an arch dam and a gravity dam. It curves upstream in a narrowing arc that heads most of the water pressure against the canyon rock walls.

Barrages:

A diversion dam in India with a low head comprising several large gates that can be opened or closed to maintain the water passing through.

Embankment Dams:

It is a type of big artificial dam. Embankment Dams are formed by the placement and compaction of a complex semi-plastic mound of various soil, sand, clay, or rock compositions.

Rock-Fills Dams:

These dams are embankments of compacted, free-draining granular earth with an impermeable zone.

Concrete-face rock-fill dams:

The dams are rock-filled with concrete slabs on their upstream face. The design provides the concrete slab as an impenetrable wall to stop leakage.
