Know Some Basics of Dams
What is the Dam?
A dam is a barrier to store, retain or controls the river water, lake, estuary or underground flow for various purposes such as domestic, industrial and irrigation etc.
Types of Dams
- According to use dams are three types
- Storage Dams
- Diversion Dams
- Detention Dams
- According to materials used dams are classified into two types
- Rigid Dams
- Non Rigid Dams
Rigid Dams are further classified as
- Gravity Dams: Created by concrete or stone masonry and designed to hold back water and resist horizontal pressure of water.
- Arch Dams: Solid Concrete curved upstream dams.
- Masonry Dams: Masonry dams are made of masonry or using stone and brick and sometimes combined usage of stones, bricks with mortar. These are the sub category of the gravity or the arch-gravity type dams.
- Steel Dams: Made of steels, timber or construction materials.
- Buttress Dams: The dams are characterized by watertight upstream side and series of the buttress at the downstream side.
- Earth Dams: Created by a semi-plastic mound of soil, clay, sand, rock etc.
- Embankment Dams: These type of dams are large artificial dam. Embankment Dams are constructed by the semi-plastic mound of soil, clay, sand or rock. A semi-pervious waterproof natural coat is there over the dam.
- Barrages: Barrages are special type of diversion dam, containing of a number of large gates to control the flow of river water. Barrages are constructed with an aim to regulate and stabilize river water elevation upstream specially for flood control or innigation purposes.
Difference Between Dam and Reservoir
Dam: The barrier designed to control the flow of water of a river, lake, estuary or underground flow. Dams are used especially for generating hydropower.
Reservoir: Reservoir is an integral part of the dam. Reservoirs are designed for storage purpose according to the functionality of the dam.

- Dams are created for hydroelectric power generation, industrial water supply, domestic drinking water supply and irrigation purposes.
- Reservoirs around the dams are used for recreation areas for fishing and boating. Thus it boosts local economical activities.
- Dams are beneficial in mitigating and controlling floods in the region.
