Types of Dams
Dams are water reservoirs or just a wall-like structure built across a river to retain the water and increase the flow when needed, used for electricity generation, and various other functions.
Arch dam
An arch dam is a concrete dam that is curved upstream in plan. The arch dam is designed so that the force of the water against it. Arch Dams are quite suitable for narrow, steep-sided valleys.
Embankment dam
An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semiplastic mound of various compositions of soil or rock.
Gravity dam
Agravity dam is a structure designed to withstand loads by its own weight and by its resistance to sliding and overturning on its foundation.
Buttress dam
Abuttress dam or hollow dam is a dam with a solid, water-tight upstream side that is supported at intervals on the downstream side by a series of buttresses. They can be constructed on weak foundation because they are less massive than gravity dams.
Coffer dam
Acofferdam is an enclosure built within a body of water to allow the enclosed area to be pumped out. Cofferdams are temporary structures used they are most commonly used to facilitate the construction or repair of dams, piers and bridges.
Diversion dam
Diversion is the sometimes permanent, but most often temporary, re-routing of water from its original location. It used to divert the portion of flow of a river from its natural course.Adiversion dam serves the purpose of raising the eater level in order to redirect the water to the required destination.
Hydropower dam
Hydropower is a method of sustainable energy production.
Hydropower is now used principally for hydroelectric power generation. The efficiency of today's hydroelectric plant is about 90 percent.
Industrial waste dam
An embankment dam, usually built in stages, to create storage for the disposal of waste products from an industrial process. The waste products are conveyed as fine material suspended in water to the reservoir impounded by the embankment.
Masonry dam
Masonry dams are dams made out of masonry – mainly stone and brick, sometimes joined with mortar. They are either the gravity or the archgravity type. It designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it.
Overflow dam
The overflow dam is a dam that allows surplus water over its crest to flow downstream. In overflow dams, the water flows over the top. It is designed to store water and allow surplus water to flow downstream into the riverbed. The overflow dam is a type of Hydraulic Dam.
Regulating dam
Adam impounding a reservoir from which water is released to regulate the flow downstream.
Saddle dam
Saddle dam is given to a water barrier built in a topographic depression or gap on the rim of a reservoir. Some saddle dams limit a reservoir and increase its efficiency.
Saddle dams are placed in a low spot to prevent the inundation of nearby land.
