A dam is a big wall to stop water getting through to certain places. It is also used to irrigate water, and some dams, to make hydroelectricity. Hydroelectricity is electricity that comes from water. It is a environment friendly way of getting energy or power.
Dams are, of coarse, found mostly on rivers though always on water of some kind. Some are huge and some are smaller. For example, on the Euphrates River, the Ataturk dam, it very big and is used for quite a few things. It is found in Southeastern Turkey and is the 5th biggest dam in the world.
Generally for big and major dams,motors are alone not used,all this type dam gates will be controlled manually.Because it is not easy to conrol the large dam gates by motors. But for the dams with single gates,used for irrigation purpose,in canals,we can use the synchronous reversible motors to control such type of dams.

hydroelectric dams
Dams are in front of the flow, levees are at the sides.
The purpose of the dams that are found in the state of PA are to prevent water from entering another water source or landform. Dams are often manmade, but can be constructed by animals like beavers.
dams that r used for more than 1 purpose
To control the river and flooding and produce electricity.
AnswerAt least 15.
Dams serve the common purpose of retaining water.Other structures like floodgates or levees are used to manage or water flow into specific land regions.
To stop sedimention of the reservior. These Dams have low level sluices to help carry away sediments.
At independence, in 1947, there were fewer than 300 large dams in India. By the year 2000 the number had grown to over 4000, more than half of them built between 1971 and 1989. India ranks third in the world in dam building, after US and China. While some of these dams were built primarily for flood control, water supply, and hydroelectric power generation, the primary purpose of most Indian dams remains irrigation.

The purpose of building dams is to control water flow, generate hydroelectric power, provide irrigation for agriculture, manage flooding, and create reservoirs for drinking water supply and recreational use. Dams help regulate water resources and support various human activities while also impacting the environment and aquatic ecosystems.
Beaver's live in burrows, lakes, and small wooden island. Yes they live above ground & are often seen... they build dams from wood they collect & sleep in the dams in areas built for this purpose. they are not nocturnal they work in the day.
A structure is identified as an object built for a specific purpose (i.e. dams, bridges, etc...). A bulding is also a structure but with a specific purpose of housing occupants (home, hotel, work offices, etc).
