- A dam is a man-made structure built across a river. Most dams are built to control river flow, improve navigation, and regulate flooding. However, some dams are built to produce hydroelectric power. Hydroelectric power is produced as water passes through a dam, and into a river below. The more water that passes through a dam, the more energy is produced. Once a dam is built, an artificial man-made lake is created behind the dam.

- The second type of dam known to have been built was an earth dam called Nimrod's Dam in Mesopotamia around 2000 BC. Earth dams are massive dams similar to gravity dams except they are made of soil. The dam is made watertight, with a core wall and filled with an impervious center usually made of clays.

Lesson: Water Resources: Why Do We Build Dams? A dam is built to control water through placement of a blockage of earth, rock and/or concrete across a stream or river. Dams are usually constructed to store water in a reservoir, which is then used for a variety of applications such as irrigation and municipal water supplies.

Types of Hydropower Plants Some hydropower plants use dams and some do not. The images below show both types of hydropower plants. Many dams were built for other purposes and hydropower was added later. In the United States, there are about 80,000 dams of which only 2,400 produce power.

Dams and Reservoirs Normally buttress dams are made of concrete and feature a series braces called buttresses along the downstream side of the dam to prevent the natural flow of water. The Daniel-Johnson Dam in Quebec, Canada is a multiple arch buttress dam.In the U.S., the most common type of dam is the embankment dam. These are large dams made out of soil and rock which use their weight to hold back water. To prevent water from moving through them, embankment dams also have a thick waterproof core.The Tarbela Dam in Pakistan is the world’s largest embankment dam. reservoir is a man-made lake that is primarily used for storing water. They can also be defined as the specific bodies of water formed by the construction of a dam. For example, the Hetch Hetchy Reservoir in California’s Yosemite National Park is the body of water created and held back by the O’Shaughnessy Dam.

How Hydroelectric Energy Works The dam with the largest impoundment is Hoover Dam, on the Colorado River in Nevada, which stores approximately 30 million acre-feet of water. The dam that provides the most hydroelectric power in the United States is Grand Coulee Dam, on the Columbia River in Washington, which generates 6180 megawatts (MW) of power.

Dam Milling dams were introduced which the Muslim engineers called the Pul-i-Bulaiti. The first was built at Shustar on the River Karun, Iran, and many of these were later built in other parts of the Islamic world. Water was conducted from the back of the dam through a large pipe to drive a water wheel and watermill.

Hydroelectric power makes big comeback at US dams The project involves drilling two holes in the 110-foot high, mile-long dam and running water through two turbines. Missouri River Energy Services, a Sioux Falls, S.D.-based not-for-profit utility that provides power to 61 cities, has the license to build the power plant at an estimated cost of $260 million.ydroelectricity provides about 7 percent of the nation’s power using about 2,500 dams. But those dams are just a fraction of the 80,000 in the United States. Most were built for flood control, to aid in river navigation or to create recreational areas. So they do not have power plants.

hydroelectric energy Water crashing over the fall line is full of energy. A famous example of this is the hydroelectric plant at Niagara Falls, which spans the border between the United States and Canada. Hydroelectric energy generated by Niagara Falls is split between the U.S. state of New York and the Canadian province of Ontario.

Dam Early dam building took place in Mesopotamia and the Middle East. Dams were used to control the water level, for Mesopotamia's weather affected the Tigris and Euphrates rivers, and could be quite unpredictable. The earliest known dam is the Jawa Dam in Jordan, 100 kilometres (62 mi) northeast of the capital Amman.This gravity dam featured an originally 9 m (30 ft) high and 1 m (3 ft 3 in) wide stone wall, supported by a 50 m (160 ft) wide earth rampart. The structure is dated to 3000 BC.he Report of the World Commission on Dams also includes in the large category, dams, such as barrages, which are between 5 and 15 metres (16 and 49 ft) high with a reservoir capacity of more than 3 million cubic metres (2,400 acre·ft).

Hydroelectric Power Hydroelectric power is the production of power by using the gravitational force of falling or flowing water. Hydroelectric power is the most widely used form of renewable energy. Hydro power supplied an estimated 715,000 MW in 2005. This was approximately 19% of the world's electricity and accounted for over 63% of the electricity harnessed from renewable sources.
