Dams

First of all call up a local wildlife resource office to make sure you can do this some states won't let you. The first choice and cheapest would be to move soil and gravel into a part of the creek to dam it up, then mat it down. Over a month or so soil will start building up on the back side of the dam. This will strengthen your dam. Also you'll need to add spillways on the side so your property won't flood. I did this to build up a drinking hole for my horses and its working great. If you want to spend some money then dam up the creek (like I said above) higher up the stream then down stream take rebar and space it 6in. Apart and then weld horizontally across 6in. Then go 1 foot further and do the same now you should have two evenly spaced crossed rebar. Then take two pieces of sheet metal and put on outside of each rebar. Fill with concrete, remove sheet metal, and destroy soil dam.

selection of site for the dam : It must satisfied geological condition.

The Hoover Dam is only one dam. If you are talking about all the dams on the Colorado River there are six dams Glen Canyon dam, Hoover dam, Davis dam, Parker dam, Paulo Verde Diversion dam, and Imperial dam.

Because these all are close to the Indus River

Dams are extremely expensive to build and must be built to a very high standard.

The high cost of dam construction means that they must operate for many decades to become profitable.

The flooding of large areas of land means that the natural environment is destroyed.

People living in villages and towns that are in the valley to be flooded, must move out. This means that they lose their farms and businesses. In some countries, people are forcibly removed so that hydro-power schemes can go ahead.

The building of large dams can cause serious geological damage. For example, the building of the Hoover Dam in the USA triggered a number of earth quakes and has depressed the earth's surface at its location.

Although modern planning and design of dams is good, in the past old dams have been known to be breached (the dam gives under the weight of water in the lake). This has led to deaths and flooding.

Dams built blocking the progress of a river in one country usually means that the water supply from the same river in the following country is out of their control. This can lead to serious problems between neighbouring countries.

Building a large dam alters the natural water table level. For example, the building of the Aswan Dam in Egypt has altered the level of the water table. This is slowly leading to damage of many of its ancient monuments as salts and destructive minerals are deposited in the stone work from 'rising damp' caused by the changing water table level.

The Hoover Dam was built over five years from 1930 - 1935. Its reservoir holds 9.2 trillion gallons of water and produces 2.8GW of power, roughly as much as 3 nuclear power stations.

the disadvantages are if it rains too much, the river would flood, and if the flow of water is too strong that would break the dam and the lower coarse will be easily flooded and it would all just be a real waste of thousands of pounds/dollars/euros whatever that could have been used on something else important.

It is also possible that the dam could overflow, flooding the nearby areas and weakening the upper works of the dam.This is not likely, but it's possible

The Hoover Dam does not make energy. Energy, according to the first law of thermodynamics, can never be made.

The Hoover Dam converts the energy stored in running water by way of 17 turbines and electric generators into electric power. These turbines have a combined capacity of 2078MW, producing 4000 GWh per year.

The decision to build the Water Tower came in 1895, one year after a severe water shortage forced the cancellation of classes. It was the first elevated steel water tower west of the Mississippi. Standing 168 feet above campus, the tank itself was 40 feet tall and 24 feet in diameter and held 162,000 gallons. The use of the Water Tower was discontinued in 1978 when the university switched to a city water system. It was placed on the National Register of Historic Places in 1981, and in 1987, it was restored. In 2007, the American Water Works Association presented an award to Iowa State University, naming the Marston Water Tower, an "American Water Landmark."

Men made lake are redirected rivers into a zone to form a lake and they are also called reservoir. A natural lake is done by glacier when they melted and they where filled with water by the rivers around.They are also lakes that are made by people and did not occur naturally in the landscape.

The Grand Coulee Dam is not located in Washington, D.C. It is located in the U.S. state of Washington. Olympia is the capital city of the U.S. state of Washington.

A weir is also called a low-head dam, so weirs are type of dam. Typically non-regulated so excess water simply flows over the top.
A dam is large (or very large), like the Hoover Dam. A weir is very much smaller and you'd be more likely to find one across a stream than a river.

1.2 to 2.5 billion dollars

it would cost about nearly $150,00 ( including the plumbing and hiring people to do it for you, because i do not think you will do this by yourself

Ø including toilets and urinals, about 3 toilets and 3 urinals, two sinks, two hand dryers and hiring the people to actually install plumbing and for woman's bathroom 5 toilets and two hand dryers and two sinks.

A dam built across a river will obviously have a major effect on the river valley upstream of the dam which will be flooded as the new storage reservoir fills. Less obvious is that the river downstream of the dam will also be significantly affected. Large dam projects are highly individual in their design, geological setting and the construction materials used to build them. They are also individual in their impact on their environment. Some large dam projects in tropical Africa have created lakes hundreds of kilometres long in areas which had large local populations. The major impacts that these projects had on the plant, animal and human population of the area have been well documented, however it would be a mistake to assume that all dam projects necessarily have similar major impacts on the environment.

Some adverse effects of building a dam are easy to mitigate during the design of the dam as the following example shows. Fifty years ago a typical dam could release water only from the bottom of the storage reservoir. This water was very different from the water that would have flowed down the river before the building of the dam. Water from the bottom of a storage is usually cold and depleted in oxygen compared to normal river water and this had adverse effects on animal life in the river downstream of the dam. Since about the 1980s dam outlet works are usually specifically designed so that the adverse effects described above do not occur when water is released from the dam. Today's dams have an intake tower with withdrawal ports at different levels so that water can be released from the top layer of the reservoir regardless of the storage level at the time.

Provision of fish ladders is another example where dam design can remove or reduce an adverse effect of dam building. Today every reasonable effort is usually made to reduce the effect of the dam project on the environment eg borrow areas for clay, sand and gravel construction materials needed to build the dam are located, if possible, in the area which will be flooded by the reservoir so that the disturbed areas will not be visible after the dam is completed.

Not all adverse effects can be so easily removed. Building a dam changes forever the flow regime in the river: floods are much reduced in frequency and size and the natural pattern of short duration floods and long periods of low flows is changed to a less variable flow regime. In fact the reduction in flooding may be one of the reasons for building the dam in the first place. Flooding is damaging to humans and their property but may be necessary in the life cycles of some species of trees, fish and birds. It may be possible to at least partially mitigate these adverse effects on the natural environment by arranging water releases from the dam at specific times of the year to mimic the natural flooding that occurred before the dam was built.

they poured the concrete into boxes with cooling tubes running through them. curing concrete produces heat and the vast size of the dam produces insulation so the concrete in the centre would still be curing for another 50 years yet

The largest dam in the Philippines is the San Roque dam.

Providing irrigation water for nearby farmlands

ANSWER

A dam is an embankment/a dike made of concrete or earth or other material to form

a water reservoir or a hydroelectric reservoir or a defensive barrier against the sea.

It is called a Weir.

The Aswan Dam was built to control the niles constant flooding. The Aswan Dam had a trade-off. It promoted good fising and created electricity for factories, but also grows crops that kill plants and have disease carrying snails.
