What is difference between barrage and dam?

A dam is considered to be a more sophisticaled barrier than a barrage. A dam is a barrier of concrete built accross a river to create a body of water for a hydroelectric power station or a reservoir of water and is of greater capacity than a barrage. A barrage is an obstruction in a watercourse to increase the depth of water to facilitate irrigation

How much electricity does the Hoover Dam supply?

It's very difficult to answer questions like this because of the way the US power grid works. Power producing sites put power on the grid, and power consuming sites take power off the grid, and it's not really possible to track exactly what goes where. Think of it this way: the power grid is a big barrel full of water. Las Vegas has a pipe coming out of the barrel, and Hoover Dam has a pipe going into the barrel, but there are many other pipes coming out and going in. Finding out if a particular drop of water flowing through the Las Vegas pipe came from the Hoover Dam pipe would be difficult. The power grid is actually worse than that, because we could theoretically put some dye in the water, but we can't do that with power; an electron is an electron is an electron. That said: Las Vegas actually does not get much of its power from Hoover Dam, since the electric company serving Las Vegas is NV Energy, which owns its own power plants and does not operate the generators at Hoover Dam. NVE's own website states that 70% of their power generation for southern Nevada comes from natural gas fired plants, so at most 30% of Las Vegas' power would come from Hoover Dam (and most likely much less than that). Also, the US Bureau of Reclamation (the agency that operates the generators at the dam) does not list Las Vegas as a recipient of the power generated. They do list the State of Nevada in general (which gets about 23% of the power generated by the dam), but the only specific city in Nevada that's listed is Boulder City, NV.

How much does cost to build a seaport?

The cost to build a seaport can vary significantly based on factors such as location, size, design, and the infrastructure required. On average, the costs can range from hundreds of millions to several billion dollars. For example, constructing a small regional port might cost around $100 million, while large international ports can exceed $1 billion. Additionally, ongoing operational and maintenance expenses must also be considered in the overall investment.

How did grand coulee dam get its name?

Grand Coulee Dam is named for the Grand Coulee, an ancient dry riverbed along the Columbia River. It is actually a glacially-eroded watercourse from vast and sudden prehistoric floods of water and ice, which flowed west from the extinct Lake Mizzoula in Montana, beginning about 18000 years ago.

The lake behind the dam was named Franklin Delano Roosevelt Lake (FDR Lake) for the US President who approved its construction.

In what year did the water go over the spillway at Hoover Dam?

due to a very wet winter the water level in lake mead rose to flood level, the camp grounds and launching ramps where all under water. this took place in 1983

How are the dams affecting the Colorado river?

  1. generates hydroelectricity to power cities near the Colorado river such as Lake Havasu City.

  2. Provides more water to homes for drinking and cooking with.

  3. It prevents flooding in nearby cities

What is a dam built on?

Natural dams are made of earth, or more rarely wood and silt (e.g. beavers). Manmade dams may consist of packed earth, or stone, or concrete.

What is the impact of the construction of dam on the surrounding landforms?

Reservoirs held behind dams affect many ecological aspects of a river. Rivers topography and dynamics depend on a wide range of flows whilst rivers below dams often experience long periods of very stable flow conditions or saw tooth flow patterns caused by releases followed by no releases. Water releases from a reservoir including that exiting a turbine usually contains very little suspended sediment, and this in turn can lead to scouring of river beds and loss of riverbanks; for example, the daily cyclic flow variation caused by the Glen Canyon Dam was a contributor to sand bar erosion. Older dams often lack a fish ladder, which keeps many fish from moving up stream to their natural breeding grounds, causing failure of breeding cycles or blocking of migration paths. Even the presence of a fish ladder does not always prevent a reduction in fish reaching the spawning grounds upstream. In some areas, young fish ("smolt") are transported downstream by barge during parts of the year. Turbine and power-plant designs that have a lower impact upon aquatic life are an active area of research. A large dam can cause the loss of entire ecospheres, including endangered and undiscovered species in the area, and the replacement of the original environment by a new inland lake. Large reservoirs formed behind dams have been indicated in the contribution of seismic activity, due to changes in water load and/or the height of the water table.

What kind of plants are used to make electricity for dams?

In big dams (like hoover or grand coulee), when the water flows through, it spins these huge magnets that creates static electricity in massive amounts that is then sent to a sub station to be processed from there.

How do you make a simple model of dam?

first you get some water then you pour it! first you get some water then you pour it! first you get some water then you pour it! first you get some water then you pour it!

How will building a dam affect people living nearby?

the habitats of the animals around it will be destroyed and the fishes may also lose their habitats due to flooding

Is the three gorges dam sustainable?

Well, there are many reasons as to why the Three Gorges Dam is and is not sustainable.

Sustainable:

  • Will hold up against floods- protecting precious agricultural land and peoples lives.
  • Will protect the Yangtze river from landslides-stops sediment from blocking up the rivers path.

Not sustainable:

  • Will not hold out against typhoons (tornados or hurricanes in America)-they will just rip it up.
  • Will not hold out against huge floods-giant floods will go over the top of the dam-letting water through and causing flooding on the land and increase water levels.

What do dams provide?

Dams are put in place to hold back water. This is generally used to create a water reservoir, but can also sometimes be used as a form of flood control. Hydroelectric dams, like the Hoover Dam, hold back water to create water pressure, to push turbines that generate electricity. In the case of the Hoover Dam, which holds 9.2 trillion gallons of water, extremely massive amounts of water pressure are obtained, and the 17 turbines combined make 2.8GW of power, which is about as much as 3 nuclear power plants.

How does a hydroelectric dam change the type of energy?

There are several. Gravitational potential energy is transformed into linear kinetic energy, which is then transformed into rotational kinetic energy, which is then transformed into electrical energy.

The amount for a small waterpark is about $250 mil. dollars
