A tidal barrage is a dam or a weir built across the inlet to a bay or river mouth. There are gates, or sluices, that open to let water in as the tide rises, and out after it falls. This moving water spins turbines to generate electricity.

∙ 12y agoA tidal barrage is rather like a dam across a river, except it has to allow the water to move in both directions. Some barrages then are movable, which adds a lot to their cost. Barrages have electricity turbines inside and the moving water generates electricity, just as it does in a dam.

What are the advantages of tidal barrages?
no sea, no tides, so no TIDAL BARRAGES :D
Which dams use tidal power?
A dam used for tidal power is called a barrage. Such dams exist in a number of places: Rance River, in France Bay of Fundy, in Canada Kislaya Guba, in Russia Other barrages are under consideration. See the related link, below, for more information.
What is the minimum tidal energy required for a practical tidal plant?
That depends on the kind of plant. There are two major types:1. Tidal turbines2. tidal barrages1. Tidal turbines are like wind-turbines but underwater. They need a current speed of at least 1m/s to start producing energy but current models are not economically viable for anything below 2m/s2. Tidal barrages are like dams across a bay or an estuary. Theyutilizethe difference in water level between high and low tide. They open their gates as the tide comes in to allow the water to collect behind the dam. at the highest point of the tide the gates close until low tide is reached. the water is then release via turbines until the water level behind the dam is equal to the sea level. When the tide comes in again the cycle repeats. These kind of tidal plants need a difference between high and low tide of at least 5-7 meters although the bigger the difference the better.
When are the tidal currents strongest?
When are the tidal currents strongest?
What is a word for a high tidal wave?
tidal surge
What are the advantages of tidal barrages?
no sea, no tides, so no TIDAL BARRAGES :D
Do citezens of Maine use tidal power in Maine?
We don't use tidal power in Maine because we don't have any tidal barrages in Maine.
Why does Switzerland not use tidal barrages?
Because they have no seashore probably.because they have no sea
How is the energy from the ocean utilized?
For generating energy from the power of the waves or tidal-barrages.
What is the purpose of tidal energy?
The purpose of tidal energy is to be used as a resource in hydropower, a renewable source of energy. Tidal energy can be created by barrages, fences, or turbines.
How can tidal power benefit a community other than being a clean renewable energy resource?
The barrages can help reduce flooding
What are the limitations of using tidal energy?
Tidal energy is only available on the coast. Some locations are better than others for tidal energy because of the tidal range - for example, the North West of Australia has a very large tidal range.Converting tidal energy to electrical energy may require the construction of channels or barrages which may impact on the environment.
What is a renewable energy source that uses water?
# Hydro-electricity (dams, rivers, tidal barrages, water wheels) # Tidal power # Wave power # Ocean Thermal energy (the difference in temperature between surface water and deep water)
What environmental problems that could be cause by tidal barrages?
yes it does it causes great amound of problems also causes babys to suffocate and the pope to come to England to sort it out
Is tidal energy environmentally impact free?
No, there is some impact from building barrages or channels and the effect on fish migration. However, after the initial setup there are no carbon emissions and the energy produced is renewable.
Could tidal power keep the moon in perpetual motion as well as generating surplus power for use on Earth?
Tidal power is caused by the moon (largely). Tidal power has no effect on the moon.Yes, tidal power, if it is harnessed properly by wave motion machines, dams and barrages, has enough power to generate all the Earth's electricity needs. However, this power is difficult to capture. Dams and river barrages are large and cause some damage to the environment and obstruction to river travel.Various experiments are underway trying to find suitable ways of harnessing the power of tides and ocean waves. No one has discovered a cheap and easy way to do it yet.
What is the problem when using tidal energy?
The dams and barrages often have to be built across quite a long channel and this can be expensiveThe dams and barrages sometimes interfere with fish movements or shipping.Places suitable for tidal power are sometimes far away from the electricity grid. Connecting wires over long distances loses an amount of power.Holding back the tide allows silt to build up on the river bed, thus reducing the water flow over a number of years.
