Radial Sensor
An Overview Of Mobile Flood Barriers
Flood panels are used throughout the world. They are distinct and unique in their purpose and design. Some of the gates are used to control small amounts of water using mitered barriers. Other gates are used to control massive volumes of water and protect property and people.
Radial and fuse gates are most often seen on dams. These types of barriers divert water from dams and are often used for hydro-energy plants. Radial gates are controlled both manually and automatically and open when the water in a dam reaches a certain level. When used for hydro-energy, the radial gate is opened and water is cycled through the plant, then returned to the dam.
Fuse gates are stationery pilings that release water when it reaches the top of a dam. These barriers do not allow an operator to control the flow of water from the dam and are not used in areas where there is a need to control the release of water.
The improvement and development of mobile flood gates has grown to include protection of major cities. These gates are versatile and functional. When water is encroaching from the ocean, the gates are lowered on a feeder river or major waterway to block the flow of water into the city.
Towers located near the installation area activate the flood barriers. The gates lower to a specific water level. When water reaches above that level, the barrier stops it. These barriers protect the city from being flooded as ocean water rises.
The use of these barriers to stop encroachment of the sea on major cities has been used since 1982. As more cities have been threatened by seawater flooding, the use of the barriers has increased.
Research and studies have been done on this type of protection for several years. Scientists are concerned about the effects on the oceanic eco-system when the exchange of water from the feeder rivers to the ocean is disrupted. Some studies have shown that there is a significant impact to important nutrients for ocean life when there is a disruption in water exchange.
Another concern about mobile barriers is related to the fact that this method of controlling water levels does not allow for the user of hydro-energy systems that could significantly reduce the need for fossil fuels in the cities where the barriers are used.
The size of the mobile barriers varies. In some areas they are used on a feeder river and require space that would otherwise be used by ships. This reduces the ability of docks to generate revenue on those docks.
In some cities the barriers are anchored in the ocean and are activated from stationery sites via radio transmission. These gates are activated when the tide rises each day and significantly reduce the ability of water to be exchanged enough to adequately support micro-organisms and sea life.
As the oceans continue to rise the use of aluminum flood shields will continue to rise. The home flood barriers take, on average, between ten and twenty years to be completed. The planning for the size of the gates is based on predictions of future needs so that there is no need to replace the gates once they have been installed.
