One way of reducing the damage caused by flooding is to remove buildings from flood-prone areas, leaving them as parks or returning them to wilderness. Floodplain buyout programs have been operated in places like New Jersey both before and after Hurricane Sandy , [9] Charlotte, North Carolina , [10] and Missouri. In the United States, FEMA produces flood insurance rate maps that identify areas of future risk, enabling local governments to apply zoning regulations to prevent or minimize property damage.
Buildings and other urban infrastructure can be designed so that even if a flood does happen, the city can recover quickly and costs are minimized. For example, homes can be put on stilts, [12] electrical and HVAC equipment can be put on the roof instead of in the basement, and subway entrances and tunnels can have built-in movable water barriers. An elaborate system of flood way defenses can be found in the Canadian province of Manitoba. As is the case with all north-flowing rivers in the temperate zone of the Northern Hemisphere, snow melt in southern sections may cause river levels to rise before northern sections have had a chance to completely thaw.
This can lead to devastating flooding, as occurred in Winnipeg during the spring of To protect the city from future floods, the Manitoba government undertook the construction of a massive system of diversions, dikes, and flood ways including the Red River Floodway and the Portage Diversion.
The system kept Winnipeg safe during the flood which devastated many communities upriver from Winnipeg, including Grand Forks , North Dakota and Ste. In the United States, the U. Army Corps of Engineers is the lead flood control agency. In the New Orleans Metropolitan Area , 35 percent of which sits below sea level, is protected by hundreds of miles of levees and flood gates.

This system failed catastrophically , with numerous breaks, during Hurricane Katrina in the city proper and in eastern sections of the Metro Area, resulting in the inundation of approximately 50 percent of the metropolitan area, ranging from a few inches to twenty feet in coastal communities. The Morganza Spillway provides a method of diverting water from the Mississippi River when a river flood threatens New Orleans , Baton Rouge and other major cities on the lower Mississippi.
It is the largest of a system of spillways and floodways along the Mississippi. Completed in , the spillway has been opened twice, in and in In an act of successful flood prevention, the federal government offered to buy out flood-prone properties in the United States in order to prevent repeated disasters after the flood across the Midwest.
Several communities accepted and the government, in partnership with the state, bought 25, properties which they converted into wetlands.

These wetlands act as a sponge in storms and in , when the floods returned, the government did not have to expend resources in those areas. D and also constructed a sluice on the Kazuno River [21].
In India , Bangladesh and China , flood diversion areas are rural areas that are deliberately flooded in emergencies in order to protect cities. The consequences of deforestation and changing land use on the risk and severity of flooding are subjects of discussion. In assessing the impacts of Himalayan deforestation on the Ganges-Brahmaputra Lowlands , it was found that forests would not have prevented or significantly reduced flooding in the case of an extreme weather event.
Many have proposed that loss of vegetation deforestation will lead to an increased risk of flooding. With natural forest cover the flood duration should decrease. Reducing the rate of deforestation should improve the incidents and severity of floods. Following the misery and destruction caused by the Great Flood of Paris , the French government built a series of reservoirs called Les Grands Lacs de Seine or Great Lakes which helps remove pressure from the Seine during floods, especially the regular winter flooding.
London is protected from flooding by a huge mechanical barrier across the River Thames , which is raised when the water level reaches a certain point see: Venice has a similar arrangement, although it is already unable to cope with very high tides. The defenses of both London and Venice will be rendered inadequate if sea levels continue to rise. The largest and most elaborate flood defenses can be found in the Netherlands , where they are referred to as Delta Works with the Oosterschelde dam as its crowning achievement.
Emergency Flood Abatement
These works were built in response to the North Sea flood of , in the southwestern part of the Netherlands. The Dutch had already built one of the world's largest dams in the north of the country. The Afsluitdijk closing occurred in It also has a main traffic function, as it completes a ring road around Saint Petersburg. Eleven dams extend for Clean-up activities following floods often pose hazards to workers and volunteers involved in the effort.
Potential dangers include electrical hazards , carbon monoxide exposure, musculoskeletal hazards, heat or cold stress , motor vehicle -related dangers, fire , drowning , and exposure to hazardous materials.
Plumbers Experiences
Because flooded disaster sites are unstable, clean-up workers might encounter sharp jagged debris, biological hazards in the flood water, exposed electrical lines, blood or other body fluids, and animal and human remains. In planning for and reacting to flood disasters, managers provide workers with hard hats , goggles , heavy work gloves, life jackets , and watertight boots with steel toes and insoles. Europe is at the forefront of the flood control technology, with low-lying countries such as the Netherlands and Belgium developing techniques that can serve as examples to other countries facing similar problems and other countries which may soon face these problems.
After Hurricane Katrina , the US state of Louisiana sent politicians to the Netherlands to take a tour of the complex and highly developed flood control system in place in the Netherlands. Regular maintenance of hydraulic structures, however, is another crucial part of flood control. From Wikipedia, the free encyclopedia. For the protocol issue, see Flood control communications.

CHCT members were provided the list of available data for each focal habitat type in addition to a list of possible metrics e. CHCT members used the available data to decide on metrics that could be used to prioritize habitat patches for each focal habitat type. HHP priority habitat maps were incorporated into the Habitat Mapper tool.
