FLOODS
↪ WHAT IS A FLOOD? ↩
Flood is an overflow of water that submerges land that is usually dry. Floods often cause damage to homes and businesses if they are in the natural floodplains of rivers. Standing flood waters can also spread infectious diseases, contain chemical hazards, and cause injuries. The Environment Agency is responsible for flood risk management activities on main rivers, regulating reservoir safety, and providing river flood warnings. It has powers to undertake work on main rivers to fix flooding issues. In addition to the risks of drowning, electrocution and injury that are present in the aftermath of a flood, contamination is a serious threat to your health. Common causes of flood : Heavy rainfall, Overflowing of Rivers and lakes, Melting of Glaciers, Cataclysmic Events and Human-made causes.
Flash floods are particularly dangerous. The centers for Disease control report that over half of all flood-related drownings occur when a vehicle is driven into hazardous floodwater. According to the National Weather Services, a mere 6 inches of fast-moving flood water can knock over an adult. It just takes 12 inches of rushing water to carry away a small car, while 2 feet of rushing water can carry away most vehicles.
When it comes to flooding emergencies, Blackwater Floods are the most dangerous and the most destructive. Because of the grossly unsanitary conditions of the water, porous and absorbent items such as carpets, upholstery and drywall are often unsalvageable. Contact with Greywater or Blackwater can cause water-borne diseases, such as typhoid fever, cholera, leptospirosis and hepatitis A. Vector-borne diseases, such as malaria, dengue and dengue haemorrhagic fever, yellow fever, and West Nile Fever.
Common warning signs include intense rainfall, dam or levee failure as well as other events such as slow moving tropical storms and early snowmelt can all contribute to flooding, whether you live in a flood zone or not. Flash flooding occurs within 6 hours of the rain event. Flooding is a longer term event and may last a week or more. Flooding along rivers is a natural and inevitable part of life.
DID YOU KNOW? The biggest rainfall in a day occurred with the passage of Cyclone Denise in Foc-Foc, La Réunion, an island in the southern Indian Ocean. Some 1.825 meters (71.8 inches) of rain fell over 24 hours, from January 7 to 8, 1966. In 2015, flash flooding killed 129 people. The majority died in cars as they tried to drive through fast moving waters. These raging waters cause extreme destruction; destroying roads, washing away homes, and rising faster than people can react. If enough rain falls fast enough, any place can have a flash flood.
HOW CAN WE MITIGATE A FLOOD?
Flood prevention decreases the potential risk of flood damage to buildings and also reduces the severity of flood damage. — for example planning and zoning, floodplain management, discouraging growth in high risk flood zones or offering outreach and education in a neighborhood can be examples of mitigation. Examples of homeowners mitigation can involve flood insurance purchases.
The approaches to flood mitigation fall into two categories: structural and non-structural. The restoration of landscapes mitigates damage by structural types of mitigation. It includes floodwalls, fur-trees, levees and routes of evacuation. Non-structural action prevents damage by removing individuals and properties from danger zones. They include higher structures, buyouts, permanent relocation, zoning, subdivision and construction codes. Structural solutions have long lost prominence because of the collapse of old dams and floodgates.
Make an Emergency Plan: Create a family emergency communications plan that has an out-of-state contact. Plan where to meet if you get separated. Make a supply kit that includes enough food and water for several days, a flashlight and a whistle. Don’t forget to include your pet in your emergency plan. Remember that some evacuation shelters do not accept pets. Click here to know how to make an emergency plan
Build an emergency kit with the supplies you will need if you have to quickly evacuate your home. Gather supplies, including non-perishable foods, cleaning supplies, and water for several days, in case you must leave immediately. It is recommended that there is at least 3 days’ worth of supplies on hand, including one gallon per day for each person and pet. Click here to know how to make an emergency kit
