What is flood?
Flooding is an overflowing of water onto land that is normally dry. Floods can happen during heavy rains, when ocean waves come on shore, when snow melts quickly, or when dams or levees break. Damaging flooding may happen with only a ten centimeters of water, or it may cover a house to the rooftop. Floods are the most frequent type of natural disaster and occur when an overflow of water submerges land that is usually dry.
The Three common types of flood are:
1. Fluvial floods or River floods - a fluvial, or river flood, occurs when the water level in a river, lake or stream rises and overflows onto the surrounding banks, shores and neighboring land.
2. Pluvial floods caused by the flash floods and surface water, and
3. Coastal flood caused by the storm surge
Failing to evacuate flooded areas, entering flood waters, or remaining after a flood has passed can result in injury or death. Flooding is a temporary overflow of water onto land that is normally dry. Floods are the most common natural disaster all over the world. Floods may:
- Result from rain, snow, coastal storms, storm surges, and overflows of dams and other water systems.
- Develop slowly or quickly – Flash floods can come with no warning
- Because outages, disrupt transportation, damage buildings, and create landslides.
Just 15 cm of moving water can knock you down, and 30 cm of moving water can sweep your vehicle away.
If you are under a flood warning
1. Find a safe shelter right away.
2. Do not walk, swim, or drive through flood waters. Turn Around, Don’t Drown!
3. Stay off of bridges over fast-moving water.
4. Determine how best to protect yourself based on the type of flooding.
5. Evacuate if told to do so.
6. Move to higher ground or a higher floor.
7. Stay where you are.
How to prepare for flood?
1. Know types of flood risk in your area. Visit your local emergency service website for information.
2. Sign up for emergency warning system. The DORRISS provide you with fast and reliable emergency alerts.
3. If flash flooding is a risk in your location, then monitor potential signs, such as heavy rain.
4. Learn and practice evacuation routes, shelter plans, and flash flood response.
5. Gather supplies in case you have to leave immediately, or if services are cut off. Keep in mind each person’s specific needs, including medication. Obtain extra batteries and charging devices for phones and other critical equipment.
6. Keep important documents in a waterproof container. Create password-protected digital copies.
7. Protect your property. Move valuables to higher levels. De clutter drains and gutters. Install check valves. Consider a sump pump with a battery.
How to survive during the flood?
1. Depending on where you are, and the impact and the warning time of flooding, go to the safe location that you previously identified.
2. If told to evacuate, do so immediately. Never drive around barricades. Local responders use them to safely direct traffic out of flooded areas.
3. Listen to local radio and use DORRISS emergency alerting systems for current emergency information and instructions.
4. Do not walk, swim, or drive through flood waters. Turn Around. Don’t Drown!
5. Stay off bridges over fast-moving water. Fast-moving water can wash bridges away without warning.
6. If your vehicle is trapped in rapidly moving water, then stay inside. If water is rising inside the vehicle, then seek refuge on the roof.
7. If trapped in a building, then go to its highest level. Do not climb into a closed attic. You may become trapped by rising floodwater. Go on the roof only if necessary. Once there, signal for help.
How to stay safe after the flood?
1. Listen to authorities for information and instructions. Return home only when authorities say it is safe.
2. Avoid driving, except in emergencies.
3. Snakes and other animals may be in your house. Wear heavy gloves and boots during clean up.
4. Be aware of the risk of electrocution. Do not touch electrical equipment if it is wet or if you are standing in water. If it is safe to do so, turn off the electricity to prevent electric shock.
5. Avoid wading in floodwater, which can contain dangerous debris and be contaminated. Underground or downed power lines can also electrically charge the water.
6. Use a generator or other gasoline-powered machinery ONLY outdoors and away from windows.
