What are five main points you should do to prepare for flooding?
Before a Flood
- Know your flood risk.
- Make a flood emergency plan.
- Build or restock your emergency preparedness kit, including a flashlight, batteries, cash, and first aid supplies.
- Consider buying flood insurance.
- Familiarize yourself with local emergency plans.
What should you do during a flood warning?
Move immediately to higher ground or stay on high ground. Continue to check the media for emergency information. Follow instructions from public safety officials. If advised to evacuate, do so immediately.
How does afforestation help prevent flooding?
Afforestation involves the planting of trees in a drainage basin to increase interception and storage while reducing surface run off. This reduces a river’s discharge and so makes it less likely to flood. When combined with floodplain zoning, afforestation can be very effective at reducing the risk of flooding.
What are the three methods of flood control?
Some of the common techniques used for flood control are the installation of rock beams, rock rip-raps, sand bags, maintenance of normal slopes with vegetation or application of soil cements on steeper slopes and construction or expansion of drainage. Other methods include dykes, dams, retention basins or detention.
What is the best way to prepare for a flood?
Clear debris from gutters. Make sure that you clear any debris from gutters and downspouts to avoid an accumulation of water. Elevate or move your furniture. When flooding is predicted or imminent, move furniture and valuables to a safe place, such as an attic or the highest floor of your home.
What should not be done during floods?
• Ignore rumours, stay calm, don’t panic.
What is the first step in case of flood?
Follow instructions from local emergency officials. Do NOT attempt to shut off electricity if any water is present. Water and live electrical wires can be lethal. Leave your home immediately and do not return until authorities indicate it is safe to do so.
What process does afforestation increase in order to slow down flooding?
Afforestation involves the planting of trees in a drainage basin to increase interception and storage while reducing surface run off. This reduces a river’s discharge and so makes it less likely to flood.
Does afforestation increase flooding?
When deforestation takes place, the top layer of soil can be dislodged – this is also known as soil erosion. When the top layer of soil is unstable, it is unable to retain any of the water that falls on it, resulting in increased surface run-off, which, in turn, increases the risk of flooding.
What is the best way to prevent the flood and drought from happening?
Forests can soak up excess rainwater, preventing run-offs and damage from flooding. By releasing water in the dry season, forests can also help provide clean water and mitigate the effects of droughts.
Where was the flooding in April in Oklahoma?
Heavy rain fell in a short time over parts of west central Oklahoma, producing flash flooding and river flooding along the Washita River that killed 17 people near the town of Hammon, OK. The heavy rainfall totals of 6 to 14 inches occurred over a concentrated area in west central Oklahoma during the evening of April 3 and early morning of the 4th.
How did the Washita River flood in Oklahoma?
As water from these creeks fed into the Washita River, the volume multiplied. A rapidly flowing wave of water, reportedly 2 miles wide at the height of the flood, moved down the river toward the east, and overwhelmed multiple homes just north of Hammon, in Roger Mills County. Many people were washed away with their homes; 17 people were killed.
How many counties were affected by the Oklahoma flood?
A total of 52 of the 77 counties in Oklahoma suffered some type of flood damage. There were 33 counties, the cities of Norman and Shawnee, and 10 counties in Kansas declared flood disaster areas.
Where are the flood control dams in Oklahoma?
As a result, the state of Oklahoma leads the nation in the number of small watershed upstream flood control dams constructed with just over 2,100 dams comprising a $2 billion infrastructure. In fact, the first flood control dam in the nation, Cloud Creek Dam Number 1, was built in 1948 along a tributary to the Washita River near Cordell.
