Flood is the overflowing of water from the streams and other bodies of water or an accumulation of rainwater in low-lying areas. Flood can cause severe damages to lives and properties.
Causes of Flood
Intense and prolonged rainfall
Increased urbanization and coastal development
Improper garbage disposal
Failure of levees and dams
Diversion of natural waterways
Types of Flood
River flood is the overflowing of the river when runoff exceeds the capacity of channels or depression and flooding the adjacent low-lying areas called “floodplain”.
Flash flood happens when a very short period of unusually heavy rainfall occurs in a mountainous or hilly area. Most casualties are due to flash floods.
A coastal flood occurs when strong onshore winds push the water inland and cause a rise in sea levels. Worst cases could occur in heavy rains coincide with the occurrence of high tide.
Things To Do
Preparing for flood is a shared responsibility:
– Be aware ow often your location is likely to be flooded and to what extent.
– Know the flood warning system in your community and be sure your family knows it.
– Keep informed of daily weather conditions.
– Know the designated evacuation areas of your family and livestock and assign family members specific instructions and responsibilities according to an evacuation plan.
– Prepare a handy emergency supply kit with first aid, canned food and can opener, water, clothing, blanket, battery-operated radio, flashlights, and extra batteries.
– Securely anchor weak dwellings and items.
– Listen to your radio for emergency instructions.
– If advised to evacuate, DO SO. Don’t panic, move to a safe area before access is cut off by flood waters.
– Store drinking water in containers, water service may be interrupted.
– Turn off electricity at the main switch in the building before evacuating and also lock your house.
Get involved with the disaster risk management programs of your Barangay Disaster Risk Reduction and Management Committee (BDRRMC). Here are things that you can do:
Stay calm and do the following:
– Avoid areas subject to sudden flooding.
– Do not attempt to cross rivers of flowing streams where water is above the knee.
– Beware of water recovered roads and bridges.
– Avoid unnecessary exposure to the elements.
– Do not go swimming or boating in swollen rivers.
– Eat only well-cooked food, protect leftovers against contamination.
– Drink clean or preferably boiled water ONLY.
– Re-enter the dwellings with caution using a flashlight, lanterns or torches. Flammables may be inside.
– Be alert for free hazards like broken electric wires.
– Do not eat food and drink water until they have been checked for flood water contamination.
– Report broken utility lines (electricity, water, gas, and telephone) to appropriate agencies/authorities.
– Do not turn on the main switch or use appliances and other equipment until they have been checked by a competent electrician.
– Consult health authorities for immunization requirements.
– Do not go “sight-seeing” in disaster areas. Your presence might hamper rescue and other emergency operations.
