Floods can cause extensive damage to homes, infrastructure, and the environment. They occur when there is an overflow of water onto normally dry land. Floods can be caused by heavy rainfall, melting snow, or dam failures. They can result in loss of life, displacement of people, and destruction of crops. It is important to be prepared for floods and to take necessary precautions to minimize their impact.

Floods Facts for Kids

  • Floods are when land usually dry gets covered by water.
  • They can be caused by heavy rain or melting snow.
  • Rivers can flood if they get too full.
  • Flash floods happen quickly, with little warning.
  • Floods can damage homes and roads.
  • They can also harm wildlife habitats.
  • It’s important to move to high ground in a flood.
  • Never walk or drive through floodwater.
  • Floods can bring mud and debris.
  • Preparation can reduce damage from floods.

It is estimated that floods cause more deaths and property damage than other weather-related catastrophes. In just two feet of water, an automobile can lose its balance. Six inches of running water is more than enough to cause someone to lose their balance.

Natural and human causes of floods include:

  • Flooding is most commonly caused by heavy rains. Rainwater doesn’t drain nearly as fast as it should. Essentially, drainage systems clog, and water rises.

  • Concrete urban drainage basins don’t allow water to sink into the ground. When those drainage basins are full, low-lying areas flood.

  • Flooding caused by storm surges and tsunamis: Storm surges are associated with hurricanes and other storms, and tsunamis result from underwater earthquakes.

  • Flooding occurs frequently in rivers and other channels with steep sides when there is rapid runoff into lakes, rivers, and reservoirs.

  • If you live near a river and areas upstream suffer severe rains, your river could overflow.

  • American infrastructure was built in the 20th century, so it is aging. Heavy rains and rising water levels can cause aging dams to crumble and spill torrents of water onto careless homes.

  • Flash flooding can occur if there is little vegetation to prevent water from draining.

  • Spring flooding is caused by snowmelt in winter. They have to go somewhere when the snow melts.

There are several types of floods, including:

River flood

In a river, a flood occurs when the water rises above the banks. There is a possibility of flooding in every riverand stream, especially larger ones. Often, river flooding is caused by tropical storms, persistent thunderstorms, snowmelt combined with rainfall, and ice jams. Melting snow or rain raises water levels above riverbanks and floods nearby areas.

Groundwater flood

Floods caused by underground water are called groundwater floods, and they occur when there is a lot of rain. Standing water may last for weeks or months before the Earth can absorb it. This increases the risk of long-term health issues and property damage.

Coastal flood

Storm surges, high winds, or waves cause coastal floods. Climate change will increase the threat of flooding in coastal communities. Most Americans live in coastal regions, with Florida, Louisiana, California, New Jersey, and New York among the states most susceptible to coastal flooding.

Flash flood

Flash floods are the most deadly. A broken dam or severe rain causes them. Since they occur so quickly, people may not have time to flee. Often, flash floods occur near steep slopes or dry riverbeds. In a flash flood, a dry riverbed can fill up quickly. There can be 20-foot walls of water in flash floods.

Sewage flood

A sudden, intense rainfall overwhelms sewage pipes or treatment facilities, causing sewage flooding. A sewage leak from a pipe, drain, toilet, sink, or shower causes the most uncomfortable floods. A quick response and in-depth clean-up are essential in these circumstances.

A flood can be extremely powerful

Six inches of swift water can knock someone over. Avoid walking through flooded areas. It is often deeper than you think and may contain harmful debris or contamination.

66% of flood-related deaths are caused by drivers navigating too-deep water. If you’re unsure of the depth of the water, don’t drive through it. Two feet of water can carry away a little car, and 12 inches can carry away most vehicles.

Sometimes floods are helpful

Floods aren’t always bad. Water is needed for farming and drinking, so towns have always been built along rivers. Rich, damp soil is sometimes left behind by muddy flood waters. Nile River flooding aided ancient Egyptian crops.

In floods, chemicals can spread

If there is a flood, move to the highest floor. If your skin comes in contact with floodwater, you need to wash it with soap and sterilized water since you don’t know what could be in it.

Swamps act as sponges in floods

Flood surges are gradually released from wetlands after the peak surge. Three million gallons of water can be held in an acre of wetlands when saturated to a depth of one foot.

Essential items must be regularly stocked in flood-prone areas

In a flood-prone area, stock up on personal hygiene items, nonperishable foods, 3 gallons of water per person for three days, a battery-operated radio for weather reports, and extra batteries.

Take floods seriously because they can cause other disasters

Floods are the most common natural calamity after wildfires. 90% of all natural disasters declared by the President involve flooding. Floods are more common than other natural disasters, but people don’t take floods seriously, too.

Floodplains are crucial

Floodplains make up only 2% of the Earth’s land surface, but they contribute 25% of ecosystem services. Floodplains are low-lying areas around rivers and other water bodies that flood frequently. Floodplains are the surrounding area’s “lifeblood” due to their regular flooding.

Flood losses are increasing

Heavy rainfall events and changes in land use resulted in more floods despite spending billions on flood protection. Annual flood losses rose from $6 billion to $10 billion in the first decade of the new century. For instance, in the Midwestern United States, the population grew by 10% while the land area increased by 35% between 1950 and 2000, leading to an increase in impervious surfaces that increased runoff and flooding.

Lack of food could also result from flooding

According to FEMA, over 25% of flood insurance claims are for buildings outside high-risk floodplains. Every American is at risk of flooding, whether in a floodplain or not.
