The most common natural disaster in the US, according to Ready.gov, is flooding. But even though they are common occurrences, floods – and the situations that lead to them – are not always easy to understand. Here are the basics you need to know about flooding, and some factors that can increase the risk of one's hands in your area.
What is a flood?
Simply put, a flood when water contemplates is an area of land that is normally dry. When the amount of water is more than a natural or artificial drainage system can handle, floods can occur, says US Climate Resilience Toolkit.
A flood can occur suddenly or happen gradually ̵
What increases the risk of flooding?
A flood can occur at any time, but there are some situations that in particular increase the likelihood of experiencing a flood, according to National Weather Service:
- Tropical Systems: Tropical storms and hurricanes can generate heavy rain and strong winds that produce storm disturbances that can flood coastal and inland areas.
- Heavy precipitation: Intense storms can release large amounts of precipitation leading to water buildup. This can lead to flooding of floods that flood rivers and dry land.
- Snow melting: Ready.gov notes that a cubic foot of snow consists of several liters of water. When frozen temperatures rise and snow begins to melt, the ground cannot absorb the water because it is frozen or over-saturated.
- Ice and debris stops: Ice cubes or debris flowing down rivers or streams can create jams that cause water to overflow upstream.
- Compromised streams or ponds: If a pond or leaf fails, or if the water level rises and goes out over the structure, the flood may occur.
Where do floods occur?
A flood can happen anywhere, according to the National Serious Storms Laboratory. But the agency says there are some areas that may be more vulnerable to floods than others:
- Dense urban areas: These areas are exposed to flooding because roads, pavements and other coated elements cannot suck up rainwater, which increases water runoff . A heavy rainfall can also flood storm drains and result in a flood, creating uncertain conditions for underground parking garages or subway.
- Areas along or near rivers: Heavy rain can cause floods near rivers that can be exacerbated by a dust or livelihood. Mountains can also contribute to a rapid increase in currents or rivers, as water is rapidly flowing down.
- Burns and fires in fires: These areas may be more likely to flood due to dry land or limited vegetation that prevents heavy rain from soaking.
Bottom line is that it is important to understand that a flood can happen somewhere. Consider signing up for local community warnings and doing what you can prepare, which may include purchasing a flood insurance.
