Here in this article are basic facts about the causes of the flood and also list and define the different types of floods here we have. What is called flood or how are floods caused?
A flood can also be defined as the overflowing of water that inundates land that is usually dry. This always occurs in the river when the power flow rate exceeds the capacity of the river channel.
Once the flood occurs, it’s caused a lot of damage to nature whereby humans and businesses find it difficult to escape once their location areas are closers to the flood plains of rivers.
However, there are several causes of floods. Floods can be caused by atmospheric conditions that can lead to heavy rain or quick melting of snow and ice. Besides most are caused by Heavy rainfall, Ocean waves coming onshore like storm surges, Melting of snow and ice alongside ice jams, and dam or levees breaking.
Those listed constantly cause the Flood which can affect humans and their businesses. It was also said that the geographies can also make an area closer to the floods. Where we have houses near the river that are often at high risk for flood.
5 Different Types of Floods
1 River Flood
Meanwhile, river flood mostly occurs during the rainy season. Which happens to be when the levels of water rise up over to the top of the river banks. The river flood does happen in all rivers and streams agencies. Which it transfers all particles of small streams to the world’s largest rivers.
Causes of the River flooding
Here are the causes of River flooding include:
- Excessive rain from tropical storm system making landfall.
- result in thunderstorms over the same location for extended periods.
- Combined rainfall and snowmelt.
- Finally, ice jams.
Besides, river floods can suddenly happen or slowly. It’s occurred more often on similar rivers, rivers with steps valleys, rivers that flow over their normal length, and many more.
2 Coastal Flood
The coastal flood is an outpouring of normally dryland areas along the coast with seawater. This can be caused by some cases which are also a result of a combination of sea tidal surges, high winds, and many more
- Tropical cyclones can cause the coastal flood
- Tsunami
- Higher than the average tides.
3 Storm Surge
This is also another type of flood that can be caused by an abnormal rise in the water level of coastal areas over the regular tremendous tide.
Causes of Storm Surge
- Winds
- Waves
- Low atmospheres pressure
However, you can also explore more about Storm Surge on your device’s Chrome or default web browser. But note that this is a tropically dangerous form of flooding. This can flood large coastal areas at the same time and cause flooding very easily.
4 Inland Flooding
Inland flooding does occur inland or not in a coastal area. This means that coastal flooding and storm surge does not occur in inland floods.
Causes of Inland Flooding
- Rainfall is one of the causes of inland floods. Is either happen with a steady rainfall over-serve l days or a short and intense period of time of rainfall?
- Snowmelt
- Paved roads and streets
- Low-capacity drainage equipment
- Dense building
- Low amounts of green space
And also, inland flooding can be caused when the waterways have been blocked by intense.
5 Flash Flood
This can be caused by rain falling rate and rain falling duration. And mostly happen when damns breakout, levees fail, or when the rises of ice jams bring out large amounts of water. And it was said to be dangerous and deadly also.
What are the Causes of Flooding?
As was said earlier, you can find a lot of different causes of flooding. Meanwhile, all floods have their own causes and damages. Here is the list of floods causes
- Heavy rainfall
- Overflowing rivers
- Releasing of dams or broken dams
- Storm surges and tsunamis
- Channels with steep banks
- A lack of vegetation
- Melting snow and ice
In summary, the dangerous aspect of a flood can cause damage to human nature. Whereby, it can lead to loss of lives, carrying people away in fast movement of water, drowning people, damage to homes, businesses, and property, and many more.
There are different types of flood in which they both have their causes and effect of flood. Always beware of water flood because of its damages.
