How do floods cause damage for class 3 in easy language
Answers
Floods have large social consequences for communities and individuals. As most people are well aware, the immediate impacts of flooding include loss of human life, damage to property, destruction of crops, loss of livestock, and deterioration of health conditions owing to waterborne diseases.
Answer:
Causes of Floods:
Flood is usually a result of natural causes. It may also be caused by man-made factors. It causes huge damage to life and property. There are many different causes leading to flooding. Some prominent among them include:
1)Massive Rainfall
Drainage systems and the effective infrastructure design aid during heavy rains. They help the drainage of excess water into reservoirs in an easy way. But in cases of heavy rainfall, the systems stop working. Thus flood is caused.
2)Overflowing of the Rivers
The people living along the river always have a risk of life from the overflowing of the Rivers. To prevent such a situation, a string of dams are built. However, if these dams are not managed properly, they may cause flooding and huge damage.
3)Collapsed Dams
In the event of huge rainfall, the dams built begin to collapse. Thus, causing the flood situation to become even critical for the people living around.
Snowmelt
At the time of the high melting of snow due to heavy precipitation and other factors, the situation of flooding arises. Adopting sustainable measures for heavy precipitation can help in dealing with the flooding situation.
4)Deforestation
The cutting of trees in a reckless manner i.e. deforestation is also a major cause of man-made flooding. Trees prevent soil erosion and also the loss of crops. The vegetation is also enriched as a result of more and more trees. This also blocks the massive flow of rain, thus preventing flooding.
5)Climate change
The climatic changes caused due to human practices also add to the risk of flooding. Human beings cut trees in a large number, thus affecting the process of photosynthesis. Thus increased level of carbon-di-oxide in the atmosphere cause changes in climate posing threats of natural disasters like floods etc.
6)Emission of Greenhouse Gases
The burning of fossil fuels, the industrial influences, the pollution all is depleting the level of the ozone layer and increasing the level of greenhouse gases, becoming a major cause of man-made flooding.
7)Other Factors
The broken supply lines cause the outflow of water but lead to less damage. Also, there is water flow from the washing machines. Furthermore, overflow from dishwashers worsens the situation. Also, the lack of proper sewage systems adds to the destruction of this natural disaster.
Thus, a flood can be caused both due to natural causes as well as it can be a human-made flood.
