Heavy Rainfall
Heavy rainfall is the primary cause of flooding. In case of heavy rain or if it occurs too quickly, there is simply no place for it to go.
Flash floods can result from this.
Overflowing Rivers
There is another reason why floods occur. The floods in rivers do not always need to be caused by heavy rains.
It is how debris in the river or dams can block the flow of water, which can lead to flooding.
