The major contributor of flooding is rainfall and is dependent on various factors such as distribution or the area it covers, amount of rain, soil porosity (ability of soil to take up water) and the period of rainfall. Prolonged light showers over a region can also cause the land to overflow with water.
Moreover, why do floods happen?
The simplest explanation for flooding is heavy rains. You do not necessarily need to have heavy rains to experience flooding in your area. Broken dams, storm surges and tsunamis, channels with steep sides, urban drainage basins, a lack of vegetation, and melting snow and ice in addition are a few more items to take a look at.
Flooding along rivers is a natural and inevitable part of life. Some floods occur seasonally when winter or spring rains, coupled with melting snows, fill river basins with too much water, too quickly.
The physical facts of a warming world mean that the air can now hold more moisture. This means that downpours are heavier and likely to cause more flooding. According to the UK Met Office, the amount of rain from extremely wet days in the UK has increased by 17% in the most recent decade (2008-2017) compared to 1961-1990.

Flooding of river Main Inundations caused by heavy rain and destruction of floodplain. If you thought that floods are natural disasters that happened only in poorer continents like Africa and Asia, then you are wrong. First, not all floods are caused by nature . They are man-made too.
This begs the question “How is the environment adapted to flood?”
Floods occur naturally. They are part of the water cycle, and the environment is adapted to flooding. Wetlands along river banks, lakes, and estuaries absorb flood waters. Wetland vegetation, such as trees, grasses, and sedges, slow the speed of flood waters and more evenly distribute their energy.
Why do humans try to prevent floods?
This is what happened . Floods happen when there is too much water, and this water submerges the dry land. The way to prevent floods, Mr Monbiot began by explaining, was to slow this excess water on its journey back to the oceans.
Why to have people feared floods?

Our study set out to investigate the effect of community participation in strengthening the relationship between disaster risk information dissemination and disaster preparedness. Flooding in Accra.
