A flood is an overflow of water. Floods are very hard to deal with.
Floods are most commonly made due to an overflowing river, a dam break, snowmelt, or heavy rainfall. Less commonly happening are tsunamis, storm surge. The most deadly flooding was in 1931 in China and killed between 2,000,000 and 4,000,000 people.[1] The Kerala flood in India was another flood that has destroyed people's houses.
During a flood, people try to move themselves and their most precious belongings to higher ground quickly. The process of leaving homes in search of a safe place is called a flood evacuation. Floods have inspired myths and legends, especially the story of the great flood.[source?]
