HOW DO FLOODS OCCUR? Floods are caused by excess water: • Rain fall (cyclones or hurricanes) • Rivers rising. • Ice melting. • Tides due to the moon. • Tsunamis.
How do floods cause damage? ď śPlay water damage: This damage basically soaks everything sometimes it can dissolve foundations and make the ground unstable and muddy. ď śRushing water damage: Due to the water crashing into buildings, cars and other things, this is flood water that often kills people and animals.

Principal types of flood Riverine floods â€˘ Slow kinds: Runoff from sustained rainfall or rapid snow melt exceeding the capacity of a river's channel. Causes include heavy rains from monsoons, hurricanes and tropical depressions, foreign winds and warm rain. â€˘ Fast kinds: include flash floods resulting from intense thunderstorms. Estuarine floods Commonly caused by a combination of sea tidal surges caused by storm-force winds. Coastal floods Caused by severe sea storms, or as a result of another hazard. Catastrophic floods Caused by a significant and unexpected event.
