A flood is one of natural disaster that caused by an overflow water that submerges land which is usually dry.  The European Union (EU) Floods Directive defines a flood as a covering by water of land not normally covered by water.Some floods can occur suddenly and quickly. Others take days or more.

There are several types of flood. Periodic floods occur naturally on many rivers, forming an area known as the flood plain. These river floods usually result from heavy rain, sometimes combined with melting snow, which causes the rivers to overflow their banks. A flood that rises and falls rapidly with little or no advance warning is called a flash flood.

When floods happen, the water can carry along object. Flooding is very dangerous for human being. It also has great erosive power and can be extremely destructive.
