Flood: n. a great flowing or overflowing of water especially over land not usually submerged.

There are four types of floods. They are seacoast, rain, river, and flash floods. Here is a description of each:

Flash flood – a flash flood is when a river or stream suddenly rises and overflows.

Rain flood – a rain flood is when rain from a storm causes water to cover land that is usually dry.

Seacoast flood – a seacoast flood occurs when seawater floods the coast, the water driven in from hurricanes or other storms.

River flood – most rivers flood once every two years. The water covers land where people live, causing a flood.

Before a flood people often put up sand bags to hold off the water.
