When thinking about a flood, many individuals envision a hurricane or a wall of water racing down a river. While those types of events often produce floods, nothing quite so dramatic has to occur for flooding to take place. A flood can simply be an overflow of water that submerges land that is usually dry.
Flood can also be defined at a more technical level. According to the National Flood Insurance Program, a flood is defined as:
A general and temporary condition of partial or complete inundation of two or more acres of normally dry land area or of two or more properties […] from one of the following:
- Overflow of inland or tidal waters
- Unusual and rapid accumulation or runoff of surface waters from any source
- Collapse or subsidence of land along the shore of a lake or similar body of water as a result of erosion or undermining caused by waves or currents of water exceeding anticipated cyclical levels that result in a flood as defined above
A flood event may look very different depending on where you are, whether that's in a low-lying coastal area or alongside a steep riverbank, but in all cases, you need to know how to handle the situation.
