Definition: A floodometer is a device used to measure the potential of a flood or flooding event. It measures the amount of water that would be present in a given area under different conditions, such as low rainfall, high rainfall, and extreme weather events like hurricanes, tornadoes, or droughts. The sensor typically emits a signal when the water level reaches a critical point, allowing emergency responders to assess the potential for flooding and take necessary actions to protect people and property.
