Floodplains and Flooding

• A floodplain is a low-lying area adjacent to a body of water that is prone to flooding.
• The primary cause of flooding during tropical storms and hurricanes is heavy rainfall and storm surges.
• People building in unmitigated floodplains often have high insurance premiums because of the high risk of flooding.

Characteristics of Floods

• A flood can be considered as a minimum of 1 square meter of land area temporarily covered with water.
• Floods can consist of freshwater, saltwater, or a combination of both.
• A storm surge is a rise in sea level due to strong winds and low atmospheric pressure during tropical storms and hurricanes.

Types of Flooding

• Flash flooding is characterized by a rapid rise in water level, often caused by heavy rainfall, storm surges, or dam failures.
