Floodplain is defined as which?

• A. Land used for flood control structures
• B. Any land area susceptible to flooding by water from any source
• C. Area above sea level
• D. Zone for water drainage only

Answer: (B)

Floodplain refers to land that can be covered by floodwaters during flood events. The best-fitting description is any land area susceptible to flooding by water from any source. This recognizes that flooding can come from rivers overflowing, heavy rainfall causing runoff, coastal or storm surge, or other sources, not just a single cause. Floodplains are typically adjacent to watercourses and are shaped by past floods; they may be inundated periodically even if they’re not currently wet. They aren’t defined by being land used for flood-control structures, nor simply as land above sea level or as a zone for drainage alone.
