What is defined as an overflow of inland or tidal waters?

• A. Flood
• B. Surge
• C. Overflow
• D. Lyophilization

Answer: (A)

A flood is specifically defined as the overflow of inland or tidal waters, impacting land that is usually dry. This can occur due to various reasons, such as heavy rainfall, rapid snowmelt, or storm surges caused by hurricanes. Flooding can lead to significant property damage, disruption of communities, and environmental impact.

The term "surge" typically refers to a sudden increase in water levels, often associated with storms or tsunamis, but it does not encompass the broader definition of inundation linked to floods. "Overflow" is a general term and does not specifically imply the large-scale impact or the specific conditions that characterize a flood. "Lyophilization," on the other hand, is a process used in food preservation or pharmaceuticals and is entirely unrelated to water overflow or flood definitions. Hence, the term flood captures the essence of inundation accurately as defined in the question.
