Floods may be man-made or Acts of nature.

• A. True
• B. False
• C. Sometimes
• D. Unknown

Answer: (A)

Floods can result from natural hydrological processes as well as human activities. Natural drivers include heavy rainfall, rapid snowmelt, storms, and rivers overflowing their banks. Human actions can cause or worsen floods through dam or levee failures, improper reservoir management, deforestation, and urban development that increases runoff or reduces drainage capacity. Often a natural flood is intensified by altered land use or infrastructure, and conversely, failures in infrastructure can produce floods even if rainfall isn’t extreme. Because floods can arise from either natural events or human factors, the statement is true. Saying it’s only sometimes, false, or unknown misses the real range of causes.
