Which term describes the technique used to stop liquid flow by blocking a channel?

• A. Damming
• B. Diversion
• C. Diking
• D. Dilution

Answer: (A)

Damming is the technique of stopping liquid flow by placing a barrier across the path of the liquid to block its movement. By creating a temporary barrier, you halt or slow the flow in a channel, giving responders time to isolate the hazard and set up further controls. This differs from diverting flow, which aims to reroute the liquid away from an area rather than stopping it entirely; diking involves building a perimeter to contain liquid, typically along shorelines or around a containment area; and dilution focuses on reducing hazard by mixing the liquid with more water or other substances rather than stopping its movement.
