Definition
泄洪道 is a technical term for a flood-relief channel or spillway — a structure built into a dam or reservoir to safely release excess water during heavy rain or flooding. You'll encounter it in news reports about flood control, dam safety, and water management. The word is a compound: 泄洪 ('release floodwater') + 道 ('pathway').
