flood barriers
River overflow blockers
Flood barriers are structures designed to prevent water from inundating land during floods, storm surges, or high tides.
They range from permanent installations like seawalls and levees to temporary systems deployed when flooding threatens: The city activated its flood barriers as the hurricane approached.
The term often refers specifically to movable barriers that can be raised or lowered as needed.
