headgates
Water flow regulators
Headgates are the gates or valves at the head of a canal, irrigation ditch, or waterway that control the flow of water into the channel.
They regulate how much water enters a system, making them crucial infrastructure in agricultural regions: The farmer opened the headgates to flood the fields.
In mining, headgates control ventilation or access at tunnel entrances.
