seallock

A seallock is a type of lock used to control the flow of water in a canal or river. It is designed to allow boats to pass through while preventing water from flowing back and forth between the two sides of the canal or river. The seallock consists of a pair of gates that can be opened and closed to control the flow of water. When the gates are closed, the water level on one side of the lock is raised or lowered to match the water level on the other side, allowing boats to pass through without any change in water level. Once the boats have passed through, the gates are opened, and the water levels on both sides are allowed to equalize. Seallocks are commonly used in canals and rivers to facilitate the passage of boats and to control the flow of water. They are an important component of waterway infrastructure and play a crucial role in the transportation of goods and people.
