Excerpt: A lock is a device for raising and lowering boats between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a fixed chamber in which the water level can be varied; whereas in a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson) that rises and falls. Locks are used to make a river more easily navigable, or to allow a canal to take a reasonably direct line across land that is not level. A pound lock is a type of lock that is used almost exclusively nowadays on canals and rivers. A pound lock has a chamber (the pound) with gates at both ends that control the level of water in the pound. In contrast, an earlier design with a single gate was known as a flash lock. Indirect evidence suggests that pound locks are likely to have been used in antiquity by the Egyptians, the Ptolemaic Greeks and (at least in the Mediterranean area) the Romans. Pound locks were used in ancient China during the Song Dynasty (9601279 AD), having been pioneered by the government official and engineer Qiao Weiyo in 984. They are mentioned by the Chinese polymath Shen Kuo (10311095) in his book Dream Pool Essays (published in 1088), and fully described in the Chinese historical text Song Shi (compiled in 1345). In medieval Europe a type of pound lock was first built in 1373 at Vreeswijk, Netherlands. This pound lo.
