Lock (water Navigation)
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a chamber in a permanently fixed position in which the water level can be varied. (In a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson (engineering), caisson) that rises and falls.) Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Over time, more and larger locks have been used in canals to allow a more direct route to be taken. History Ancient Egypt In Ancient Egypt, the river-locks was probably part of the Canal of the Pharaohs: Ptolemy II is credited by some for being the first to solve the problem of keeping the Nile free of salt water when his engineers invented the lock around 274/273 BC. Ancient China During 960–1279 CE, the natural extension o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Naviglio Di Bereguardo
The Bereguardo Canal () was a navigable canal, part of the Navigli system in Lombardy, Italy. A secondary branch of the Naviglio Grande, it diverges at Abbiategrasso, heading south to Bereguardo (a distance of about ). The Naviglio di Bereguardo, along with the Naviglio Grande and the Naviglio di Pavia, connect Milan to the Ticino, which then connects to the Po and eventually to the sea. The canals, called ''naviglio'' because they were navigable by boats, were an integral part of Milan's dominance over northern Italy, both as a means of transportation as well as agricultural irrigation and, eventually, hydraulic energy for manufacturing. Construction on the canal began in 1420 and was completed in 1470. The principal engineer was Bertola da Novate (1410-1475), sponsored by Francesco Sforza, who constructed the 18 pound locks. The mitre gate, designed by da Novate, was a major improvement to the design of locks. Although da Novate was the first to introduce the concept in ...
