    Passage 3ª¥

    Canals are watercourses constructed to improve and extend natural waterways.  They are generally built to facilitate transportation, but from the beginning they have been used for many additional purposes including draining swamps, irrigating land for cultivation and promoting economic development.

    Canals are often classified by the size of vessel they can accommodate.  Some small local canals, which are able to float only 100-to 300-ton boats or small rafts of timber, may be only 3 feet deep.  Major barge canals generally range from 6 to 9 feet in depth, and some are as much as 10 or 12 feet deep.  These canals can carry 1,350-to 2,000-ton crafts.  Ship canals are 25 feet or more deep and are capable of accommodating large vessels in the seagoing class.

    Canals may also be classified as either water-level or lock canals.  Waterlevel canals do not vary in height along their courses.  The best known of these is the Suez Canal, which is at sea level.  Lock canals, which include most modern waterways, contain locks, or special devices for raising and lowering boats along their courses by changing the depth of the water.  Each lock is a stretch of water enclosed by gates at each end.  After a boat enters the lock, water is let in or drained out until it reaches approximately the same level as the water ahead.
