How many locks have been constructed on the panama canal?
The "Locks" are long narrow chambers with gates at each end that lock the water in. A ship goes into a chamber, the gates are closed and water is pumped in or out to raise or lower the ship to a new level. The Panama Canal has three sets of Locks. The Gatun locks are on the Caribbean side. Ships go into the locks at sea level. The gate is closed. Water is pumped in and the ship rises to the level of Lake Gatun. The ship sails across the lake and the canal and enters the Pedro Miguel Locks where it is raised again. It sails across the canal and enters the Miraflores locks where it is lowered to the Pacific Ocean's sea level. Reference: ADDED: It is not usual to pump water uphill on a canal, and it is never pumped downhill. That's what gravity's for! Normally a canal above sea-level is designed not to need no pumping because it can be kept topped up from streams flowing off land higher than its highest reaches; though if these natural sources are reduced or lost then pumping would be necessary. The problem facing the Panama Canal is of the highland streams being reduced by land use such as deforesting.
Is the Suez Canal the only canal without canal locks?
No. Most, but not all, other canals have canal locks. Most canals are not built on flat land. Another without locks is the Corinth Canal.
Is the Suez Canal the largest Canal?
Yes, and as a full-scale Ship canal- not something for narrow-gauge ( in comparison) Barges, such as the Erie Canal and others which used draft animals- often Mules- Draft animals in both senses ( ask the Army?) The Suez canal does not have locks- it did= may still have movable bridges for personnel to access the gates- and for traffic control ( like toll gates on turnpikes) but in operation, ships run under their own power- a Canal Pilot has the Conn- giving the steering orders- and so it goes- no locks needed as it is a sea-level canal.
