IN EARLIER DAYS THEY SAY SAILORS WENT AROUND CAPE HORN THE SOUTHERNMOST TIP OF SOUTH AMERICA TO REACH THE OTHER SIDE OF U.S.A FROM THE EASTERN AND WESTERN COASTS. BUT TODAY THE CROSSING FROM THE ATLANTIC TO THE PACIFIC AND VICEVERSA IS BEING DONE THROUGH THE FAMOUS CANAL OF THE WATERS
The Panama Canal (Spanish: Canal de Panamá) is an 82-kilometre (51 mi) ship canal in Panama that connects the Atlantic Ocean (via the Caribbean Sea) to the Pacific Ocean. The canal cuts across the Isthmus of Panama and is a key conduit for international maritime trade.
Work on the canal, which began in 1880, was completed in 1914, making it no longer necessary for ships to sail the lengthy Cape Horn route around the southernmost tip of South America and to navigate the dangerous waters of the Strait of Magellan. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut made it possible for ships to travel between the Atlantic and Pacific Oceans in half the time previously required. The shorter, faster, safer route to the U.S. West Coast and to nations in and along the Pacific Ocean allowed those places to become more integrated with the world economy.
Ownership of the territory that is now the Panama Canal was first Colombian, then French and then American before coming under the control of the Panamanian government in 1999. The Panama Canal has seen annual traffic rise from about 1,000 ships when it opened in 1914, to 14,702 vessels in 2008, the latter measuring a total of 309.6 million Panama Canal/Universal Measurement System (PC/UMS) tons. By 2008, more than 815,000 vessels had passed through the canal, many of them much larger than the original planners could have envisioned; the largest ships that can transit the canal today are called Panamax.The American Society of Civil Engineers has named the Panama Canal one of the SEVEN WONDERS OF MODERN WORLD..
The history of the Panama Canal goes back to 16th century. After realizing the riches of Peru, Ecuador, and Asia, and counting the time it took the gold to reach the ports of Spain, it was suggested c.1524 to Charles V, that by cutting out a piece of land somewhere in Panama, the trips would be made shorter and the risk of taking the treasures through the isthmus would justify such an enterprise. A survey of the isthmus was ordered and subsequently a working plan for a canal was drawn up in 1529. The wars in Europe and the thirsts for the control of kingdoms in the Mediterranean Sea simply put the project on permanent hold.
In 1534 a Spanish official suggested a canal route close to that of the now present canal. Later, several other plans for a canal were suggested, but no action was taken. The Spanish government subsequently abandoned its interest in the canal.
In the early 19th century the books of the German scientist Alexander von Humboldt revived interest in the project, and in 1819 the Spanish government formally authorized the construction of a canal and the creation of a company to build it. The discovery of gold in California in 1848 and the rush of would-be miners stimulated Americas interest in digging the canal
Time and mileage would be dramatically reduced when travelling from the Atlantic to the Pacific ocean or vice versa. For example, it would save a total of 18,000 miles on a trip from New York to San Francisco.
Although de Lesseps was not an engineer, he was appointed chairman for the construction of the Panama Canal. Upon taking charge, he organized an International Congress to discuss several schemes for constructing a ship canal. De Lesseps opted for a sea-level canal based on the construction of the Suez Canal. He believed that if a sea-level canal worked when constructing the Suez Canal, it must work for the Panama Canal.
While the Pacific Ocean is west of the isthmus and the Atlantic to the east, the direction of the 8- to 10-hour canal passage from the Pacific to the Atlantic is from southeast to northwest. This is because of an anomaly in the shape of the isthmus at the point the canal occupies. The Bridge of the Americas (Spanish: Puente de las Américas) at the Pacific side is about a third of a degree east of the Colón end on the Atlantic side.
The canal consists of artificial lakes, several improved and artificial channels, and three sets of locks. An additional artificial lake, Alajuela Lake (known during the American era as Madden Lake), acts as a reservoir for the canal. The layout of the canal as seen by a ship passing from the Pacific end to the Atlantic is as follows:[33]
From the buoyed entrance channel in the Gulf of Panama (Pacific side), ships travel 13.2 km (8.2 mi) up the channel to the Miraflores locks, passing under the Bridge of the Americas.
The two-stage Miraflores lock system, including the approach wall, is 1.7 km (1.1 mi) long, with a total lift of 16.5 meters (54 ft) at mid-tide.
The artificial Miraflores Lake is the next stage, 1.7 km (1.1 mi) long, and 16.5 meters (54 ft) above sea level.
The single-stage Pedro Miguel lock, which is 1.4 km (0.87 mi) long, is the last part of the ascent with a lift of 9.5 meters (31 ft) up to the main level of the canal.
The Gaillard (Culebra) Cut slices 12.6 km (7.8 mi) through the continental divide at an altitude of 26 meters (85 ft), and passes under the Centennial Bridge.
The Chagres River (Río Chagres), a natural waterway enhanced by the damming of Lake Gatún, runs west about 8.5 km (5.3 mi), merging into Lake Gatun.
Gatun Lake, an artificial lake formed by the building of the Gatun Dam, carries vessels 24.2 km (15.0 mi) across the isthmus.
The Gatún locks, a three-stage flight of locks 1.9 km (1.2 mi) long, drop ships back down to sea level.
A 3.2 km (2.0 mi) channel forms the approach to the locks from the Atlantic side.
Limón Bay (Bahía Limón), a huge natural harbour, provides an anchorage for some ships awaiting passage, and runs 8.7 km (5.4 mi) to the outer breakwater.
Thus, the total length of the canal is 77.1 km (47.9 mi).
What makes the Panama Canal remarkable is its self sufficiency. The dam at Gatun, is able to generate the electricity to run all the motors which operate the canal as well as the locomotives in charge of towing the ships through the canal. No force is required to adjust the water level between the locks except gravity. As the lock operates, the water simply flows into the locks from the lakes or flows out to the sea level channels. The canal also relies on the overabundant rainfall of the area to compensate for the loss of the 52 million gallons of fresh water consumed during each crossing.
Despite the limit in ship size, the canal is still one of the most highly travelled waterways in the world, handling over 12,000 ships per year. The 51-mile crossing takes about nine hours to complete, an immense time saving when compared with rounding the tip of South America.
Until the early 1970's the Panama Canal Company made considerable profits. After a period of
The original plan for the Panama Canal was evolved from many years of engineering study, but it was unfortunate that it had not been based on marine operating experience.

In 1879, de Lesseps proposed a sea level canal through Panama. With the success he had with the construction of the Suez Canal in Egypt just ten years earlier, de Lesseps was confident he would complete the water circle around the world.
Time and mileage would be dramatically reduced when travelling from the Atlantic to the Pacific ocean or vice versa. For example, it would save a total of 18,000 miles on a trip from New York to San Francisco.

While the Pacific Ocean is west of the isthmus and the Atlantic to the east, the direction of the 8- to 10-hour canal passage from the Pacific to the Atlantic is from southeast to northwest. This is because of an anomaly in the shape of the isthmus at the point the canal occupies.

Until the early 1970's the Panama Canal Company made considerable profits. After a period of
nearly 60 years the loss in profit required the increase of tolls 3 times in 4 years. Much of the equipment, some of which dates back too 1914, now requires expensive modifications, simply to continue moving its present rate of traffic.
The original plan for the Panama Canal was evolved from many years of engineering study, but it was unfortunate that it had not been based on marine operating experience.
