Panama Canal
The Panama Canal () is an artificial waterway in Panama that connects the Caribbean Sea with the Pacific Ocean. It cuts across the narrowest point of the Isthmus of Panama, and is a Channel (geography), conduit for maritime trade between the Atlantic and Pacific Oceans. Lock (water navigation), Locks at each end lift ships up to Gatun Lake, an artificial fresh water lake Above mean sea level, above sea level, created by damming the Chagres River and Lake Alajuela to reduce the amount of excavation work required for the canal. Locks then lower the ships at the other end. An average of of fresh water is used in a single passing of a ship. The canal is threatened by low water levels during droughts. The Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous route around the southernmost tip of South America via the Drake Passage, the Strait of Magellan or the Beagle Channel.

Panama Canal Expansion Project
The Panama Canal expansion project (), also called the Third Set of Locks Project, doubled the capacity of the Panama Canal by adding a new traffic lane, enabling more ships to transit the waterway, and increasing the width and depth of the lanes and locks, allowing larger ships to pass. The new ships, called New Panamax, are about one and a half times larger than the previous Panamax size and can carry over twice as much cargo. The expanded canal began commercial operation on 26 June 2016. The project has: * Built two new sets of locks, one each on the Atlantic and Pacific sides, and excavated new channels to the new locks * Widened and deepened existing channels * Raised the maximum operating water level of Gatun Lake''Proposal for the E ...

Gatun Lake
Gatun Lake () is a mostly freshwater (slightly saline near the locks) reservoir to the south of Colón, Panama. At approximately above sea level, it forms a major part of the Panama Canal, carrying ships of their transit across the Isthmus of Panama. It was created June 27, 1913 when the gates of the spillway at Gatun Dam were closed. The water level was about above sea level and was expected to fill to operating levels in the next six months. Construction Created in 1913 by damming the Chagres River, Gatun Lake is a key part of the Panama Canal, providing the millions of litres of water necessary to operate its locks each time a ship passes through. When constructed, Gatun Lake was the largest artificial lake in the world. The impassable rainforest around the lake has been the best defense of the Panama Canal. Today these areas remain practically unscathed by human interference and are one of the few accessible areas where various native Central American animal and plant spe ...

Armand Reclus
Armand Reclus (13 March 1843 – 9 January 1927) was a French naval engineer and geographer, known for his involvement in the development of the Panama Canal. He graduated top of his class in the Imperial Naval College in 1862, and went on to take part in campaigns in the Pacific and in French colonial actions in Indochina. Like his brothers, Élisée, Élie, Onésime, and Paul Reclus, Armand was a geographer and took part in the 1876–1878 exploration of the Darien with Ferdinand de Lesseps. The route for the Panama Canal that he proposed was adopted by the International Geography Congress in 1879, and he directed the drilling site as the project began. However, he resigned in 1882 after realising the scale of the challenge. After leaving the French navy, he owned vineyards in France and Tunisia where he spent his time. He returned to France in 1911, and died in 1927 – the last of the Reclus brothers. Biography Elie Armand Ebenhezer Reclus was born at Orthez on March 13, 1 ...

Chagres River
The Chagres River (), in central Panama, is the largest river in the Panama Canal's drainage basin. The river is dammed twice, and the resulting reservoirs—Gatun Lake and Lake Alajuela—form an integral part of the canal and its water system. Although the river's natural course runs northwest to its mouth at the Caribbean Sea, its waters also flow, via the Panama Canal locks, canal's locks, into the Gulf of Panama to the south. The Chagres thus has the unusual claim of River bifurcation, drainage into two oceans. Upper Chagres River to Madden Dam The upper Chagres River, its drainage basin, and the drainage basin of several tributaries lie within the Chagres National Park, created in 1985 to preserve the habitat and flow of water into the canal. The terrain of the upper Chagres drainage basin is rugged, with its mountain slopes exceeding 45 degrees in 90 percent of its territory. Some 98 percent of the park consists of old-growth tropical forest. The upper Chagres an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panamax
Panamax and New Panamax (or Neopanamax) are terms for the size limits for ships traveling through the Panama Canal. The limits and requirements are published by the Panama Canal Authority (ACP) in a publication titled "Vessel Requirements". These requirements also describe topics like exceptional dry seasonal limits, propulsion, communications, and detailed ship design. The allowable size is limited by the width and length of the available lock chambers, by the depth of water in the canal, and by the height of the Bridge of the Americas since that bridge's construction, along with the clearance under the Atlantic and Centennial Bridges since their constructions in 2019 and 2004 respectively. These dimensions give clear parameters for ships destined to traverse the Panama Canal and have influenced the design of cargo ships, naval vessels, and passenger ships. Panamax specifications have been in effect since the opening of the canal in 1914. In 2009, the ACP published the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torrijos–Carter Treaties
The Torrijos–Carter Treaties () are two treaties signed by the United States and Panama in Washington, D.C., on September 7, 1977, which superseded the Hay–Bunau-Varilla Treaty of 1903. The treaties guaranteed that Panama would gain control of the Panama Canal after 1999, ending the control of the canal that the U.S. had exercised since 1903. The treaties are named after the two signatories, U.S. President Jimmy Carter and the Commander of Panama's National Guard, General Omar Torrijos. This first treaty is officially titled The Treaty Concerning the Permanent Neutrality and Operation of the Panama Canal () and is commonly known as the "Neutrality Treaty". Under this treaty, the U.S. retained the permanent right to defend the canal from any threat that might interfere with its continued neutral service to ships of all nations. The second treaty is titled The Panama Canal Treaty (''Tratado del Canal de Panamá''), and provided that as from 12:00 on December 31, 1999, Panam ...

Panama Canal Zone
The Panama Canal Zone (), also known as just the Canal Zone, was a International zone#Concessions, concession of the United States located in the Isthmus of Panama that existed from 1903 to 1979. It consisted of the Panama Canal and an area generally extending on each side of the centerline, but excluding Panama City and Colón, Panama, Colón. Its capital was Balboa, Panama, Balboa. The Panama Canal Zone was created on November 18, 1903, from the Separation of Panama from Colombia, territory of Panama; it was established with the signing of the Hay–Bunau-Varilla Treaty, which allowed for the construction of the Panama Canal within the territory by the United States. The zone existed until October 1, 1979, when it was incorporated back into Panama. In 1904, the Isthmian Canal Commission, Isthmian Canal Convention was proclaimed. In it, the Republic of Panama granted to the United States in perpetuity the use, occupation, and control of a zone of land and land underwater for ...

Mortality Rate
Mortality rate, or death rate, is a measure of the number of deaths (in general, or due to a specific cause) in a particular Statistical population, population, scaled to the size of that population, per unit of time. Mortality rate is typically expressed in units of deaths per 1,000 individuals per year; thus, a mortality rate of 9.5 (out of 1,000) in a population of 1,000 would mean 9.5 deaths per year in that entire population, or 0.95% out of the total. It is distinct from "morbidity", which is either the prevalence or Incidence (epidemiology), incidence of a disease, and also from the incidence rate (the number of newly appearing cases of the disease per unit of time). An important specific mortality rate measure is the crude death rate, which looks at mortality from all causes in a given time interval for a given population. , for instance, the Central Intelligence Agency, CIA estimates that the crude death rate globally will be 7.7 deaths per 1,000 people in a population p ...
