San Jacinto Tunnel
The San Jacinto tunnel is considered the key link in Colorado River Aqueduct system. The 13 mi (21 km) long, 16 ft (4.9 m) diameter tunnel runs beneath the San Jacinto Mountains between Cabazon, California and Gilman Hot Springs in Riverside County, California. History The $23 million project started on April 8, 1933. Tunnel crews dug from four directions: the two main portals and two shafts. On July 1, 1934, one of the tunnel crews narrowly escaped the tunnel as ground water burst in and began filling the tunnel and shafts at a rate of nearly 8,000 US gallons per minute (0.50 m3/s). Metropolitan Water District of Southern California (MWD) Chief Engineer Frank E. Weymouth had noted in his 1930 report on the tunnel routes that the Parker route “involves less risk than any of the other proposed lines.” The continued intrusion of water was more than the original contractors could handle, and in February 1935 the MWD terminated the contract and took over the job.

Water Tunnels In The United States
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water covers a ...

Tunnels In California
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. Tunne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
