Quabbin Aqueduct
The Quabbin Aqueduct carries water from the Quabbin Reservoir to the Wachusett Reservoir. It is part of the Eastern Massachusetts public water supply system, maintained by the Massachusetts Water Resources Authority (MWRA). At in length, it is one of the longest aqueduct tunnels in the world being mile (0.8 km) shorter than the Hetch Hetchy Aqueduct. Physical characteristics Water from the capacity Quabbin Reservoir flows through the Quabbin Aqueduct from the northeast side of the Quabbin, up a slope to the Ware River Diversion in South Barre, Massachusetts, down again to the Wachusett Reservoir, and then through a power station near the Oakdale section of West Boylston, Massachusetts. This upward and downward flow occurs by natural siphon action, with the high point in the siphon being at the Ware River Diversion. The water surface at the Quabbin Reservoir is about 524 feet (159.7 m) above Mean Sea Level (MSL). The water surface at the Wachusett Reservoir is about 384 ...

Barre, Massachusetts
Barre ( ) is a town in Worcester County, Massachusetts, United States. The population was 5,530 at the 2020 census. History Originally called the Northwest District of Rutland, it was first settled by Europeans in 1720. The town was incorporated as a district on June 17, 1774, as Hutchinson after Thomas Hutchinson, colonial governor of Massachusetts. Eventually, along with 41 other districts in the state, they were all incorporated on August 23, 1775 by the Massachusetts Court. The next year on November 7, 1776, it was renamed Barre in honor of Colonel Isaac Barré, an Irish-born MP who was a champion of American Independence. Starting in the 1800s, the Boston, Barre and Gardner Railroad provided rail service to the town. "This township was originally known as Rutland, West District; but prior to 1770 its name was changed to "Hutchinson", in honor of the Hon. Thomas Hutchinson who was Lieutenant Governor of Massachusetts in 1765, became acting Governor in 1769, and Governo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Level
Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead the midpoint between a mean low and mean high tide at a particular location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. Current sea level rise is mainly caused by human-induced climate change. When temperatures rise, Glacier, mountain glaciers and the Ice sheet, polar ice caps melt, increasing the amount of water in water bodies. Because most of human settlem ...

Transportation Buildings And Structures In Worcester County, Massachusetts
Transport (in British English), or transportation (in American English), is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land (rail and road), water, cable, pipeline, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations. Transport infrastructure consists of both fixed installations, including roads, railways, airways, waterways, canals, and pipelines, and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations), and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance. Means of transport are any of the different kinds of transport facilities used to carry people or cargo. They may include vehicles, riding animals, and pack animals. Vehicles may inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunnels In Massachusetts
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] |
