Civil Engineer
A civil engineer is a person who practices civil engineering – the application of planning, designing, constructing, maintaining, and operating infrastructure while protecting the public and environmental health, as well as improving existing infrastructure that may have been neglected. Civil engineering is one of the oldest engineering disciplines because it deals with constructed environment including planning, designing, and overseeing construction and maintenance of building structures, and facilities, such as roads, railroads, airports, bridges, harbors, channels, dams, irrigation projects, pipelines, power plants, and water and sewage systems. The term "civil engineer" was established by John Smeaton in 1750 to contrast engineers working on civil projects with the military engineers, who worked on armaments and defenses. Over time, various sub-disciplines of civil engineering have become recognized and much of military engineering has been absorbed by civil engineering. ...

Snagboat
A snagboat is a river boat, resembling a barge with superstructure for crew accommodations, and deck-mounted cranes and hoists for removing snags and other obstructions from rivers and other shallow waterways. USA During the American Civil War, when much of the naval fighting was done on rivers and their tributaries, numerous snagboats were in operation. , for example, was a commercial snagboat quickly converted by the Union Army to a river gunboat when the American Civil War broke out. Snagboats of the USA Bear was a wooden-hulled, stern-wheel steamship that served as a snagboat for the United States Army Corps of Engineers. Seizer was a wooden-hulled, stern-wheel steamship that served as the first snagboat for the United States Army Corps of Engineers on the Sacramento River. '' W. T. Preston'' is a specialized sternwheeler that operated as a snagboat, removing log jams and natural debris that prevented river navigation on several Puget Sound-area rivers. She is n ...

Monongahela River
The Monongahela River ( , ), sometimes referred to locally as the Mon (), is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed August 15, 2011 river on the Allegheny Plateau in north-central West Virginia and Southwestern Pennsylvania. The river flows from the confluence of its west and east forks in north-central West Virginia northeasterly into southwestern Pennsylvania, then northerly to Pittsburgh and its confluence with the Allegheny River to form the Ohio River. The river includes a series of locks and dams that makes it navigable. Etymology The Unami word ''Monongahela'' means "falling banks", in reference to the geological instability of the river's banks. Moravian missionary David Zeisberger (1721–1808) gave this account of the naming: "In the Indian tongue the name of this river was ''Mechmenawungihilla'' (alternatively spelled ''Menawngihella''), which signifies a high bank, which is ever washed o ...

Lock (water Navigation)
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a chamber in a permanently fixed position in which the water level can be varied. (In a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson (engineering), caisson) that rises and falls.) Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Over time, more and larger locks have been used in canals to allow a more direct route to be taken. History Ancient Egypt In Ancient Egypt, the river-locks was probably part of the Canal of the Pharaohs: Ptolemy II is credited by some for being the first to solve the problem of keeping the Nile free of salt water when his engineers invented the lock around 274/273 BC. Ancient China During 960–1279 CE, the natural extension o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Towboat
A pusher, pusher craft, pusher boat, pusher tug, or towboat, is a boat designed for pushing barges or car floats. In the United States, the industries that use these vessels refer to them as towboats. These vessels are characterized by a square bow and a shallow draft, and they typically have knees, which are large plates mounted to the bow for pushing barges of various heights. These boats usually operate on rivers and inland waterways. Multiple barges lashed together, or a boat and any barges lashed to it, are referred to as a ''tow'' and can have dozens of barges. Many of these vessels, especially the long-haul boats, include living quarters for the crew. Size Towboat engine outputs range from less than up to . Most towboats are from long, and wide. Smaller boats are used in harbors, fleeting areas and around locks while larger boats operate in "line-haul" operations over long distances and between major ports.
