Seoul-Incheon Canal
The Ara Canal or Gyeongin Ara Waterway (Hangul: ) is a canal in South Korea linking the Han River to the Yellow Sea. It extends from the Seo-gu district in Incheon to the Gangseo-gu district in Seoul. The canal was built to control flooding, improve shipping logistics, and provide recreational opportunities. History During the Goryeo period, Choe I, the son of Choe Chung-heon, attempted to construct a canal close to the present-day canal site, but the project was not technologically feasible. One of the kings of the Joseon dynasty also attempted to construct the canal, but he was also unsuccessful. The modern "Gulpocheon River Waterproof Road" project began in 1992 and sought to address issues with irregular flows and flooding, such as a flood in the summer of 1987 which affected approximately 6,000 residents of the Incheon area. To address the issue, a project to floodproof the river was undertaken, starting with a five-year survey. In 1995, several scenarios for the ...

Cost–benefit Analysis
Cost–benefit analysis (CBA), sometimes also called benefit–cost analysis, is a systematic approach to estimating the strengths and weaknesses of alternatives. It is used to determine options which provide the best approach to achieving benefits while preserving savings in, for example, transactions, activities, and functional business requirements. A CBA may be used to compare completed or potential courses of action, and to estimate or evaluate the value against the cost of a decision, project, or policy. It is commonly used to evaluate business or policy decisions (particularly public policy), commercial transactions, and project investments. For example, the U.S. Securities and Exchange Commission must conduct cost-benefit analyses before instituting regulations or deregulations. CBA has two main applications: # To determine if an investment (or decision) is sound, ascertaining if – and by how much – its benefits outweigh its costs. # To provide a basis for comparing inve ...

Water Transport In South Korea
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 ab ...

Canals Opened In 2012
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a ''navigation canal'' when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Canal. Many c ...

Marina Port
A marina (from Spanish language, Spanish , Portuguese language, Portuguese and Italian language, Italian : ''marina'', "coast" or "shore") is a Dock (maritime), dock or basin with moorings and supplies for yachts and small boats. A marina differs from a port in that a marina does not handle large passenger ships or cargo from freighters. The word ''marina'' may also refer to an inland wharf on a river or canal that is used exclusively by non-industrial pleasure craft such as canal narrowboats. Emplacement Marinas may be located along the banks of rivers connecting to lakes or seas and may be inland. They are also located on coastal harbors (natural or man made) or coastal lagoons, either as stand alone facilities or within a port complex. History In the 19th century, the few existing pleasure craft shared the same facilities as merchant ship, trading and fishing vessels. The marina appeared in the 20th century with the popularization of yachting. Facilities and services A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
