Wei River
The Wei River () is a major river in west-central China's Gansu and Shaanxi provinces.

Town Center
A town centre is the commercial or geographical centre or core area of a town. Town centres are traditionally associated with shopping or retail. They are also the centre of communications with major public transport hubs such as train or bus stations. Public buildings including town halls, museums and libraries are often found in town centres. Town centres are symbolic to settlements as a whole and often contain the best examples of architecture, main landmark buildings, statues and public spaces associated with a place. Canada In some areas of Canada, particularly large, urban areas, town centres refer to alternate commercial areas to the city's downtown. These centres are usually located within a large neighbourhood and characterized by medium-high density commercial and residential property; such as Brentwood and Lougheed Town Centres in Burnaby. Philippines United Kingdom The first example in the UK of a purposely planned commercial or town centre is Newcastle's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ordos Loop
The Ordos Plateau, also known as the Ordos Basin or simply the Ordos, is a highland sedimentary basin in parts of most Northern China with an elevation of , and consisting mostly of land enclosed by the Ordos Loop, a large northerly rectangular bend of the Yellow River. It is China's second largest sedimentary basin (after the Tarim Basin) with a total area of , and includes territories from five provinces, namely Shaanxi, Gansu, Ningxia, Inner Mongolia and a thin fringe of Shanxi (western border counties of Xinzhou, Lüliang and Linfen), but is demographically dominated by the former three, hence is also called the Shaan-Gan-Ning Basin. The basin is bounded in the east by the Lüliang Mountains, north by the Yin Mountains, west by the Helan Mountains, and south by the Huanglong Mountains, Meridian Ridge and Liupan Mountains. The name "Ordos" ( Mongolian: ) comes from the '' orda'', which originally means "palaces" or "court" in Old Turkic. The seventh largest prefectu ...

Confluence
In geography, a confluence (also ''conflux'') occurs where two or more watercourses join to form a single channel (geography), channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river (main stem); or where two streams meet to become the river source, source of a river of a new name (such as the confluence of the Monongahela River, Monongahela and Allegheny River, Allegheny rivers, forming the Ohio River); or where two separated channels of a river (forming a river island) rejoin downstream from their point of separation. Scientific study Confluences are studied in a variety of sciences. Hydrology studies the characteristic flow patterns of confluences and how they give rise to patterns of erosion, bars, and scour pools. The water flows and their consequences are often studied with mathematical models. Confluences are relevant to the distribution of living organisms (i.e., ecology) as well; "the general pattern [downstream o ...

Mainstem (hydrology)
In hydrology, a main stem or mainstem (also known as a trunk) is "the primary downstream segment of a river, as contrasted to its tributaries". The mainstem extends all the way from one specific headwater to the outlet of the river, although there are multiple ways to determine which headwater (or first-order tributary) is the source of the main stem. Water enters the main stem from the river's drainage basin, the land area through which the mainstem and its tributaries flow.. A drainage basin may also be referred to as a ''watershed'' or ''catchment''. Hydrological classification systems assign numbers to tributaries and mainstems within a drainage basin. In the Strahler number, a modification of a system devised by Robert E. Horton in 1945, channels with no tributaries are called "first-order" streams. When two first-order streams meet, they are said to form a second-order stream; when two second-order streams meet, they form a third-order stream, and so on. In the Horton sy ...

River Source
The headwater of a river or stream is the geographical point of its beginning, specifically where surface runoff water begins to accumulate into a flowing channel of water. A river or stream into which one or many tributary rivers or streams flows has many headwaters, these being all of the individual headwaters of its tributaries. Each headwater is one of the river or stream's sources, as it is the place where surface runoffs from rainwater, meltwater, or spring water begin accumulating into a more substantial and consistent flow that becomes a Strahler number, first-order tributary of that river or stream. The tributary with the longest channel (geography), channel of all the tributaries to a river or stream, such length measured from that tributary's headwater to its mouth where it discharges into the river or stream, is the main stem of the river or stream in question. Definition The United States Geological Survey (USGS) states that a river's "length may be considered to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
