Source (river)
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] |

Perennial Stream
A stream is a continuous body of surface water flowing within the bed and banks of a channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long, large streams are usually called rivers, while smaller, less voluminous and more intermittent streams are known, amongst others, as brook, creek, rivulet, rill, run, tributary, feeder, freshet, narrow river, and streamlet. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighted subterranean water, and surfaced groundwater (spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls. ...

River Churn
The River Churn is a tributary of the River Thames in central England. It rises at Seven Springs, Gloucestershire, Seven Springs in Gloucestershire and flows south for approximately to meet the Thames at Cricklade in Wiltshire. Its length from its source to the Confluence (geography), confluence with the Thames is greater than that of the Thames from Thames Head, but the Churn is regarded as a tributary, rather than the main river. Description The River Churn is the first tributary river of the River Thames. It rises in the Cotswolds at Seven Springs, Gloucestershire, Seven Springs, south of Cheltenham, Gloucestershire, England and flows south across the Cotswold dip slope, passing through North Cerney and Cirencester, and joining the Thames in the parish of Cricklade in Wiltshire. Its length from source to Confluence (geography), confluence with the Thames is considerably greater than that of the Thames from Thames Head, and its flow is also more consistent than the Winterbo ...

River Thames
The River Thames ( ), known alternatively in parts as the The Isis, River Isis, is a river that flows through southern England including London. At , it is the longest river entirely in England and the Longest rivers of the United Kingdom, second-longest in the United Kingdom, after the River Severn. The river rises at Thames Head in Gloucestershire and flows into the North Sea near Tilbury, Essex and Gravesend, Kent, via the Thames Estuary. From the west, it flows through Oxford (where it is sometimes called the Isis), Reading, Berkshire, Reading, Henley-on-Thames and Windsor, Berkshire, Windsor. The Thames also drains the whole of Greater London. The lower Reach (geography), reaches of the river are called the Tideway, derived from its long Tidal river, tidal reach up to Teddington Lock. Its tidal section includes most of its London stretch and has a rise and fall of . From Oxford to the estuary, the Thames drops by . Running through some of the drier parts of mainland Bri ...

Brazilian Institute Of Geography And Statistics
The Brazilian Institute of Geography and Statistics (; IBGE) is the agency responsible for official collection of statistical, geographic, cartographic, geodetic and environmental information in Brazil. IBGE performs a decennial national census; questionnaires account for information such as age, household income, literacy, education, occupation and hygiene levels. IBGE is a public institute created in 1936 under the name ''National Institute of Statistics''. Its founder and chief proponent was statistician Mário Augusto Teixeira de Freitas. The current name dates from 1938. Its headquarters are located in Rio de Janeiro, and its current president is Marcio Pochmann, replacing Eduardo Rios Neto. It was made a federal agency by Decree-Law No. 161 on February 13, 1967, and is linked to the Ministry of the Economy, inside the Secretariat of Planning, Budget and Management. Structure IBGE has a network of national research and dissemination components, comprising: * 27 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kagera River
The Kagera River, also known as Akagera River, or Alexandra Nile, is an East African river, forming part of the upper headwaters of the Nile and carrying water from its most distant source.Stanley, H.M., 1899, Through the Dark Continent, London: G. Newnes, With a total length of from its source located in Lake Rweru in Rwanda. The section of river named Kagera begins in Burundi, flowing out from Lake Rweru. From the lake, it flows east along the Rwanda-Burundi and Rwanda-Tanzania borders to a confluence with the Ruvubu River. The waters of the Kagera are thus provided by two major tributaries, the Nyabarongo of Rwanda, which feeds Lake Rweru, and the Ruvubu of Burundi. It is unknown which of these two feeder rivers is the longer and hence the ultimate source of the Nile. From the confluence, the Kagera flows north along the Rwanda-Tanzania border, over Rusumo Falls and through Akagera National Park. It then takes a turn to the east, following the Tanzania-Uganda border an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Confluence (geography)
In geography, a confluence (also ''conflux'') occurs where two or more watercourses join to form a single 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 source of a river of a new name (such as the confluence of the Monongahela and 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 ownstream of confluencesof increasing stream flow and decreasing slopes driv ...
