List Of River Systems By Length
This is a list of the longest rivers on Earth. It includes river systems over in length. Definition of length There are many factors, such as the identification of the source, the identification or the definition of the mouth, and the scale of measurement of the river length between source and mouth, that determine the precise meaning of "river length". As a result, the length measurements of many rivers are only approximations (see also coastline paradox). In particular, there seems to exist disagreement as to whether the Nile or the Amazon is the world's longest river. The Nile has traditionally been considered longer, but in 2007 and 2008 some scientists claimed that the Amazon is longerAmazon Longer Than Nile River, Scientists Say [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mediterranean Sea
The Mediterranean Sea ( ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccation, desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The sea was an important ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rukarara River
The Rukarara River (or Lukarara) is a river in western Rwanda that is a tributary of the Mwogo River, in turn a tributary of the Nyabarongo River. It is the most distant headwater of the Nile. Sources The Rukarara rises in forested country in southern Rwanda to the east of the Congo-Nile Divide. The Kamiranzovu Swamp in the Nyungwe Forest Reserve provides a natural reservoir for the Rukarara. The source of the Rukarara is now known to be the overall source of the Nile The Nile (also known as the Nile River or River Nile) is a major north-flowing river in northeastern Africa.

Mwogo River
The Mwogo River is a river in western Rwanda that is a tributary of the Nyabarongo River. Course The Mwogo rises in forested country in southern Rwanda to the east of the Congo-Nile Divide. It has its sources in the Kitabi sector of the Nyamagabe District. It runs eastward past Nyarusiza into the Huye District. It runs in a northeast direction through the western part of this district, entering the Nyanza district. In Nyanza district it runs northeast, passing Mweya at the point where the Gihimbi River enters it from the left. Below this point it is joined by the Rukarara River The Rukarara River (or Lukarara) is a river in western Rwanda that is a tributary of the Mwogo River, in turn a tributary of the Nyabarongo River.

Nyabarongo River
The Nyabarongo (or Nyawarungu) is a major river in Rwanda, part of the upper headwaters of the Nile. With a total length of , it is the longest river entirely in Rwanda. It is extended in Lake Rweru including a upper course of Kagera River before joining into Ruvuvu River to form the Kagera River. The river begins its course at the confluence of the rivers Mbirurume and Mwogo in the South West of the country. These two rivers themselves begin in Nyungwe Forest, and are considered by some to be the most distant source of the Nile. From its start, Nyabarongo flows northward for 85 km (53 miles), and forms the border between the Western and Southern Provinces. At the confluence with the river Mukungwa, the river changes course and flows eastward for 12 km (7.5 miles), then to a more South Eastern course for the last 200 km (124 miles). For the longest stretch of this course, the river serves as the boundary between the Northern and Southern Provinces, then between ...

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] |
White Nile
The White Nile ( ') is a river in Africa, the minor of the two main tributaries of the Nile, the larger being the Blue Nile. The name "White" comes from the clay sediment carried in the water that changes the water to a pale color. In the strict meaning, "White Nile" refers to the river formed at Lake No, at the confluence of the Bahr al Jabal and Bahr el Ghazal Rivers. In the wider sense, "White Nile" refers to all the stretches of river draining from Lake Victoria through to the merger with the Blue Nile: the "Victoria Nile" from Lake Victoria via Lake Kyoga to Lake Albert, then the "Albert Nile" to the South Sudan border, and then the "Mountain Nile" or "Bahr-al-Jabal" down to Lake No. "White Nile" may sometimes include the headwaters of Lake Victoria, the most remote of which being from the Blue Nile. The 19th-century search by Europeans for the source of the Nile was mainly focused on the White Nile, which disappeared into the depths of what was then known as "Darkest ...

Country
A country is a distinct part of the world, such as a state, nation, or other political entity. When referring to a specific polity, the term "country" may refer to a sovereign state, state with limited recognition, constituent country, or dependent territory. Most sovereign states, but not all countries, are members of the United Nations. There is no universal agreement on the number of "countries" in the world, since several states have disputed sovereignty status or limited recognition, and a number of non-sovereign entities are commonly considered countries. The definition and usage of the word "country" are flexible and have changed over time. '' The Economist'' wrote in 2010 that "any attempt to find a clear definition of a country soon runs into a thicket of exceptions and anomalies." Areas much smaller than a political entity may be referred to as a "country", such as the West Country in England, "big sky country" (used in various contexts of the American We ...

Discharge (hydrology)
In hydrology, discharge is the volumetric flow rate (volume per time, in units of m3/h or ft3/h) of a stream. It equals the product of average flow velocity (with dimension of length per time, in m/h or ft/h) and the cross-sectional area (in m2 or ft2). It includes any suspended solids (e.g. sediment), dissolved chemicals like (aq), or biologic material (e.g. diatoms) in addition to the water itself. Terms may vary between disciplines. For example, a fluvial hydrologist studying natural river systems may define discharge as streamflow, whereas an engineer operating a reservoir system may equate it with outflow, contrasted with inflow. Formulation A discharge is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass. Thus the water discharge of a tap (faucet) can be measured with a measuring jug and a stopwatch. Here the discharge might be 1 litre per 15 seconds, equivalent to 67 ml/second or 4 litres/minute. This is an average meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Area
A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, " watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation, a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin, rather than flowing to the ocean, water converges toward the interio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
