Caraulun River
The Caraulun River ( pt, Ribeira Caraulun or , tet, Mota Caraulun or ) is a river in East Timor. It flows for the most part in a southerly direction, forms the southern part of the border between Ainaro and Manufahi municipalities, and discharges into the Timor Sea. Etymology The river's name has its origins in the Tetum expression ''Karau Ulun'', which means buffalo head. The river itself is said to resemble buffalo horns. According to anthropologist Matthew Libbis: Libbis went on to observe that there was another version of the story, involving two brothers, one of whom thrust a spear causing a spring to gush forth from the ground. In that version, the two brothers represented a division between earth and sky, with the older brother belonging in the mountains. Course The headwaters of the river are in the portion of East Timor's central mountains ranging from just to the south of Maubisse in Ainaro municipality to just to the south of Turiscai in Manufahi municipality.

Braided River
A braided river, or braided channel, consists of a network of river channels separated by small, often temporary, islands called braid bars or, in English usage, ''aits'' or ''eyots''. Braided streams tend to occur in rivers with high sediment loads or coarse grain sizes, and in rivers with steeper slopes than typical rivers with straight or meandering channel patterns. They are also associated with rivers with rapid and frequent variation in the amount of water they carry, i.e., with "flashy" rivers, and with rivers with weak banks. Braided channels are found in a variety of environments all over the world, including gravelly mountain streams, sand bed rivers, on alluvial fans, on river deltas, and across depositional plains. Description A braided river consists of a network of multiple shallow channels that diverge and rejoin around ephemeral ''braid bars''. This gives the river a fancied resemblance to the interweaved strands of a braid. The braid bars, also known as channel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liurai
Liurai is a ruler's title on Timor. The word is Tetun and literally means "surpassing the earth". It is originally associated with Wehali, a ritually central kingdom situated at the south coast of Central Timor (now included in Indonesia). The sacral lord of Wehali, the Maromak Oan ("son of God") enjoyed a ritually passive role, and he kept the Liurai as the executive ruler of the land. In the same way, the rulers of two other important princedoms, Sonbai in West Timor and Likusaen ( Liquica) in East Timor, were often referred as Liurais, which indicated a symbolic tripartition of the island. In later history, especially in the nineteenth and twentieth centuries, the term Liurai underwent a process of inflation. By this time it denoted any ruler in the Portuguese part of Timor, great or small. In the Dutch part in West Timor the title appears to have been restricted to the Sonbai and Wehali rulers. The rulers in the west were known by the Malay term raja, while there were interna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diarchy
Diarchy (from Greek , ''di-'', "double", and , ''-arkhía'', "ruled"),Occasionally misspelled ''dyarchy'', as in the ''Encyclopaedia Britannica'' article on the colonial British institution duarchy, or duumvirate (from Latin ', "the office of the two men"). is a form of government characterized by corule, with two people ruling a polity together either lawfully or ''de facto'', by collusion and force. The leaders of such a system are usually known as corulers. Historically, ''diarchy'' particularly referred to the system of shared rule in British India established by the Government of India Acts 1919 and 1935, which devolved some powers to local councils, which had included native Indian representation under the Indian Councils Act 1892. 'Duumvirate' principally referred to the offices of the various duumviri established by the Roman Republic. Both, along with less common synonyms such as biarchy and tandemocracy, are now used more generally to refer to any system of joint ru ...

Drainage Basin
A drainage basin is an area of land where 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 a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Confluence
In geography, a confluence (also: ''conflux'') occurs where two or more flowing bodies of water 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 at Pittsburgh, forming the Ohio); or where two separated channels of a river (forming a river island) rejoin at the downstream end. Scientific study of confluences 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 s ...

Plume (fluid Dynamics)
In hydrodynamics, a plume or a column is a vertical body of one fluid moving through another. Several effects control the motion of the fluid, including momentum (inertia), diffusion and buoyancy (density differences). Pure ''jets'' and pure ''plumes'' define flows that are driven entirely by momentum and buoyancy effects, respectively. Flows between these two limits are usually described as forced plumes or buoyant jets. "Buoyancy is defined as being positive" when, in the absence of other forces or initial motion, the entering fluid would tend to rise. Situations where the density of the plume fluid is greater than its surroundings (i.e. in still conditions, its natural tendency would be to sink), but the flow has sufficient initial momentum to carry it some distance vertically, are described as being negatively buoyant. Movement Usually, as a plume moves away from its source, it widens because of entrainment of the surrounding fluid at its edges. Plume shapes can be influen ...

Wet Season
The wet season (sometimes called the Rainy season) is the time of year when most of a region's average annual rainfall occurs. It is the time of year where the majority of a country's or region's annual precipitation occurs. Generally, the season lasts at least a month. The term ''green season'' is also sometimes used as a euphemism by tourist authorities. Areas with wet seasons are dispersed across portions of the tropics and subtropics. Under the Köppen climate classification, for tropical climates, a wet season month is defined as a month where average precipitation is or more. In contrast to areas with savanna climates and monsoon regimes, Mediterranean climates have wet winters and dry summers. Dry and rainy months are characteristic of tropical seasonal forests: in contrast to tropical rainforests, which do not have dry or wet seasons, since their rainfall is equally distributed throughout the year.Elisabeth M.

Avulsion (river)
In sedimentary geology and fluvial geomorphology, avulsion is the rapid abandonment of a river channel and the formation of a new river channel. Avulsions occur as a result of channel slopes that are much less steep than the slope that the river could travel if it took a new course. Deltaic and net-depositional settings Avulsions are common in river deltas, where sediment deposits as the river enters the ocean and channel gradients are typically very small. This process is also known as delta switching. Deposition from the river results in the formation of an individual deltaic lobe that pushes out into the sea. An example of a deltaic lobe is the bird's-foot delta of the Mississippi River, pictured at right with its sediment plumes. As the deltaic lobe advances, the slope of the river channel becomes lower, as the river channel is longer but has the same change in elevation. As the slope of the river channel decreases, it becomes unstable for two reasons. First, water under the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Laclo River
The North Laclo River ( pt, Ribeira de Lacló do Norte or , tet, Mota Lakló) is the longest river in East Timor. It flows northeast into Wetar Strait, reaching the coast near the city of Manatuto. It has no connection to the South Laclo, which flows into the Timor Sea. Etymology The river takes its name from the town of , which is located on its left bank, about from its mouth. English language sources conventionally refer to the river as the ''North Laclo River'', as there is also another Laclo River, usually referred to in English as the South Laclo River, which discharges into the Timor Sea on the south coast of East Timor. The two rivers are not connected to each other; both rise in the uplands near Turiscai in Manufahi municipality, where a drainage divide causes them to flow northwards and southwards, respectively, in each case later augmented by several tributaries. Course The headwaters of the river are in the portion of East Timor's central mountains ranging from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grade (slope)
The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, stream and river banks and beds are often described as grades, but typically grades are used for human-made surfaces such as roads, landscape grading, roof pitches, railroads, aqueducts, and pedestrian or bicycle routes. The grade may refer to the longitudinal slope or the perpendicular cross slope. Nomenclature There are several ways to express slope: # as an ''angle'' of inc ...
