Debouch
In hydrology, a debouch (or debouche) is a place where runoff from a small, confined space discharges into a larger, broader body of water. The word is derived from the French verb ''déboucher'' (), which means "to unblock, to clear". The term also has a military usage. Geology In fluvial geomorphology, a debouch is a place where runoff from a small, confined space emerges into a larger, broader space. Common examples are when a stream runs into a river or when a river runs into an ocean. Debouching can generate massive amounts of sediment transport. When a narrow stream travels down a mountain pass into a basin, an alluvial fan will form from the mass deposit of the sediment. The four largest rivers (the Amazon, the Ganges, the Yangtze and the Yellow) are responsible for 20% of the global discharge of sediment in to the oceans by debouches. Geography In fluvial geography, a debouch is a place where a body of water pours forth from a narrow opening. Some examples are: where a ...

Ganges
The Ganges ( ; in India: Ganga, ; in Bangladesh: Padma, ). "The Ganges Basin, known in India as the Ganga and in Bangladesh as the Padma, is an international which goes through India, Bangladesh, Nepal and China." is a trans-boundary river of Asia which flows through India and Bangladesh. The river rises in the western Himalayas in the States and union territories of India, Indian state of Uttarakhand. It flows south and east through the Gangetic Plain, Gangetic plain of North India, receiving the right-bank tributary, the Yamuna, which also rises in the western Indian Himalayas, and several left-bank tributaries from Nepal that account for the bulk of its flow. In West Bengal state, India, a feeder canal taking off from its right bank diverts 50% of its flow southwards, artificially connecting it to the Hooghly River. The Ganges continues into Bangladesh, its name changing to the Padma River, Padma. It is then joined by the Jamuna River (Bangladesh), Jamuna, the lower str ...

Defile (geography)
In geography, a defile is a narrow pass or gorge between mountains or hills. The term originates from a military description of a route through which troops can march only in a narrow column or with a narrow front. On emerging from a defile (or something similar) into open country, soldiers are said to " debouch". Background In a traditional military formation, soldiers march in ranks (the depth of the formation is the number of ranks) and files (the width of the formation is the number of files), so, if a column of soldiers approaches a narrow pass, the formation must narrow, and so the files on the outside must be ordered to the rear (or to some other position) so that the column has fewer files and more ranks. The French verb for this order is ''défiler'', from which the English verb comes, as does the physical description for a valley that forces this manoeuvre. Defiles of military significance can also be formed by other physical features that flank a pass or path and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iss016e019375
The International Space Station (ISS) is a large space station that was assembled and is maintained in low Earth orbit by a collaboration of five space agencies and their contractors: NASA (United States), Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada). As the largest space station ever constructed, it primarily serves as a platform for conducting scientific experiments in microgravity and studying the space environment. The station is divided into two main sections: the Russian Orbital Segment (ROS), developed by Roscosmos, and the US Orbital Segment (USOS), built by NASA, ESA, JAXA, and CSA. A striking feature of the ISS is the Integrated Truss Structure, which connect the station’s vast system of solar panels and radiators to its pressurized modules. These modules support diverse functions, including scientific research, crew habitation, storage, spacecraft control, and airlock operations. The ISS has eight docking and berthing ports for visiting s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landform
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland ...

Rivers
A river is a natural stream of fresh water that flows on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their banks and flood the surrounding area, spreading nutrients to the surrounding area. Sediment or alluvium carried by rivers shapes the landscap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Region Of Freshwater Influence
Region of Freshwater Influence (ROFI) is a region in coastal sea where stratification is governed by the local input of freshwater discharge from the coastal source, while the role of the seasonal input of buoyancy from atmospheric heating is much smaller. Background ROFI and river plume are similar terms related to water masses formed as a result of mixing of river discharge and sea water. The difference between river plumes and ROFI's consists in their spatial scales and freshwater residence time. River plumes are regarded as water masses formed as a result of transformation of freshwater discharge in coastal sea on diurnal to synoptic time scales, while ROFI’s reproduce transformation of freshwater discharge on seasonal to annual time scales. A river plume embedded into a ROFI reproduce a continuous process of transformation of freshwater discharge. Initially, river discharge enters the shelf sea from a river mouth and forms a sub-mesoscale (with spatial extents ~1-10 km) or ...

Fluvial Landforms Of Streams
A stream is a continuous body of water, body of surface water Current (stream), flowing within the stream bed, bed and bank (geography), banks of a channel (geography), 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 river, 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), daylighting (streams), daylighted subterranean river, subterranean water, and surfaced groundwater (Spring (hydrology), 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 pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fortification
A fortification (also called a fort, fortress, fastness, or stronghold) is a military construction designed for the defense of territories in warfare, and is used to establish rule in a region during peacetime. The term is derived from Latin ("strong") and ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley Civilization were the first small cities to be fortified. In ancient Greece, large cyclopean stone walls fitted without mortar had been built in Mycenaean Greece, such as the ancient site of Mycenae. A Greek ''Towns of ancient Greece#Military settlements, phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the ancient Roman, Roman castellum or fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. Militaries are typically authorized and maintained by a sovereign state, with their members identifiable by a distinct military uniform. They may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of a military is usually defined as defence of their state and its interests against external armed threats. In broad usage, the terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police. Beyond warfare, the military may be employed in additional sanctioned and non-sanctioned functions within the state, including internal security threats, crowd control, promotion of political agendas, emergency services and reconstruct ...
