Wādī
Wadi ( ar, وَادِي, wādī), alternatively ''wād'' ( ar, وَاد), North African Arabic Oued, is the Arabic term traditionally referring to a valley. In some instances, it may refer to a wet (ephemeral) riverbed that contains water only when heavy rain occurs. Etymology The term ' is very widely found in Arabic toponyms. Some Spanish toponyms are derived from Andalusian Arabic where ' was used to mean a permanent river, for example: Guadalcanal from ''wādī al-qanāl'' ( ar, وَادِي الْقَنَال, "river of refreshment stalls"), Guadalajara from ''wādī al-ḥijārah'' ( ar, وَادِي الْحِجَارَة, "river of stones"), or Guadalquivir, from ''al-wādī al-kabīr'' ( ar, اَلْوَادِي الْكَبِير, "the great river"). General morphology and processes Wadis are located on gently sloping, nearly flat parts of deserts; commonly they begin on the distal portions of alluvial fans and extend to inland sabkhas or dry lakes.

Guadalquivir
The Guadalquivir (, also , , ) is the fifth-longest river in the Iberian Peninsula and the second-longest river with its entire length in Spain.

Geography The river is long and drains an area of about . It rises at Cañada de las Fuentes (village of Quesada) in the Cazorla mountain range ( Jaén), flows through Córdoba and Seville and reaches the sea at the fishing village of Bonanza, in Sanlúcar de Barrameda, flowing into the Gulf of Cádiz, in the Atlantic Ocean.

Imbrication (sedimentology)
In sedimentology, imbrication is a primary depositional fabric consisting of a preferred orientation of clasts such that they overlap one another in a consistent fashion, rather like a run of toppled dominoes. Imbrication is observed in conglomerates and some volcaniclastic deposits. Types : In conglomerates the shape of many clasts can be approximated to an ellipsoid, with a long axis (A), an intermediate axis (B) and a short axis (C). * ''A-axis imbrication'' where the long axes of the clasts are oriented parallel to the flow direction. This fabric is characteristic of clasts carried in suspension and this is only preserved in the case of a fast-waning flow in which the clasts are deposited without any significant rolling. This fabric is typical of conglomerates at the base of turbidite beds but is also occasionally observed in alluvial fan deposits reworked by flash floods * ''AB-plane imbrication'' where the long axes of the clasts are oriented perpendicular to the flow di ...

Ash-Sharqiyyah Region, Oman
Ash-Sharqiyyah Region ( ar, ٱلْمِنْطَقَة ٱلشَّرْقِيَّة, Al-Minṭaqah Ash-Sharqiyyah, lit=The Eastern Region) was the eastern '' minṭaqah'' (region) of the Sultanate of Oman. The capital of Ash-Sharqiyyah is Sur. On 28 October 2011 Ash Sharqiyah Region was split into Ash Sharqiyah North Governorate and Ash Sharqiyah South Governorate.

Wadi Bani Khalid
''Wilāyat Wādī Banī Khālid'' ( ar, وِلَايَة وَادِي بَنِي خَالِد) is a '' Wilāyah'' (Province) in the Northern Governorate of the Eastern Region of Oman. Located about from Muscat, and from Sur, the province has a wadi which serves as a destination for tourists, that is ''Wādī Banī Khālid'' ( ar, وَادِي بَنِي خَالِد). The wadi Wadi Bani Khalid is one of the best-known wadis in the Sultanate of Oman. Its stream maintains a constant flow of water throughout the year. Large pools of water and boulders are scattered along the course of the wadi. As a geographical area, the wadi covers a large swathe of lowland and the Hajar Mountains. ''Kuhūf'' form some of the features of this wadi. These include ''Kahf Maqal'' (), which was described as an "underground chamber" of the Sultanate of Oman, or the ''akthar'' (, 'best') out of 4,000 caves. '' Aflāj'' (underground canals) or ''ʿUyūn'' are also common in this wadi, including '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eolianite
Eolianite or aeolianite is any rock formed by the lithification of sediment deposited by aeolian processes; that is, the wind. In common use, however, the term refers specifically to the most common form of eolianite: coastal limestone consisting of carbonate sediment of shallow marine biogenic origin, formed into coastal dunes by the wind, and subsequently lithified.

Description Sayles coined the term in 1931, when he described the dune-shaped hills of Bermuda, consisting of bioclastic grainstones. Thus, Bermuda is considered the type locality for carbonate eolianite facies, with clearly defined cross-bedding, foresets, and topsets. Deposition ...

Velocity
Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time (e.g. northbound). Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies. Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called , being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s−1). For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector. If there is a change in speed, direction or both, then the object is said to be undergoing an ''acceleration''. Constant velocity vs acceleration To have a ''constant velocity'', an object must have a constant speed in a constant direction. Constant direction cons ...

Transhumance
Transhumance is a type of pastoralism or nomadism, a seasonal movement of livestock between fixed summer and winter pastures. In montane regions (''vertical transhumance''), it implies movement between higher pastures in summer and lower valleys in winter. Herders have a permanent home, typically in valleys. Generally only the herds travel, with a certain number of people necessary to tend them, while the main population stays at the base. In contrast, ''horizontal transhumance'' is more susceptible to being disrupted by climatic, economic, or political change. Traditional or fixed transhumance has occurred throughout the inhabited world, particularly Europe and western Asia. It is often important to pastoralist societies, as the dairy products of transhumance flocks and herds (milk, butter, yogurt and cheese) may form much of the diet of such populations. In many languages there are words for the higher summer pastures, and frequently these words have been used as place names ...
