In geography, a plain is a flat, sweeping landmass that generally does not change much in elevation. Plains occur as lowlands along the bottoms of valleys or on the doorsteps of mountains, as coastal plains, and as plateaus or uplands.
A floodplain or flood plain is an area of land adjacent to a stream or river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge. The soils usually consist of levees, silts, and sands deposited during floods. Levees are the heaviest materials and they are deposited first; silts and sands are finer materials.
Alluvial fans are triangular-shaped deposits of water-transported material, often referred to as alluvium. They are an example of an unconsolidated sedimentary deposit and tend to be larger and more prominent in arid to semi-arid regions. These alluvial fans typically form in elevated or even mountainous regions where there is a rapid change in slope from a high to low gradient. The river or stream carrying the sediment flows at a relatively high velocity due to the high slope angle, which is why coarse material is able to remain in the flow. When the slope decreases rapidly into a relatively planar area or plateau, the stream loses the energy it needs to move its sediment. Deposition subsequently occurs and the sediment ultimately spreads out, creating an alluvial fan. Three primary zones occur within an alluvial fan which includes the proximal fan, medial fan, and the distal fan.
The Victorian gold rush was a period in the history of Victoria, Australia approximately between 1851 and the late 1860s. It led to a period of extreme prosperity for the Australian colony, and an influx of population growth and financial capital for Melbourne, which was dubbed "Marvellous Melbourne" as a result of the procurement of wealth.
Conglomerate is a coarse-grained clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts, e.g., granules, pebbles, cobbles, and boulders, larger than 2 mm (0.079 in) in diameter. Conglomerates form by the consolidation and lithification of gravel. Conglomerates typically contain finer grained sediment, e.g., either sand, silt, clay or combination of them, called matrix by geologists, filling their interstices and are often cemented by calcium carbonate, iron oxide, silica, or hardened clay.
The Mahananda River is a trans-boundary river that flows through the Indian states of West Bengal and Bihar, and Bangladesh.
Bogra District, officially known as Bogura District, is a northern district of Bangladesh, in the Rajshahi Division. It is called the gateway to North Bengal. Bogra is an industrial city where many small and mid-sized industries are sited. Bogra district was a part of the ancient Pundravardhana territory and the ruins of Mahasthangarh, the ancient capital of Pundravardhana, are located north of Bogra.
Eboli is a town and comune of Campania, southern Italy, in the province of Salerno, on the south edge of the hills overlooking the valley of the Sele.
Foothills or piedmont are geographically defined as gradual increases in elevation at the base of a mountain range, higher hill range or an upland area. They are a transition zone between plains and low relief hills and the adjacent topographically higher mountains, hills, and uplands. Frequently foothills consist of alluvial fans, coalesced alluvial fans and dissected plateaus.
Upland and lowland are conditional descriptions of a plain based on elevation above sea level. In studies of the ecology of freshwater rivers, habitats are classified as upland or lowland.
Cottingley is a suburban village within the City of Bradford in West Yorkshire, England, situated between Shipley and Bingley. It is perhaps best known for the Cottingley Fairies, which appeared in a series of photographs taken there during the early 20th century.
Kotelny Island is part of the Anzhu Islands subgroup of the New Siberian Islands located between the Laptev Sea and the East Siberian Sea in the Russian Arctic. It is administratively and municipally part of Bulunsky District.
Rocky River is a locality in northern New South Wales, Australia near the town of Uralla on the Northern Tablelands plateau.
Herbsheim is a commune in the Bas-Rhin department in Grand Est in north-eastern France.
Hushing is an ancient and historic mining method using a flood or torrent of water to reveal mineral veins. The method was applied in several ways, both in prospecting for ores, and for their exploitation. Mineral veins are often hidden below soil and sub-soil, which must be stripped away to discover the ore veins. A flood of water is very effective in moving soil as well as working the ore deposits when combined with other methods such as fire-setting.
Staines Moor is a 510.8-hectare (1,262-acre) biological Site of Special Scientific Interest north of Staines-upon-Thames in Surrey. It is part of South West London Waterbodies Ramsar site and Special Protection Area
An alluvial river is one in which the bed and banks are made up of mobile sediment and/or soil. Alluvial rivers are self-formed, meaning that their channels are shaped by the magnitude and frequency of the floods that they experience, and the ability of these floods to erode, deposit, and transport sediment. For this reason, alluvial rivers can assume a number of forms based on the properties of their banks; the flows they experience; the local riparian ecology; and the amount, size, and type of sediment that they carry.
The Clipper Mountain Wilderness is a wilderness area in the Clipper Mountains of the eastern Mojave Desert and within Mojave Trails National Monument, located in northeastern San Bernardino County, California. It is under the jurisdiction of the Bureau of Land Management.
