Noah appears as the last of the Antediluvian patriarchs in the traditions of Abrahamic religions. His story appears in the Hebrew Bible, the Quran and Baha'i writings, and extracanonically.
A flood is an overflow of water that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding. Examples for human changes are land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees. Global environmental issues also influence causes of floods, namely climate change which causes an intensification of the water cycle and sea level rise. For example, climate change makes extreme weather events more frequent and stronger. This leads to more intense floods and increased flood risk.
A floodplain or flood plain or bottomlands is an area of land adjacent to a river. Floodplains stretch from the banks of a river channel to the base of the enclosing valley, and experience flooding during periods of high discharge. The soils usually consist of clays, silts, sands, and gravels deposited during floods.
The Fraser River is the longest river within British Columbia, Canada, rising at Fraser Pass near Blackrock Mountain in the Rocky Mountains and flowing for 1,375 kilometres (854 mi), into the Strait of Georgia just south of the City of Vancouver. The river's annual discharge at its mouth is 112 cubic kilometres (27 cu mi) or 3,550 cubic metres per second (125,000 cu ft/s), and each year it discharges about 20 million tons of sediment into the ocean.
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower. Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants. However, when constructed in lowland rainforest areas, where part of the forest is inundated, substantial amounts of greenhouse gases may be emitted.
The Saint John River is a 673-kilometre-long (418 mi) river flowing within the Dawnland region from headwaters in the Notre Dame Mountains near the Maine-Quebec border through western New Brunswick to the northwest shore of the Bay of Fundy. Eastern Canada's longest river, its drainage basin is one of the largest on the east coast at about 55,000 square kilometres (21,000 sq mi). This “River of the Good Wave” and its tributary drainage basin formed the territorial countries of the Wolastoqiyik and Passamaquoddy First Nations prior to European colonization, and it remains a cultural centre of the Wabanaki Confederacy to this day.
A flood myth or a deluge myth is a myth in which a great flood, usually sent by a deity or deities, destroys civilization, often in an act of divine retribution. Parallels are often drawn between the flood waters of these myths and the primeval waters which appear in certain creation myths, as the flood waters are described as a measure for the cleansing of humanity, in preparation for rebirth. Most flood myths also contain a culture hero, who "represents the human craving for life".
The Lachlan River is an intermittent river that is part of the Murrumbidgee catchment within the Murray–Darling basin, located in the Southern Tablelands, Central West, and Riverina regions of New South Wales, Australia.
The 1953 North Sea flood was a major flood caused by a heavy storm surge that struck the Netherlands, north-west Belgium, England and Scotland. Most sea defences facing the surge were overwhelmed, resulting in extensive flooding.
In August 2002, a week of intense rainfall produced flooding across a large portion of Europe. It reached the Czech Republic, Italy, Spain, Austria, Germany, Slovakia, Hungary, Romania, Bulgaria, Croatia, Ukraine and Russia. The event killed 232 people and left €27.7 billion (US$27.115 billion) in damage. The flood was of a magnitude expected to occur roughly once a century. Flood heights unknown since St. Mary Magdalene's flood were recorded.
The North Sea flood of 1962 was a natural disaster affecting mainly the coastal regions of West Germany and in particular the city of Hamburg in the night from 16 February to 17 February 1962. In total, the homes of about 60,000 people were destroyed, and the death toll amounted to 315 in Hamburg. The extratropical cyclone responsible for the flooding had previously crossed the United Kingdom as the Great Sheffield Gale, devastating the city of Sheffield and killing nine people.
Rigvedic deities are deities mentioned in the sacred texts of Rigveda, the principal text of the historical Vedic religion of the Vedic period.
European windstorms are powerful extratropical cyclones which form as cyclonic windstorms associated with areas of low atmospheric pressure. They can occur throughout the year, but are most frequent between October and March, with peak intensity in the winter months. Deep areas of low pressure are common over the North Atlantic, and occasionally start as nor'easters off the New England coast. They frequently track across the North Atlantic Ocean towards the north of Scotland and into the Norwegian Sea, which generally minimizes the impact to inland areas; however, if the track is further south, it may cause adverse weather conditions across Central Europe, Northern Europe and especially Western Europe. The countries most commonly affected include the United Kingdom, Ireland, the Netherlands, Norway, Germany, the Faroe Islands and Iceland.
Wilsons River, a perennial river and part of the Richmond River catchment, is situated in the Northern Rivers district of New South Wales, Australia.
The Vistula is the longest river in Poland and the ninth-longest in Europe, at 1,047 kilometres in length. Its drainage basin, extending into three other countries apart from Poland, covers 193,960 km2 (74,890 sq mi), of which 168,868 km2 (65,200 sq mi) is in Poland.
Cyclone Xaver, also known as the North Sea flood or tidal surge of 2013, was a winter storm that affected northern Europe. Force 12 winds and heavy snowfall were predicted along the storm's path, and there were warnings of a significant risk of storm surge leading to coastal flooding along the coasts of the North and Irish Seas.
In July 2021, several European countries were affected by severe floods. Some were catastrophic, causing deaths and widespread damage. The floods started in the United Kingdom as flash floods causing some property damage and inconvenience. Later floods affected several river basins across Europe including Austria, Belgium, Croatia, Germany, Italy, Luxembourg, the Netherlands, and Switzerland. At least 243 people died in the floods, including 196 in Germany, 43 in Belgium, two in Romania, one in Italy and one in Austria.
