Aboiteau
Aboiteau farming on reclaimed marshland is a labor-intensive method in which earthen dikes are constructed to stop high tides from inundating marshland. A wooden sluice or aboiteau (plural aboiteaux) is built into the dike, with a hinged door (clapper valve) that swings open at low tide to allow fresh water to drain from the farmland but swings shut at high tide to prevent salt water from inundating the fields. After several years, the rainwater drained from the marsh eliminates the soil's salinity, making it suitable for farming. Aboiteau farming is intimately linked with the story of French Acadian colonization of the shores of Canada's Bay of Fundy in the 17th and 18th centuries. The Acadians constructed earthen dikes to isolate areas of salt marsh from repeated inundation by the tides. Noted Acadian dikes include the diking of the tidal marshes at Grand-Pré (in contemporary Nova Scotia) in the early 1680s. Around 1755, 13,000 acres of salt marsh were reclaimed using thi ...

Levee
A levee (), dike (American English), dyke (English in the Commonwealth of Nations, Commonwealth English), embankment, floodbank, or stop bank is a structure that is usually soil, earthen and that often runs parallel (geometry), parallel to the course of a river in its floodplain or along low-lying coastlines. The purpose of a levee is to keep the course of rivers from changing and to protect against flooding of the area adjoining the river or coast. Levees can be naturally occurring ridge structures that form next to the bank of a river, or be an artificially constructed fill dirt, fill or wall that regulates water levels. Ancient civilizations in the Indus Valley civilisation, Indus Valley, ancient Egypt, Mesopotamia and China all built levees. Today, levees can be found around the world, and failures of levees due to erosion or other causes can be major disasters.

Grand-Pré, Nova Scotia
Grand-Pré () is a Canadian rural community in Kings County, Nova Scotia. Its French name translates to "Great/Large Meadow" and the community lies at the eastern edge of the Annapolis Valley several kilometres east of the town of Wolfville on a peninsula jutting into the Minas Basin surrounded by extensive dyked farm fields, framed by the Gaspereau and Cornwallis Rivers. The community was made famous by Henry Wadsworth Longfellow's poem Evangeline and is today home to the Grand-Pré National Historic Site. On June 30, 2012, the Landscape of Grand-Pré was named a World Heritage Site by UNESCO. History Grand-Pré was founded in about 1680 by Pierre Melanson and Pierre Terriot. Pierre Melanson, an Acadian settler who traveled east from Pierre Dugua, Sieur de Mons's original settlement at Port Royal (see Annapolis Royal and the Habitation). Pierre, an Acadian of French Huguenot and English extraction, had arrived in Port Royal with Sir Thomas Temple in the 1650s when Acadia was ...

Dam Slit 2D-en
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Marsh
A salt marsh or saltmarsh, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides. It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal protection. Salt marshes have historically been endangered by poorly implemented coastal management practices, with land reclaimed for human uses or polluted by upstream agriculture or other industrial coastal uses. Additionally, sea level rise caused by climate change is endangering other marshes, through erosion and submersion of otherwise tidal marshes. However, recent ackn ...

Kamouraska, Quebec
Kamouraska is a municipality on the south shore of the Saint Lawrence River in the Bas-Saint-Laurent region of Quebec, Canada. It is part of the Regional County Municipality of Kamouraska. It has been named one of the top 20 most beautiful villages in the province of Quebec, and the municipality is a member of the Most Beautiful Villages of Quebec Association. The name "Kamouraska" comes from an Algonquin word meaning "where rushes grow at the water's edge". History The area was settled by French colonists in the late 17th century. In 1674 it was designated as the ''Seigneury de Kamouraska'', a constituent of the ''Gouvernement de Québec'' (fr). There is a long tradition of eel fishing here. An interpretive centre on eel fishing is located in the village. Geography There are salt marshes along the river and there is an ecological reserve near the village.

Pasture
Pasture (from the Latin ''pastus'', past participle of ''pascere'', "to feed") is land used for grazing. Pasture lands in the narrow sense are enclosed tracts of farmland, grazed by domesticated livestock, such as horses, cattle, sheep, or swine. The vegetation of tended pasture, forage, consists mainly of grasses, with an interspersion of legumes and other forbs (non-grass herbaceous plants). Pasture is typically grazed throughout the summer, in contrast to meadow which is ungrazed or used for grazing only after being mown to make hay for animal fodder. Pasture in a wider sense additionally includes rangelands, other unenclosed pastoral systems, and land types used by wild animals for grazing or browsing. Pasture lands in the narrow sense are distinguished from rangelands by being managed through more intensive agricultural practices of seeding, irrigation, and the use of fertilizers, while rangelands grow primarily native vegetation, managed with extensive practices like co ...

Acadians
The Acadians (french: Acadiens , ) are an ethnic group descended from the French who settled in the New France colony of Acadia during the 17th and 18th centuries. Most Acadians live in the region of Acadia, as it is the region where the descendants of a few Acadians who escaped the Expulsion of the Acadians (aka The Great Upheaval / ''Le Grand Dérangement'') re-settled. Most Acadians in Canada continue to live in majority French-speaking communities, notably those in New Brunswick where Acadians and Francophones are granted autonomy in areas such as education and health. Acadia was one of the 5 regions of New France. Acadia was located in what is now Eastern Canada's Maritime provinces, as well as parts of Quebec and present-day Maine to the Kennebec River. It was ethnically, geographically and administratively different from the other French colonies and the French colony of Canada (modern-day Quebec). As a result, the Acadians developed a distinct history and culture. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bay Of Fundy
The Bay of Fundy (french: Baie de Fundy) is a bay between the Canadian provinces of New Brunswick and Nova Scotia, with a small portion touching the U.S. state of Maine. It is an arm of the Gulf of Maine. Its extremely high tidal range is the highest in the world. The name is likely a corruption of the French word , meaning 'split'. Hydrology Tides The tidal range in the Bay of Fundy is about ; the average tidal range worldwide is only . Some tides are higher than others, depending on the position of the moon, the sun, and atmospheric conditions. Tides are semidiurnal, meaning they have two highs and two lows each day, with about six hours and 13 minutes between each high and low tide. Because of tidal resonance in the funnel-shaped bay, the tides that flow through the channel are very powerful. In one 12-hour tidal cycle, about 100 billion tons (110 billion short tons) of water flows in and out of the bay, which is twice as much as the combined total flow of all the rive ...

Marshland
A marsh is a wetland that is dominated by herbaceous rather than woody plant species.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat. Marshes provide habitats for many kinds of invertebrates, fish, amphibians, waterfowl and aquatic mammals. This biological productivity means that marshes contain 0.1% of global sequestered terrestrial carbon. Moreover, they have an outsized influence on climate resil ...

Seawater
Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately of dissolved salts (predominantly sodium () and chloride () ions). The average density at the surface is 1.025 kg/L. Seawater is denser than both fresh water and pure water (density 1.0 kg/L at ) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it freezes at about . The coldest seawater still in the liquid state ever recorded was found in 2010, in a stream under an Antarctic glacier: the measured temperature was . Seawater pH is typically limited to a range between 7.5 and 8.4. However, there is no universally accepted reference pH-scale for seawater and the difference between measurement ...
