In geography , a bank is the land alongside a body of water . Different structures are referred to as banks in different fields of geography, as follows.
118-517: A reservoir ( / ˈ r ɛ z ər v w ɑːr / ; from French réservoir [ʁezɛʁvwaʁ] ) is an enlarged lake behind a dam , usually built to store fresh water , often doubling for hydroelectric power generation . Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. The term
236-416: A marsh , swamp , slough , or estuary , sometimes called a bank, is likewise studied in freshwater ecology. Banks are also of interest in navigation , where the term can refer either to a barrier island or a submerged plateau , such as an ocean bank . A barrier island is a long narrow island composed of sand and forming a barrier between an island lagoon or sound and the ocean. A submerged plateau

The prefect of Basses-Pyrénées in the French Basque Country wrote in 1846: "Our schools in the Basque Country are particularly meant to replace the Basque language with French..." Students were taught that their ancestral languages were inferior and they should be ashamed of them; this process
472-535: A block for migrating fish, trapping them in one area, producing food and a habitat for various water-birds. They can also flood various ecosystems on land and may cause extinctions. Creating reservoirs can alter the natural biogeochemical cycle of mercury . After a reservoir's initial formation, there is a large increase in the production of toxic methylmercury (MeHg) via microbial methylation in flooded soils and peat. MeHg levels have also been found to increase in zooplankton and in fish. Dams can severely reduce
590-812: A chain up the valley. Coastal reservoirs are fresh water storage reservoirs located on the sea coast near a river mouth to store the flood water of a river. As the land-based reservoir construction is fraught with substantial land submergence, coastal reservoirs are preferred economically and technically since they do not use scarce land area. Many coastal reservoirs were constructed in Asia and Europe. Saemanguem in South Korea, Marina Barrage in Singapore, Qingcaosha in China, and Plover Cove in Hong Kong are
708-431: A comprehensive academic study entitled "The World's 10 most influential languages". In the article, Weber ranked French as, after English, the second-most influential language of the world, ahead of Spanish. His criteria were the numbers of native speakers, the number of secondary speakers (especially high for French among fellow world languages), the number of countries using the language and their respective populations,
826-656: A conventional oil-fired thermal generation plant. For instance, In 1990, the impoundment behind the Balbina Dam in Brazil (inaugurated in 1987) had over 20 times the impact on global warming than would generating the same power from fossil fuels, due to the large area flooded per unit of electricity generated. Another study published in the Global Biogeochemical Cycles also found that newly flooded reservoirs released more carbon dioxide and methane than

Vast artificial reservoirs were also built by various ancient kingdoms in Bengal, Assam, and Cambodia. Many dammed river reservoirs and most bank-side reservoirs are used to provide the raw water feed to a water treatment plant which delivers drinking water through water mains. The reservoir does not merely hold water until it
1062-523: A few such coastal reservoirs. Where water is pumped or siphoned from a river of variable quality or size, bank-side reservoirs may be built to store the water. Such reservoirs are usually formed partly by excavation and partly by building a complete encircling bund or embankment , which may exceed 6 km (4 miles) in circumference. Both the floor of the reservoir and the bund must have an impermeable lining or core: initially these were often made of puddled clay , but this has generally been superseded by
1180-555: A foreign language. Due to the rise of French in Africa, the total French-speaking population worldwide is expected to reach 700 million people in 2050. French is the fastest growing language on the continent (in terms of either official or foreign languages). French is increasingly being spoken as a native language in Francophone Africa, especially in regions like Ivory Coast , Cameroon , Gabon, Madagascar , and
1298-454: A high-level reservoir is filled with water using high-performance electric pumps at times when electricity demand is low, and then uses this stored water to generate electricity by releasing the stored water into a low-level reservoir when electricity demand is high. Such systems are called pump-storage schemes. Reservoirs can be used in a number of ways to control how water flows through downstream waterways: Reservoirs can be used to balance

In summary, they consider it a misadaptation to climate change. Proponents of reservoirs or substitution reserves, on the other hand, see them as a solution for sustainable agriculture while waiting for a truly durable agricultural model. Without such reserves, they fear that unsustainable imported irrigation will be inevitable. They believe that these reservoirs should be accompanied by
1534-418: A narrow valley or canyon may cover relatively little vegetation, while one situated on a plain may flood a great deal of vegetation. The site may be cleared of vegetation first or simply flooded. Tropical flooding can produce far more greenhouse gases than in temperate regions. The following table indicates reservoir emissions in milligrams per square meter per day for different bodies of water. Depending upon
1652-705: A period of prosperity and prominence among European nations. Richelieu established the Académie française to protect the French language. By the early 1800s, Parisian French had become the primary language of the aristocracy in France. Near the beginning of the 19th century, the French government began to pursue policies with the end goal of eradicating the many minorities and regional languages ( patois ) spoken in France. This began in 1794 with Henri Grégoire 's "Report on
1770-494: A relic of the old nominal case system of Latin longer than most other Romance languages (with the notable exception of Romanian which still currently maintains a case distinction), differentiating between an oblique case and a nominative case. The phonology was characterized by heavy syllabic stress, which led to the emergence of various complicated diphthongs such as -eau which would later be leveled to monophthongs. The earliest evidence of what became Old French can be seen in
1888-610: A reservoir is called the "conservation pool". In the United Kingdom, "top water level" describes the reservoir full state, while "fully drawn down" describes the minimum retained volume. There is a wide variety of software for modelling reservoirs, from the specialist Dam Safety Program Management Tools (DSPMT) to the relatively simple WAFLEX , to integrated models like the Water Evaluation And Planning system (WEAP) that place reservoir operations in
2006-683: A result of French and Belgian colonialism from the 16th century onward, French was introduced to new territories in the Americas, Africa, and Asia. French has a long history as an international language of literature and scientific standards and is a primary or second language of many international organisations including the United Nations , the European Union, the North Atlantic Treaty Organization ,
2124-738: A river valley, with the potential to wash away towns and villages and cause considerable loss of life, such as the devastation following the failure of containment at Llyn Eigiau which killed 17 people.(see also List of dam failures ) A notable case of reservoirs being used as an instrument of war involved the British Royal Air Force Dambusters raid on Germany in World War II (codenamed " Operation Chastise "), in which three German reservoir dams were selected to be breached in order to damage German infrastructure and manufacturing and power capabilities deriving from
2242-580: A territorial project that unites all water stakeholders with the goal of preserving and enhancing natural environments. Two main types of reservoirs can be distinguished based on their mode of supply. Circa 3000 BC, the craters of extinct volcanoes in Arabia were used as reservoirs by farmers for their irrigation water. Dry climate and water scarcity in India led to early development of stepwells and other water resource management techniques, including

French is also an official language of all of the territories ( Northwest Territories , Nunavut , and Yukon ). Out of the three, Yukon has the most French speakers, making up just under 4% of the population. Furthermore, while French is not an official language in Ontario , the French Language Services Act ensures that provincial services are available in
3422-500: Is greater acceptance because all beneficiary users are involved in the implementation of the system. The specific debate about substitution reservoirs is part of a broader discussion related to reservoirs used for agricultural irrigation, regardless of their type, and a certain model of intensive agriculture. Opponents view these reservoirs as a monopolization of resources benefiting only a few, representing an outdated model of productive agriculture. They argue that these reservoirs lead to

According to the World Commission on Dams report (Dams And Development), when the reservoir is relatively large and no prior clearing of forest in the flooded area was undertaken, greenhouse gas emissions from the reservoir could be higher than those of
9440-516: The first government authority to adopt Modern French as official was the Aosta Valley in 1536, while the Ordinance of Villers-Cotterêts (1539) named French the language of law in the Kingdom of France . During the 17th century, French replaced Latin as the most important language of diplomacy and international relations ( lingua franca ). It retained this role until approximately the middle of
9558-413: The flow in highly managed systems, taking in water during high flows and releasing it again during low flows. In order for this to work without pumping requires careful control of water levels using spillways . When a major storm approaches, the dam operators calculate the volume of water that the storm will add to the reservoir. If forecast storm water will overfill the reservoir, water is slowly let out of
9676-915: The former Yugoslavia , International Criminal Tribunal for Rwanda , the International Tribunal for the Law of the Sea the International Criminal Court and the World Trade Organization Appellate Body . It is the sole internal working language of the Court of Justice of the European Union , and makes with English the European Court of Human Rights 's two working languages. In 1997, George Weber published, in Language Today ,
9794-829: The gender of the corresponding word in Gaulish. The estimated number of French words that can be attributed to Gaulish is placed at 154 by the Petit Robert , which is often viewed as representing standardized French, while if non-standard dialects are included, the number increases to 240. Known Gaulish loans are skewed toward certain semantic fields, such as plant life ( chêne , bille , etc.), animals ( mouton , cheval , etc.), nature ( boue , etc.), domestic activities (ex. berceau ), farming and rural units of measure ( arpent , lieue , borne , boisseau ), weapons, and products traded regionally rather than further afield. This semantic distribution has been attributed to peasants being
9912-578: The hydroelectric reservoirs there do emit greenhouse gases, it is on a much smaller scale than thermal power plants of similar capacity. Hydropower typically emits 35 to 70 times less greenhouse gases per TWh of electricity than thermal power plants. A decrease in air pollution occurs when a dam is used in place of thermal power generation, since electricity produced from hydroelectric generation does not give rise to any flue gas emissions from fossil fuel combustion (including sulfur dioxide , nitric oxide and carbon monoxide from coal ). Dams can produce
10030-432: The landscape is relatively flat. Other service reservoirs can be storage pools, water tanks or sometimes entirely underground cisterns , especially in more hilly or mountainous country. Modern reserviors will often use geomembrane liners on their base to limit seepage and/or as floating covers to limit evaporation, particularly in arid climates. In the United Kingdom, Thames Water has many underground reservoirs built in
10148-454: The language are very closely related to those of the rest of the French-speaking world. French is the second most commonly spoken language in Canada and one of two federal official languages alongside English. As of the 2021 Canadian census , it was the native language of 7.7 million people (21% of the population) and the second language of 2.9 million (8% of the population). French
10266-479: The language, although it has now given way to Tamil and English. A former French mandate , Lebanon designates Arabic as the sole official language, while a special law regulates cases when French can be publicly used. Article 11 of Lebanon's Constitution states that "Arabic is the official national language. A law determines the cases in which the French language is to be used". The French language in Lebanon
10384-612: The language. The Act applies to areas of the province where there are significant Francophone communities, namely Eastern Ontario and Northern Ontario . Elsewhere, sizable French-speaking minorities are found in southern Manitoba, Nova Scotia , Prince Edward Island and the Port au Port Peninsula in Newfoundland and Labrador, where the unique Newfoundland French dialect was historically spoken. Smaller pockets of French speakers exist in all other provinces. The Ontarian city of Ottawa ,
10502-479: The last to hold onto Gaulish. The beginning of French in Gaul was greatly influenced by Germanic invasions into the country. These invasions had the greatest impact on the northern part of the country and on the language there. A language divide began to grow across the country. The population in the north spoke langue d'oïl while the population in the south spoke langue d'oc . Langue d'oïl grew into what
10620-470: The modern use of rolled clay. The water stored in such reservoirs may stay there for several months, during which time normal biological processes may substantially reduce many contaminants and reduce turbidity . The use of bank-side reservoirs also allows water abstraction to be stopped for some time, for instance when the river is unacceptably polluted or when flow conditions are very low due to drought . The London water supply system exhibits one example of
10738-420: The necessity and means to annihilate the patois and to universalize the use of the French language". When public education was made compulsory , only French was taught and the use of any other ( patois ) language was punished. The goals of the public school system were made especially clear to the French-speaking teachers sent to teach students in regions such as Occitania and Brittany . Instructions given by
10856-608: The new top water level exceeds the watershed height on one or more of the feeder streams such as at Llyn Clywedog in Mid Wales . In such cases additional side dams are required to contain the reservoir. Where the topography is poorly suited to forming a single large reservoir, a number of smaller reservoirs may be constructed in a chain, as in the River Taff valley where the Llwyn-on , Cantref and Beacons Reservoirs form
10974-415: The operating rules may be complex. Most modern reservoirs have a specially designed draw-off tower that can discharge water from the reservoir at different levels, both to access water as the water level falls, and to allow water of a specific quality to be discharged into the downstream river as "compensation water": the operators of many upland or in-river reservoirs have obligations to release water into
11092-428: The original streambed of the downstream river and are filled by creeks , rivers or rainwater that runs off the surrounding forested catchments, or off-stream reservoirs , which receive diverted water from a nearby stream or aqueduct or pipeline water from other on-stream reservoirs. Dams are typically located at a narrow part of a downstream of a natural basin. The valley sides act as natural walls, with
11210-534: The other main foreign language in the Vietnamese educational system and is regarded as a cultural language. All three countries are full members of La Francophonie (OIF). French was the official language of French India , consisting of the geographically separate enclaves referred to as Puducherry . It continued to be an official language of the territory even after its cession to India in 1956 until 1965. A small number of older locals still retain knowledge of
11328-426: The pre-flooded landscape, noting that forest lands, wetlands, and preexisting water features all released differing amounts of carbon dioxide and methane both pre- and post-flooding. The Tucuruí Dam in Brazil (completed in 1984) had only 0.4 times the impact on global warming than would generating the same power from fossil fuels. A two-year study of carbon dioxide and methane releases in Canada concluded that while
11446-471: The preferred language of certain institutions or administrations such as the Court of Justice of the European Union , where it is the sole internal working language, or the Directorate-General for Agriculture . Since 2016, Brexit has rekindled discussions on whether or not French should again hold greater role within the institutions of the European Union. A leading world language , French
11564-402: The processes associated with rivers and streams and the deposits and landforms created by them. Bankfull discharge is a discharge great enough to fill the channel and overtop the banks. The descriptive terms left bank and right bank refer to the perspective of an observer looking downstream ; a well-known example of this being the southern left bank and the northern right bank of
11682-437: The quality of the water and the ecology of the surrounding area. Many reservoirs now support and encourage less formal and less structured recreation such as natural history , bird watching , landscape painting , walking and hiking , and often provide information boards and interpretation material to encourage responsible use. Water falling as rain upstream of the reservoir, together with any groundwater emerging as springs,
11800-461: The relocation of the village of Capel Celyn during the construction of Llyn Celyn , and the relocation of Borgo San Pietro of Petrella Salto during the construction of Lake Salto . Construction of a dammed reservoir will usually require the river to be diverted during part of the build, often through a temporary tunnel or by-pass channel. In hilly regions, reservoirs are often constructed by enlarging existing lakes. Sometimes in such reservoirs,
11918-638: The reservoir prior to, and during, the storm. If done with sufficient lead time, the major storm will not fill the reservoir and areas downstream will not experience damaging flows. Accurate weather forecasts are essential so that dam operators can correctly plan drawdowns prior to a high rainfall event. Dam operators blamed a faulty weather forecast on the 2010–2011 Queensland floods . Examples of highly managed reservoirs are Burrendong Dam in Australia and Bala Lake ( Llyn Tegid ) in North Wales . Bala Lake
12036-471: The rest largely speak French as a first language. As a French Creole language , Haitian Creole draws the large majority of its vocabulary from French, with influences from West African languages, as well as several European languages. It is closely related to Louisiana Creole and the creole from the Lesser Antilles . French is the sole official language of all the overseas territories of France in
12154-480: The river Seine defining parts of Paris . The shoreline of ponds , swamps , estuaries , reservoirs , or lakes are also of interest in limnology and are sometimes referred to as banks. The grade of all these banks or shorelines can vary from vertical to a shallow slope. In freshwater ecology , banks are of interest as the location of riparian habitats . Riparian zones occur along upland and lowland river and stream beds. The ecology around and depending on
12272-466: The total number of French speakers will reach approximately 500 million in 2025 and 650 million by 2050, largely due to rapid population growth in sub-Saharan Africa . OIF estimates 700 million French speakers by 2050, 80% of whom will be in Africa. In a study published in March 2014 by Forbes , the investment bank Natixis said that French could become the world's most spoken language by 2050. In
12390-679: The two official languages—along with Dutch —of the Brussels-Capital Region , where it is spoken by the majority of the population (approx. 80%), often as their primary language. French is one of the four official languages of Switzerland, along with German, Italian, and Romansh , and is spoken in the western part of Switzerland, called Romandy , of which Geneva is the largest city. The language divisions in Switzerland do not coincide with political subdivisions, and some cantons have bilingual status: for example, cities such as Biel/Bienne and cantons such as Valais , Fribourg and Bern . French
12508-508: The urban intellectual elite. The Gaulish language likely survived into the sixth century in France despite considerable Romanization . Coexisting with Latin, Gaulish helped shape the Vulgar Latin dialects that developed into French contributing loanwords and calques (including oui , the word for "yes"), sound changes shaped by Gaulish influence, and influences in conjugation and word order. Recent computational studies suggest that early gender shifts may have been motivated by
12626-485: The use of French in official government publications, public education except in specific cases, and legal contracts; advertisements must bear a translation of foreign words. In Belgium, French is an official language at the federal level along with Dutch and German. At the regional level, French is the sole official language of Wallonia (excluding a part of the East Cantons , which are German-speaking ) and one of
12744-497: The use of bank-side storage: here water is taken from the River Thames and River Lee into several large Thames-side reservoirs, such as Queen Mary Reservoir that can be seen along the approach to London Heathrow Airport . Service reservoirs store fully treated potable water close to the point of distribution. Many service reservoirs are constructed as water towers , often as elevated structures on concrete pillars where
12862-412: The water, which tends to partition some elements such as manganese and phosphorus into deep, cold anoxic water during the summer months. In the autumn and winter the lake becomes fully mixed again. During drought conditions, it is sometimes necessary to draw down the cold bottom water, and the elevated levels of manganese in particular can cause problems in water treatment plants. In 2005, about 25% of
12980-536: The workplace. In 2011, Bloomberg Businessweek ranked French the third most useful language for business, after English and Standard Mandarin Chinese . In English-speaking Canada, the United Kingdom, and Ireland, French is the first foreign language taught and in number of pupils is far ahead of other languages. In the United States, French is the second-most commonly taught foreign language in schools and universities, although well behind Spanish. In some areas of
13098-474: The world's 33,105 large dams (over 15 metres in height) were used for hydroelectricity. The U.S. produces 3% of its electricity from 80,000 dams of all sizes. An initiative is underway to retrofit more dams as a good use of existing infrastructure to provide many smaller communities with a reliable source of energy. A reservoir generating hydroelectricity includes turbines connected to the retained water body by large-diameter pipes. These generating sets may be at
13216-402: The world's French-speaking population lives in Africa. According to a 2023 estimate from the Organisation internationale de la Francophonie , an estimated 167 million African people spread across 35 countries and territories can speak French as either a first or a second language . This number does not include the people living in non-Francophone African countries who have learned French as
13334-503: The world, with about 50 countries and territories having it as a de jure or de facto official, administrative, or cultural language. Most of these countries are members of the Organisation internationale de la Francophonie (OIF), the community of 54 member states which share the official use or teaching of French. It is spoken as a first language (in descending order of the number of speakers) in France; Canada (especially in
13452-819: Was during the period of the Crusades in which French became so dominant in the Mediterranean Sea that became a lingua franca ("Frankish language"), and because of increased contact with the Arabs during the Crusades who referred to them as Franj , numerous Arabic loanwords entered French, such as amiral (admiral), alcool (alcohol), coton (cotton) and sirop (syrop), as well as scientific terms such as algébre (algebra), alchimie (alchemy) and zéro (zero). Within Old French many dialects emerged but
13570-400: Was gradually adopted by the inhabitants of Gaul. As the language was learned by the common people, it developed a distinct local character, with grammatical differences from Latin as spoken elsewhere, some of which is attested in graffiti. This local variety evolved into the Gallo-Romance tongues, which include French and its closest relatives, such as Arpitan . The evolution of Latin in Gaul
13688-652: Was known in the Occitan-speaking region as Vergonha . Spoken by 19.71% of the European Union's population, French is the third most widely spoken language in the EU, after English and German and the second-most-widely taught language after English. Under the Constitution of France , French has been the official language of the Republic since 1992, although the Ordinance of Villers-Cotterêts made it mandatory for legal documents in 1539. France mandates
13806-594: Was shaped by its coexistence for over half a millennium beside the native Celtic Gaulish language , which did not go extinct until the late sixth century, long after the fall of the Western Roman Empire . The population remained 90% indigenous in origin; the Romanizing class were the local native elite (not Roman settlers), whose children learned Latin in Roman schools. At the time of the collapse of
13924-570: Was the language they use the most at home rose from 67% at the 2007 census to 74% at the 2017 census. In Wallis and Futuna, the percentage of the population who reported that French was the language they use the most at home rose from 10% at the 2008 census to 13% at the 2018 census. According to a demographic projection led by the Université Laval and the Réseau Démographie de l'Agence universitaire de la Francophonie ,
