An estuary is a enclosed coastal body of brackish water with one or more rivers or streams flowing into it, with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments, they are subject both to marine influences—such as tides and the influx of saline water—and to riverine influences—such as flows of fresh water and sediment. The mixing of sea water and fresh water provide high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are classified according to their geomorphological features or to water-circulation patterns, they can have many different names, such as bays, lagoons, inlets, or sounds, although some of these water bodies do not meet the above definition of an estuary and may be saline.
The banks of many estuaries are amongst the most populated areas of the world, with about 60% of the world's population living along estuaries and the coast. As a result, many estuaries suffer degradation from a variety of factors including: sedimentation from soil erosion from deforestation and other poor farming practices; the word "estuary" is derived from the Latin word aestuarium meaning tidal inlet of the sea, which in itself is derived from the term aestus, meaning tide. There have been many definitions proposed to describe an estuary; the most accepted definition is: "a semi-enclosed coastal body of water, which has a free connection with the open sea, within which sea water is measurably diluted with freshwater derived from land drainage". However, this definition excludes a number of coastal water bodies such as coastal lagoons and brackish seas. A more comprehensive definition of an estuary is "a semi-enclosed body of water connected to the sea as far as the tidal limit or the salt intrusion limit and receiving freshwater runoff.
This broad definition includes fjords, river mouths, tidal creeks. An estuary is a dynamic ecosystem having a connection to the open sea through which the sea water enters with the rhythm of the tides; the sea water entering the estuary streams. The pattern of dilution varies between different estuaries and depends on the volume of fresh water, the tidal range, the extent of evaporation of the water in the estuary. Drowned river valleys are known as coastal plain estuaries. In places where the sea level is rising relative to the land, sea water progressively penetrates into river valleys and the topography of the estuary remains similar to that of a river valley; this is the most common type of estuary in temperate climates. Well-studied estuaries include the Severn Estuary in the United Kingdom and the Ems Dollard along the Dutch-German border; the width-to-depth ratio of these estuaries is large, appearing wedge-shaped in the inner part and broadening and deepening seaward. Water depths exceed 30 m.
Examples of this type of estuary in the U. S. are the Hudson River, Chesapeake Bay, Delaware Bay along the Mid-Atlantic coast, Galveston Bay and Tampa Bay along the Gulf Coast. Bar-built estuaries are found in place where the deposition of sediment has kept pace with rising sea level so that the estuaries are shallow and separated from the sea by sand spits or barrier islands, they are common in tropical and subtropical locations. These estuaries are semi-isolated from ocean waters by barrier beaches. Formation of barrier beaches encloses the estuary, with only narrow inlets allowing contact with the ocean waters. Bar-built estuaries develop on sloping plains located along tectonically stable edges of continents and marginal sea coasts, they are extensive along the Atlantic and Gulf coasts of the U. S. in areas with active coastal deposition of sediments and where tidal ranges are less than 4 m. The barrier beaches that enclose bar-built estuaries have been developed in several ways: building up of offshore bars by wave action, in which sand from the sea floor is deposited in elongated bars parallel to the shoreline, reworking of sediment discharge from rivers by wave and wind action into beaches, overwash flats, dunes, engulfment of mainland beach ridges due to sea level rise and resulting in the breaching of the ridges and flooding of the coastal lowlands, forming shallow lagoons, elongation of barrier spits from the erosion of headlands due to the action of longshore currents, with the spits growing in the direction of the littoral drift.
Barrier beaches form in shallow water and are parallel to the shoreline, resulting in long, narrow estuaries. The average water depth is less than 5 m, exceeds 10 m. Examples of bar-built estuaries are Barnegat Bay, New Jersey. Fjords were formed where pleistocene glaciers deepened and widened existing river valleys so that they become U-shaped in cross s
Subprefectures in France
In France, a subprefecture is the administrative center of a departmental arrondissement that does not contain the prefecture for its department. The term applies to the building that houses the administrative headquarters for an arrondissement; the civil servant in charge of a subprefecture is the subprefect, assisted by a general secretary. Between May 1982 and February 1988, subprefects were known instead by the title commissaire adjoint de la République. Where the administration of an arrondissement is carried out from a prefecture, the general secretary to the prefect carries out duties equivalent to those of the subprefect; the municipal arrondissements of Paris and Marseille are divisions of the city rather than the prefecture, so are not arrondissements in the same sense.

A vineyard is a plantation of grape-bearing vines, grown for winemaking, but raisins, table grapes and non-alcoholic grape juice. The science and study of vineyard production is known as viticulture. A vineyard is characterised by its terroir, a French term loosely translating as "a sense of place" that refers to the specific geographical and geological characteristics of grapevine plantations, which may be imparted in the wine; the earliest evidence of wine production dates from between 6000 and 5000 BC. Wine making technology improved with the ancient Greeks but it wasn't until the end of the Roman Empire that cultivation techniques as we know them were common throughout Europe. In medieval Europe the Church was a staunch supporter of wine, necessary for the celebration of the Mass. During the lengthy instability of the Middle Ages, the monasteries maintained and developed viticultural practices, having the resources, security and interest in improving the quality of their vines, they owned and tended the best vineyards in Europe and vinum theologium was considered superior to all others.
European vineyards were planted with a wide variety of the Vitis vinifera grape. However, in the late 19th century, the entire species was nearly destroyed by the plant louse phylloxera accidentally introduced to Europe from North America. Native American grapevines include varieties such as Vitis labrusca, resistant to the bug. Vitis vinifera varieties were saved by being grafted onto the rootstock of Native American varieties, although there is still no remedy for phylloxera, which remains a danger to any vineyard not planted with grafted rootstock; the quest for vineyard efficiency has produced a bewildering range of systems and techniques in recent years. Due to the much more fertile New World growing conditions, attention has focussed on managing the vine's more vigorous growth. Innovation in palissage and pruning and thinning methods have replaced more general, traditional concepts like "yield per unit area" in favor of "maximizing yield of desired quality". Many of these new techniques have since been adopted in place of traditional practice in the more progressive of the so-called "Old World" vineyards.
Other recent practices include spraying water on vines to protect them from sub-zero temperatures, new grafting techniques, soil slotting, mechanical harvesting. Such techniques have made possible the development of wine industries in New World countries such as Canada. Today there is increasing interest in developing organic, ecologically sensitive and sustainable vineyards. Biodynamics has become popular in viticulture; the use of drip irrigation in recent years has expanded vineyards into areas which were unplantable. For well over half a century, Cornell University, the University of California and California State University, among others, have been conducting scientific experiments to improve viticulture and educate practitioners; the research includes investigating pest control. The International Grape Genome Program is a multi-national effort to discover a genetic means to improving quality, increasing yield and providing a "natural" resistance to pests; the implementation of mechanical harvesting is stimulated by changes in labor laws, labor shortages, bureaucratic complications.
It can be expensive to hire labor for short periods of time, which does not square well with the need to reduce production costs and harvest often at night. However small vineyards, incompatible widths between rows of grape vines and steep terrain hinder the employment of machine harvesting more than the resistance of traditional views which reject such harvesting. Numbers of New World vineyard plantings have been increasing as fast as European vineyards are being uprooted. Between 1990 and 2003, the number of U. S. vineyards increased from 1,180 to 3,860 km2 or 292,000 to 954,000 acres, while Australian vineyard numbers more than doubled from 590 to 1,440 km2 and Chilean vineyards grew from 654 to 1,679 km2. The size of individual vineyards in the New World is significant. Europe's 1.6 million vineyards are an average of 0.2 km2 each, while the average Australian vineyard is 0.5 km2, providing considerable economies of scale. Exports to Europe from New World growers increased by 54% in the six years up to 2006.
There have been significant changes in the kinds of grapes that are grown. For example, in Chile, large areas of low-quality grapes have been replaced with such grapes as Chardonnay and Cabernet Sauvignon. In Argentina, due to an economic down-turn, acreage of Malbec was reduced in the 1980s, but in the 1990s, during the quality revolution incited by Malbec Pioneer Nicolás Catena Zapata, growers started planting more Malbec, most notably in higher altitudes where cooler temperatures and more intense sunlight yields more concentrated yet smoother and more complex malbecs. Grape changes are in response to changing consumer demand but sometimes result from vine pull schemes designed to promote vineyard change. Alternatively, the development of "T" budding now permits the grafting of a different grape variety onto existing rootstock in the vineyard, making it possible to switch varieties within a two-year period. Local legislation dictates which varieties are selected, how they are grown, whether vineyards can be irrigated and when grapes can be harvested, all of which in serves to rein
Union for a Popular Movement
The Union for a Popular Movement was a centre-right political party in France, one of the two major contemporary political parties in France along with the centre-left Socialist Party. The UMP was formed in 2002 as a merger of several centre-right parties under the leadership of President Jacques Chirac. In May 2015, the party was succeeded by The Republicans. Nicolas Sarkozy the president of the UMP, was elected President of France in the 2007 presidential election, but was defeated by PS candidate François Hollande in a run-off five years later. After the November 2012 party congress, the UMP experienced internal fractioning and was plagued by monetary scandals which forced its president, Jean-François Copé, to resign. After his re-election as UMP president in November 2014, Sarkozy put forward an amendment to change the name of the party into The Republicans, approved and came into effect on 30 May 2015; the UMP enjoyed an absolute majority in the National Assembly from 2002 to 2012 and was a member of the European People's Party, the Centrist Democrat International and the International Democrat Union.
Since the 1980s, the political groups of the parliamentary right have joined forces around the values of economic liberalism and the building of Europe. Their rivalries had contributed to their defeat in the 1988 legislative elections. Before the 1993 legislative election, the Gaullist Rally for the Republic and the centrist Union for French Democracy formed an electoral alliance, the Union for France. However, in the 1995 presidential campaign they were both divided between followers of Jacques Chirac, elected, supporters of Prime Minister Edouard Balladur. After their defeat in the 1997 legislative election, the RPR and UDF created the Alliance for France in order to coordinate the actions of their parliamentary groups. Before the 2002 presidential campaign, the supporters of President Jacques Chirac, divided in three centre-right parliamentary parties, founded an association named Union on the Move. After Chirac's re-election, in order to contest the legislative election jointly, the Union for the Presidential Majority was created.
It was as such established as a permanent organisation. The UMP was the merger of the Gaullist-conservative Rally for the Republic, the conservative-liberal party Liberal Democracy, a sizeable portion of the Union for French Democracy, more the UDF's Christian Democrats, the Radical Party and the centrist Popular Party for French Democracy. In the UMP four major French political families were thus represented: Gaullism, Christian democracy and radicalism. Chirac's close ally Alain Juppé became the party's first president at the party's founding congress at the Bourget in November 2002. Juppé won 79.42% of the vote, defeating Nicolas Dupont-Aignan, the leader of the party's Eurosceptic Arise the Republic faction, three other candidates. During the party's earlier years, it was marked by tensions and rivalries between Juppé and other chiraquiens and supporters of Nicolas Sarkozy, the then-Minister of the Interior. In the 2004 regional elections the UMP suffered a heavy blow, winning the presidencies of only 2 out of 22 regions in metropolitan France and only half of the departments in the simultaneous 2004 cantonal elections.
In the 2004 European Parliament election on 13 June 2004, the UMP suffered another heavy blow, winning 16.6% of the vote, far behind the Socialist Party, only 16 seats. Juppé resigned the party's presidency on 15 July 2004 after being found guilty in a corruption scandal in January of the same year. Nicolas Sarkozy announced that he would take over the presidency of the UMP and resign his position as finance minister, ending months of speculation. On 28 November 2004, Sarkozy was elected to the party's presidency with 85.09% of the votes against 9.1% for Dupont-Aignan and 5.82% for Christine Boutin, the leader of the UMP's social conservatives. Having gained control of what had been Chirac's party, Sarkozy focused the party machinery and his energies on the 2007 presidential election; the failure of the referendum on the European Constitution on 25 May 2005 led to the fall of the government of Jean-Pierre Raffarin and to the formation of a new cabinet, presided by another UMP politician, Dominique de Villepin.
However, during this time, the UMP under Sarkozy gained a record number of new members and rejuvenated itself in preparation of the 2007 election. On 14 January 2007, Sarkozy was nominated unopposed as the UMP's presidential candidate for the 2007 election. On the issues, the party under Sarkozy publicly disapproved of Turkey's proposed membership in the European Union, which Chirac had endorsed several times publicly, took a more right-wing position. On 22 April 2007 Nicolas Sarkozy won the plurality of votes in the first round of the 2007 presidential election. On 6 May he faced the Socialist Party candidate Ségolène Royal in the second round and won, taking 53.06% of the vote. As a consequence, he resigned from the presidency of the UMP on 14 May 2007, two days before becoming President of the French Republic. François Fillon was appointed Prime Minister. On 17 June 2007, at a
The river Armançon drains part of north-western Burgundy in France. It flows into the Yonne at Migennes, its source is at about 380 m above sea level and it enters the Yonne, 202 km downstream, at 79 m. The Armançon rises 2 km north-west of Meilly-sur-Rouvres in the district known as the Auxois, on the lip of the saucer represented by the Paris Basin, it flows on the margin of the Morvan. Its source is on the Lower Jurassic rocks where they and the Upper Triassic are much influenced by the granites and volcanism of the Morvan, a northward extension of the Massif Central; the river's upper valley is used by the Canal de Bourgogne and the Autoroute A6 but the two diverge and the river passes between them, alone towards the small town of Semur-en-Auxois. In this part of its course the river has cut its valley down through the Jurassic rocks to the underlying granite; the Cernant joins just below Semur. Near Buffon, north-west of Montbard, the canal joins it again from the Brenne valley accompanied by the Dijon to Paris railway.
The Bornant enters from the left lower. They all pass through forested country on Middle Jurassic geology. Shortly after, they pass into the department of Yonne. Near the border between the departments and just below Ravières, the river passes onto the Upper Jurassic where the valley bottom has accumulated Holocene alluvium. However, the Upper Jurassic rocks are available to supply the clay element of the materials for the cement works which lie between the river and the canal between Pacy-sur-Armançon and Lézinnes. Still in forested country, it passes the small town of Tonnerre and passes briefly through the department of Aube as it flows onto the lower Cretaceous rocks, clothed in less woodland. Just below Saint-Florentin it is crossed by the TGV railway from Paris to Avignon; the river arrives on the Middle Cretaceous as the Créanton joins from the right, just before the river and the Canal de Bourgogne enter the Yonne at Migennes. The town is backed by the treeless Upper Cretaceous chalk; the Lower Cretaceous is comparable with the rocks of the Weald of southern England and the Upper Jurassic with the Oxford Clay and associated strata of the English Midlands.
The middle Jurassic rocks contain more limestones. The Upper Cretaceous is chalk Its principal tributaries are: the Rû de Bierre the Ruisseau de Bornant the Cernant the Brenne the Bornant the Brionne the Ruisseau de Cléon the Armance the Créanton the Ruisseau de Larry the Prée the Ruisseau de Thorey Ru is an old or literary word for "brook".

Nièvre is a department in the region of Bourgogne-Franche-Comté in the centre of France named after the River Nièvre. Nièvre is one of the original 83 departments created during the French Revolution on 4 March 1790, it was created from the former province of Nivernais. Nièvre is part of the current region of Bourgogne-Franche-Comté, although it was not part of the province of Burgundy, it is surrounded by the departments of Yonne, Côte-d'Or, Saône-et-Loire, Allier and Loiret. The department is crossed by the longest river in France. Nièvre is a rural department with about 33 inhabitants per km²; the main cities are Nevers, Cosne-sur-Loire, Varennes-Vauzelles, Decize, Clamecy and La Charité. Only two cities reach 10 000 inhabitants, it indicates the characteristic of the department, predominantly rural. Nièvre is well known for its white wine, Pouilly Fumé; the vineyards are scattered around villages including Pouilly-Sur-Loire, which lends its name to the appellation, Tracy sur Loire, Saint Andelain.
The word fumé is French for "smoky", it is said the name comes from the smoky or flinty quality of these wines. The only grape allowed in the Pouilly-Fumé AC is Sauvignon blanc, which produces wines that are crisp and somewhat grassy. In common with most French wine-producing departments, Nièvre is traditionally a left-wing department; the results of the second round of voting in presidential elections reflect this consistently: In the 2007 presidential election, Ségolène Royal received 52.91% of the department's votes, as against a national per centage of just 46.94%. In the 1995 presidential election, Lionel Jospin received 57.07% of the department's votes, as against a national per centage of just 47.36%. In the 1981 presidential election, François Mitterrand received 62.91% of the department's votes, as against a national per centage of 51.76%. Nièvre's best-known political representative was François Mitterrand who served as a senator and a deputy for the department, as mayor of Château-Chinon for 22 years before his election to the presidency in 1981.
The Circuit de Nevers Magny-Cours hosted the Formula One French Grand Prix from 1991 to 2008, the Bol d'Or from 2000 to 2014, the French round of the Superbike World Championship since 2003.

Socialist Party (France)
The Socialist Party is a social-democratic political party in France and was, for decades, the largest party of the French centre-left. The PS used to be one of the two major political parties in the French Fifth Republic, along with the Republicans; the Socialist Party replaced the earlier French Section of the Workers' International in 1969, is led by First Secretary Olivier Faure. The PS is a member of the Party of European Socialists, the Socialist International and the Progressive Alliance; the PS first won power in 1981, when its candidate François Mitterrand was elected President of France in the 1981 presidential election. Under Mitterrand, the party achieved a governing majority in the National Assembly from 1981 to 1986 and again from 1988 to 1993. PS leader Lionel Jospin lost his bid to succeed Mitterrand as president in the 1995 presidential election against Rally for the Republic leader Jacques Chirac, but became prime minister in a cohabitation government after the 1997 parliamentary elections, a position Jospin held until 2002, when he was again defeated in the presidential election.
In 2007, the party's candidate for the presidential election, Ségolène Royal, was defeated by conservative UMP candidate Nicolas Sarkozy. The Socialist party won most of regional and local elections and it won control of the Senate in 2011 for the first time in more than fifty years. On 6 May 2012, François Hollande, the First Secretary of the Socialist Party from 1997 to 2008, was elected President of France, the next month, the party won the majority in the National Assembly; the PS formed several figures who acted at the international level: Jacques Delors, the eighth President of the European Commission from 1985 to 1994 and the first person to serve three terms in that office, was from the Socialist Party, as well as Dominique Strauss-Kahn, the Managing Director of the International Monetary Fund from 2007 to 2011, Pascal Lamy, Director-General of the World Trade Organization from 2005 to 2013. The party had 42,300 members in 2016, down from 60,000 in 2014 and 173,486 members in 2012.
The defeat of the Paris commune reduced the power and influence of the socialist movements in France. Its leaders were exiled. France's first socialist party, the Federation of the Socialist Workers of France, was founded in 1879, it was characterised as "possibilist". Two parties split off from it: in 1882, the French Workers' Party of Jules Guesde and Paul Lafargue in 1890 the Revolutionary Socialist Workers' Party of Jean Allemane. At the same time, the heirs of Louis Auguste Blanqui, a symbol of the French revolutionary tradition, created the Central Revolutionary Committee led by Édouard Vaillant. There were some declared socialist deputies such as Alexandre Millerand and Jean Jaurès who did not belong to any party. In 1899, the participation of Millerand in Pierre Waldeck-Rousseau's cabinet caused a debate about socialist participation in a "bourgeois government". Three years Jaurès, Allemane and the possibilists founded the possibilist French Socialist Party, which supported participation in government, while Guesde and Vaillant formed the Socialist Party of France, which opposed such co-operation.
In 1905, during the Globe Congress, the two groups merged in the French Section of the Workers International. Leader of the parliamentary group and director of the party paper L'Humanité, Jaurès was its most influential figure; the party was hemmed in between the middle-class liberals of the Radical Party and the revolutionary syndicalists who dominated the trade unions. Furthermore, the goal to rally all the Socialists in one single party was reached: some elects refused to join the SFIO and created the Republican-Socialist Party, which supported socialist participation in liberal governments. Together with the Radicals, who wished to install laicism, the SFIO was a component of the Left Block without to sit in the government. In 1906, the General Confederation of Labour trade union claimed its independence from all political parties; the French socialists were anti-war, but following the assassination of Jaurès in 1914 they were unable to resist the wave of militarism which followed the outbreak of World War I.
They suffered a severe split over participation in the wartime government of national unity. In 1919 the anti-war socialists were defeated in elections. In 1920, during the Tours Congress, the majority and left wing of the party broke away and formed the French Section of the Communist International to join the Third International founded by Vladimir Lenin; the right wing, led by Léon Blum, kept the "old house" and remained in the SFIO. In 1924 and in 1932, the Socialists joined with the Radicals in the Coalition of the Left, but refused to join the non-Socialist governments led by the Radicals Édouard Herriot and Édouard Daladier; these governments failed because the Socialists and the Radicals could not agree on economic policy, because the Communists, following the policy laid down by the Soviet Union, refused to support governments presiding over capitalist economies. The question of the possibility of a government participation with Radicals caused the split of "neosocialists" at the beginning of the 1930s.
They merged with the Republican-Socialist Party in the Socialist Republican Union. In 1934, the Communists changed their line, the four left-wing parties came together in the Popular Front, which won the 1936 elections and brought Blum to power as France's first SFIO Prime Minister. Indeed, for the first time in its history, the SFIO obtained more votes and seats than the Ra
