85-521: Many riverside communes have incorporated the Isère's name into their own, for example, Sainte-Hélène-sur-Isère and Romans-sur-Isère . The department of Isère is likewise named after the river. The name Isère was first recorded under the form Isara , which means "the impetuous one, the swift one." Not originally a Celtic word, it was very likely assimilated by the Celts in ancient times. This word

170-585: A fluvioglacial system , led to the formation of several stepped terraces in the lower Isère valley, like the one on which Saint-Marcel-lès-Valence is built. This occurred through the massive accumulation of alluvium from the Isère on top of a bed of Miocene molasse . Today, these terraces still define the geography of the Plain of Valence. The Isère initially merges with one of the Rhône's diversion canals, built for navigational purposes, at Pont-de-l'Isère . At

255-602: A tripoint . Various examples are found in the list below. A number of major cities, such as Chongqing , St. Louis , and Khartoum , arose at confluences; further examples appear in the list. Within a city, a confluence often forms a visually prominent point, so that confluences are sometimes chosen as the site of prominent public buildings or monuments, as in Koblenz , Lyon , and Winnipeg . Cities also often build parks at confluences, sometimes as projects of municipal improvement, as at Portland and Pittsburgh . In other cases,

340-421: A "realm of 100,000 steeples". Parishes lacked the municipal structures of post-Revolution communes. Usually, one contained only a building committee ( conseil de fabrique ), made up of villagers, which managed the buildings of the parish church, the churchyard, and the other numerous church estates and properties, and sometimes also provided help for the poor, or even administered parish hospitals or schools. Since

425-445: A category currently being phased out), made up of 33,327 communes (91.1 percent of all the communes of metropolitan France), and 52.86 million inhabitants, i.e., 86.7 percent of the population of metropolitan France. These impressive results however may hide a murkier reality. In rural areas, many communes have entered a community of communes only to benefit from government funds. Often the local syndicate has been turned officially into

510-537: A commune for their administration. This is unlike some other countries, such as the United States, where unincorporated areas directly governed by a county or a higher authority can be found. There are only a few exceptions: Furthermore, two regions without permanent habitation have no communes: In metropolitan France , the average area of a commune in 2004 was 14.88 square kilometres (5.75 sq mi). The median area of metropolitan France's communes at

595-537: A community of communes, the new community of communes in fact managing only the services previously managed by the syndicate, contrary to the spirit of the law which has established the new intercommunal structures to carry out a much broader range of activities than that undertaken by the old syndicates. Some say that, should government money transfers be stopped, many of these communities of communes would revert to their former status of syndicate, or simply completely disappear in places where there were no syndicates prior to

680-414: A confluence can be divided into six distinct features which are commonly called confluence flow zones (CFZ). These include The broader field of engineering encompasses a vast assortment of subjects which concern confluences. In hydraulic civil engineering , where two or more underground culverted / artificially buried watercourses intersect, great attention should be paid to the hydrodynamic aspects of

765-630: A confluence is an industrial site, as in Philadelphia or Mannheim . Often a confluence lies in the shared floodplain of the two rivers and nothing is built on it, for example at Manaus , described below. One other way that confluences may be exploited by humans is as sacred places in religions . Rogers suggests that for the ancient peoples of the Iron Age in northwest Europe, watery locations were often sacred, especially sources and confluences. Pre-Christian Slavic peoples chose confluences as

850-482: A corresponding shift in habitat characteristics." Another science relevant to the study of confluences is chemistry , because sometimes the mixing of the waters of two streams triggers a chemical reaction, particularly in a polluted stream. The United States Geological Survey gives an example: "chemical changes occur when a stream contaminated with acid mine drainage combines with a stream with near-neutral pH water; these reactions happen very rapidly and influence

935-589: A density of communes as France, and even there an extensive merger movement has started in the last 10 years. To better grasp the staggering number of communes in France, two comparisons can be made: First, of the original 15 member states of the European Union there are approximately 75,000 communes; France alone, which comprises 16 percent of the population of the EU-15, had nearly half of its communes. Second,

1020-656: A level of administrative division in the French Republic . French communes are analogous to civil townships and incorporated municipalities in the United States and Canada, Gemeinden in Germany, comuni in Italy, or municipios in Spain. The UK equivalent are civil parishes . Communes are based on historical geographic communities or villages and are vested with significant powers to manage

1105-769: A massive merger of communes, including by such distinguished voices as the president of the Cour des Comptes (the central auditing administrative body in France). In 1971 the Marcellin law offered support and money from the government to entice the communes to merge freely with each other, but the law had only a limited effect (only about 1,300 communes agreed to merge with others). Many rural communes with few residents struggle to maintain and manage basic services such as running water, garbage collection, or properly paved communal roads. Mergers, however, are not easy to achieve. One problem

1190-592: A much larger territory covering 449,964 km (173,732 sq mi) and yet is divided into only 290 municipalities ( kommuner ). Alsace has more than double the total number of municipalities of the Netherlands which, in spite of having a population nine times larger and a land area four times larger than Alsace, is divided into just 390 municipalities ( gemeenten ). Most of the communes in Alsace, along with those in other regions of France, have rejected

1275-893: A wide variety of landscapes: from its source near the Italian border in the western Alps, it crosses the Pays de Savoie and the Tarentaise Valley , cuts between the Chartreuse and Belledonne mountain ranges, follows the Vercors Massif , passes through the Dauphiné province , and finally meets with the Rhône at the foot of the Vivarais . The upper valley of the Isère is called the Tarentaise , and its middle valley

1360-662: Is 35 km (14 sq mi); and in Germany , the majority of Länder have communes ( Gemeinden ) with a median area above 15 km (5.8 sq mi). Switzerland and the Länder of Rhineland-Palatinate and Schleswig-Holstein in Germany were the only places in Europe where the communes had a smaller median area than in France. The communes of France's overseas départements such as Réunion and French Guiana are large by French standards. They usually group into

1445-455: Is quite high above France's average and clearly superior to that of the Rhône's drainage basin (666 mm (26.2 in) in Valence for a surface area of 66,450 km (25,660 sq mi)). The specific discharge is 27.9 liters per second per square kilometer of drainage basin. Communes of France The commune ( French pronunciation: [kɔmyn] ) is

1530-711: Is related to the Indo-European *isərós , meaning "impetuous, quick, vigorous," which is similar to the Sanskrit isiráḥ इसिरः อิสิระ with the same definition. It was probably based on the reconstructed Indo-European root *eis(ə) (and not *is ), which incidentally has not been found in the Celtic languages of the British Isles . The word Isara figures in the etymology of many other river names, from ancient Gaul and its neighboring lands. Examples of this are

1615-459: Is still moderate compared to other rivers in the south of France, like the Tarn . The highest instantaneous discharge on record was 2,050 m/s (72,000 cu ft/s) on September 16, 1960, while the highest daily value was 1,510 m/s (53,000 cu ft/s) on October 7 of the same year. The depth of runoff for the Isère's drainage basin is 882 millimeters (34.7 inches) annually, which

1700-402: Is that mergers reduce the number of available elected positions, and thus are not popular with local politicians. Moreover, citizens from one village may be unwilling to have their local services run by an executive located in another village, whom they may consider unaware of or inattentive to their local needs. In December 2010 the law n° 2010-1563 regarding reform of territorial collectivities

1785-516: Is the only administrative unit below the commune in the French Republic but exists only in these three communes. These municipal arrondissements are not to be confused with the arrondissements that are subdivisions of French départements : French communes are considered legal entities , whereas municipal arrondissements, by contrast, have no official capacity and no budget of their own. The rights and obligations of communes are governed by

1870-722: Is the smallest and oldest administrative division in France . " Commune " in English has a historical association with socialist and collectivist political movements and philosophies. This association arises in part from the rising of the Paris Commune (1871) which could have more felicitously been called, in English, "the rising of the City of Paris". There is nothing intrinsically different between "town" in English and commune in French. The French word commune appeared in

1955-774: Is used to describe the meeting of tidal or other non-riverine bodies of water, such as two canals or a canal and a lake. A one-mile (1.6 km) portion of the Industrial Canal in New Orleans accommodates the Gulf Intracoastal Waterway and the Mississippi River-Gulf Outlet Canal ; therefore those three waterways are confluent there. The term confluence can also apply to the process of merging or flowing together of other substance. For example, it may refer to

2040-552: The Code général des collectivités territoriales (CGCT) which replaced the Code des communes (except for personnel matters) with the passage of the law of 21 February 1996 for legislation and decree number 2000-318 of 7 April 2000 for regulations. From 1794 to 1977 — except for a few months in 1848 and 1870-1871 — Paris had no mayor and was thus directly controlled by the departmental prefect. This meant that Paris had less autonomy than certain towns or villages. Even after Paris regained

2125-748: The Grésivaudan . The lower valley constitutes a section of the Plain of Valence  [ fr ] (also called the Valentinois ) and is characterized by the river's deep, winding channel. Instead of widening its banks over time, the Isère has dug deeper into its bed , forming stepped fluvial terraces . The valley has clearly defined borders and is relatively narrow, not exceeding 2 km (1.2 mi) in breadth. The repetition of alluvial deposition (during periods of Quaternary glaciation ) and overdeepening (during interglacial periods), known as

2210-565: The National Assembly ( Assemblée Nationale ) passed a law creating the commune, designed to be the lowest level of administrative division in France, thus endorsing these independently created communes, but also creating communes of its own. In this area as in many others, the work of the National Assembly was, properly speaking, revolutionary: not content with transforming all the chartered cities and towns into communes,

2295-482: The Ordinance of Villers-Cotterêts of 1539 by Francis I , the priest in charge of the parish was also required to record baptisms, marriages, and burials. Except for these tasks, villages were left to handle other issues as they pleased. Typically, villagers would gather to decide over a special issue regarding the community, such as agricultural land usage, but there existed no permanent municipal body. In many places,

2380-631: The United States , with a territory fourteen times larger than that of the French Republic, and nearly five times its population, had 35,937 incorporated municipalities and townships at the 2002 Census of Governments, fewer than that of the French Republic. The number of barangays in the Philippines, villages of Indonesia, and muban in Thailand also have a higher number than the French communes. There have long been calls in France for

2465-604: The VCN3  [ fr ] can drop to 110 m/s (3,900 cu ft/s) during a five-year dry spell, which is very low. On the other hand, severe flooding can result from rapid thaw or torrential autumn rain. In fact, QIX 2  [ fr ] and QIX 5 are 1,200 (42,000) and 1,500 m/s (53,000 cu ft/s), respectively. QIX 10 is 1,700 m/s (60,000 cu ft/s). QIX 20 reaches 1,900 m/s (67,000 cu ft/s), while QIX 50 rises to 2,200 m/s (78,000 cu ft/s), which

2550-444: The mairies . These abrupt changes profoundly alienated devout Catholics, and France soon was plunged into the throes of civil war , with the fervently religious regions of western France at its center. It would take Napoleon I to re-establish peace in France, stabilize the new administrative system, and make it generally accepted by the population. Napoleon also abolished the election of the municipal councils, which now were chosen by

2635-716: The prefect , the local representative of the central government. Today, French communes are still very much the same in their general principles as those that were established at the beginning of the Revolution. The biggest changes occurred in 1831, when the French Parliament re-established the principle of the election of municipal councils, and in 1837 when French communes were given legal "personality", being now considered legal entities with legal capacity. The Jacobin revolutionaries were afraid of independent local powers, which they saw as conservative and opposed to

2720-491: The river mouth . Confluences are studied in a variety of sciences. Hydrology studies the characteristic flow patterns of confluences and how they give rise to patterns of erosion, bars, and scour pools. The water flows and their consequences are often studied with mathematical models . Confluences are relevant to the distribution of living organisms (i.e., ecology ) as well; "the general pattern [downstream of confluences] of increasing stream flow and decreasing slopes drives

In non-Celtic countries, we find the Isarco , a river in Northern Italy, the Éisra and Istrà in Lithuania , Jizera in the Czech Republic and Usora in Bosnia and Herzegovina . The Isère's course measures 286 kilometers (178 miles) and runs through

2890-551: The 12th century, from Medieval Latin communia , for a large gathering of people sharing a common life; from Latin communis , 'things held in common'. As of January 2021, there were 35,083 communes in France , of which 34,836 were in metropolitan France , 129 in the overseas departments , and 83 in the overseas collectivities and New Caledonia . This is a considerably higher total than that of any other European country , because French communes still largely reflect

2975-461: The 1999 census was even smaller, at 10.73 square kilometres (4.14 sq mi). The median area gives a better sense of the size of a typical mainland France commune than the average area since the average includes some very large communes. In Italy , the median area of communes ( comuni ) is 22 km (8.5 sq mi); in Belgium it is 40 km (15 sq mi); in Spain it

3060-401: The 36,683 communes have fewer than 500 inhabitants and, with 4,638,000 inhabitants, these smaller communes constitute just 7.7 percent of the total population. In other words, just 8 percent of the French population live in 57 percent of its communes, whilst 92 percent are concentrated in the remaining 43 percent. Alsace , with an area of 8,280 km (3,200 sq mi), and now part of

3145-565: The National Assembly also decided to turn all the village parishes into full-status communes. The Revolutionaries were inspired by Cartesian ideas as well as by the philosophy of the Enlightenment . They wanted to do away with all the peculiarities of the past and establish a perfect society, in which all and everything should be equal and set up according to reason, rather than by tradition or conservatism. Thus, they set out to establish administrative divisions that would be uniform across

3230-502: The Région Grand Est, used to be the smallest of the regions of metropolitan France , and still has no fewer than 904 communes. This high number is typical of metropolitan France but is atypical when compared with other European countries. It shows the distinctive nature of the French commune as a geo-political or administrative entity. With its 904 communes, Alsace has three times as many municipalities as Sweden , which has

3315-515: The average monthly discharge between 382 (13,500) and 500 m/s (18,000 cu ft/s) from April to July (peaking in May and June), and low water levels in autumn and winter, from August to February, with a minimum average monthly discharge of 246 m/s (8,700 cu ft/s) in September. Generally speaking, this makes the Isère a very plentiful watercourse throughout the year. However,

3400-452: The benefit of poorer suburbs. Moreover, intercommunal structures in many urban areas are still new, and fragile: Tensions exist between communes; the city at the center of the urban area often is suspected of wishing to dominate the suburban communes; communes from opposing political sides also may be suspicious of each other. Two famous examples of this are Toulouse and Paris. In Toulouse, on top of there being six intercommunal structures,

3485-475: The central government's calls for mergers and rationalization. By way of contrast, in the German states bordering Alsace, the geo-political and administrative areas have been subject to various re-organizations from the 1960s onward. In the state of Baden-Württemberg , the number of Gemeinden or communities was reduced from 3,378 in 1968 to 1,108 in September 2007. In comparison, the number of communes in Alsace

3570-410: The chartered cities) suddenly became legal entities for the first time in their history. This is still the case today. During the revolution, approximately 41,000 communes were created, on territory corresponding to the limits of modern-day France (the 41,000 figure includes the communes of the departments of Savoie , Haute-Savoie and Alpes-Maritimes which were annexed in 1795, but does not include

3655-535: The city of Toulouse chartered by the counts of Toulouse). These cities were made up of several parishes (up to c. 50 parishes in the case of Paris), and they were usually enclosed by a defensive wall . They had been emancipated from the power of feudal lords in the 12th and 13th centuries, had municipal bodies which administered the city, and bore some resemblance with the communes that the French Revolution would establish except for two key points: In

3740-544: The country: the whole of France would be divided into départements , themselves divided into arrondissements, themselves divided into cantons, themselves divided into communes, no exceptions. All of these communes would have equal status, they would all have a mayor at their head and a municipal council elected by the inhabitants of the commune. This was a real revolution for the thousands of villages that never had experienced organized municipal life before. A communal house had to be built in each of these villages, which would house

3825-464: The departments of modern-day Belgium and Germany west of the Rhine , which were part of France between 1795 and 1815). This was fewer than the 60,000 parishes that existed before the revolution (in cities and towns, parishes were merged into one single commune; in the countryside, some very small parishes were merged with bigger ones), but 41,000 was still a considerable number, without any comparison in

3910-412: The difference residing in the lack of administrative powers. Except for the municipal arrondissements of its largest cities, the communes are the lowest level of administrative division in France and are governed by elected officials including a mayor ( maire ) and a municipal council ( conseil municipal ). They have extensive autonomous powers to implement national policy. A commune

3995-599: The division of France into villages or parishes at the time of the French Revolution . (1) Within the current limits of metropolitan France, which existed between 1860 and 1871 and from 1919 to today. (2) Within the current extent of overseas France, which has remained unchanged since the independence of the New Hebrides in 1980. The whole territory of the French Republic is divided into communes; even uninhabited mountains or rain forests are dependent on

4080-543: The end of the afternoon, following the storming of the Bastille , the provost of the merchants of Paris, Jacques de Flesselles was shot by the crowd on the steps of Paris City Hall. Although in the Middle Ages the provosts of the merchants symbolized the independence of Paris and even had openly rebelled against King Charles V , their office had been suppressed by the king, then reinstated but with strict control from

4165-480: The fact that there are pronounced differences in size between French communes. As mentioned in the introduction, a commune can be a city of 2 million inhabitants such as Paris, a town of 10,000 inhabitants, or just a hamlet of 10 inhabitants. What the median population tells us is that the vast majority of the French communes only have a few hundred inhabitants, but there are also a small number of communes with much higher populations. In metropolitan France 57 percent of

4250-558: The form of a law on 22 March 1890, which provided for the establishment of single-purpose intercommunal associations. French lawmakers having long been aware of the inadequacy of the communal structure inherited from the French Revolution for dealing with a number of practical matters, the so-called Chevènement law of 12 July 1999 is the most recent and most thoroughgoing measure aimed at strengthening and simplifying this principle. In recent years it has become increasingly common for communes to band together in intercommunal consortia for

4335-587: The form of structural bracing. The velocities and hydraulic efficiencies should be meticulously calculated and can be altered by integrating different combinations of geometries, components such a gradients, cascades and an adequate junction angle which is sympathetic to the direction of the watercourse’s flow to minimise turbulent flow, maximise evacuation velocity and to ultimately maximise hydraulic efficiency. Since rivers often serve as political boundaries, confluences sometimes demarcate three abutting political entities, such as nations, states, or provinces, forming

4420-548: The king, and so they had ended up being viewed by the people as yet another representative of the king, no longer the embodiment of a free municipality. Following that event, a "commune" of Paris was immediately set up to replace the old medieval chartered city of Paris, and a municipal guard was established to protect Paris against any attempt made by King Louis XVI to quell the ongoing revolution. Several other cities of France quickly followed suit, and communes arose everywhere, each with their municipal guard. On 14 December 1789,

4505-437: The kingdom. A parish was essentially a church, the houses around it (known as the village), and the cultivated land around the village. France was the most populous country in Europe at this time, with a population of approximately 25 million inhabitants in the late 18th century ( England in contrast had only 6 million inhabitants), which accounts for the large number of parishes. French kings often prided themselves on ruling over

4590-653: The law. In urban areas, the new intercommunal structures are much more a reality, being created by local decision-makers out of genuine belief in the worth of working together. However, in many places, local feuds have arisen, and it was not possible to set up an intercommunal structure for the whole of the urban area: some communes refusing to take part in it, or even creating their own structure. In some urban areas like Marseille there exist four distinct intercommunal structures! In many areas, rich communes have joined with other rich communes and have refused to let in poorer communes, for fear that their citizens would be overtaxed to

4675-552: The least money per inhabitant, whereas urban communities are given the most money per inhabitant, thus pushing communes to form more integrated communities where they have fewer powers, which they might otherwise have been loath to do if it were not for government money. The Chevènement law has been extremely successful in the sense that a majority of French communes now have joined the new intercommunal structures. On 1 January 2007, there were 2,573 such communities in metropolitan France (including five syndicats d'agglomération nouvelle ,

4760-414: The local feudal lord ( seigneur ) still had a major influence in the village's affairs, collecting taxes from tenant-villagers and ordering them to work the corvée , controlling which fields were to be used and when, and how much of the harvest should be given to him. Additionally, some cities had obtained charters during the Middle Ages, either from the king himself or from local counts or dukes (such as

4845-575: The lowest communes' median population of all the European countries (communes in Switzerland or Rhineland-Palatinate may cover a smaller area, as mentioned above, but they are more populated). This small median population of French communes can be compared with Italy, where the median population of communes in 2001 was 2,343 inhabitants, Belgium (11,265 inhabitants), or even Spain (564 inhabitants). The median population given here should not hide

4930-480: The main community of Toulouse and its suburbs is only a community of agglomeration, although Toulouse is large enough to create an Urban Community according to the law. This is because the suburban communes refused an urban community for fear of losing too much power, and opted for a community of agglomeration, despite the fact that a community of agglomeration receives less government funds than an urban community. As for Paris, no intercommunal structure has emerged there,

5015-466: The maximum allowable pay of the mayor and deputy mayors, and municipal campaign finance limits (among other features) all depend on the population echelon into which a particular commune falls. Since the PLM Law of 1982, three French communes also have a special status in that they are further divided into municipal arrondissements : these are Paris, Marseille , and Lyon . The municipal arrondissement

5100-486: The mayors. Civil marriages were established and started to be performed in the mairie with a ceremony not unlike the traditional one, with the mayor replacing the priest, and the name of the law replacing the name of God (" Au nom de la loi, je vous déclare unis par les liens du mariage. " – "In the name of the law, I declare you united by the bonds of marriage."). Priests were forced to surrender their centuries-old baptism, marriage, and burial books, which were deposited in

5185-425: The meetings of the municipal council as well as the administration of the commune. Some in the National Assembly were opposed to such a fragmentation of France into thousands of communes, but eventually Mirabeau and his ideas of one commune for each parish prevailed. On 20 September 1792, the recording of births, marriages, and deaths also was withdrawn as a responsibility of the priests of the parishes and handed to

Usually, there was no mayor in the modern sense; all the échevins or consuls were on equal footing, and rendered decisions collegially. However, for certain purposes, there

5355-523: The number of communes in the process – the Gemeinden of West Germany were decreased from 24,400 to 8,400 in the space of a few years – France only carried out mergers at the margin, and those were mostly carried out during the 19th century. From 41,000 communes at the time of the French Revolution, the number decreased to 37,963 in 1921, to 36,569 in 2008 (in metropolitan France). Thus, in Europe, only Switzerland has as high

5440-404: The number of municipalities compared to the large and populous state of North Rhine-Westphalia (396 Gemeinden in September 2007). Despite differences in population, each of the communes of the French Republic possesses a mayor ( maire ) and a municipal council ( conseil municipal ), which jointly manage the commune from the municipal hall ( mairie ), with exactly the same powers no matter

5525-631: The only partially successful statute enacted in 1966 and enabling urban communes to form urban communities or the more marked failure of the Marcellin law of 1971, the Chevènement law met with a large measure of success, so that a majority of French communes are now involved in intercommunal structures. There are two types of these structures: In exchange for the creation of a community, the government allocates money to them based on their population, thus providing an incentive for communes to team up and form communities. Communities of communes are given

5610-403: The place of the former communes, which are represented by a delegated mayor and a delegated council. Between 2012 and 2021, about 820 communes nouvelles have been established, replacing about 2,550 old communes. The expression "intercommunality" ( intercommunalité ) denotes several forms of cooperation between communes. Such cooperation first made its appearance at the end of the 19th century in

5695-545: The point where a tributary joins a larger river ( main stem ); or where two streams meet to become the source of a river of a new name (such as the confluence of the Monongahela and Allegheny rivers, forming the Ohio River ); or where two separated channels of a river (forming a river island ) rejoin at the downstream end. The point of confluence where the channel flows into a larger body of water may be called

5780-541: The populations and land of the geographic area covered. The communes are the fourth-level administrative divisions of France. Communes vary widely in size and area, from large sprawling cities with millions of inhabitants like Paris , to small hamlets with only a handful of inhabitants. Communes typically are based on pre-existing villages and facilitate local governance. All communes have names, but not all named geographic areas or groups of people residing together are communes ( "lieu dit" or "bourg" ),

5865-495: The provision of such services as refuse collection and water supply. Suburban communes often team up with the city at the core of their urban area to form a community charged with managing public transport or even administering the collection of local taxes. The Chevènement law tidied up all these practices, abolishing some structures and creating new ones. In addition, it offered central government finance aimed at encouraging further communes to join in intercommunal structures. Unlike

Therefore, when they created the communes, they deprived them of any legal "personality" (as they did with the départements ), with only the central state having legal "personality." By 1837 that situation was judged impractical, as mayors and municipal councils could not be parties in courts. The consequence of the change, however, was that tens of thousands of villages which had never had legal "personality" (contrary to

6035-469: The right to elect its own mayor in 1977, the central government retained control of the Paris police. In all other French communes, the municipal police are under the mayor's supervision. French communes were created at the beginning of the French Revolution in 1789–1790. Before the revolution, France's lowest level of administrative division was the parish ( paroisse ), and there were up to 60,000 of them in

6120-526: The river is made up of several zones: The flow of the Isère was observed over a period of 58 years (between 1956 and 2015) at Beaumont-Monteux in the Drôme department, situated near the river's confluence with the Rhône. The discharge of the river at Beaumont-Monteux measured 329 cubic meters per second (11,600 cubic feet per second). The Isère's large seasonal fluctuations are typical of rivers fed in large part by snowmelt , with springtime flooding raising

6205-406: The same as those designed at the time of the French Revolution more than 200 years ago, with the same limits. Countless rural communes that had hundreds of inhabitants at the time of the French Revolution now have only a hundred inhabitants or fewer. On the other hand, cities and towns have grown so much that their urbanized area is now extending far beyond the limits of their commune which were set at

6290-403: The same commune several villages or towns, often with sizeable distances among them. In Réunion, demographic expansion and sprawling urbanization have resulted in the administrative splitting of some communes . The median population of metropolitan France's communes at the 1999 census was 380 inhabitants. Again this is a very small number, and here France stands absolutely apart in Europe, with

6375-453: The sites for fortified triangular temples, where they practiced human sacrifice and other sacred rites. In Hinduism , the confluence of two sacred rivers often is a pilgrimage site for ritual bathing. In Pittsburgh, a number of adherents to Mayanism consider their city's confluence to be sacred. Mississippi basin Atlantic watersheds Pacific watersheds Occasionally, "confluence"

6460-414: The size of the commune. This uniformity of status is a legacy of the French Revolution, which wanted to do away with the local idiosyncrasies and tremendous differences in status that existed in the kingdom of France. French law makes allowances for the vast differences in commune size in a number of areas of administrative law. The size of the municipal council, the method of electing the municipal council,

6545-642: The southern tip of La Roche-de-Glun (a commune on an island formed by the canal), the Isère Dam drains part of the water back into the Rhône and permits the Isère to continue its course alone until it passes through the Bourg-lès-Valence Dam and reaches its final junction with the Rhône. (L) Left-bank tributary ; (R) Right-bank tributary . The length of the Isère is 286 km (178 mi), and its drainage basin covers 11,890 km (4,590 sq mi). The vertical profile of

6630-613: The subsequent transport of metals downstream of the mixing zone." A natural phenomenon at confluences that is obvious even to casual observers is a difference in color between the two streams; see images in this article for several examples. According to Lynch, "the color of each river is determined by many things: type and amount of vegetation in the watershed, geological properties, dissolved chemicals, sediments and biologic content – usually algae ." Lynch also notes that color differences can persist for miles downstream before they finally blend completely. Hydrodynamic behaviour of flow in

6715-420: The suburbs of Paris fearing the concept of a "Greater Paris", and so disunity still is the rule in the metropolitan area, with the suburbs of Paris creating many different intercommunal structures all without the city. Confluence In geography , a confluence (also: conflux ) occurs where two or more watercourses join to form a single channel . A confluence can occur in several configurations: at

6800-401: The system to ensure the longevity and efficiency of the structure. Engineers have to design these systems whilst considering a list of factors that ensure the discharge point is structurally stable as the entrance of the lateral culvert into the main structure may compromise the stability of the structure due to the lack of support at the discharge, this often constitutes additional supports in

6885-609: The time of the revolution. The most extreme example of this is Paris, where the urbanized area sprawls over 396 communes. Paris in fact was one of the very few communes of France whose limits were extended to take into account the expansion of the urbanized area. The new, larger, commune of Paris was set up under the oversight of Emperor Napoléon III in 1859, but after 1859 the limits of Paris rigidified. Unlike most other European countries, which stringently merged their communes to better reflect modern-day densities of population (such as Germany and Italy around 1970), dramatically decreasing

6970-580: The world at the time, except in the empire of China (but there, only county level and above had any permanent administration). Since then, tremendous changes have affected France, as they have the rest of Europe: the Industrial Revolution , two world wars , and the rural exodus have all depopulated the countryside and increased the size of cities. French administrative divisions, however, have remained extremely rigid and unchanged. Today about 90 percent of communes and departments are exactly

7055-428: Was adopted, which created the legal framework for the communes nouvelles (lit. "new communes"). A commune nouvelle can be created by merger of a number of communes at the request of the municipal councils of all the communes or at the initiative of the state representative in the department (the prefect ). The municipal council of the new commune can decide to create communes déléguées (lit. "delegated communes") in

7140-1053: Was one échevin or consul ranking above the others, a sort of mayor, although not with the same authority and executive powers as a modern mayor. This "mayor" was called provost of the merchants ( prévôt des marchands ) in Paris and Lyon; maire in Marseille, Bordeaux, Rouen , Orléans , Bayonne and many other cities and towns; mayeur in Lille ; premier capitoul in Toulouse; viguier in Montpellier ; premier consul in many towns of southern France; prêteur royal in Strasbourg ; maître échevin in Metz ; maire royal in Nancy ; or prévôt in Valenciennes . On 14 July 1789, at

7225-555: Was only reduced from 946 in 1971 (just before the Marcellin law aimed at encouraging French communes to merge with each other was passed, see Current debate section below) to 904 in January 2007. Consequently, the Alsace region—despite having a land area only one-fifth the size and a total population only one-sixth of that of its neighbor Baden-Württemberg—has almost as many municipalities. The small Alsace region has more than double
