Chambourg-sur-Indre
Chambourg-sur-Indre is a French commune the department of Indre-et-Loire in the region of Centre-Val de Loire.
Perhaps already occupied in the Neolithic era, the site was colonized at the time of the Roman Empire; witnessed by many traces of an aqueduct, a Roman villa, a Roman road. Hosting a Viguerie and a medieval fief, Chambourg became a commune in 1789, following an exchange of hamlets hitherto undivided with its neighbor Chédigny. Flooding of the Indre, always to be feared in 2014, has not deterred people from settling permanently in Chambourg on the banks of the river.
Formed as Chambourg-sur-Indre in 1920, the town is one of the few rural areas of Lochois that as not experienced population decline in the 20th century. In 2011, its population was 1,317. Over the last 30 years, agriculture in the community has refocused around large farms specializing in the cultivation of cereals, oil seeds and protein crops. In industry, since 1961, Chambourg-sur-Indre has welcomed a major French company in the field of traffic signs.
Between the Gâtine of Loches plateau, the Loches forest and the Indre valley, Chambourg has in its territory varied wildlife worthy of being partially integrated with multiple national conservation efforts including and for the assessment and protection of biodiversity.
Geography
Location and surrounding communities
The town of Chambourg-sur-Indre is located in the southeast quadrant of the Indre-et-Loire department, in the historical region of Touraine. Chambourg-sur-Indre is located at southeast of Tours, as the crow flies prefecture of the Indre-et-Loire department is north in Loches.Geology and topology
The main geological formation Chambourg-sur-Indre is Cenomanian sandstone, deposited about 95 million years ago by a sea that covered Touraine. Deposits laid on top of this are a yellow Turonian limestone , then a layer of Senonian chalk ; the sea receded at the end of this period, which corresponds to the end of Mesozoic ear. In the northwest corner of the commune, a different seas deposited the limestone lake in the middle and the end of the Eocene epoch, characteristic of the small fertile agricultural region of Champeigne tourangelle. The rest of the plateau is irregularly covered with loess from the Quaternary period, forms an infertile soil called "bournais". The valleys of the Indre and its tributaries, which have cut the base of the limestone plateau during alternating glacial and interglacial periods of the Pleistocene, are covered with recent alluvium, giving the soil a hydromorphous tendency, often with a shallow water table. The slopes between the plateau and the valleys are eroded washed silt or gravel deposits and clay from the Turonian and Senonian strata; this type of soil is called "perruche" in the Loire Valley.The land area of Chambourg-sur-Indre is 2,839 hectares, the average area of a French commune being 1,510.2 hectare.
The altitude of this area varies between and. The lowest point is on the edge of Indre within the municipal boundary of Azay-sur-Indre and the highest is on the west plateau, bordering Chanceaux-près-Loches and Dolus-le-Sec.
Natural landscapes
Woods and forests are still present in Chambourg-sur-Indre where they still account for about a fifth of the total area of the municipality. They are found in the east, near Saint-Quentin-sur-Indrois and Ferrière-sur-Beaulieu, as in the west, where they form a band from commune headquarters to the municipal boundary with Chanceaux-près-Loches. The broad valley of the Indre offers a landscape of meadows, most of which are flooded during flood periods, bordered by groves of poplars to enhance area once covered in grass. The rest of the municipality, namely non-forested parts of the plateau adjoining the Indre Valley by wooded slopes, dedicated to agriculture, of an average fertility, except for the extreme north-western tip of the town, established in Champeigne "a locality there besides that name", with much more favorable agronomic characteristics.Waterways
The municipality of Chambourg-sur-Indre is crossed from south-southeast to north-north-east by the Indre river which cut into the plateau a broad valley about wide. At the bottom of this valley, and due to its shallow slope, the Indre navigates many bends and oxbow lakes, even forming downstream of the urban core Chambourg-sur-Indre, two separate lakes enclosing an island. Indre is fed with a half-dozen streams originating on the plateau to the left side or in the forest of Loches for the right bank. Their courses are usually perpendicular to that of the Indre, including at their confluence. Floods of the Indre are of the flood plain type, threatening areas of the town built closer to the river.The Indre is mentioned for the first time by Gregory of Tours in the 6th century under the name fluvium Angerem". This name is often attributed to a change in the Frankish language anger from the root ang- or 'angr-.
Climate
The geographical location of Chambourg-sur-Indre gives it a temperate ocean climate; The coast at Rochelle is away "as the crow flies". This type of climate, subject to prevailing westerly flow over the year is characterized by mild temperatures, the average monthly minimum is never below freezing, even in winter, while in summer it is common to have a heatwave for a few days. No month is truly dry, average monthly rainfall is always greater than.Below are the meteorological data for Tours Station.
Around these average values, we sometimes observe substantial differences, having an unsurpassed record 2012; thus the 10 August 2003, during the European heat wave, the maximum temperature was observed ; the lowest temperature ever recorded in Tours is on 29 December 1964; a record rainfall of was recorded in 1999.
Comparing averages from the thirty stations in Tours appears to highlight a certain level rise of temperatures on the three reference periods; the sunshine and precipitation parameters do not change noticeably.

It is also possible to go from Loches Chambourg using the D25 along the right bank of the Indre between the Island Thimée and Corbery.City planning
City changes
The urban center of Chambourg-sur-Indre is grouped around the pole formed by the church and the town hall from the intersection of the D94 and D17. The site overlooks by the left side of the Indre Valley flowing northeast, is immune to flooding. The town has expanded since 1980 as subdivisions are built along new roads, west and east of the town in recent projects, being established more directly in the bottom of the valley of the Indre. To the west of the town is business district. Once having crossed the series of three bridges that cross the D94 to the Indre valley towards the northeast and Chédigny we find Thimée Island, an important hamlet also benefiting from new construction, with the town center hanging somehow on the right bank of the Indre.Several other villages, mostly located at the foot of the hill on the right bank of the Indre, are experiencing the same level of development. Part of the area situated on the plateau on the right bank of the Indre is much less populated, with the exception of "one-road town" built not far from the castle Marray on a promontory surrounded by the valleys of two parallel streams, tributaries of the left bank of the Indre.

Major natural hazards
On 28 April 2005, the prefecture of Indre-et-Loire adopted a plan to prevent flooding for all municipalities in the Indre department, which includes Chambourg-sur-Indre; accordingly, the land located in the Chambourg extreme flood hazard zone are unsuitable for. A :fr:Arrêté en France|prefectural order dated 29 April 2011 specifies the nature of natural hazards to which Chambourg-sur-Indre is subject; they are of two types: flooding due to an overflow of the Indre or flooding from storm water runoff. The same document details the decrees of acknowledgment of natural disasters made between 1983 and 2011 for the municipality of Chambourg-sur-Indre, two decrees for floods and mudslides, two decrees for landslides following a drought and one decree for floods, mudslides and landslides. This paper also indicates that Chambourg-sur-Indre is located in a low risk earthquake zone: level 2 on a scale of 1–5.The risk of landslides after drought is due to the successive phases of shrinking and swelling clays could undermine the foundations of buildings. All of the plateau of Chambourg-sur-Indre, on both sides of the Indre, is subject to a "medium" or "strong" rating for this risk, while in the valley of the Indre, this risk is considered "lower" or "a priori", according to the scale defined by the.
Name origin
The place name Chambourg appears for the first time in the founding charter of the abbey of Cormery from 791 as Condita Cambortensis. In the tenth century, villa Cambort was used, Chamborc' ' in the ecclesiastical register of Tours from 1290 or Chambourt in a cartulary of chartreuse du Liget in 1304.As shown in the older forms, it is kind Gallic name Cambo-ritu, based on two Celtic roots cambo- and rito, ritu, hence the overall sense of "stepping into the curve" or "ford of the meander". The etymology continued to change to, among others, Château de Chambord or Chambors. Indeed, the element ritu- preceded by -o-, has led to a regular termination -or- written variously as -ort, -ors or -ord. Chambort was reinterpreted Cham-bourg by analogy with the term bourg in the Middle Ages.
The current spelling appears in the Cassini map; the final name of the town, Chambourg-sur-Indre was fixed by the order of 23 August 1920, the complementary suffix 'sur-Indre' avoiding possible confusion elsewhere with the same name.
The names l'Île Thimée and l'Île Auger'' refers to a time when these place names, were in the area of the Indre; this is no longer the case in modern times. According to written sources, both spellings "isle" or "île" are used indiscriminately. In this article, the modern spelling is used.
History
Prehistory and early history
The oldest traces of human presence on the site Chambourg-sur-Indre manifest themselves in the form of a racloir, a typical tool of Mousterian, found by chance during a survey of soil in the forest of Loches; Neolithic tools were also found. We presume the existence of a Neolithic settlement at a place called "Chatres". The possible origin of the place name in the Gallo-Roman CASTRU and the layout "limited to a promontory east through the valley of the Indre and north and south by the courts of two of its tributaries streams" suggest the existence of a promontory fort; however, no excavation has yet verified the validity of this hypothesis.Antiquity
The Gallo-Roman site at Cornillé, on the left bank of the Indre upstream of the town contains reticulated walls that were still visible at the beginning of the nineteenth century, and a hypocaust and the remains of an aqueduct; in 2014 the only remaining portions of walls in basements. This site was perhaps that of a mansio. On the right bank of the Indre, between Corbery and Auger Island on Chambourg-sur-Indre, D25 follows almost exactly an ancient road which continued in antiquity to Azay-sur-Indre beyond the Thimée Island without leaving the right bank of the Indre. Coins bearing the image of the emperors Nero, who reigned from 54 to 68, and Septimius Severus were discovered in the town, on the site of a domus There is a medieval bridge on Auger Island nicknamed "Roman bridge" on many documents and on the signs.Middle ages
Chambourg was promoted to the rank of Viguerie in the ninth century; while these honors were often temporary, Chambourg Viguerie, whose existence is supported for more than a century and a half, was an exception, or at least a rarity. At the end of the tenth century early eleventh century, the Count of Anjou and the house of Blois fought over Touraine, snatching and taking each other's territories. No document seems to mention such problems for Chambourg. In the Middle Ages, Chambourg was a fief, subordinate to Castle Bray, which was named at that time, Reignac-sur-Indre in the thirteenth to fifteenth centuries.From modern day to the Empire
In the seventeenth century, Chambourg was one of eighteen priories subject to the Benedictine Abbey of Cormery. However, the monks of the Beaulieu-lès-Loches Abbey collected taxes on Also, in the seventeenth century, several titled aristocrats arrived in the area of Chambourg. The forest of Loches was considered a rich source of food for it contains game, chestnuts, honey, the firewood and lumber that provides for heating and buioling, and any offense committed against the forest was severely punished; between 1750 and 1790, several residents of the Auger Island and other villages in Chambourg were arrested for illegal logging of 60 oaks in the massive forest of Loches, and of other timber theft.Until the French Revolution, some hamlets close to the boundary between the parishes of St. Martin and St. Chambourg Michel Chédigny, which hamlets were called "turning and twisting", that is to say, they were subject to one or the other parish, alternating annually, had at its center, a complex system of financial compensation between the parishes concerned. This ended with the creation of the commune on December 14, 1789 and the delimitation of their territories; these hamlets were then attached permanently to Chambourg, or Chédigny.
Modern day
The creation of the railway line connecting Tours Châteauroux, opened between Joué-lès-Tours and Loches in 1879 with the creation of a stop in Chambourg in 1879 can be considered a milestone for the town ; at the time when the rural exodus began to be felt in the villages, it limited the impact to Chambourg allowing the inhabitants of the town to continue to live there, or even to settle in town while working Tours, but especially Loches. This demographic dynamic was reinforced by the installation at the beginning of the 20th century, businesses related to agriculture, mills on the Indre and grain storage silos, the latter taking advantage of the proximity of rail service. These companies gradually disappeared in the second half of the 20th century but were replaced by others, such as a large road sign factory located in Chambourg since 1961 which has more than one hundred employees.Forty-eight Chambourgeois died in combat during World War I, or about one out of 20.
On June 19, 1940, when German troops were reported in the eastern department, the French army was trying to slow their advance by blowing up the bridges over the Indre, including Chambourg. Between June 22, 1940 and 28 February 1943, the demarcation line ran north–south in the town of Le Château-le-Sec, bordering Chambourg-sur-Indre on the west: Chambourg-sur-Indre was in zone libre, but only a few kilometers from the line; the municipality was rejoined on 28 February 1943 to the prefecture of Indre. As early as June 1940, the prefect of Indre replaced the elected mayor by a special delegation of four members who served until October 1944. In the last decade of August 1944, German troops gradually withdrew to the north and east of the department after Loches was recaptured they had to leave for a few days. Their headquarters was temporarily set up in St. Valentin, a hamlet of Chambourg near the municipal boundary with Loches.

Population and society
DemographicsTranslator's note: The format for populations pyramids in the French Wikipedia is different from the English (which requires five year increments). The translator invites a willing party to research the population ages in five year increments and a population pyramid similar to the one in the French article.
The people of Chambourg-sur-Indre are called 'Chambourgeois'.In 1687, the parish registers indicated that Chambourg had 187 feu fiscal, then 208 units in 1789, the last known value before the first census in population.
In 2011, the municipality had 1317 inhabitants. The changing number of inhabitants is known throughout the population census carried out in the town since 1793. From the twenty-first century, the actual census of municipalities with fewer than 10,000 inhabitants are held every five years, in contrast to other cities that have a survey every year.
In contrast to many rural communities, Chambourg-sur-Indre has not experienced a mass exodus during the 20th century; its population has nearly doubled since the French Revolution and increased by nearly 70% between 1975 and 2011, an average gain of 15 inhabitants per year over this period. Examination of the pyramid shows a real lack of population in the age group of 15 29 years, men and women, compared to the county average, while the portion 45–59 years is overrepresented.
Demographic change is due, during the period 1982 - 2010, to both natural growth at net migration, both positive; However, if during the decade 1982 -1990 the net migration accounts for the largest share in the increase in population in the first decade of the 21st century, the increase in population is mainly due to natural increase, as shown by the data in the table below.
| 1982 - 1990 | 1990 - 1999 | 1999 - 2010 | |
| Annual rate of population change | + 2,9 | + 1,1 | + 0,7 |
