A river mouth is the part of a river where the river debouches into another river, a lake, a reservoir, a sea, or an ocean. The water from a river can enter the receiving body in a variety of different ways; the motion of a river is influenced by the relative density of the river compared to the receiving water, the rotation of the earth, any ambient motion in the receiving water, such as tides or seiches. If the river water has a higher density than the surface of the receiving water, the river water will plunge below the surface; the river water will either form an underflow or an interflow within the lake. However, if the river water is lighter than the receiving water, as is the case when fresh river water flows into the sea, the river water will float along the surface of the receiving water as an overflow. Alongside these advective transports, inflowing water will diffuse. At the mouth of a river, the change in flow condition can cause the river to drop any sediment it is carrying; this sediment deposition can generate a variety of landforms, such as deltas, sand bars and tie channels.
Many places in the United Kingdom take their names from their positions at the mouths of rivers, such as Plymouth and Great Yarmouth. Confluence River delta Estuary Liman
Spain the Kingdom of Spain, is a country located in Europe. Its continental European territory is situated on the Iberian Peninsula, its territory includes two archipelagoes: the Canary Islands off the coast of Africa, the Balearic Islands in the Mediterranean Sea. The African enclaves of Ceuta, Peñón de Vélez de la Gomera make Spain the only European country to have a physical border with an African country. Several small islands in the Alboran Sea are part of Spanish territory; the country's mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with Gibraltar. With an area of 505,990 km2, Spain is the largest country in Southern Europe, the second largest country in Western Europe and the European Union, the fourth largest country in the European continent. By population, Spain is the fifth in the European Union. Spain's capital and largest city is Madrid. Modern humans first arrived in the Iberian Peninsula around 35,000 years ago. Iberian cultures along with ancient Phoenician, Greek and Carthaginian settlements developed on the peninsula until it came under Roman rule around 200 BCE, after which the region was named Hispania, based on the earlier Phoenician name Spn or Spania.
At the end of the Western Roman Empire the Germanic tribal confederations migrated from Central Europe, invaded the Iberian peninsula and established independent realms in its western provinces, including the Suebi and Vandals. The Visigoths would forcibly integrate all remaining independent territories in the peninsula, including Byzantine provinces, into the Kingdom of Toledo, which more or less unified politically and all the former Roman provinces or successor kingdoms of what was documented as Hispania. In the early eighth century the Visigothic Kingdom fell to the Moors of the Umayyad Islamic Caliphate, who arrived to rule most of the peninsula in the year 726, leaving only a handful of small Christian realms in the north and lasting up to seven centuries in the Kingdom of Granada; this led to many wars during a long reconquering period across the Iberian Peninsula, which led to the creation of the Kingdom of Leon, Kingdom of Castile, Kingdom of Aragon and Kingdom of Navarre as the main Christian kingdoms to face the invasion.
Following the Moorish conquest, Europeans began a gradual process of retaking the region known as the Reconquista, which by the late 15th century culminated in the emergence of Spain as a unified country under the Catholic Monarchs. Until Aragon had been an independent kingdom, which had expanded toward the eastern Mediterranean, incorporating Sicily and Naples, had competed with Genoa and Venice. In the early modern period, Spain became the world's first global empire and the most powerful country in the world, leaving a large cultural and linguistic legacy that includes more than 570 million Hispanophones, making Spanish the world's second-most spoken native language, after Mandarin Chinese. During the Golden Age there were many advancements in the arts, with world-famous painters such as Diego Velázquez; the most famous Spanish literary work, Don Quixote, was published during the Golden Age. Spain hosts the world's third-largest number of UNESCO World Heritage Sites. Spain is a secular parliamentary democracy and a parliamentary monarchy, with King Felipe VI as head of state.
It is a major developed country and a high income country, with the world's fourteenth largest economy by nominal GDP and sixteenth largest by purchasing power parity. It is a member of the United Nations, the European Union, the Eurozone, the Council of Europe, the Organization of Ibero-American States, the Union for the Mediterranean, the North Atlantic Treaty Organization, the Organisation for Economic Co-operation and Development, Organization for Security and Co-operation in Europe, the Schengen Area, the World Trade Organization and many other international organisations. While not an official member, Spain has a "Permanent Invitation" to the G20 summits, participating in every summit, which makes Spain a de facto member of the group; the origins of the Roman name Hispania, from which the modern name España was derived, are uncertain due to inadequate evidence, although it is documented that the Phoenicians and Carthaginians referred to the region as Spania, therefore the most accepted etymology is a Semitic-Phoenician one.
Down the centuries there have been a number of accounts and hypotheses: The Renaissance scholar Antonio de Nebrija proposed that the word Hispania evolved from the Iberian word Hispalis, meaning "city of the western world". Jesús Luis Cunchillos argues that the root of the term span is the Phoenician word spy, meaning "to forge metals". Therefore, i-spn-ya would mean "the land where metals are forged", it may be a derivation of the Phoenician I-Shpania, meaning "island of rabbits", "land of rabbits" or "edge", a reference to Spain's location at the end of the Mediterranean. The word in question means "Hyrax" due to Phoenicians confusing the two animals. Hispania may derive from the poetic use of the term Hesperia, reflecting the Greek perception of Italy as a "western land" or "land of the setting sun" (Hesperia
Valladolid is a city in Spain and the de facto capital of the autonomous community of Castile and León. It has a population of 309,714 people, making it Spain's 13th most populous municipality and northwestern Spain's biggest city, its metropolitan area ranks 20th in Spain with a population of 414,244 people in 23 municipalities. The city is situated at the confluence of the Pisuerga and Esgueva rivers 15 km before they join the Duero, located within five winegrowing regions: Ribera del Duero, Toro, Tierra de León, Cigales. Valladolid was settled in pre-Roman times by the Celtic Vaccaei people, the Romans themselves, it remained a small settlement until being re-established by King Alfonso VI of Castile as a Lordship for the Count Pedro Ansúrez in 1072. It grew to prominence in the Middle Ages as the seat of the Court of Castile and being endowed with fairs and different institutions as a collegiate church, Royal Court and Chancery and the Royal Mint; the Catholic Monarchs, Isabel I of Castile and Ferdinand II of Aragon, married in Valladolid in 1469 and established it as the capital of the Kingdom of Castile and of united Spain.
Christopher Columbus died in Valladolid in 1506, while authors Francisco de Quevedo and Miguel de Cervantes lived and worked in the city. The city was the capital of Habsburg Spain under Phillip III between 1601 and 1606, before returning indefinitely to Madrid; the city declined until the arrival of the railway in the 19th century, with its industrialisation into the 20th century. The Old Town is made up of a variety of historic houses, churches, plazas and parks, includes the National Museum of Sculpture, the Museum of Contemporary Art Patio Herreriano or the Oriental Museum, as well as the houses of José Zorrilla and Cervantes which are open as museums. Among the events that are held each year in the city there is Holy Week, Valladolid International Film Week, the Theatre Festival and street arts. There is no direct evidence for the origin of the modern name of Valladolid. One held etymological theory suggests that the modern name Valladolid derives from the Celtiberian language expression Vallis Tolitum, meaning "valley of waters", referring to the confluence of rivers in the area.
Another theory suggests that the name derives from the Arabic expression Balad al-Walid بلد الوليد, which means "city of al-Walid", referring to Al-Walid I. Yet a third claims that it derives from Vallis Olivetum, meaning "valley of the olives". Instead, in the south part of the city exist an innumerable amount of pine trees; the gastronomy reflect the importance of the piñon as a local product, not olives. In texts from the middle ages the town is called Vallisoletum, meaning "sunny valley", a person from the town is a Vallisoletano, o Vallisoletana; the city is popularly called Pucela, a nickname whose origin is not clear, but may refer to knights in the service of Joan of Arc, known as La Pucelle. Another theory is that Pucela comes from the fact that Pozzolana cement was sold there, the only city in Spain that sold it; the Vaccaei were a Celtic tribe, the first people with stable presence on the sector of the middle valley of the River Duero documented in historical times. Remains of Celtiberian and of a Roman camp have been excavated near the city.
The nucleus of the city was located in the area of the current San Miguel y el Rosarillo square, was surrounded by a palisade. Archaeological proofs of the existence of three ancient lines of walls have been found. During the time of Muslim rule in Spain the Christian kings moved the population of this region north into more defended areas, deliberately created a no man's land as a buffer zone against further Moorish conquests; the area was captured from the Moors in the 10th century, Valladolid was a village until King Alfonso VI of León and Castile donated it to Count Pedro Ansúrez in 1072. He built a palace for himself and his wife, Countess Eylo, the Collegiate of St. Mary and the La Antigua churches. In the 12th and 13th centuries, Valladolid grew thanks to the commercial privileges granted by the kings Alfonso VIII and Alfonso X, as well as to the repopulation of the area after the Reconquista. In 1469 Queen Isabella I of Castile and King Ferdinand of Aragon were married in the city. In 1506 Christopher Columbus died in Valladolid "still convinced that he had reached the Indies" in a house, now a Museum dedicated to him.
It was made the capital of the kingdom again between 1601 and 1606 by Philip III. The city was again damaged by a flood of the rivers Esgueva. Despite the damage to the old city by the 1960s economic boom, it still boasts a few architectural manifestations of its former glory; some monuments include the unfinished cathedral, the Plaza Mayor, the model for that of Madrid, of other main squares throughout the former Spanish Empire, the National Sculpture Museum, next to the church of Saint Paul, which includes Spain's greatest collections of polychrome wood sculptures, the Faculty of Law of the University of Valladolid, whose façade is one of the few surviving works by Narciso Tomei, the same artist who did the transparente in Toledo Cathedral. The Science Museum is next to the river Pisuerga; the only surviving house of Miguel de Cervantes is located in Valladolid. Although unfinished, the Cathedral of Valladolid was designed by Juan de Herrera, architect of El Escorial. At an elevation of 735 metres or 2,411 feet, the city of Valladolid experiences a hot-summer Medi
Province of Palencia
Palencia is a province of northern Spain, in the northern part of the autonomous community of Castile and León in the northwest of the Iberian Peninsula. It is bordered by the provinces of León, Cantabria and Valladolid. Of the population of 176,125, 45% live in the capital, Palencia, located on the Canal de Castilla. There are 191 municipalities in the province, of which more than half are villages with fewer than 200 people; the major towns in this province are: an industrial-mining town. During the Middle Ages, the Visigoths ruled Palencia. Basílica de San Juan, the oldest Visigothic church in Spain, was built in 661 in the province's Baños de Cerrato. During the thirteenth century a university was founded in the province, it was one of the first in the world. It was shifted to Valladolid; the province is bordered on the north by Cantabria, on the west by the province of León, on the east by the province of Burgos and on the south by the province of Valladolid. In Palencia large protected areas such as the Natural Park of Fuentes Carrionas and Fuente Cobre-Montaña Palencia are located.
The term historical region in Palencia, refers to those regions created in the fourteenth century, under the name merindades. Cantabrian Mountains are located in the northerns parts of the province; the 8,268 feet high Curavacas peak is located in the province. The major commercial products produced in the province are barley, sugar beets, hemp and woolen clothes, leather and rugs. Food processing and metallurgy are major industries; the province has three judicial districts–one each in Palencia, Carrión de los Condes and Cervera de Pisuerga.

A river is a natural flowing watercourse freshwater, flowing towards an ocean, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, brook and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the hydrological cycle. Potamology is the scientific study of rivers, while limnology is the study of inland waters in general. Most of the major cities of the world are situated on the banks of rivers, as they are, or were, used as a source of water, for obtaining food, for transport, as borders, as a defensive measure, as a source of hydropower to drive machinery, for bathing, as a means of disposing of waste.
A river begins at a source, follows a path called a course, ends at a mouth or mouths. The water in a river is confined to a channel, made up of a stream bed between banks. In larger rivers there is also a wider floodplain shaped by flood-waters over-topping the channel. Floodplains may be wide in relation to the size of the river channel; this distinction between river channel and floodplain can be blurred in urban areas where the floodplain of a river channel can become developed by housing and industry. Rivers can flow down mountains, through valleys or along plains, can create canyons or gorges; the term upriver refers to the direction towards the source of the river, i.e. against the direction of flow. The term downriver describes the direction towards the mouth of the river, in which the current flows; the term left bank refers to the left bank in the direction of right bank to the right. The river channel contains a single stream of water, but some rivers flow as several interconnecting streams of water, producing a braided river.
Extensive braided rivers are now found in only a few regions worldwide, such as the South Island of New Zealand. They occur on peneplains and some of the larger river deltas. Anastamosing rivers are quite rare, they have multiple sinuous channels carrying large volumes of sediment. There are rare cases of river bifurcation in which a river divides and the resultant flows ending in different seas. An example is the bifurcation of Nerodime River in Kosovo. A river flowing in its channel is a source of energy which acts on the river channel to change its shape and form. In 1757, the German hydrologist Albert Brahms empirically observed that the submerged weight of objects that may be carried away by a river is proportional to the sixth power of the river flow speed; this formulation is sometimes called Airy's law. Thus, if the speed of flow is doubled, the flow would dislodge objects with 64 times as much submerged weight. In mountainous torrential zones this can be seen as erosion channels through hard rocks and the creation of sands and gravels from the destruction of larger rocks.
A river valley, created from a U-shaped glaciated valley, can easily be identified by the V-shaped channel that it has carved. In the middle reaches where a river flows over flatter land, meanders may form through erosion of the river banks and deposition on the inside of bends. Sometimes the river will cut off a loop, shortening the channel and forming an oxbow lake or billabong. Rivers that carry large amounts of sediment may develop conspicuous deltas at their mouths. Rivers whose mouths are in saline tidal waters may form estuaries. Throughout the course of the river, the total volume of water transported downstream will be a combination of the free water flow together with a substantial volume flowing through sub-surface rocks and gravels that underlie the river and its floodplain. For many rivers in large valleys, this unseen component of flow may exceed the visible flow. Most but not all rivers flow on the surface. Subterranean rivers flow underground in caverns; such rivers are found in regions with limestone geologic formations.
Subglacial streams are the braided rivers that flow at the beds of glaciers and ice sheets, permitting meltwater to be discharged at the front of the glacier. Because of the gradient in pressure due to the overlying weight of the glacier, such streams can flow uphill. An intermittent river only flows and can be dry for several years at a time; these rivers are found in regions with limited or variable rainfall, or can occur because of geologic conditions such as a permeable river bed. Some ephemeral rivers flow during the summer months but not in the winter; such rivers are fed from chalk aquifers which recharge from winter rainfall. In England these rivers are called bournes and give their name to places such as Bournemouth and Eastbourne. In humid regions, the location where flow begins in the smallest tributary streams moves upstream in response to precipitation and downstream in its absence or when active summer vegetation diverts water for evapotrans
The Cantabrian Mountains or Cantabrian Range are one of the main systems of mountain ranges in Spain. They stretch for over 300 km across northern Spain, from the western limit of the Pyrenees to the Galician Massif in Galicia, along the coast of the Cantabrian Sea, their easternmost end meets the Sistema Ibérico. These mountains are a distinct physiographic province of the larger Alpine System physiographic division; the Cantabrian Mountains offer a wide range of trails for hiking, as well as many challenging climbing routes. Skiing is possible in the ski resorts of Alto Campoo, Valgrande-Pajares, Fuentes de Invierno, San isidro and Manzaneda; the Cantabrian Mountains stretch east-west, nearly parallel to the sea, as far as the pass of Leitariegos extending south between León and Galicia. The range's western boundary is marked by the valley of the river Minho, by the lower Sil, which flows into the Miño, by the Cabrera River, a small tributary of the Sil. Cantabrian mountains reach its south-western limit in Portugal.
As a whole, the Cantabrian Mountains are remarkable for their intricate ramifications, but everywhere, in the east, it is possible to distinguish two principal ranges, from which the lesser ridges and mountain masses radiate. One range, or series of ranges follows the outline of the coast. In some parts the coastal range rises sheer above the sea, everywhere has so abrupt a declivity that the streams which flow seaward are all short and swift; the descent from the southern range to the high plateaux of Castile is more gradual, several large rivers, notably the Ebro, rise here and flow to the south or west. The breadth of the Cantabrian chain, with all its ramifications, increases from about 60 mi. Many peaks are over 6000 ft high, but the greatest altitudes are attained in the central ridges on the borders of León, Asturias and Cantabria. Here are the highest peak Torre de Cerredo, Peña Vieja, Peña Prieta and Espigüete. A conspicuous feature of the chain, as of the adjacent tableland, is the number of its parameras, isolated plateaus shut in by lofty mountains or by precipitous walls of rock.
The Cantabrian Mountains make a sharp divide between "Green Spain" to the north, the dry central plateau. The north facing slopes receive heavy cyclonic rainfall from the Bay of Biscay, whereas the southern slopes are in rain shadow; the Cantabrian Range has three distinct sections from west to east: The Asturian Massif and its foothills. Geologically it is an eastern prolongation of the Galician Massif with Paleozoic folds, it is cut by deep east-west oriented canyons such as the Cares River valley.

Castile and León
Castile and León (UK:, US:. It was constituted in 1983, although it existed for the first time during the First Spanish Republic in the 19th century. León first appeared as a Kingdom in 910, whilst the Kingdom of Castile gained an independent identity in 1065 and was intermittently held in personal union with León before merging with it in 1230. Though the kings of Castile and León continued to take the title King of León as the superior title, to use a lion as part of their standard, power in fact became centralized in Castile, as exemplified by the Leonese language's replacement by Spanish; the Kingdom of León and the Kingdom of Castile kept different parliaments, different flags, different coin and different laws until the Modern Era, when Spain, like other European states, centralized governmental power in 1833. The autonomous community of Castile and León is the result of the union in 1983 of nine provinces: the three that, after the territorial division of 1833, were part of the Region of León and six attached to the Old Castile, except in the latter case the provinces of Santander and Logroño.
It is the largest autonomous community in Spain and the third largest region of the European Union, covering an area of 94,223 square kilometres with an official population of around 2.5 million. From the beginning of the federalist debate in Spain in the 19th century during the First Spanish Republic there were projects of autonomy for a Castile and León region, as the project of Castilian Mancomunity, Bases de Segovia, Castilian Provincial League or Castilian Federal Pact, but including current Cantabria and La Rioja. Same project that continued to exist during the Second Spanish Republic and, carried out after the Constitution of 1978, but without Cantabria and La Rioja that, although it was considered to include them formed uniprovincial autonomies, its Statute of Autonomy declares in its preamble: The Autonomous Community of Castile and León arises from the modern union of the historical territories that composed and gave name to the old crowns of León and Castile. Eleven hundred years ago, the Kingdom of León was constituted, from which that of Castile and Galicia were dislodged as kingdoms throughout the 9th century, and, in 1143, that of Portugal.
During these two centuries the monarchs who held the government of these lands attained the dignity of emperors, as attested by the terms of Alfonso VI and Alfonso VII. In Castile and León, more than 60% of all of Spain's heritage sites are found. All of which translate into: 8 World Heritage sites 1800 classified cultural heritage assets, 112 historic sites, 400 museums, more than 500 castles, of which 16 are considered of high historical value, 12 cathedrals, 1 concathedral, the largest concentration of Romanesque art in the world. With 8 World Heritage sites, Castile and León is the region of the world with more cultural assets distinguished by the highest protection figure granted by UNESCO, ahead of the Italian regions of Tuscany and Lombardy, both with 6 sites; the Montes de Valsaín mountains and the Béjar and Francia mountain ranges, in the Sistema Central, the valleys of Laciana, Omaña y Luna and the Picos de Europa and Los Ancares, in the Cantabrian Mountains, the Iberian Plateau, in the border area with Portugal, have been declared biosphere reserve by UNESCO, which recognizes the geopark of La Lora with this figure of protection.
In addition, Castile and León is related to two of the records of the Memory of the World Programme of UNESCO which are the Decreta of the Cortes of León of 1188, curia regia considered the birthplace of worldwide parliamentarism by the institution itself, the Treaty of Tordesillas. The Index of development of social services reflects that the community has one of the best social services in the country, positioning itself as the third autonomy that offers the best benefits to its citizens, after the Basque Country and Navarre, its education, according to the Programme for International Student Assessment report of 2015, leads the scores in reading and sciences with a score comparable to that of the ten best countries in the study.23 April is designated Castile and León Day, commemorating the defeat of the comuneros at the Battle of Villalar during the Revolt of the Comuneros, in 1521. The Statute of Autonomy of Castile and León, reformed for the last time in 2007, establishes in the sixth article of its preliminary title the symbols of the community's exclusive identity.
These are: the coat of the flag, the banner and the anthem. Its legal protection is the same as that corresponding to the symbols of the State -whose outrages are classified as crime in article 543 of the Penal Code-. In the articulated statuary, the coat of arms is defined as follows: The coat of arms of Castile and León is a stamped shield by open royal crown, barracked in cross; the first and fourth quartering: in the field of gules, a merloned golden castle of three merlons, drafted of sable and rinse of azure. The second and third quartering: in a silver field, a rampant lion of purple, lingued and armed with gules, crowned with gold; the flag is described as follows: The flag of Castile and León is quartered and contains the symbols of Castile and León, as described in the previous section. The flag will fly in all the centres and official acts of the Community, to the right of the Spanish flag. Following the same wording, the banner is constituted by the shield quartered on a traditional crimson background.
The Statute expresses: "The anthem and the other sym
