Buenos Aires
–
Buenos Aires is the capital and most populous city of Argentina. The city is located on the shore of the estuary of the Río de la Plata. The city of Buenos Aires is neither part of Buenos Aires Province nor the Provinces capital, rather, in 1880, after decades of political infighting, Buenos Aires was federalized and removed from Buenos Aires Province. The city limits were enlarged to include the towns of Belgrano and Flores, the 1994 constitutional amendment granted the city autonomy, hence its formal name, Ciudad Autónoma de Buenos Aires. Its citizens first elected a chief of government in 1996, previously, Buenos Aires is considered an alpha city by the study GaWC5. Buenos Aires quality of life was ranked 81st in the world and one of the best in Latin America in 2012 and it is the most visited city in South America, and the second-most visited city of Latin America. Buenos Aires is a top tourist destination, and is known for its preserved Spanish/European-style architecture, Buenos Aires held the 1st Pan American Games in 1951 as well as hosting two venues in the 1978 FIFA World Cup. Buenos Aires will host the 2018 Summer Youth Olympics and the 2018 G20 summit, Buenos Aires is a multicultural city, being home to multiple ethnic and religious groups. Several languages are spoken in the city in addition to Spanish, contributing to its culture, the hill was known to them as Buen Ayre, as it was free of the foul smell prevalent in the old city, which is adjacent to swampland. During the siege of Cagliari, the Aragonese built a sanctuary to the Virgin Mary on top of the hill, in 1335, King Alfonso the Gentle donated the church to the Mercedarians, who built an abbey that stands to this day. In the years after that, a story circulated, claiming that a statue of the Virgin Mary was retrieved from the sea after it miraculously helped to calm a storm in the Mediterranean Sea, the statue was placed in the abbey. Spanish sailors, especially Andalusians, venerated this image and frequently invoked the Fair Winds to aid them in their navigation, a sanctuary to the Virgin of Buen Ayre would be later erected in Seville. Pedro de Mendoza called the city Holy Mary of the Fair Winds, mendoza’s settlement soon came under attack by indigenous people, and was abandoned in 1541. For many years, the name was attributed to a Sancho del Campo, a second settlement was established in 1580 by Juan de Garay, who sailed down the Paraná River from Asunción. Garay preserved the name chosen by Mendoza, calling the city Ciudad de la Santísima Trinidad y Puerto de Santa María del Buen Aire. The short form Buenos Aires became the common usage during the 17th century, the usual abbreviation for Buenos Aires in Spanish is Bs. As. It is common as well to refer to it as B. A. or BA /ˌbiːˈeɪ/ bee-AY), while BA is used more by expats residing in the city, the locals more often use the abbreviation Baires, in one word. Seaman Juan Díaz de Solís, navigating in the name of Spain, was the first European to reach the Río de la Plata in 1516 and his expedition was cut short when he was killed during an attack by the native Charrúa tribe in what is now Uruguay

Argentina
–
Argentina, officially the Argentine Republic, is a federal republic in the southern half of South America. With a mainland area of 2,780,400 km2, Argentina is the eighth-largest country in the world, the second largest in Latin America, and the largest Spanish-speaking one. The country is subdivided into provinces and one autonomous city, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system, Argentina claims sovereignty over part of Antarctica, the Falkland Islands, and South Georgia and the South Sandwich Islands. The earliest recorded presence in the area of modern-day Argentina dates back to the Paleolithic period. The country has its roots in Spanish colonization of the region during the 16th century, Argentina rose as the successor state of the Viceroyalty of the Río de la Plata, a Spanish overseas viceroyalty founded in 1776. The country thereafter enjoyed relative peace and stability, with waves of European immigration radically reshaping its cultural. The almost-unparalleled increase in prosperity led to Argentina becoming the seventh wealthiest developed nation in the world by the early 20th century, Argentina retains its historic status as a middle power in international affairs, and is a prominent regional power in the Southern Cone and Latin America. Argentina has the second largest economy in South America, the third-largest in Latin America and is a member of the G-15 and it is the country with the second highest Human Development Index in Latin America with a rating of very high. Because of its stability, market size and growing high-tech sector, the description of the country by the word Argentina has to be found on a Venice map in 1536. In English the name Argentina probably comes from the Spanish language, however the naming itself is not Spanish, Argentina means in Italian of silver, silver coloured, probably borrowed from the Old French adjective argentine of silver > silver coloured already mentioned in the 12th century. The French word argentine is the form of argentin and derives of argent silver with the suffix -in. The Italian naming Argentina for the country implies Argentina Terra land of silver or Argentina costa coast of silver, in Italian, the adjective or the proper noun is often used in an autonomous way as a substantive and replaces it and it is said lArgentina. The name Argentina was probably first given by the Venitian and Genoese navigators, in Spanish and Portuguese, the words for silver are respectively plata and prata and of silver is said plateado and prateado. Argentina was first associated with the silver mountains legend, widespread among the first European explorers of the La Plata Basin. The first written use of the name in Spanish can be traced to La Argentina, a 1602 poem by Martín del Barco Centenera describing the region, the 1826 constitution included the first use of the name Argentine Republic in legal documents. The name Argentine Confederation was also used and was formalized in the Argentine Constitution of 1853. In 1860 a presidential decree settled the name as Argentine Republic

Ramsar Convention
–
The Ramsar Convention is an international treaty for the conservation and sustainable use of wetlands. It is also known as the Convention on Wetlands and it is named after the city of Ramsar in Iran, where the Convention was signed in 1971. The most recent COP12 was held in Punta del Este, Uruguay, cOP13 will take place in Dubai, United Arab Emirates, in 2018. The List of Wetlands of International Importance included 2,231 Ramsar Sites in March 2016 covering over 2.1 million square kilometres. The country with the highest number of Sites is the United Kingdom with 170, the Ramsar Sites Information Service is a searchable database which provides information on each Ramsar Site. As of 2016 there are 18 Transboundary Ramsar Sites, as of 2016 there are 15 Ramsar Regional Initiatives covering regions of the Mediterranean, Asia, Africa and South America. The Ramsar Convention works closely with six other known as International Organization Partners. The IOPs also participate regularly as observers in all meetings of the Conference of the Parties and as members of the Scientific. Conference of the Parties Conference of the Parties is the Conventions governing body consisting of all governments that have ratified the treaty and this ultimate authority reviews progress under the Convention, identifies new priorities, and sets work plans for members. The COP can also make amendments to the Convention, create expert advisory bodies, review progress reports by member nations, and collaborate with other international organizations and agreements. The Standing Committee The Standing Committee is the executive body which represents the COP between its triennial meetings, within the framework of the decisions made by the COP. The Contracting Parties that are members of the Standing Committee are elected by each meeting of the COP to serve for the three years until the next one, the Secretariat The Secretariat carries out the day-to-day coordination of the Convention’s activities. It is based at the headquarters of the International Union for the Conservation of Nature in Gland, Switzerland, the 2nd of February each year is World Wetlands Day, marking the date of the adoption of the Convention on Wetlands on 2 February 1971. Established to raise awareness about the value of wetlands for humanity, in 2015 World Wetlands Day was celebrated in 59 countries

Tigre, Buenos Aires
–
Tigre is a town in the Buenos Aires Province, Argentina, situated in the north of Greater Buenos Aires,28 km north of Buenos Aires city. Tigre lies on the Paraná Delta and is an important tourist and weekend attraction, easily reached by bus and train services and it is the principal town of the Tigre Partido. The town sits on an island created by small streams and rivers and was founded in 1820, after floods had destroyed other settlements in the area. The areas name derives from the “tigres” or jaguars that were hunted there, on occasions, in its early years. The area was first settled by Europeans who came to farm the land, Tigre is still an important timber processing port. The “Puerto de Frutos” is now a crafts fair located in the old fruit market by the riverside, the Naval Museum is also nearby. Antiques shops, riverside restaurants and pubs, the casino and Parque de la Costa, Tigre is also the starting point for a visit to the Paraná Delta. For locals and tourists alike, vintage mahogany commuter launches and motorboats are the way to travel through its web of inter-connecting rivers. Tigre has, in recent years, seen an influx of people relocating to the city from other parts of Greater Buenos Aires, in recent years it has seen a rise in upmarket tourism, spawning new spa developments and clientele such as the pop star, Madonna. The town of Tigre is served by two lines, the Mitre Line and the scenic Tren de la Costa, both terminate at walking distance from all venues. Mitre Line Retiro – Tigre The Mitre Line departs from Buenos Aires Retiro Station to Tigre Station every 10 –30 minutes. The Tren de la Costa has two types of tickets, a direct Maipú – Delta service and another allows the visitor off at various stations without paying any extra. The Tren de la Costa runs every twenty minutes daily, commuter passenger boats, water taxis and ferries provide public transport within the Tigre Delta.

Spanish language
–
Spanish —also called Castilian —is a Romance language that originated in the Castile region of Spain, with hundreds of millions of native speakers around the world. It is usually considered the worlds second-most spoken native language after Mandarin Chinese and it is one of the few languages to use inverted question and exclamation marks. Spanish is a part of the Ibero-Romance group of languages, which evolved from several dialects of Vulgar Latin in Iberia after the collapse of the Western Roman Empire in the 5th century. Beginning in the early 16th century, Spanish was taken to the colonies of the Spanish Empire, most notably to the Americas, as well as territories in Africa, Oceania, around 75% of modern Spanish is derived from Latin. Greek has also contributed substantially to Spanish vocabulary, especially through Latin, Spanish vocabulary has been in contact from an early date with Arabic, having developed during the Al-Andalus era in the Iberian Peninsula. With around 8% of its vocabulary being Arabic in origin, this language is the second most important influence after Latin and it has also been influenced by Basque as well as by neighboring Ibero-Romance languages. It also adopted words from languages such as Gothic language from the Visigoths in which many Spanish names and surnames have a Visigothic origin. Spanish is one of the six languages of the United Nations. It is the language in the world by the number of people who speak it as a mother tongue, after Mandarin Chinese. It is estimated more than 437 million people speak Spanish as a native language. Spanish is the official or national language in Spain, Equatorial Guinea, speakers in the Americas total some 418 million. In the European Union, Spanish is the tongue of 8% of the population. Spanish is the most popular second language learned in the United States, in 2011 it was estimated by the American Community Survey that of the 55 million Hispanic United States residents who are five years of age and over,38 million speak Spanish at home. The Spanish Constitution of 1978 uses the term castellano to define the language of the whole Spanish State in contrast to las demás lenguas españolas. Article III reads as follows, El castellano es la lengua española oficial del Estado, las demás lenguas españolas serán también oficiales en las respectivas Comunidades Autónomas. Castilian is the official Spanish language of the State, the other Spanish languages as well shall be official in their respective Autonomous Communities. The Spanish Royal Academy, on the hand, currently uses the term español in its publications. Two etymologies for español have been suggested, the Spanish Royal Academy Dictionary derives the term from the Provençal word espaignol, and that in turn from the Medieval Latin word Hispaniolus, from—or pertaining to—Hispania

River delta
–
A river delta is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, River deltas are ecologically important as they provide coastline defense, are home to many species, and can impact drinking water supply. The tidal currents also cannot be too strong, as sediment would wash out into the body faster than the river deposits it. Of course, the river must carry enough sediment to layer into deltas over time, the rivers velocity decreases rapidly, causing it to deposit the majority, if not all, of its load. This alluvium builds up to form the river delta, when the flow enters the standing water, it is no longer confined to its channel and expands in width. This flow expansion results in a decrease in the flow velocity, as a result, sediment drops out of the flow and deposits. Over time, this single channel builds a deltaic lobe, pushing its mouth into the standing water, as the deltaic lobe advances, the gradient of the river channel becomes lower because the river channel is longer but has the same change in elevation. As the slope of the channel decreases, it becomes unstable for two reasons. First, gravity makes the flow in the most direct course down slope. If the river breaches its natural levees, it out onto a new course with a shorter route to the ocean. Second, as its slope gets lower, the amount of stress on the bed decreases, which results in deposition of sediment within the channel. This makes it easier for the river to breach its levees, often when the channel does this, some of its flow remains in the abandoned channel. When these channel-switching events occur, a mature delta develops a distributary network, another way these distributary networks form is from deposition of mouth bars. When this mid-channel bar is deposited at the mouth of a river and this results in additional deposition on the upstream end of the mouth-bar, which splits the river into two distributary channels. A good example of the result of this process is the Wax Lake Delta, in both of these cases, depositional processes force redistribution of deposition from areas of high deposition to areas of low deposition. This results in the smoothing of the shape of the delta as the channels move across its surface. Because the sediment is laid down in fashion, the shape of these deltas approximates a fan. The more often the flow changes course, the shape develops as closer to an ideal fan, the Mississippi and Ural River deltas, with their birds-feet, are examples of rivers that do not avulse often enough to form a symmetrical fan shape

Alluvium
–
Alluvium is loose, unconsolidated soil or sediments, which has been eroded, reshaped by water in some form, and redeposited in a non-marine setting. Alluvium is typically made up of a variety of materials, including fine particles of silt and clay and larger particles of sand, when this loose alluvial material is deposited or cemented into a lithological unit, or lithified, it is called an alluvial deposit. The term alluvium is not typically used in situations where the formation of the sediment can clearly be attributed to another process that is well described. This includes, lake sediments, river sediments, or glacially-derived sediments, sediments that are formed or deposited in a perennial stream or river are typically not referred to as alluvial. Most alluvium is very young, and is often referred to as cover because these sediments obscure the underlying bedrock. Most sedimentary material that fills a basin that is not lithified is typically lumped together as alluvial, alluvium of Pliocene age occurs, for example, in parts of Idaho. Alluvium of late Miocene age occurs, for example, in the valley of the San Joaquin River, alluvium can contain valuable ores such as gold and platinum and a wide variety of gemstones. Such a concentration of ores is termed a placer deposit
8.
Floodplain
–
In other words, a floodplain is an area near a river or a stream which floods when the water level reaches flood stage. Flood plains are made by a meander eroding sideways as it travels downstream, when a river breaks its banks and floods, it leaves behind layers of alluvium. These gradually build up to create the floor of the flood plain, floodplains generally contain unconsolidated sediments, often extending below the bed of the stream. These are accumulations of sand, gravel, loam, silt, and/or clay, and are often important aquifers, geologically ancient floodplains are often represented in the landscape by fluvial terraces. These are old floodplains that remain relatively high above the present floodplain and it is probable that any section of such an alluvial plain would show deposits of a similar character. The floodplain during its formation is marked by meandering or anastomotic streams, oxbow lakes and bayous, marshes or stagnant pools, and is occasionally completely covered with water. When the drainage system has ceased to act or is diverted for any reason. The floodplain differs, however, because it is not altogether flat and it has a gentle slope downstream, and often, for a distance, from the side towards the center. The floodplain is the place for a river to dissipate its energy. Meanders form over the floodplain to slow down the flow of water, in terms of flood management the upper part of the floodplain is crucial as this is where the flood water control starts. Artificial canalisation of the river here will have a impact on wider flooding. This is the basis of flood management. Floodplains can support particularly rich ecosystems, both in quantity and diversity, tugay forests form an ecosystem associated with floodplains, especially in Central Asia. They are a category of riparian zones or systems, a floodplain can contain 100 or even 1,000 times as many species as a river. Microscopic organisms thrive and larger species enter a rapid breeding cycle, opportunistic feeders move in to take advantage. The production of nutrients peaks and falls away quickly, however the surge of new growth endures for some time and this makes floodplains particularly valuable for agriculture. River flow rates are undergoing change following suit with climate change and this change is a threat to the riparian zones and other flood plain forests. These forests have over time synced their seedling deposits after the peaks in flow to best take advantage of the nutrient rich soil generated by peak flow

Provinces of Argentina
–
Argentina is subdivided into twenty-three provinces and one autonomous city, Ciudad Autónoma de Buenos Aires, which is the federal capital of the nation as decided by Congress. The provinces and the capital have their own constitutions, but exist under a federal system, during the War of Independence the main cities and their surrounding countrysides became provinces though the intervention of their cabildos. The Anarchy of the Year XX completed this process, shaping the original thirteen provinces, Jujuy seceded from Salta in 1834, and the thirteen provinces became fourteen. After seceding for a decade, Buenos Aires Province accepted the 1853 Constitution of Argentina in 1861, a law from 1862 designated as national territories those under federal control but outside the frontiers of the provinces. In 1884 they served as bases for the establishment of the governorates of Misiones, Formosa, Chaco, La Pampa, Neuquén, Río Negro, Chubut, Santa Cruz and Tierra del Fuego. The agreement about a dispute with Chile in 1900 created the National Territory of Los Andes, its lands were incorporated into Jujuy, Salta. La Pampa and Chaco became provinces in 1951, Misiones did so in 1953, and Formosa, Neuquén, Río Negro, Chubut and Santa Cruz, in 1955. The last national territory, Tierra del Fuego, became the Tierra del Fuego, Argentina is a federation of twenty-three provinces and one autonomous city, Buenos Aires. Provinces are divided for administration purposes into departments and municipalities, except for Buenos Aires Province, Buenos Aires City itself is divided into communes. Provinces hold all the power that they not to delegate to the federal government, they must be representative republics. Beyond this they are autonomous, they enact their own constitutions, freely organize their local governments. Since 1983 four provinces were intervened, namely Catamarca, Corrientes, Santiago del Estero, article 61 of the Constitution of the city of Buenos Aires states that Suffrage is free, equal, secret, universal, compulsory and not accumulative. The foreign residents enjoy this right, with the obligations, on equal terms with Argentine citizens registered in this district. Argentina is divided into seven geographical regions, many provinces having their territories across more than one.
