A stream is a body of water with surface water flowing within the bed and banks of a channel. The stream encompasses surface and groundwater fluxes that respond to geological, geomorphological and biotic controls. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are called rivers. Streams are important as conduits in the water cycle, instruments in groundwater recharge, corridors for fish and wildlife migration; the biological habitat in the immediate vicinity of a stream is called a riparian zone. Given the status of the ongoing Holocene extinction, streams play an important corridor role in connecting fragmented habitats and thus in conserving biodiversity; the study of streams and waterways in general is known as surface hydrology and is a core element of environmental geography. Brook A stream smaller than a creek one, fed by a spring or seep, it is small and forded. A brook is characterised by its shallowness.
Creek In North America and New Zealand, a small to medium-sized natural stream. Sometimes navigable by motor craft and may be intermittent. In parts of Maryland, New England, the UK and India, a tidal inlet in a salt marsh or mangrove swamp, or between enclosed and drained former salt marshes or swamps. In these cases, the stream is the tidal stream, the course of the seawater through the creek channel at low and high tide. River A large natural stream, which may be a waterway. Runnel the linear channel between the parallel ridges or bars on a shoreline beach or river floodplain, or between a bar and the shore. Called a swale. Tributary A contributory stream, or a stream which does not reach a static body of water such as a lake or ocean, but joins another river. Sometimes called a branch or fork. There are a number of regional names for a stream. Allt is used in Highland Scotland. Beck is used in Lincolnshire to Cumbria in areas which were once occupied by the Danes and Norwegians. Bourne or winterbourne is used in the chalk downland of southern England.
Brook. Burn is used in North East England. Gill or ghyll is seen in Surrey influenced by Old Norse; the variant "ghyll" is used in the Lake District and appears to have been an invention of William Wordsworth. Nant is used in Wales. Rivulet is a term encountered in Victorian era publications. Stream Syke is used in lowland Cumbria for a seasonal stream. Branch is used to name streams in Virginia. Creek is common throughout the United States, as well as Australia. Falls is used to name streams in Maryland, for streams/rivers which have waterfalls on them if such falls have a small vertical drop. Little Gunpowder Falls and The Jones Falls are rivers named in this manner, unique to Maryland. Kill in New York, Pennsylvania and New Jersey comes from a Dutch language word meaning "riverbed" or "water channel", can be used for the UK meaning of'creek'. Run in Ohio, Michigan, New Jersey, Virginia, or West Virginia can be the name of a stream. Run in Florida is the name given to streams coming out of small natural springs.
River is used for larger springs like the Silver Rainbow River. Stream and brook are used in Midwestern states, Mid-Atlantic states, New England. Bar A shoal that develops in a stream as sediment is deposited as the current slows or is impeded by wave action at the confluence. Bifurcation A fork into two or more streams. Channel A depression created by constant erosion. Confluence The point at which the two streams merge. If the two tributaries are of equal size, the confluence may be called a fork. Drainage basin The area of land. A large drainage basin such as the Amazon River contains many smaller drainage basins. Floodplain Lands adjacent to the stream that are subject to flooding when a stream overflows its banks. Gaging station A site along the route of a stream or river, used for reference marking or water monitoring. Headwaters The part of a stream or river proximate to its source; the word is most used in the plural where there is no single point source. Knickpoint The point on a stream's profile where a sudden change in stream gradient occurs.
Mouth The point at which the stream discharges via an estuary or delta, into a static body of water such as a lake or ocean. Pool A segment where the water is deeper and slower moving. Rapids A turbulent, fast-flowing stretch of a stream or river. Riffle A segment where the flow is shallower and more turbulent. River A large natural stream, which may be a waterway. Run A somewhat smoothly flowing segment of the stream. Source The spring, or other point of origin of a stream. Spring The point at which a stream emerges from an underground course through unconsolidated sediments or through caves. A stream can with caves, flow aboveground for part of its course, underground for part of its course. Stream bed The bottom of a stream. Stream corridor Stream, its floodplains, the transitional upland fringe Streamflow The water moving through a stream channel. Thalweg The river's longitudinal section, or the line joining the deepest point in the channel at each stage from source to mouth. Waterfall or cascade The fall of water where the stream goes over a sudden drop called a knickpoint.
The stream expends kinetic energy in "trying" to eliminate the
The Terdoppio is a river of Piedmont and Lombardy. It starts from the Piedmontese Prealps in the area between Lake Orta and Lake Maggiore, crosses the province of Novara. Near Cerano, it splits into two different streams: the first joins the Ticino River, while the second flows through the Lomellina until it merges with the Po River; the Terdoppio is 86 kilometres long, with an average discharge of 3.7 cubic metres per second and a drainage basin of about 515 square kilometres
Mottarone is a mountain in the Western Alps of north-western Italy, with an elevation of 1,492 m. The peak is in the communal territory between the Lake Orta and Lake Maggiore; the source of the Agogna river is located in the mountain. Mottarone area is known for the production of cheese, the most renowned of, the Toma del Mottarone. According to the SOIUSA the mountain can be classified in the following way: main part = Western Alps major sector = North Western Alps section = Pennine Alps subsection = Southern Valsesia Alps supergroup = Alpi Cusiane group = Massiccio del Mottarone code = I/B-9. IV-B.4 The peak of Mottarone can be reached by a 20-minute ride on a cableway from Carciano, a frazione of Stresa. This was built to replace a rack and pinion railroad from Stresa in 1963, it overlooks the city of Verbania on the Lake Maggiore. It is possible reach the peak of Mottarone by car. There are two roads: the first comes up from Armeno, west of the Mottarone summit near Lake Orta. A ski resort with 21 km of downhill skiing slopes is located on Mottarone.
Skiing on Mottarone has a long tradition. Sci Club Mottarone was founded in 1909. In January 1935 the first giant slalom in the history of ski racing took place on the Mottarone. In 1940 the first ski lift opened called, Slittone. After World War II, the ski resort developed. Today there are something for every kind of skier. There are five ski lifts: Selva Spessa 2, La Rossa and Baita Omegna. In addition, there are two moving carpet lifts for the beginners. Another lift, called Alpe Corti, was closed after 2011 at the end of its "technical life", in accordance with Italian law which allows certain lifts to be used only 30 years. Mottarone online website
Piedmontese is a Romance language spoken by some 700,000 people in Piedmont, northwestern region of Italy. It is geographically and linguistically included in the Gallo-Italic languages group of Northern Italy, it is part of the wider western group of Romance languages, which includes French and Catalan. It is spoken in Piedmont and Lombardy. Many European and North American linguists acknowledge Piedmontese as an independent language, though in Italy it is still considered a dialect. Today it has a certain official status recognized by the Piedmont regional government, but not by the national government. Piedmontese was the first language of emigrants who, in the period from 1850 to 1950, left Piedmont for countries such as France, the United States and Uruguay; the first documents in the Piedmontese language were written in the 12th century, the sermones subalpini, when it was close to Occitan. Literary Piedmontese developed in the 17th and 18th centuries, but it did not gain literary esteem comparable to that of French or Italian, other languages used in Piedmont.
Literature in Piedmontese has never ceased to be produced: it includes poetry, theatre pieces and scientific work. In 2004, Piedmontese was recognised as Piedmont's regional language by the regional parliament, although the Italian government has not yet recognised it as such. In theory it is now supposed to be taught to children in school, but this is happening only to a limited extent; the last decade has seen the publication of learning materials for schoolchildren, as well as general-public magazines. Courses for people outside the education system have been developed. In spite of these advances, the current state of Piedmontese is quite grave, as over the last 150 years the number of people with a written active knowledge of the language has shrunk to about 2% of native speakers, according to a recent survey. On the other hand, the same survey showed Piedmontese is still spoken by over half the population, alongside Italian. Authoritative sources confirm this result, putting the figure between 2 million (Assimil, IRES Piemonte and 3 million speakers out of a population of 4.2 million people.
Efforts to make it one of the official languages of the Turin 2006 Winter Olympics were unsuccessful. Piedmontese is written with a modified Latin alphabet; the letters, along with their IPA equivalent, are shown in the table below. Certain digraphs are used to represent specific sounds as shown below. All other combinations of letters are pronounced as written. Grave accent marks stress and breaks diphthongs, so ua and uà are /wa/, but ùa is pronounced separately, /ˈya/; some of the characteristics of the Piedmontese language are: The presence of clitic so-called verbal pronouns for subjects, which give a Piedmontese verbal complex the following form: + verbal pronoun + verb, as in i von'I go'. Verbal pronouns are absent only in the imperative form; the bound form of verbal pronouns, which can be connected to dative and locative particles. The interrogative form, which adds an enclitic interrogative particle at the end of the verbal form The absence of ordinal numerals higher than'sixth', so that'seventh' is col che a fà set'the one which makes seven'.
The existence of three affirmative interjections: si, sè. The absence of the voiceless postalveolar fricative /ʃ/, for which an alveolar S sound is substituted; the existence of an S-C combination pronounced. The existence of a velar nasal, which precedes a vowel, as in lun-a'moon'; the existence of the third Piedmontese vowel Ë, short. The absence of the phonological contrast that exists in Italian between short and long consonants, for example, Italian fata'fairy' and fatta'done'; the existence of a prosthetic Ë sound when consonantal clusters arise that are not permitted by the phonological system. So'seven stars' is pronounced set ëstèile. Piedmontese has a number of varieties. Variation includes not only departures from the literary grammar, but a wide variety in dictionary entries, as different regions maintain words of Frankish or Lombard origin, as well as differences in native Romance terminology. Words imported from various languages are present, while more recent imports tend to come from France and from Italian.
A variety of Piedmontese was Judeo-Piedmontese, a dialect spoken by the Piedmontese Jews until the Second World War. Lexical comparison with other Romance languages and English: Zallio, A. G..

Italy the Italian Republic, is a country in Southern Europe. Located in the middle of the Mediterranean Sea, Italy shares open land borders with France, Austria and the enclaved microstates San Marino and Vatican City. Italy covers an area of 301,340 km2 and has a temperate seasonal and Mediterranean climate. With around 61 million inhabitants, it is the fourth-most populous EU member state and the most populous country in Southern Europe. Due to its central geographic location in Southern Europe and the Mediterranean, Italy has been home to a myriad of peoples and cultures. In addition to the various ancient peoples dispersed throughout modern-day Italy, the most famous of which being the Indo-European Italics who gave the peninsula its name, beginning from the classical era and Carthaginians founded colonies in insular Italy and Genoa, Greeks established settlements in the so-called Magna Graecia, while Etruscans and Celts inhabited central and northern Italy respectively; the Italic tribe known as the Latins formed the Roman Kingdom in the 8th century BC, which became a republic with a government of the Senate and the People.
The Roman Republic conquered and assimilated its neighbours on the peninsula, in some cases through the establishment of federations, the Republic expanded and conquered parts of Europe, North Africa and the Middle East. By the first century BC, the Roman Empire emerged as the dominant power in the Mediterranean Basin and became the leading cultural and religious centre of Western civilisation, inaugurating the Pax Romana, a period of more than 200 years during which Italy's technology, economy and literature flourished. Italy remained the metropole of the Roman Empire; the legacy of the Roman Empire endured its fall and can be observed in the global distribution of culture, governments and the Latin script. During the Early Middle Ages, Italy endured sociopolitical collapse and barbarian invasions, but by the 11th century, numerous rival city-states and maritime republics in the northern and central regions of Italy, rose to great prosperity through shipping and banking, laying the groundwork for modern capitalism.
These independent statelets served as Europe's main trading hubs with Asia and the Near East enjoying a greater degree of democracy than the larger feudal monarchies that were consolidating throughout Europe. The Renaissance began in Italy and spread to the rest of Europe, bringing a renewed interest in humanism, science and art. Italian culture flourished, producing famous scholars and polymaths such as Michelangelo, Leonardo da Vinci, Raphael and Machiavelli. During the Middle Ages, Italian explorers such as Marco Polo, Christopher Columbus, Amerigo Vespucci, John Cabot and Giovanni da Verrazzano discovered new routes to the Far East and the New World, helping to usher in the European Age of Discovery. Italy's commercial and political power waned with the opening of trade routes that bypassed the Mediterranean. Centuries of infighting between the Italian city-states, such as the Italian Wars of the 15th and 16th centuries, left the region fragmented, it was subsequently conquered and further divided by European powers such as France and Austria.
By the mid-19th century, rising Italian nationalism and calls for independence from foreign control led to a period of revolutionary political upheaval. After centuries of foreign domination and political division, Italy was entirely unified in 1871, establishing the Kingdom of Italy as a great power. From the late 19th century to the early 20th century, Italy industrialised, namely in the north, acquired a colonial empire, while the south remained impoverished and excluded from industrialisation, fuelling a large and influential diaspora. Despite being one of the main victors in World War I, Italy entered a period of economic crisis and social turmoil, leading to the rise of a fascist dictatorship in 1922. Participation in World War II on the Axis side ended in military defeat, economic destruction and the Italian Civil War. Following the liberation of Italy and the rise of the resistance, the country abolished the monarchy, reinstated democracy, enjoyed a prolonged economic boom and, despite periods of sociopolitical turmoil became a developed country.
Today, Italy is considered to be one of the world's most culturally and economically advanced countries, with the sixth-largest worldwide national wealth. Its advanced economy ranks eighth-largest in the world and third in the Eurozone by nominal GDP. Italy owns the third-largest central bank gold reserve, it has a high level of human development, it stands among the top countries for life expectancy. The country plays a prominent role in regional and global economic, military and diplomatic affairs. Italy is a founding and leading member of the European Union and a member of numerous international institutions, including the UN, NATO, the OECD, the OSCE, the WTO, the G7, the G20, the Union for the Mediterranean, the Council of Europe, Uniting for Consensus, the Schengen Area and many more; as a reflection
Geographic coordinate system
A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position. A common choice of coordinates is latitude and elevation. To specify a location on a plane requires a map projection; the invention of a geographic coordinate system is credited to Eratosthenes of Cyrene, who composed his now-lost Geography at the Library of Alexandria in the 3rd century BC. A century Hipparchus of Nicaea improved on this system by determining latitude from stellar measurements rather than solar altitude and determining longitude by timings of lunar eclipses, rather than dead reckoning. In the 1st or 2nd century, Marinus of Tyre compiled an extensive gazetteer and mathematically-plotted world map using coordinates measured east from a prime meridian at the westernmost known land, designated the Fortunate Isles, off the coast of western Africa around the Canary or Cape Verde Islands, measured north or south of the island of Rhodes off Asia Minor.
Ptolemy credited him with the full adoption of longitude and latitude, rather than measuring latitude in terms of the length of the midsummer day. Ptolemy's 2nd-century Geography used the same prime meridian but measured latitude from the Equator instead. After their work was translated into Arabic in the 9th century, Al-Khwārizmī's Book of the Description of the Earth corrected Marinus' and Ptolemy's errors regarding the length of the Mediterranean Sea, causing medieval Arabic cartography to use a prime meridian around 10° east of Ptolemy's line. Mathematical cartography resumed in Europe following Maximus Planudes' recovery of Ptolemy's text a little before 1300. In 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, England as the zero-reference line; the Dominican Republic voted against the motion, while Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911.
In order to be unambiguous about the direction of "vertical" and the "horizontal" surface above which they are measuring, map-makers choose a reference ellipsoid with a given origin and orientation that best fits their need for the area they are mapping. They choose the most appropriate mapping of the spherical coordinate system onto that ellipsoid, called a terrestrial reference system or geodetic datum. Datums may be global, meaning that they represent the whole Earth, or they may be local, meaning that they represent an ellipsoid best-fit to only a portion of the Earth. Points on the Earth's surface move relative to each other due to continental plate motion and diurnal Earth tidal movement caused by the Moon and the Sun; this daily movement can be as much as a metre. Continental movement can be up to 10 m in a century. A weather system high-pressure area can cause a sinking of 5 mm. Scandinavia is rising by 1 cm a year as a result of the melting of the ice sheets of the last ice age, but neighbouring Scotland is rising by only 0.2 cm.
These changes are insignificant if a local datum is used, but are statistically significant if a global datum is used. Examples of global datums include World Geodetic System, the default datum used for the Global Positioning System, the International Terrestrial Reference Frame, used for estimating continental drift and crustal deformation; the distance to Earth's center can be used both for deep positions and for positions in space. Local datums chosen by a national cartographical organisation include the North American Datum, the European ED50, the British OSGB36. Given a location, the datum provides the latitude ϕ and longitude λ. In the United Kingdom there are three common latitude and height systems in use. WGS 84 differs at Greenwich from the one used on published maps OSGB36 by 112 m; the military system ED50, used by NATO, differs from about 120 m to 180 m. The latitude and longitude on a map made against a local datum may not be the same as one obtained from a GPS receiver. Coordinates from the mapping system can sometimes be changed into another datum using a simple translation.
For example, to convert from ETRF89 to the Irish Grid add 49 metres to the east, subtract 23.4 metres from the north. More one datum is changed into any other datum using a process called Helmert transformations; this involves converting the spherical coordinates into Cartesian coordinates and applying a seven parameter transformation, converting back. In popular GIS software, data projected in latitude/longitude is represented as a Geographic Coordinate System. For example, data in latitude/longitude if the datum is the North American Datum of 1983 is denoted by'GCS North American 1983'; the "latitude" of a point on Earth's surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the Equator and to each other; the North Pole is 90° N. The 0° parallel of latitude is designated the Equator, the fun
A nature reserve is a protected area of importance for flora, fauna or features of geological or other special interest, reserved and managed for conservation and to provide special opportunities for study or research. Nature reserves may be designated by government institutions in some countries, or by private landowners, such as charities and research institutions, regardless of nationality. Nature reserves fall into different IUCN categories depending on the level of protection afforded by local laws, it is more protected than a nature park. Cultural practices that equate to the establishment and maintenance of reserved areas for animals date back to antiquity, with King Devanampiya Tissa of Anuradhapura establishing one of the world's earliest wildlife sanctuaries in the 3rd century BC. Early reservations had a religious underpinning, such as the'evil forest' areas of West Africa which were forbidden to humans, who were threatened with spiritual attack if they went there. Sacred areas taboo from human entry to fishing and hunting are known by many ancient cultures worldwide.
The world's first modern nature reserve was established in 1821 by the naturalist and explorer Charles Waterton around his estate in Walton Hall, West Yorkshire. He spent £9000 on the construction of a 3 mile long, 9 ft tall wall to enclose his park from poachers, he tried to encourage birdlife by hollowing out trunks for owls to nest in. He invented artificial nest boxes to house starlings and sand martins and unsuccessfully attempted to introduce little owls from Italy. Waterton allowed local people access to his reserve and was described by David Attenborough as “one of the first people anywhere to recognise not only that the natural world was of great importance but that it needed protection as humanity made more and more demands on it”. Drachenfels was protected as the first state-designated nature reserve in modern-day Germany; the first major nature reserve was Yellowstone National Park in Wyoming, United States, followed by the Royal National Park near Sydney and the Barguzin Nature Reserve of Imperial Russia, the first of zapovedniks set up by a federal government for the scientific study of nature.
In Australia, a nature reserve is the title of a type of protected area used in the jurisdictions of the Australian Capital Territory, New South Wales and Western Australia. The term “nature reserve” is defined in the relevant statutes used in those states and territories rather than by a single national statute; as of 2016, 1767 out of a total of 11044 protected areas listed within the Australian National Reserve System used the term “nature reserve" in their names. In Brazil, nature reserves are classified as ecological stations estações ecológicas) or biological reserves by the National System of Conservation Units, their main objectives are preserving fauna and flora and other natural attributes, excluding direct human interference. Visits are allowed only with permission, only for educational or scientific purposes. Changes to the ecosystems in both types of reserve are allowed to restore and preserve the natural balance, biological diversity and natural ecological processes. Ecological stations are allowed to change the environment within defined limits for the purpose of scientific research.
A wildlife reserve in Brazil is protected, hunting is not allowed, but products and by-products from research may be sold. There are 30 nature reserves in Egypt; those nature reserves were built according to the laws no. 102/1983 and 4/1994 for protection of the Egyptian nature reserve. Egypt announced a plan from to build 40 nature reserves from 1997 to 2017, to help protect the natural resources and the culture and history of those areas; the largest nature reserve in Egypt is Gebel Elba in the southeast, on the Red Sea coast. Denmark has three national parks and several nature reserves, some of them inside the national park areas; the largest single reserve is Hanstholm Nature Reserve, which covers 40 km2 and is part of Thy National Park. In Sweden, there are 29 national parks; the first of them was established in 1909. In fact, Sweden was the first European country. There are 4,000 nature reserves in Sweden, they comprise about 85% of the surface, protected by the Swedish Environmental Code. In Estonia, there are 5 national parks, more than 100 nature reserves, around 130 landscape protection areas.
The largest nature reserve in Estonia is Alam-Pedja Nature Reserve, which covers 342 km2. As of 2017, France counts 10 national parks, around 8 marine parks. In 1995 Germany had 5,314 nature reserves covering 6,845 km2, the largest total areas being in Bavaria with 1,416 km2 and Lower Saxony with 1,275 km2. In Hungary, there are 10 National Parks, more than 15 nature reserves and more than 250 protected areas. Hortobágy National Park is the largest continuous natural grassland in Europe and the oldest national park in Hungary, it is situated on the plain of the Alföld. It was established in 1972. There are alkaline grasslands interrupted by marshes, they have a sizable importance. One of the most spectacular sights of the park is the autumn mi
