Caledon, Ontario
–
Caledon is a town in the Regional Municipality of Peel in the Greater Toronto Area of Ontario, Canada. In terms of use, Caledon is a developing urban area. It consists of an amalgamation of a number of areas, villages. Caledon is one of three municipalities of Peel Region, the town is located just northwest of the city of Brampton. At over 688 square km, Caledon is the largest city or town by area in the Greater Toronto Area, macleans magazine has named Caledon the safest town in Canada to live in for two years running. The Town of Caledon was established on January 1,1974 in conjunction with the creation of regional government, the County of Peel was created in 1805 following the purchase by the British Crown of the southern part of the Mississauga Tract on the shore of Lake Ontario. The lot and concession grid pattern of the New Survey was distinct from that of the Old Survey, with a different orientation of concessions and lot dimensions. The 200 acre lots of the New Survey were typically granted in square 100 acre parcels, surveyed in 1818-1819, the townships of Albion, Caledon and Chinguacousy were opened for settlement in 1820. Albion Township comprised eleven concessions laid out west to east, in Caledon and Chinguacousy townships, six concessions were laid out on either side of Hurontario Street, also known as Centre Road. As this centre baseline duplicated the numbering of the concessions, concessions in these two townships were further denoted by West of Hurontario Street or East of Hurontario Street, early settlements in the townships developed around water-powered mill sites on the Credit and Humber rivers, and at various crossroads. The arrival of the Toronto Grey & Bruce, Hamilton & Northwestern, development was also influenced by the areas major landforms, including the Peel Plain, the Niagara Escarpment and the Oak Ridges Moraine. Who came from the area around Caledon, County Tyrone in Northern Ireland, according to the 2011 Canadian Census, the population of Caledon is 59,460, a 4. 2% increase from 2006. The population density is 86.4 people per square km, the median age is 40.4 years old, basically on par with the national median at 40.6 years old.

River Wey
–
The River Wey is a tributary of the River Thames in south east England and one of two major tributaries in Surrey. It begins as two branches rising outside the county which join at Tilford between Guildford and Farnham, once combined the flow is eastwards then northwards via Godalming and Guildford to meet the Thames while in Surrey. Downstream the river forms the backdrop to Newark Priory and Brooklands, the name may be derived from the Old English word Éa meaning river. The Wey has a catchment area of 904 square kilometres, draining parts of Surrey, Hampshire. It joins the River Thames between Hamm Court and Whittets Ait facing a weirstream of Shepperton Lock and it is navigable from Godalming to its confluence as part of the Wey and Godalming Navigations, a trade-minded 17th century canal. The river morphology, biodiversity and flow are well studied, with places to take samples. The Wey North branch rises in Alton in Hampshire and runs eastwards through Upper Froyle and Bentley and this branch was originally the upper catchment of the Blackwater, this early river Wey captured waters from as far as Tilford. When this branch was blocked at Farnham, the flow spilt over into areas such as Elstead, the Blackwater remains as a much shorter river to the north of Farnham, with a wind gap between it and the Wey. The Wey South branch commences in two shorter rivers leading from separate sources, one is at Black Down near Haslemere and runs through Liphook, Bramshott, Passfield, Standford, Lindford and Frensham to Tilford. The other rises at Inval, below Gibbet Hill, Hindhead in the parish of Haslemere. This joins the Blackdown-source south branch west of Haslemere, other smaller tributaries of the south branch are Coopers Stream and the River Slea. From Godalming the river is intertwined with the Wey and Godalming Navigations which are manmade canals, the River Ock joins at Godalming, Cranleigh Waters and the River Tillingbourne at Shalford and the Hoe Stream at Woking. The 19.5 miles towpath of the section is open to pedestrians. During the seventeenth century the river was navigable to Guildford. The Basingstoke Canal and Wey and Arun Junction Canal were later connected to the river, the navigable sections are now owned by the National Trust. The river has long used as a source of power for mills. At one point there were 22 mills on the river, at various times they have been used for grinding grain, fulling wool, rolling oats, crushing cattle cake, leather dressing, paper production and gunpowder manufacture. Willey Mill was still in use in 1953, there has been a mill on the site of Guildford Town Mill since at least 1649

Hampshire
–
Hampshire is a county on the southern coast of England in the United Kingdom. The county town of Hampshire is Winchester, the capital city of England. The larger South Hampshire metropolitan area has a population of 1,547,000, Hampshire is notable for housing the birthplaces of the Royal Navy, British Army, and Royal Air Force. It is bordered by Dorset to the west, Wiltshire to the north-west, Berkshire to the north, Surrey to the north-east, the southern boundary is the coastline of the English Channel and the Solent, facing the Isle of Wight. At its greatest size in 1890, Hampshire was the fifth largest county in England and it now has an overall area of 3,700 square kilometres, and measures about 86 kilometres east–west and 76 kilometres north–south. Hampshires tourist attractions include many seaside resorts and two parks, the New Forest and the South Downs. Hampshire has a maritime history and two of Europes largest ports, Portsmouth and Southampton, lie on its coast. The county is famed as home of writers Jane Austen and Charles Dickens, Hampshire takes its name from the settlement that is now the city of Southampton. Southampton was known in Old English as Hamtun, roughly meaning village-town, the old name was recorded in the Domesday book as Hantescire, and it is from this spelling that the modern abbreviation Hants derives. From 1889 until 1959, the county was named the County of Southampton and has also been known as Southamptonshire. The region is believed to have continuously occupied since the end of the last Ice Age about 12,000 BCE. At this time Britain was still attached to the European continent and was covered with deciduous woodland. The first inhabitants came overland from Europe, these were anatomically and behaviourally modern humans, notable sites from this period include Bouldnor Cliff. Agriculture had arrived in southern Britain by 4000 BCE, and with it a neolithic culture, some deforestation took place at that time, although it was during the Bronze Age, beginning in 2200 BCE, that this became more widespread and systematic. Hampshire has few monuments to show from early periods, although nearby Stonehenge was built in several phases at some time between 3100 BCE and 2200 BCE. It is maintained that by this period the people of Britain predominantly spoke a Celtic language, hillforts largely declined in importance in the second half of the second century BCE, with many being abandoned. Julius Caesar invaded southeastern England briefly in 55 and again in 54 BCE, notable sites from this period include Hengistbury Head, which was a major port. There is a Museum of the Iron Age in Andover, the Romans invaded Britain again in 43 CE, and Hampshire was incorporated into the Roman province of Britannia very quickly

River
–
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, 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, creek, brook, rivulet, and rill. There are no official definitions for the term river as applied to geographic features. Many names for small rivers are specific to geographic location, examples are run in parts of the United States, burn in Scotland and northeast England. Sometimes a river is defined as being larger than a creek, but not always, Rivers are part of the hydrological cycle. Potamology is the study of rivers while limnology is the study of inland waters in general. Extraterrestrial rivers of liquid hydrocarbons have recently found on Titan. Channels may indicate past rivers on other planets, specifically outflow channels on Mars and rivers are theorised to exist on planets, a river begins at a source, follows a path called a course, and ends at a mouth or mouths. The water in a river is confined to a channel. 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, especially in areas where the floodplain of a river channel can become greatly developed by housing. Rivers can flow down mountains, through valleys or along plains, the term upriver refers to the direction towards the source of the river, i. e. against the direction of flow. Likewise, the term describes the direction towards the mouth of the river. The term left bank refers to the bank in the direction of flow. The river channel typically contains a stream of water, but some rivers flow as several interconnecting streams of water. Extensive braided rivers are now found in only a few regions worldwide and they also occur on peneplains and some of the larger river deltas. Anastamosing rivers are similar to braided rivers and are quite rare

Stream
–
A stream is a body of water with a current, confined within a bed and banks. Streams are important as conduits in the cycle, instruments in groundwater recharge. The biological habitat in the 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, 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, especially one that is fed by a spring or seep and it is usually small and easily forded. A brook is characterised by its shallowness and its bed being composed primarily of rocks, creek In North America, Australia 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, typically in a salt marsh or mangrove swamp, or between enclosed and drained former salt marshes or swamps. In these cases, the stream is the stream, the course of the seawater through the creek channel at low. 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. Tributary A contributory stream, or a stream which does not reach the sea, sometimes also called a branch or fork. There are a number of names for a stream. Allt is used in Highland Scotland, beck is used in Yorkshire, Lancashire, Dumfriesshire, Cumbria, Norfolk, and Lincolnshire. Bourne or winterbourne is used in the chalk downland of southern England, brook is used in the Midlands, Lancashire and Cheshire. Burn is used in Scotland and North East England, gill or ghyll is seen in the north of England and other areas influenced by Old Norse. Rivulet is an term encountered in Victorian era publications, stream is used in Southern England. Syke is used in lowland Scotland and Cumbria for a seasonal stream, branch is used to name streams in Maryland and Virginia. Falls is also used to name streams in Maryland, for streams/rivers which have waterfalls on them, little Gunpowder Falls and The Jones Falls are actually rivers named in this manner, unique to Maryland. Kill in New York, Pennsylvania, Delaware, and New Jersey comes from a Dutch language word meaning riverbed or water channel, run in Ohio, Maryland, Michigan, New Jersey, Pennsylvania, Virginia, or West Virginia can be the name of a stream
6.
Estuary
–
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a zone between river environments and maritime environments. They are subject both to marine influences—such as tides, waves, and the influx of saline water—and to riverine influences—such as flows of fresh water and sediment. The inflows of sea water and fresh water provide high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea began to rise about 10. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns, the banks of many estuaries are amongst the most heavily populated areas of the world, with about 60% of the worlds population living along estuaries and the coast. The word estuary is derived from the Latin word aestuarium meaning tidal inlet of the sea, there have been many definitions proposed to describe an estuary. However, this definition excludes a number of water bodies such as coastal lagoons. This broad definition also includes fjords, lagoons, river mouths, an estuary is a dynamic ecosystem having a connection to the open sea through which the sea water enters with the rhythm of the tides. The sea water entering the estuary is diluted by the water flowing from rivers. The pattern of dilution varies between different estuaries and depends on the volume of water, the tidal range. Drowned river valleys are known as coastal plain estuaries. In places where the sea level is rising relative to the land, sea water progressively penetrates into river valleys and this is the most common type of estuary in temperate climates. Well-studied estuaries include the Severn Estuary in the United Kingdom and the Ems Dollard along the Dutch-German border, the width-to-depth ratio of these estuaries is typically large, appearing wedge-shaped in the inner part and broadening and deepening seaward. Water depths rarely exceed 30 m, examples of this type of estuary in the U. S. are the Hudson River, Chesapeake Bay, and Delaware Bay along the Mid-Atlantic coast, and Galveston Bay and Tampa Bay along the Gulf Coast. They are relatively common in tropical and subtropical locations and these estuaries are semi-isolated from ocean waters by barrier beaches. Formation of barrier beaches partially encloses the estuary, with only narrow inlets allowing contact with the ocean waters, bar-built estuaries typically develop on gently sloping plains located along tectonically stable edges of continents and marginal sea coasts. They are extensive along the Atlantic and Gulf coasts of the U. S. in areas with active coastal deposition of sediments, barrier beaches form in shallow water and are generally parallel to the shoreline, resulting in long, narrow estuaries

Confluence
–
In geography, a confluence is the meeting of two or more bodies of water. The term is used to describe the meeting of tidal or other non-riverine bodies of water. A one-mile portion of the Industrial Canal in New Orleans accommodates the Gulf Intracoastal Waterway, niagara-on-the-Lake, Ontario, Canada is at the confluence of the Niagara River and Lake Ontario. The junction of the Green River and Colorado River forms the heart of Canyonlands National Park in Utahs Canyon Country, the Sangam, near Allahabad, India, where the sacred rivers Ganges and Yamuna meet to create one of the holiest places in Hinduism. The Ohio River is formed by the confluence of the Monongahela and Allegheny rivers, located in Pittsburgh, the Madison, Jefferson and Gallatin Rivers in Three Forks, Montana form the confluence of the Missouri River, one of the longest rivers in the United States. Kuala Lumpur, the capital of Malaysia, is at the confluence of the Gombak River and the Klang River. Passau known also as the Dreiflüssestadt, because the Danube River is joined there by the Inn River from the South, manaus, Brazil is on the Rio Negro near its confluence with the Amazon. It is the port and a hub for the regions extensive river system. Osijek, Croatia, is on the bank of the river Drava 25 km upstream of its confluence with the Danube. Belgrade, the capital of Serbia lies at the confluence of the Sava, the Hochelaga Archipelago, including the island and city of Montreal, is located at the confluence of the St. Lawrence River and Ottawa River in Quebec, Canada. Winnipeg, Canada, is at the confluence of the Red River, the area is referred to as The Forks by locals, and has been an important trade location for over 6000 years. The confluence of the rivers Danube and Morava in Devín on the border between Slovakia and Austria, triangle of Three Emperors, former tripoint in Europe. Cairo, Illinois, in the United States, where the Ohio River flows into the Mississippi River, St. Louis, Missouri, is built just south of the confluence of the Mississippi River and the Missouri River. Lyon, France is located on the confluence of the Saône and Rhone rivers, lytton, British Columbia, Canada, is located at the confluence of the muddy Fraser River and the clearer Thompson River. The confluence between the Franklin River and Gordon River in south-western Tasmania The confluence of the Snake and Columbia River at the Tri-Cities of Washington, the confluence of the rivers Pivka and Rak is one of the largest subterranean confluences in Europe. The confluence at Lokoja, Nigeria, where the Niger and Benue rivers merge, the Sudanese capital of Khartoum, located at the confluence of the White Nile and the Blue Nile. This merging point is the beginning of the Nile, columbus, Ohio, in the United States is at the confluence of the Scioto and Olentangy rivers. Luang Prabang in Laos is at the confluence of the Mekong, River Kabul and River Swat at Attock, in Pakistan

Po (river)
–
The Po is a river that flows eastward across northern Italy. The Po flows either 652 km or 682 km – considering the length of the Maira, the headwaters of the Po are a spring seeping from a stony hillside at Pian del Re, a flat place at the head of the Val Po under the northwest face of Monviso. The Po ends at a delta projecting into the Adriatic Sea near Venice and it has a drainage area of 74,000 km² in all,70,000 in Italy, of which 41,000 is in montane environments and 29,000 on the plain. The Po is the longest river in Italy, at its widest point its width is 503 m, the Po extends along the 45th parallel north. The river flows through many important Italian cities, including Turin, Piacenza and it is connected to Milan through a net of channels called navigli, which Leonardo da Vinci helped design. Near the end of its course, it creates a delta at the southern part of which is Comacchio. The Po valley was the territory of the Roman Cisalpine Gaul, divided into Cispadane Gaul, the Po begins in the Alps, and is in Italy, and flows eastward. The river is subject to heavy flooding, consequently, over half its length is controlled with argini, or dikes. The slope of the valley decreases from 0. 35% in the west to 0. 14% in the east and it is characterized by its large discharge. The vast valley around the Po is called the Po Basin or Po Valley, in 2002, more than 16 million people lived there, at the time nearly ⅓ of the population of Italy. The two main uses of the valley are for industry and for agriculture, both major uses. The industrial centres, such as Turin and Milan, are located on higher terrain and they rely for power on the numerous hydroelectric stations in or on the flanks of the Alps, and on the coal/oil power stations which use the water of the Po basin as coolant. Drainage from the north is mediated through several large, scenic lakes, the streams are now controlled by so many dams as to slow the rivers sedimentation rate, causing geologic problems. The main products of the farms around the river are cereals including – unusually for Europe – rice, the latter method is the chief consumer of surface water, while industrial and human consumption use underground water. The Po Delta wetlands have been protected by the institution of two parks in the regions in which it is situated, Veneto and Emilia-Romagna. The Po Delta Regional Park in Emilia-Romagna, the largest, consists of four parcels of land on the bank of the Po. Executive authority resides in an assembly of the presidents of the provinces, the mayors of the comuni and they employ a Technical-Scientific Committee and a Park Council to carry out directives. In 1999 the park was designated a World Heritage Site by UNESCO and was added to Ferrara, City of the Renaissance, the 53,653 ha of the park contain wetlands, forest, dunes and salt pans

United States Geological Survey
–
The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its resources. The organization has four science disciplines, concerning biology, geography, geology. The USGS is a research organization with no regulatory responsibility. The USGS is a bureau of the United States Department of the Interior, the USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, the current motto of the USGS, in use since August 1997, is science for a changing world. The agencys previous slogan, adopted on the occasion of its anniversary, was Earth Science in the Public Service. Prompted by a report from the National Academy of Sciences, the USGS was created, by a last-minute amendment and it was charged with the classification of the public lands, and examination of the geological structure, mineral resources, and products of the national domain. This task was driven by the need to inventory the vast lands added to the United States by the Louisiana Purchase in 1803, the legislation also provided that the Hayden, Powell, and Wheeler surveys be discontinued as of June 30,1879. Clarence King, the first director of USGS, assembled the new organization from disparate regional survey agencies, after a short tenure, King was succeeded in the directors chair by John Wesley Powell. Administratively, it is divided into a Headquarters unit and six Regional Units, Other specific programs include, Earthquake Hazards Program monitors earthquake activity worldwide. The National Earthquake Information Center in Golden, Colorado on the campus of the Colorado School of Mines detects the location, the USGS also runs or supports several regional monitoring networks in the United States under the umbrella of the Advanced National Seismic System. The USGS informs authorities, emergency responders, the media, and it also maintains long-term archives of earthquake data for scientific and engineering research. It also conducts and supports research on long-term seismic hazards, USGS has released the UCERF California earthquake forecast. The USGS National Geomagnetism Program monitors the magnetic field at magnetic observatories and distributes magnetometer data in real time, the USGS operates the streamgaging network for the United States, with over 7400 streamgages. Real-time streamflow data are available online, since 1962, the Astrogeology Research Program has been involved in global, lunar, and planetary exploration and mapping. USGS operates a number of related programs, notably the National Streamflow Information Program. USGS Water data is available from their National Water Information System database

Missouri River
–
The Missouri River is the longest river in North America. Rising in the Rocky Mountains of western Montana, the Missouri flows east and south for 2,341 miles before entering the Mississippi River north of St. Louis, Missouri. The river takes drainage from a populated, semi-arid watershed of more than half a million square miles. When combined with the lower Mississippi River, it forms the fourth longest river system. For over 12,000 years, people have depended on the Missouri River and its tributaries as a source of sustenance and transportation. More than ten major groups of Native Americans populated the watershed, most leading a nomadic lifestyle, the Missouri River was one of the main routes for the westward expansion of the United States during the 19th century. The growth of the fur trade in the early 1800s laid much of the groundwork as trappers explored the region, pioneers headed west en masse beginning in the 1830s, first by covered wagon, then by the growing numbers of steamboats entering service on the river. Former Native American lands in the watershed were taken over by settlers, leading to some of the most longstanding, during the 20th century, the Missouri River basin was extensively developed for irrigation, flood control and the generation of hydroelectric power. Fifteen dams impound the main stem of the river, with more on tributaries. Meanders have been cut and the river channelized to improve navigation, from the Rocky Mountains of Montana and Wyoming, three streams rise to form the headwaters of the Missouri River. The longest begins near Browers Spring,9,100 feet above sea level, on the southeastern slopes of Mount Jefferson in the Centennial Mountains. Flowing west then north, it runs first in Hell Roaring Creek, then west into the Red Rock, swings northeast to become the Beaverhead and these two streams then flow north and northwest into Montana. The Missouri River officially starts at the confluence of the Jefferson and Madison in Missouri Headwaters State Park near Three Forks, Montana, the Missouri then passes through Canyon Ferry Lake, a reservoir west of the Big Belt Mountains. Issuing from the mountains near Cascade, the flows northeast to the city of Great Falls, where it drops over the Great Falls of the Missouri. Farther on, the passes through the Fort Peck Dam, and immediately downstream. At the confluence, the Yellowstone is actually the larger river, the Missouri then meanders east past Williston and into Lake Sakakawea, the reservoir formed by Garrison Dam. Below the dam the Missouri receives the Knife River from the west and flows south to Bismarck, the capital of North Dakota and it slows into the Lake Oahe reservoir just before the Cannonball River confluence. While it continues south, eventually reaching Oahe Dam in South Dakota, the Missouri makes a bend to the southeast as it winds through the Great Plains, receiving the Niobrara River and many smaller tributaries from the southwest
