Isle of Wight
–
The Isle of Wight /ˈaɪl əv ˈwaɪt/ is a county and the largest and second-most populous island in England. It is located in the English Channel, about 4 miles off the coast of Hampshire, the island has resorts that have been holiday destinations since Victorian times, and is known for its mild climate, coastal scenery, and verdant landscape of fields, downland and chines. The island has been home to the poets Swinburne and Tennyson and to Queen Victoria and it has a maritime and industrial tradition including boat building, sail making, the manufacture of flying boats, the hovercraft, and Britains space rockets. The island hosts annual festivals including the Isle of Wight Festival. It has well-conserved wildlife and some of the richest cliffs and quarries for dinosaur fossils in Europe, the Isle was owned by a Norman family until 1293 and was earlier a kingdom in its own right. Rural for most of its history, its Victorian fashionability and the affordability of holidays led to significant urban development during the late 19th. The island was part of Hampshire until 1890 when it became its own administrative county, apart from a shared police force, there is now no administrative link with Hampshire, although a combined local authority with Portsmouth and Southampton is being considered. Until 1995 the island had a governor, the quickest public transport link to the mainland is the hovercraft from Ryde to Southsea, while three ferry and two catamaran services cross the Solent to Southampton, Lymington and Portsmouth. During the Ice Age, sea levels were lower and the Solent was part of a river flowing south east from current day Poole Harbour towards mid-Channel. As sea levels rose, the valley became flooded. The first inhabitants are assumed to have been hunter-gatherers migrating by land during the Paleolithic or Old Stone Age period, as the ice age began to recede. From the Neolithic era onwards, there are indications that the island had wide trading links, with a port at Bouldnor, evidence of Bronze Age tin trading, caesar reported that the Belgae took the Isle of Wight in about 85 BC and gave its name as Vectis. The Roman historian Suetonius mentions that the island was captured by the commander Vespasian, the Romans built no towns or roads on the island, but the remains of at least seven Roman villas have been found, indicating the prosperity of local agriculture. During the Dark Ages the island was settled by Jutes as the kingdom of Wihtwara under King Arwald. In 685 it was invaded by Caedwalla, who tried to replace the inhabitants with his own followers and it suffered especially from Viking raids, and was often used as a winter base by Viking raiders when they were unable to reach Normandy. Later, both Earl Tostig and his brother Harold Godwinson held manors on the island, the Norman Conquest of 1066 created the position of Lord of the Isle of Wight, the island being given by William the Conqueror to his kinsman William FitzOsbern. Carisbrooke Priory and the fort of Carisbrooke Castle were then founded, allegiance was sworn to FitzOsbern rather than the king, the Lordship was subsequently granted to the de Redvers family by Henry I, after his succession in 1100. For nearly 200 years the island was a semi-independent feudal fiefdom, the final private owner was the Countess Isabella de Fortibus, who, on her deathbed in 1293, was persuaded to sell it to Edward I

Alaska
–
Alaska is a U. S. state located in the northwest extremity of North America. To the north are the Chukchi and Beaufort seas–the southern parts of the Arctic Ocean, the Pacific Ocean lies to the south and southwest. Alaska is the largest state in the United States by area, the 3rd least populous, approximately half of Alaskas residents live within the Anchorage metropolitan area. Alaskas economy is dominated by the fishing, natural gas, military bases and tourism are also a significant part of the economy. The United States purchased Alaska from the Russian Empire on March 30,1867, the area went through several administrative changes before becoming organized as a territory on May 11,1912. It was admitted as the 49th state of the U. S. on January 3,1959, the name Alaska was introduced in the Russian colonial period when it was used to refer to the peninsula. It was derived from an Aleut, or Unangam idiom, which refers to the mainland of Alaska. Literally, it means object to which the action of the sea is directed, Alaska is the northernmost and westernmost state in the United States and has the most easterly longitude in the United States because the Aleutian Islands extend into the Eastern Hemisphere. Alaska is the only non-contiguous U. S. state on continental North America and it is technically part of the continental U. S. but is sometimes not included in colloquial use, Alaska is not part of the contiguous U. S. often called the Lower 48. The capital city, Juneau, is situated on the mainland of the North American continent but is not connected by road to the rest of the North American highway system. Alaskas territorial waters touch Russias territorial waters in the Bering Strait, as the Russian Big Diomede Island, Alaska has a longer coastline than all the other U. S. states combined. Alaska is the largest state in the United States by total area at 663,268 square miles, over twice the size of Texas, Alaska is larger than all but 18 sovereign countries. Counting territorial waters, Alaska is larger than the area of the next three largest states, Texas, California, and Montana. It is also larger than the area of the 22 smallest U. S. states. Also referred to as the Panhandle or Inside Passage, this is the region of Alaska closest to the rest of the United States, as such, this was where most of the initial non-indigenous settlement occurred in the years following the Alaska Purchase. The region is dominated by the Alexander Archipelago as well as the Tongass National Forest and it contains the state capital Juneau, the former capital Sitka, and Ketchikan, at one time Alaskas largest city. The Alaska Marine Highway provides a vital transportation link throughout the area. The Interior is the largest region of Alaska, much of it is uninhabited wilderness, Fairbanks is the only large city in the region

Meander
–
A meander, in general, is a bend in a sinuous watercourse or river. A meander forms when moving water in a stream erodes the outer banks and widens its valley, a stream of any volume may assume a meandering course, alternately eroding sediments from the outside of a bend and depositing them on the inside. The result is a pattern as the stream meanders back. When a meander gets cut off from the stream, an oxbow lake forms. Over time meanders migrate downstream, sometimes in such a time as to create civil engineering problems for local municipalities attempting to maintain stable roads. There is not yet full consistency or standardization of scientific terminology used to describe watercourses, a variety of symbols and schemes exist. Parameters based on mathematical formulae or numerical data vary as well, unless otherwise defined in a specific scheme meandering and sinuosity here are synonymous and mean any repetitious pattern of bends, or waveforms. In some schemes, meandering applies only to rivers with exaggerated circular loops or secondary meanders, sinuosity is one of the channel types that a stream may assume over all or part of its course. All streams are sinuous at some time in their history over some part of their length. The term derives from the Meander River located in present-day Turkey and known to the Ancient Greeks as Μαίανδρος Maiandros and its course is so exceedingly winding that everything winding is called meandering. The Meander River is located south of Izmir, east of the ancient Greek town of Miletus, now, Milet and it flows through a graben in the Menderes Massif, but has a flood plain much wider than the meander zone in its lower reach. Its modern Turkish name is the Büyük Menderes River, when a fluid is introduced to an initially straight channel which then bends, the sidewalls induce a pressure gradient that causes the fluid to alter course and follow the bend. From here, two opposing processes occur, irrotational flow and secondary flow, for a river to meander, secondary flow must dominate. Irrotational flow, From Bernoullis equations, high pressure results in low velocity, therefore, in the absence of secondary flow we would expect low fluid velocity at the outside bend and high fluid velocity at the inside bend. This classic fluid mechanics result is irrotational vortex flow, in the context of meandering rivers, its effects are dominated by those of secondary flow. Secondary flow, A force balance exists between pressure forces pointing to the bend of the river and centrifugal forces pointing to the outside bend of the river. In the context of meandering rivers, a boundary layer exists within the layer of fluid that interacts with the river bed. Inside that layer and following standard boundary-layer theory, the velocity of the fluid is effectively zero, centrifugal force, which depends on velocity, is also therefore effectively zero

Albany County, Wyoming
–
Albany County is a county in the U. S. state of Wyoming. As of the 2010 census, the population was 36,299 and its county seat is Laramie, the site of the University of Wyoming. It is north from the Colorado state line, Albany County comprises the Laramie, WY Micropolitan Statistical Area. Albany County was organized December 16,1868, from Laramie County in Dakota Territory and it became a county in Wyoming Territory when that territorys government was formally organized on May 19,1869. Charles D. Bradley, a member of the legislature of the Dakota Territory named the county for Albany, New York, in 1875, Albany County lost territory when Crook County and Johnson County were created by the legislature of the Wyoming Territory. Converse County was created with land ceded by Albany County in 1888, the boundaries of the county were final at that time except for minor adjustments in 1911 and 1955. According to the U. S. Census Bureau, the county has an area of 4,309 square miles. Highway 30 U. S. Highway 287 WYO230 WYO130 At the 2000 census, the population density was 8 per square mile. There were 15,215 housing units at a density of 4 per square mile. The racial makeup of the county was 91. 32% White,1. 11% Black or African American,0. 95% Native American,1. 7% Asian,0. 06% Pacific Islander,2. 65% from other races, and 2. 22% from two or more races. 7. 49% of the population were Hispanic or Latino of any race,24. 4% were of German,11. 1% English,10. 2% Irish and 6. 1% American ancestry. 31. 4% of all households were made up of individuals and 6. 2% had someone living alone who was 65 years of age or older, the average household size was 2.23 and the average family size was 2.84. 18. 4% of the population were under the age of 18,28. 2% from 18 to 24,26. 1% from 25 to 44,19. 1% from 45 to 64, the median age was 27 years.

Moraine
–
A moraine is any glacially formed accumulation of unconsolidated glacial debris that occurs in both currently and formerly glaciated regions on Earth, through geomorphological processes. Moraines are formed from debris previously carried along by a glacier, lateral moraines are formed at the side of the ice flow and terminal moraines at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines, till-covered areas with irregular topography, moraines may be composed of debris ranging in size from silt-sized glacial flour to large boulders. The debris is typically sub-angular to rounded in shape, moraines may be on the glacier’s surface or deposited as piles or sheets of debris where the glacier has melted. Moraines may form through a number of processes, depending on the characteristics of sediment, the dynamics on the ice, moraine forming processes may be loosely divided into passive and active. Passive processes involve the placing of chaotic supraglacial sediments onto the landscape with limited reworking and these moraines are composed of supraglacial sediments from the ice surface. Active processes form or rework moraine sediment directly by the movement of ice and these form push moraines and thrust-block moraines, which are often composed of till and reworked proglacial sediment. Moraine may also form by the accumulation of sand and gravel deposits from glacial streams emanating from the ice margin and these fan deposits may coalesce to form a long moraine bank marking the ice margin. Several processes may combine to form and rework a single moraine, moraines can be classified either by origin, location with respect to a glacier or former glacier, or by shape. Some moraine types are only from ancient glaciers, while medial moraines of valley glaciers are poorly preserved. Lateral moraines are parallel ridges of debris deposited along the sides of a glacier, the unconsolidated debris can be deposited on top of the glacier by frost shattering of the valley walls and/or from tributary streams flowing into the valley. The till is carried along the glacial margin until the glacier melts, lateral moraines stand high because they protect the ice under them from the elements, causing it to melt or sublime less than the uncovered parts of the glacier. Multiple lateral moraines may develop as the glacier advances and retreats, ground moraines are till-covered areas with irregular topography and no ridges, often forming gently rolling hills or plains. They are accumulated at the base of the ice as lodgment till, in alpine glaciers, ground moraines are often found between the two lateral moraines. Ground moraines may be modified into drumlins by the overriding ice, Rogen moraines or ribbed moraines are a type of basal moraines that form a series of ribs perpendicular to the ice flow in an ice sheet. The depressions between the ribs are sometimes filled with water, making the Rogen moraines look like tigerstripes on aerial photographs, Rogen moraines are named after Lake Rogen in Härjedalen, Sweden, the landform’s type locality. End moraines, or terminal moraines, are ridges of unconsolidated debris deposited at the snout or end of the glacier and they usually reflect the shape of the glaciers terminus. Glaciers act much like a belt, carrying debris from the top of the glacier to the bottom where it deposits it in end moraines

High water mark
–
A high water mark is a point that represents the maximum rise of a body of water over land. Such a mark is often the result of a flood, but high water marks may reflect an all-time high, knowledge of the high water mark for an area is useful in managing the development of that area, particularly in making preparations for flood surges. High water marks from floods have been measured for planning purposes since at least as far back as the civilizations of ancient Egypt. This may be a flood level sign or other marker. A high water mark is not necessarily an actual physical mark, a landscape marking left by the high water mark of ordinary tidal action may be called a strandline and is typically composed of debris left by high tide. The area at the top of a beach where debris is deposited is an example of this phenomenon, where there are tides, this line is formed by the highest position of the tide, and moves up and down the beach on a fortnightly cycle. The debris is chiefly composed of rotting seaweed, but can include a large amount of litter, either from ships at sea or from sewage outflows. The strandline is an important habitat for a variety of animals, one kind of high water mark is the ordinary high water mark or average high water mark, the high water mark that can be expected to be produced by a body of water in non-flood conditions. The ordinary high water mark may have significance and is often being used to demarcate property boundaries. The ordinary high water mark has also used for other legal demarcations. For the purposes of Section 404 of the Clean Water Act, for the purposes of Sections 9 and 10 of the Rivers and Harbors Act of 1899, the OHWM defines the lateral limits of federal jurisdiction over traditional navigable waters of the US. Likewise, many states use similar definitions of the OHWM for the purposes of their own regulatory programs, in 2016, the Court of Appeals of Indiana ruled that land below the OHWM along Lake Michigan is held by the state in trust for public use. In Australia, the definition of the Mean High Water Mark is. the line of the high tide between the highest tide of each lunar month and the lowest each lunar month averaged over the year.

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
8.
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
9.
Flood
–
A flood is an overflow of water that submerges land which is usually dry. The European Union Floods Directive defines a flood as a covering by water of land not normally covered by water, in the sense of flowing water, the word may also be applied to the inflow of the tide. Floods can also occur in rivers when the flow exceeds the capacity of the river channel. Floods often cause damage to homes and businesses if they are in the flood plains of rivers. Some floods develop slowly, while others such as floods, can develop in just a few minutes. Additionally, floods can be local, impacting a neighborhood or community, or very large, the word flood comes from the Old English flod, a word common to Germanic languages. Deluge myths are stories of a great flood sent by a deity or deities to destroy civilization as an act of divine retribution. Floods can happen on flat or low-lying areas when water is supplied by rainfall or snowmelt more rapidly than it can infiltrate or run off. The excess accumulates in place, sometimes to hazardous depths, surface soil can become saturated, which effectively stops infiltration, where the water table is shallow, such as a floodplain, or from intense rain from one or a series of storms. Infiltration also is slow to negligible through frozen ground, rock, concrete, paving, areal flooding begins in flat areas like floodplains and in local depressions not connected to a stream channel, because the velocity of overland flow depends on the surface slope. Endorheic basins may experience flooding during periods when precipitation exceeds evaporation. Floods occur in all types of river and stream channels, from the smallest ephemeral streams in humid zones to normally-dry channels in arid climates to the worlds largest rivers. When overland flow occurs on tilled fields, it can result in a flood where sediments are picked up by run off. Localized flooding may be caused or exacerbated by drainage obstructions such as landslides, ice, debris, slow-rising floods most commonly occur in large rivers with large catchment areas. The increase in flow may be the result of sustained rainfall, rapid snow melt, monsoons, the cause may be localized convective precipitation or sudden release from an upstream impoundment created behind a dam, landslide, or glacier. In one instance, a flood killed eight people enjoying the water on a Sunday afternoon at a popular waterfall in a narrow canyon. Without any observed rainfall, the rate increased from about 50 to 1,500 cubic feet per second in just one minute. Two larger floods occurred at the site within a week

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

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
