A stream is a continuous body of surface water flowing within the bed and banks of a channel . 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 usually called rivers , while smaller, less voluminous and more intermittent streams are known as streamlets , brooks or creeks .
96-438: In Australian English , a billabong ( / ˈ b ɪ l ə b ɒ ŋ / BIL -ə-bong ) is a small body of water , usually permanent. It is usually an oxbow lake caused by a change in course of a river or creek , but other types of small lakes , ponds or waterholes are also called billabongs. The term is likely borrowed from Wiradjuri , an Aboriginal Australian language of New South Wales . The word billabong

Mary Grant Bruce wrote a series of books, known as The Billabong Series , depicting the adventures of the Linton family, who live at Billabong station from around 1911 until
288-424: A lake , bay or ocean but joins another river (a parent river). Sometimes also called a branch or fork. A distributary , or a distributary channel , is a stream that branches off and flows away from a main stream channel, and the phenomenon is known as river bifurcation . Distributaries are common features of river deltas , and are often found where a valleyed stream enters wide flatlands or approaches
384-524: A stroller is usually called a pram in Victoria, Western Australia, South Australia, New South Wales, and Tasmania. Preference for some synonymous words also differ between states. Garbage (i.e., garbage bin, garbage truck) dominates over rubbish in New South Wales and Queensland, while rubbish is more popular in Victoria, Tasmania, Western Australia and South Australia. Additionally,
480-406: A "dinky-di Aussie" is a "true Australian". Australian poetry , such as " The Man from Snowy River ", as well as folk songs such as " Waltzing Matilda ", contain many historical Australian words and phrases that are understood by Australians even though some are not in common usage today. Australian English, in common with British English , uses the word mate to mean friend , as well as
576-403: A bed armor layer, and other depositional features, plus well defined banks due to bank erosion, are good identifiers when assessing for perennial streams. Particle size will help identify a perennial stream. Perennial streams cut through the soil profile, which removes fine and small particles. By assessing areas for relatively coarse material left behind in the stream bed and finer sediments along
672-658: A continuous aquatic habitat until they reach maturity. Crayfish and other crustaceans , snails , bivalves (clams), and aquatic worms also indicate the stream is perennial. These require a persistent aquatic environment for survival. Fish and amphibians are secondary indicators in assessment of a perennial stream because some fish and amphibians can inhabit areas without persistent water regime. When assessing for fish, all available habitat should be assessed: pools, riffles, root clumps and other obstructions. Fish will seek cover if alerted to human presence, but should be easily observed in perennial streams. Amphibians also indicate
768-470: A continuous or intermittent stream. The same non-perennial channel might change characteristics from intermittent to ephemeral over its course. Washes can fill up quickly during rains, and there may be a sudden torrent of water after a thunderstorm begins upstream, such as during monsoonal conditions. In the United States, an intermittent or seasonal stream is one that only flows for part of
864-422: A drainage network. Although each tributary has its own source, international practice is to take the source farthest from the river mouth as the source of the entire river system, from which the most extended length of the river measured as the starting point is taken as the length of the whole river system, and that furthest starting point is conventionally taken as the source of the whole river system. For example,
960-572: A full vowel ( /ˈnesəseɹiː, ˈmalbeɹiː, ˈmætɹəməʉniː/ ) or a schwa ( /ˈnesəsəɹiː, ˈmalbəɹiː, ˈmætɹəməniː/ ). Although some words like necessary are almost universally pronounced with the full vowel, older generations of Australians are relatively likely to pronounce these affixes with a schwa as is typical in British English. Meanwhile, younger generations are relatively likely to use a full vowel. Words ending in unstressed -ile derived from Latin adjectives ending in -ilis are pronounced with
1056-415: A full vowel, so that fertile /ˈfɜːtɑɪl/ sounds like fur tile rather than rhyming with turtle /ˈtɜːtəl/ . In addition, miscellaneous pronunciation differences exist when compared with other varieties of English in relation to various isolated words, with some of those pronunciations being unique to Australian English. For example: Relative to many other national dialect groupings, Australian English

#17327825510371152-483: A fully backed allophone of /ʉː/ , transcribed [ʊː] , is common before /l/ . As a result, the pairs full/fool and pull/pool differ phonetically only in vowel length for those speakers. The usual allophone for /ʉː/ is further forward in Queensland and New South Wales than Victoria. The General Australian accent serves as the standard variety of English across the country. According to linguists, it emerged during
1248-410: A greater part of the year. Many billabongs are of cultural significance and social importance to Aboriginal and Torres Strait Islander peoples, and used as sources of fresh water as well as other resources. Water is an intrinsic part of Country , and essential resource during drought or dry seasons , and they have many intricate ways of understanding how to find water. The Ngan'gi peoples in
1344-538: A historical dictionary documenting the history of Australian English vocabulary and idiom. The most obvious way in which Australian English is distinctive from other varieties of English is through its unique pronunciation. It shares most similarity with New Zealand English . Like most dialects of English, it is distinguished primarily by the phonetic quality of its vowels. The vowels of Australian English can be divided according to length. The long vowels, which include monophthongs and diphthongs , mostly correspond to
1440-400: A large flood. Billabongs are usually formed when the path of a creek or river changes due to bank erosion , leaving the former channel deprived of further inflow and becoming a dead-end gully holding only residual water that has not yet drained or evaporated. As a result of the arid climate of many parts of Australia, these "dead rivers" often fill with water seasonally but can be dry for
1536-490: A low area of ground that was part of a river in the past and that only fills up with water from the river during a flood". In a 2009 study, billabongs of the Channel Country (a region of outback Australia whose name derives from the numerous intertwined rivulets that cross it) are alternatively termed waterholes, and described as "enlarged channel segments along the main course of the river... typically occur[ring] at
1632-404: A path into mines or other underground chambers. According to official U.S. definitions, the channels of intermittent streams are well-defined, as opposed to ephemeral streams, which may or may not have a defined channel, and rely mainly on storm runoff, as their aquatic bed is above the water table . An ephemeral stream does not have the biological, hydrological, and physical characteristics of
1728-412: A perennial stream and include tadpoles , frogs , salamanders , and newts . These amphibians can be found in stream channels, along stream banks, and even under rocks. Frogs and tadpoles usually inhabit shallow and slow moving waters near the sides of stream banks. Frogs will typically jump into water when alerted to human presence. Well defined river beds composed of riffles, pools, runs, gravel bars,
1824-483: A perennial stream, fine sediment may cling to riparian plant stems and tree trunks. Organic debris drift lines or piles may be found within the active overbank area after recent high flow. Streams, headwaters, and streams flowing only part of the year provide many benefits upstream and downstream. They defend against floods, remove contaminants, recycle nutrients that are potentially dangerous as well as provide food and habitat for many forms of fish. Such streams also play
1920-556: A range of forms which developed differently in different parts of Australia, and are said to vary along a continuum, from forms close to Standard Australian English to more non-standard forms. There are distinctive features of accent, grammar, words and meanings, as well as language use. Academics have noted the emergence of numerous ethnocultural dialects of Australian English that are spoken by people from some minority non-English speaking backgrounds. These ethnocultural varieties contain features of General Australian English as adopted by
2016-406: A slow-moving wetted channel or stagnant area. This is evidence that iron-oxidizing bacteria are present, indicating persistent expression of oxygen-depleted ground water. In a forested area, leaf and needle litter in the stream channel is an additional indicator. Accumulation of leaf litter does not occur in perennial streams since such material is continuously flushed. In the adjacent overbank of

#17327825510372112-486: A stream as intermittent, "showing interruptions in time or space". Generally, streams that flow only during and immediately after precipitation are termed ephemeral . There is no clear demarcation between surface runoff and an ephemeral stream, and some ephemeral streams can be classed as intermittent—flow all but disappearing in the normal course of seasons but ample flow (backups) restoring stream presence — such circumstances are documented when stream beds have opened up
2208-424: A stream is a critical factor in determining its character and is entirely determined by its base level of erosion. The base level of erosion is the point at which the stream either enters the ocean, a lake or pond, or enters a stretch in which it has a much lower gradient, and may be specifically applied to any particular stretch of a stream. In geological terms, the stream will erode down through its bed to achieve
2304-574: A stream is controlled by three inputs – surface runoff (from precipitation or meltwater ), daylighted subterranean water , and surfaced groundwater ( spring water ). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls. Streams are important as conduits in
2400-1044: A stream or small river, whereas in the UK it is typically a watercourse in a marshy area; paddock in Australia means field, whereas in the UK it means a small enclosure for livestock; bush or scrub in Australia, as in North America, means a natural, uncultivated area of vegetation or flora, whereas in England they are commonly used only in proper names (such as Shepherd's Bush and Wormwood Scrubs ). Some elements of Aboriginal languages have been adopted by Australian English —mainly as names for places, flora and fauna (for example dingo ) and local culture. Many such are localised, and do not form part of general Australian use, while others, such as kangaroo , boomerang , budgerigar , wallaby and so on have become international. Other examples are cooee and hard yakka . The former
2496-524: A thin layer called sheet wash, combined with a network of tiny rills, which together form the sheet runoff; when this water is focused in a channel, a stream is born. Some rivers and streams may begin from lakes or ponds. Freshwater's primary sources are precipitation and mountain snowmelt. However, rivers typically originate in the highlands, and are slowly created by the erosion of mountain snowmelt into lakes or rivers. Rivers usually flow from their source topographically, and erode as they pass until they reach
2592-499: A vital role in preserving our drinking water quality and supply, ensuring a steady flow of water to surface waters and helping to restore deep aquifers. The extent of land basin drained by a stream is termed its drainage basin (also known in North America as the watershed and, in British English, as a catchment). A basin may also be composed of smaller basins. For instance, the Continental Divide in North America divides
2688-567: A wave of academic interest and codification during the 20th century which resulted in Australian English becoming established as an endonormative variety with its own internal norms and standards. This culminated in publications such as the 1981 first edition of the Macquarie Dictionary , a major English language dictionary based on Australian usage, and the 1988 first edition of The Australian National Dictionary ,
2784-414: Is a large natural stream that is much wider and deeper than a creek and not easily fordable, and may be a navigable waterway . The linear channel between the parallel ridges or bars on a shoreline beach or river floodplain, or between a bar and the shore. Also called a swale . A tributary is a contributory stream to a larger stream, or a stream which does not reach a static body of water such as
2880-612: Is also the main language used in compulsory education, as well as federal, state and territorial legislatures and courts. Australian English began to diverge from British and Hiberno-English after the First Fleet established the Colony of New South Wales in 1788. Australian English arose from a dialectal melting pot created by the intermingling of early settlers who were from a variety of dialectal regions of Great Britain and Ireland , though its most significant influences were
2976-593: Is first recorded in Australian English in 1836, referring to the Bell River in south-eastern New South Wales, when explorer Thomas Mitchell records the Aboriginal name of the river as "Billibang". It is first recorded in its later, more general sense, by J. Allen in 1853: "This station is situated about half-a-mile inland, over a 'billy-bong' (the native name for a small creek or backwater)". It

3072-402: Is found across the continent and is relatively more prominent in rural and outer-suburban areas. A largely historical Cultivated sociocultural variant, which adopted features of British Received Pronunciation and which was commonplace in official media during the early 20th century, had become largely extinct by the onset of the 21st century. Australian Aboriginal English is made up of
3168-683: Is generally retained in other consonant clusters . In common with most varieties of Scottish English and American English , the phoneme /l/ is pronounced by Australians as a "dark" (velarised) l ( [ɫ] ) in almost all positions, unlike other dialects such as Received Pronunciation , Hiberno (Irish) English , etc. Differences in stress, weak forms and standard pronunciation of isolated words occur between Australian English and other forms of English, which while noticeable do not impair intelligibility. The affixes -ary , -ery , -ory , -bury , -berry and -mony (seen in words such as necessary, mulberry and matrimony ) can be pronounced either with
3264-441: Is known as surface hydrology and is a core element of environmental geography . A brook is a stream smaller than a creek, especially one that is fed by a spring or seep . It is usually small and easily forded . A brook is characterised by its shallowness. A creek ( / k r iː k / ) or crick ( / k r ɪ k / ): In hydrography, gut is a small creek; this is seen in proper names in eastern North America from
3360-511: Is most likely derived from the Wiradjuri language of southern New South Wales , which "describes a pond or pool of water that is left behind when a river alters course or after floodwaters recede". According to the Macquarie Dictionary (2005), the original term bilabaŋ means "a watercourse that runs only after rain", with bila meaning "river", and possibly combined with bong or bung , meaning "dead". The attribution of this last part of
3456-516: Is mostly evident in phonology. Although Australian English is relatively homogeneous, there are some regional variations. The dialects of English spoken in the various states and territories of Australia differ slightly in vocabulary and phonology. Most regional differences are in word usage. Swimming clothes are known as cossies , /ˈkɔziːz/ togs or swimmers in New South Wales, togs in Queensland, and bathers in Victoria, Tasmania, Western Australia and South Australia. What Queensland calls
3552-454: Is no exception. Australian English is uniformly non-rhotic ; that is, the /ɹ/ sound does not appear at the end of a syllable or immediately before a consonant. As with many non-rhotic dialects, linking /ɹ/ can occur when a word that has a final ⟨r⟩ in the spelling comes before another word that starts with a vowel. An intrusive /ɹ/ may similarly be inserted before a vowel in words that do not have ⟨r⟩ in
3648-623: Is not recorded in the first edition of the Oxford English Dictionary (prepared 1882–1888), published before the later contributions of the Australian academic Edward Ellis Morris . It appears in Morris's Austral English: A Dictionary of Australasian Words (1898). A 2004 thesis suggests that the term could be of Scottish Gaelic origin, derived from words for "lip" or "mouth" and "river". Definitions vary. A billabong
3744-400: Is often defined as an oxbow lake , an isolated crescentic pond left behind after a river loop is cut off when the river channel changes course. Merriam-Webster defines the word as: "1. (a) a blind channel leading out from a river; (b) a usually dry streambed that is filled seasonally", or 2. "a backwater forming a stagnant pool" The Cambridge Dictionary describes it as "In Australia,
3840-636: Is relatively homogeneous across the country. Some relatively minor regional differences in pronunciation exist. A limited range of word choices is strongly regional in nature. Consequently, the geographical background of individuals may be inferred if they use words that are peculiar to particular Australian states or territories and, in some cases, even smaller regions. In addition, some Australians speak creole languages derived from Australian English, such as Australian Kriol , Torres Strait Creole and Norfuk . Academic research has also identified notable sociocultural variation within Australian English, which
3936-465: Is sometimes omitted in broader Australian English. For instance, "really good" can become "real good". Australia's switch to the metric system in the 1970s changed most of the country's vocabulary of measurement from imperial to metric measures. Since the switch to metric, heights of individuals are listed in centimetres on official documents and distances by road on signs are listed in terms of kilometres and metres . Stream The flow of

4032-425: Is sometimes termed a "young" or "immature" stream, and the later state a "mature" or "old" stream. Meanders are looping changes of direction of a stream caused by the erosion and deposition of bank materials. These are typically serpentine in form. Typically, over time the meanders gradually migrate downstream. If some resistant material slows or stops the downstream movement of a meander, a stream may erode through
4128-480: Is the set of varieties of the English language native to Australia . It is the country's common language and de facto national language ; while Australia has no official language , English is the first language of the majority of the population , and has been entrenched as the de facto national language since British settlement , being the only language spoken in the home for 72% of Australians . It

Hard yakka means "hard work" and is derived from yakka , from the Jagera /Yagara language once spoken in the Brisbane region. The word bung , meaning "dead" was originally a Yagara word which was used in
4320-456: Is usually called a creek and marked on topographic maps with a solid blue line. There are five generic classifications: "Macroinvertebrate" refers to easily seen invertebrates , larger than 0.5 mm, found in stream and river bottoms. Macroinvertebrates are larval stages of most aquatic insects and their presence is a good indicator that the stream is perennial. Larvae of caddisflies , mayflies , stoneflies , and damselflies require
4416-626: The Australian gold rushes in the 1850s began a large wave of immigration , during which about two percent of the population of the United Kingdom emigrated to the colonies of New South Wales and Victoria . The Gold Rushes brought immigrants and linguistic influences from many parts of the world. An example was the introduction of vocabulary from American English , including some terms later considered to be typically Australian, such as bushwhacker and squatter . This American influence
4512-632: The Daly River region of the Northern Territory continue to manage the billabongs' ecology in their Country. Water-holding frogs living in the billabongs can take up a lot of water before it burrows into the earth in the dry season, and Aboriginal peoples in desert environments can locate the frogs underground by various means. In the days since the colonisation of Australia , these were important landmarks for European settlers to identify, and many billabongs were given names relating to
4608-691: The Tombigbee River basin. Continuing in this vein, a component of the Mississippi River basin is the Ohio River basin, which in turn includes the Kentucky River basin, and so forth. Stream crossings are where streams are crossed by roads , pipelines , railways , or any other thing which might restrict the flow of the stream in ordinary or flood conditions. Any structure over or in a stream which results in limitations on
4704-713: The coastal plains around a lake or an ocean . They can also occur inland, on alluvial fans , or where a tributary stream bifurcates as it nears its confluence with a larger stream. Common terms for individual river distributaries in English-speaking countries are arm and channel . There are a number of regional names for a stream. A stream's source depends on the surrounding landscape and its function within larger river networks. While perennial and intermittent streams are typically supplied by smaller upstream waters and groundwater, headwater and ephemeral streams often derive most of their water from precipitation in
4800-510: The de facto standard dialect , which is perceived to be free of pronounced regional or sociocultural markers and is often used in the media. The earliest Australian English was spoken by the first generation of native-born colonists in the Colony of New South Wales from the end of the 18th century. These native-born children were exposed to a wide range of dialects from across the British Isles . Similar to early American English ,
4896-811: The pidgin widely spoken across Australia. Many towns or suburbs of Australia have also been influenced or named after Aboriginal words. The best-known example is the capital, Canberra , named after a local Ngunnawal language word thought to mean "women's breasts" or "meeting place". Litotes , such as "not bad", "not much" and "you're not wrong", are also used. Diminutives and hypocorisms are common and are often used to indicate familiarity. Some common examples are arvo (afternoon), barbie (barbecue), smoko (cigarette break), Aussie (Australian) and Straya (Australia). This may also be done with people's names to create nicknames (other English speaking countries create similar diminutives ). For example, "Gazza" from Gary, or "Smitty" from John Smith. The use of

The short vowels, consisting only of monophthongs, correspond to the RP lax vowels. There exist pairs of long and short vowels with overlapping vowel quality giving Australian English phonemic length distinction , which is also present in some regional south-eastern dialects of the UK and eastern seaboard dialects in
5088-480: The velocity of the stream. A perennial stream is one which flows continuously all year. Some perennial streams may only have continuous flow in segments of its stream bed year round during years of normal rainfall. Blue-line streams are perennial streams and are marked on topographic maps with a solid blue line. The word "perennial" from the 1640s, meaning "evergreen," is established in Latin perennis, keeping

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

Dangers to the ecological balance of billabongs include saltwater intrusion and introduced species . Feral animals have caused salt water to flow into Arafura Swamp , a large freshwater basin in the Top End in the Northern Territory, in which there are many permanent billabongs. Once a jolly swagman camped by
5376-519: The 19th century. General Australian is the dominant variety across the continent, and is particularly so in urban areas. The increasing dominance of General Australian reflects its prominence on radio and television since the latter half of the 20th century. Recent generations have seen a comparatively smaller proportion of the population speaking with the Broad sociocultural variant, which differs from General Australian in its phonology. The Broad variant

As with New Zealand English and General American English, the weak-vowel merger is complete in Australian English: unstressed /ɪ/ is merged into /ə/ ( schwa ), unless it is followed by a velar consonant. Examples of this feature are the following pairings, which are pronounced identically in Australian English: Rosa's and roses , as well as Lennon and Lenin . Other examples are
5664-533: The atmosphere either by evaporation from soil and water bodies, or by plant evapotranspiration. By infiltration some of the water sinks into the earth and becomes groundwater, much of which eventually enters streams. Most precipitated water is partially bottled up by evaporation or freezing in snow fields and glaciers. The majority of the water flows as a runoff from the ground; the proportion of this varies depending on several factors, such as climate, temperature, vegetation, types of rock, and relief. This runoff begins as
5760-525: The base level of erosion throughout its course. If this base level is low, then the stream will rapidly cut through underlying strata and have a steep gradient, and if the base level is relatively high, then the stream will form a flood plain and meander. Typically, streams are said to have a particular elevation profile , beginning with steep gradients, no flood plain, and little shifting of channels, eventually evolving into streams with low gradients, wide flood plains, and extensive meanders. The initial stage

Queensland's Department of Environment, Science and Innovation , in its Queensland Waterhole Classification Scheme, describes waterholes as "referred to by a range of different names (i.e. billabongs, lagoons and waterbodies)". Another source describes a billabong as "a large body of water", which may be formed from a section of cut-off river, but may also be formed from water left behind after

Internationally well-known examples of Australian terminology include outback , meaning a remote, sparsely populated area, the bush , meaning either a native forest or a country area in general, and g'day , a greeting. Dinkum , or fair dinkum means "true", "legitimate" or "is that true?", among other things, depending on context and inflection. The derivative dinky-di means "true" or devoted:
6432-509: The dialects of South East England . By the 1820s, the native-born colonists' speech was recognisably distinct from speakers in Britain and Ireland. Australian English differs from other varieties in its phonology , pronunciation , lexicon , idiom , grammar and spelling . Australian English is relatively consistent across the continent, although it encompasses numerous regional and sociocultural varieties . "General Australian" describes
6528-609: The end of a word or morpheme before any vowel in the same breath group. Examples of this feature are that the following pairs are pronounced similarly or identically: latter and ladder , as well as rated and raided . Yod -dropping generally occurs after /s/ , /l/ , /z/ , /θ/ but not after /t/ , /d/ and /n/ . Accordingly, suit is pronounced as /sʉːt/ , lute as /lʉːt/ , Zeus as /zʉːs/ and enthusiasm as /enˈθʉːziːæzəm/ . Other cases of /sj/ and /zj/ , as well as /tj/ and /dj/ , have coalesced to /ʃ/ , /ʒ/ , /tʃ/ and /dʒ/ respectively for many speakers. /j/
6624-652: The flow is reduced to a trickle or less. Typically torrents have Apennine rather than Alpine sources, and in the summer they are fed by little precipitation and no melting snow. In this case the maximum discharge will be during the spring and autumn. An intermittent stream can also be called a winterbourne in Britain, a wadi in the Arabic -speaking world or torrente or rambla (this last one from arabic origin) in Spain and Latin America. In Australia, an intermittent stream
6720-400: The following pairs, which rhyme in Australian English: abbott with rabbit , and dig it with bigot . Most varieties of Australian English exhibit only a partial trap-bath split . The words bath , grass and can't are always pronounced with the "long" /aː/ of father . Throughout the majority of the country, the "flat" /æ/ of man is the dominant pronunciation for the a vowel in
6816-447: The following words: dance , advance , plant , example and answer . The exception is the state of South Australia , where a more advanced trap-bath split is found, and where the dominant pronunciation of all the preceding words incorporates the "long" /aː/ of father . There is little variation in the sets of consonants used in different English dialects but there are variations in how these consonants are used. Australian English
6912-447: The form of rain and snow. Most of this precipitated water re-enters the atmosphere by evaporation from soil and water bodies, or by the evapotranspiration of plants. Some of the water proceeds to sink into the earth by infiltration and becomes groundwater, much of which eventually enters streams. Some precipitated water is temporarily locked up in snow fields and glaciers , to be released later by evaporation or melting. The rest of

The Kagera River, which flows into Lake Victoria near Bukoba's Tanzanian town , is the longest feeder, though sources do not agree on which is the Kagera's longest tributary and therefore the Nile's most remote source itself. To qualify as a stream, a body of water must be either recurring or perennial. Recurring (intermittent) streams have water in the channel for at least part of
7104-604: The late 1920s. Both Aboriginal Australians and European artists use billabongs as subject matter in painting. For example, Aboriginal painter Tjyllyungoo (Lance Chad) has a watercolour entitled Trees at a billabong . American avant-garde filmmaker Will Hindle produced a short film titled Billabong in 1969. Billabong is the name of an Australian brand of sportswear for surf, skateboard, and snowboard.

7200-405: The local areas. A billabong retains water longer than the original watercourse and may be the only accessible water in a large area. Billabongs are significant because they do not have outflow and can hold water longer than sections of rivers especially during drier season, thus serving important ecological functions as waterholes and habitats for freshwater animal and plant species, including
7296-683: The mainly easterly-draining Atlantic Ocean and Arctic Ocean basins from the largely westerly-flowing Pacific Ocean basin. The Atlantic Ocean basin, however, may be further subdivided into the Atlantic Ocean and Gulf of Mexico drainages. (This delineation is termed the Eastern Continental Divide .) Similarly, the Gulf of Mexico basin may be divided into the Mississippi River basin and several smaller basins, such as
7392-412: The meaning as "everlasting all year round," per "over" plus annus "year." This has been proved since the 1670s by the "living years" in the sense of botany. The metaphorical sense of "enduring, eternal" originates from 1750. They are related to "perennial." See biennial for shifts in vowels. Perennial streams have one or more of these characteristics: Absence of such characteristics supports classifying
7488-453: The neck between two legs of a meander to become temporarily straighter, leaving behind an arc-shaped body of water termed an oxbow lake or bayou . A flood may also cause a meander to be cut through in this way. The stream load is defined as the solid matter carried by a stream. Streams can carry sediment, or alluvium. The amount of load it can carry (capacity) as well as the largest object it can carry (competence) are both dependent on
7584-596: The origin of the Nile River is the confluence of the White Nile and the Blue Nile, but the source of the whole river system is in its upper reaches. If there is no specific designation, "length of the Nile" refers to the "river length of the Nile system", rather than to the length of the Nile river from the point where it is formed by a confluence of tributaries. The Nile's source is often cited as Lake Victoria, but
7680-511: The other states they may also be realised as monophthongs: [nɪː, skweː] . A feature common in Victorian English is salary–celery merger , whereby a Victorian pronunciation of Ellen may sound like Alan and Victoria's capital city Melbourne may sound like Malbourne to speakers from other states. There is also regional variation in /ʉː/ before /l/ (as in school and pool ). In some parts of Australia, notably Victoria,
7776-551: The other states. Accordingly, words such as dance , advance , plant , example and answer are pronounced with /aː/ (as in father ) far more frequently in South Australia while the older /æ/ (as in mad ) is dominant elsewhere in Australia. L -vocalisation is also more common in South Australia than other states. In Western Australian and Queensland English, the vowels in near and square are typically realised as centring diphthongs ( [nɪə, skweə] ), whereas in
7872-471: The process of dialect levelling and koineisation which ensued produced a relatively homogeneous new variety of English which was easily understood by all. Peter Miller Cunningham 's 1827 book Two Years in New South Wales described the distinctive accent and vocabulary that had developed among the native-born colonists. The dialects of South East England , including most notably the traditional Cockney dialect of London, were particularly influential on
7968-469: The relationship between CSA and CSD with a minimum catchment area established. Using the model for comparison in two basins in Tibet (Helongqu and Niyang River White Water), the results show that the critical support flow (Qc) of the housing dragon song is 0.0028 m /s. At the same time, the white water curvature is 0.0085 m /s. Besides, the critical support flow can vary with hydrologic climate conditions, and
8064-425: The side of the stream or within the floodplain will be a good indicator of persistent water regime. A perennial stream can be identified 48 hours after a storm. Direct storm runoff usually has ceased at this point. If a stream is still flowing and contributing inflow is not observed above the channel, the observed water is likely baseflow. Another perennial stream indication is an abundance of red rust material in
8160-463: The spelling in certain environments, namely after the long vowel /oː/ and after word final /ə/ . This can be heard in "law-r-and order", where an intrusive R is voiced between the AW and the A. As with North American English, intervocalic alveolar flapping is a feature of Australian English: prevocalic /t/ and /d/ surface as the alveolar tap [ɾ] after sonorants other than /m, ŋ/ as well as at
8256-572: The suffix -o originates in Irish : ó , which is both a postclitic and a suffix with much the same meaning as in Australian English. In informal speech, incomplete comparisons are sometimes used, such as "sweet as" (as in "That car is sweet as."). "Full", "fully" or "heaps" may precede a word to act as an intensifier (as in "The waves at the beach were heaps good."). This was more common in regional Australia and South Australia but has been in common usage in urban Australia for decades. The suffix "-ly"
8352-412: The use of the interrogative eh (also spelled ay or aye ), which is particularly associated with Queensland. Secret Santa ( ) and Kris Kringle are used in all states, with the former being more common in Queensland. The most pronounced variation in phonology is between South Australia and the other states and territories. The trap–bath split is more complete in South Australia, in contrast to
8448-655: The vital support flow Qc in wet areas (white water) is larger than in semi-arid regions (heap slot). The proposed critical support flow (CSD) concept and model method can be used to determine the hydrographic indicators of river sources in complex geographical areas, and it can also reflect the impact of hydrologic climate change on river recharge in different regions. The source of a river or stream (its point of origin) can consist of lakes, swamps, springs, or glaciers. A typical river has several tributaries; each of these may be made up of several other smaller tributaries, so that together this stream and all its tributaries are called
8544-512: The water flows off the land as runoff, the proportion of which varies according to many factors, such as wind, humidity, vegetation, rock types, and relief. This runoff starts as a thin film called sheet wash, combined with a network of tiny rills, together constituting sheet runoff; when this water is concentrated in a channel, a stream has its birth. Some creeks may start from ponds or lakes. The streams typically derive most of their water from rain and snow precipitation. Most of this water re-enters
8640-417: The word bloody as a mild expletive or intensifier . "Mate" is also used in multiple ways including to indicate "mateship" or formally call out the target of a threat or insult, depending on internation and context. Several words used by Australians were at one time used in the UK but have since fallen out of usage or changed in meaning there. For example, creek in Australia, as in North America, means
8736-403: The word footy generally refers to the most popular football code in an area; that is, rugby league or rugby union depending on the local area, in most of New South Wales and Queensland. More commonly "rugby" is used to distinguish rugby union from "footy" which refers to the more popular rugby league. Footy commonly is used for Australian rules football elsewhere however the term refers to
8832-529: The word was contested in 2004 by Frederick Ludowyk of the Australian National Dictionary Centre , whose view was that that "-bong" or "-bang" was a suffix "signifying a continuation in time or space". Ludowyk writes that bong meaning "dead" is not a Wiradjuri word, but may have been picked up or assumed from the word "bung", which was originally a Yagara word used in the pidgin widely spoken across Australia. The word
8928-521: The year and is marked on topographic maps with a line of blue dashes and dots. A wash , desert wash, or arroyo is normally a dry streambed in the deserts of the American Southwest , which flows after sufficient rainfall. In Italy, an intermittent stream is termed a torrent ( Italian : torrente ). In full flood the stream may or may not be "torrential" in the dramatic sense of the word, but there will be one or more seasons in which
9024-402: The year. A stream of the first order is a stream which does not have any other recurring or perennial stream feeding into it. When two first-order streams come together, they form a second-order stream. When two second-order streams come together, they form a third-order stream. Streams of lower order joining a higher order stream do not change the order of the higher stream. The gradient of
9120-437: Was continued with the popularity of American films from the early 20th century and the influx of American military personnel during World War II ; seen in the enduring persistence of such universally-accepted terms as okay and guys . The publication of Edward Ellis Morris 's Austral English: A Dictionary Of Australasian Words, Phrases And Usages in 1898, which extensively catalogued Australian English vocabulary, started
9216-519: Was initially spread by young people in the 1960s. It found that the high rising terminal was used more than twice as often by young people than older people, and is more common among women than men. In the United Kingdom , it has occasionally been considered one of the variety's stereotypical features, and its spread there is attributed to the popularity of Australian soap operas . Australian English has many words and idioms which are unique to
