A floodplain or flood plain or bottomlands is an area of land adjacent to a river . Floodplains stretch from the banks of a river channel to the base of the enclosing valley, and experience flooding during periods of high discharge . The soils usually consist of clays, silts , sands, and gravels deposited during floods.
96-670: Sandgate Road is a major road in Brisbane , Queensland , Australia. It provides part of the road connection between Redcliffe and the Brisbane CBD . It is designated state route 26 throughout most of its length. The road is divided for the majority of its route, ranging from 4 to 6 lanes in some rare places with the majority of the road being 2 to 4 lanes. It also includes a tunneled section (the George Bridges Tunnel named after local pioneer George Bridges) underneath
192-884: A raid on the Queensland Government Printing Office , with the aim of confiscating copies of Hansard that covered debates in the Queensland Parliament where anti-conscription sentiments had been aired. Russian immigration took place in the years 1911–1914. Many were radicals and revolutionaries seeking asylum from tsarist political repression in the final chaotic years of the Russian Empire ; considerable numbers were Jews escaping state-inspired pogroms. They had fled Russia via Siberia and Northern China, most making their way to Harbin , in Manchuria , then taking passage from
288-532: A triumphal arch erected in Queen Street . In May that year, the Duke of Cornwall and York (later King George V ) laid the foundation stone of St John's Cathedral , one of the great cathedrals of Australia . The University of Queensland was founded in 1909 and first sited at Old Government House , which became vacated as the government planned for a larger residence. Fernberg House , built in 1865, became
384-589: A Turrbal culture organisation claims that historical documents suggest that the Turrbal peoples were the only traditional owners of Brisbane when British settlers first arrived. Archaeological evidence suggests frequent habitation around the Brisbane River, and notably at the site now known as Musgrave Park . The rivers were integral to life and supplied an abundance of food included fish, shellfish, crab, and prawns . Good fishing places became campsites and
480-498: A brick was thrown into the motel room and police took action to clear the road and consequently disproportionate violence was used against demonstrators. In the lead up to the 1980s Queensland fell subject to many forms of censorship. In 1977 things had escalated from prosecutions and book burnings, under the introduction of the Literature Board of Review, to a statewide ban on protests and street marches. In September 1977
576-407: A channel. Sediments from the crevasse spread out as delta -shaped deposits with numerous distributary channels. Crevasse formation is most common in sections of rivers where the river bed is accumulating sediments ( aggrading ). Repeated flooding eventually builds up an alluvial ridge, whose natural levees and abandoned meander loops may stand well above most of the floodplain. The alluvial ridge
672-598: A counterculture focused on the University of Queensland , street marches and Brisbane punk rock music. In 1971, the touring Springboks were to play against the Australian Rugby team. This was met with plans for protests due to the growing international and local opposition to apartheid in South Africa. However, before their arrival Bjelke-Petersen declared a state of emergency for a month, citing
768-626: A cry for "bread or blood", rioted and attempted to ransack the Government store . The City Botanic Gardens were originally established in 1825 as a farm for the Moreton Bay penal settlement , and were planted by convicts in 1825 with food crops to feed the prison colony. In 1855, several acres was declared a Botanic Reserve under the Superintendent Walter Hill , a position he held until 1881. Some trees planted in
864-658: A destination of interstate migration. Some of Brisbane's popular landmarks were lost to development in controversial circumstances, including the Bellevue Hotel in 1979 and Cloudland in 1982. Major public works included the Riverside Expressway , the Gateway Bridge , and later, the redevelopment of South Bank . Starting with the monumental Robin Gibson -designed Queensland Cultural Centre , with
960-554: A flood-prone property to qualify for government-subsidized insurance, a local community must adopt an ordinance that protects the floodway and requires that new residential structures built in Special Flood Hazard Areas be elevated to at least the level of the 100-year flood. Commercial structures can be elevated or floodproofed to or above this level. In some areas without detailed study information, structures may be required to be elevated to at least two feet above
1056-445: A floodplain. The quantity of sediments in a floodplain greatly exceeds the river load of sediments. Thus, floodplains are an important storage site for sediments during their transport from where they are generated to their ultimate depositional environment. When the rate at which the river is cutting downwards becomes great enough that overbank flows become infrequent, the river is said to have abandoned its floodplain. Portions of

Brisbane is located in the hilly floodplain of the Brisbane River Valley between Moreton Island and the Taylor and D'Aguilar mountain ranges . It sprawls across several local government areas , most centrally the City of Brisbane . The demonym of Brisbane is Brisbanite . The Moreton Bay penal settlement
1248-471: A permit. You won't get one. That's government policy now." In response to this, protesters came up with the idea of Phantom Civil Liberties Marches where protesters would gather and march until the police and media arrived. They would then disperse, and gather together again until the media and police returned, repeating the process over and over again. The end of the Bjelke-Petersen era began with
1344-467: A popular mode of public transport until the network was closed in 1969, in part the result of the Paddington tram depot fire . Between 1968 and 1987, Queensland was governed by Bjelke-Petersen, whose government was characterised by social conservatism , police corruption , and the brutal suppression of protest and has been described as a police state . However, during this time Brisbane developed
1440-447: A substantial settlement of brick and stone buildings, complete with school and hospital. He formed additional outstations and made several important journeys of exploration. Logan became infamous for his extreme use of the cat o' nine tails on convicts. The maximum allowed limit of lashes was 50; however, Logan regularly applied sentences of 150 lashes. During this period raids on maize fields were conducted by local Aboriginal groups in
1536-544: A tent and often landed ashore, thus bestowing upon the future Brisbane City the distinction of being the only Australian capital city visited by its namesake. Chief Justice Forbes gave the new settlement the name of Edenglassie before it was named Brisbane . The penal settlement under the control of Captain Patrick Logan (Commandant from 1826 to 1830) flourished, with the numbers of convicts increasing dramatically from around 200 to over 1,000 men. He developed
1632-611: Is a more accurate and appropriate Aboriginal name for Brisbane. Aboriginal groups claiming traditional ownership of the area include the Yagara , Turrbal and Quandamooka peoples. Brisbane is home to the land of a number of Aboriginal language groups, primarily the Yagara language group which includes the Turrbal language . The city is also known as Meanjin , a Turrbal word that originally referred to land on which parts of
1728-546: Is a problem in freshwater systems. Much of the phosphorus in freshwater systems comes from municipal wastewater treatment plants and agricultural runoff. Stream connectivity controls whether phosphorus cycling is mediated by floodplain sediments or by external processes. Under conditions of stream connectivity, phosphorus is better able to be cycled, and sediments and nutrients are more readily retained. Water in freshwater streams ends up in either short-term storage in plants or algae or long-term in sediments. Wet/dry cycling within
1824-406: Is advantageous for the rapid colonization of large areas of the floodplain. This allows them to take advantage of shifting floodplain geometry. For example, floodplain trees are fast-growing and tolerant of root disturbance. Opportunists (such as birds) are attracted to the rich food supply provided by the flood pulse. Floodplain ecosystems have distinct biozones. In Europe, as one moves away from
1920-498: Is any area subject to inundation by a 100-year flood. A problem is that any alteration of the watershed upstream of the point in question can potentially affect the ability of the watershed to handle water, and thus potentially affects the levels of the periodic floods. A large shopping center and parking lot, for example, may raise the levels of 5-year, 100-year, and other floods, but the maps are rarely adjusted and are frequently rendered obsolete by subsequent development. In order for
2016-565: Is largely a result of flood control, hydroelectric development (such as reservoirs), and conversion of floodplains to agriculture use. Transportation and waste disposal also have detrimental effects. The result is the fragmentation of these ecosystems, resulting in loss of populations and diversity and endangering the remaining fragments of the ecosystem. Flood control creates a sharper boundary between water and land than in undisturbed floodplains, reducing physical diversity. Floodplain forests protect waterways from erosion and pollution and reduce

Other major landmarks and precincts of the city include the Queensland Cultural Centre (including the Queensland Art Gallery , the Gallery of Modern Art ,
2304-463: Is the capital and largest city of the state of Queensland and the third-most populous city in Australia and Oceania , with a population over 2.7 million. Brisbane lies at the centre of South East Queensland , an urban agglomeration with a population of approximately 4 million which includes several other regional centres and cities. The central business district is situated within
2400-708: Is topped by a channel belt formed by successive generations of channel migration and meander cutoff. At much longer intervals, the river may abandon the channel belt and build a new one at another position on the floodplain. This process is called avulsion and occurs at intervals of 10–1000 years. Historical avulsions leading to catastrophic flooding include the 1855 Yellow River flood and the 2008 Kosi River flood . Floodplains can form around rivers of any kind or size. Even relatively straight stretches of river are capable of producing floodplains. Mid-channel bars in braided rivers migrate downstream through processes resembling those in point bars of meandering rivers and can build up
2496-557: The 2032 Summer Olympics and 2032 Summer Paralympics . Floodplain Because of regular flooding, floodplains frequently have high soil-fertility since nutrients are deposited with the flood waters. This can encourage farming ; some important agricultural regions, such as the Nile and Mississippi river basins , heavily exploit floodplains. Agricultural and urban regions have developed near or on floodplains to take advantage of
2592-659: The Brisbane City Council . A significant year for Brisbane was 1930, with the completion of Brisbane City Hall , then the city's tallest building and the Shrine of Remembrance , in ANZAC Square , which has become Brisbane's main war memorial. These historic buildings, along with the Story Bridge which opened in 1940, are key landmarks that help define the architectural character of the city. Following

The name is derived from the Scottish Gaelic bris , meaning ' to break or smash ' and
2784-637: The Corn Field Raids of 1827-1828 . These groups destroyed and plundered the maize fields in South Bank and Kangaroo Point , with the possible motive of extracting compensation from the settlers or warning them not to expand beyond their current area. Between 1824 and 1842, almost 2,400 men and 145 women were detained at the Moreton Bay convict settlement under the control of military commandants. However, non-convict European settlement of

3552-725: The Queensland Parliament built in 1867. The 1880s brought a period of economic prosperity and a major construction boom in Brisbane, that produced an impressive number of notable public and commercial buildings. John James Clark was appointed Queensland Government Architect in 1883, and continuing in Tiffin's design for public buildings, asserted the propriety of the Italian Renaissance, drawing upon typological elements and details from conservative High Renaissance sources. Building in this trace of intellectualism, Clark designed

The most notable incident occurred on 24 March 1919, when a crowd of about 8,000 ex-servicemen clashed violently with police who were preventing them from attacking the Russian Hall in Merivale Street, South Brisbane , which was known as the Battle of Merivale Street. Over 20 small municipalities and shires were amalgamated in 1925 to form the City of Brisbane, governed by
3744-723: The Treasury Building in 1886, and the Yungaba Immigration Centre in 1885. Other major works of the era include Customs House in 1889, and the Old Museum Building completed in 1891. Fort Lytton was constructed in 1882 at the mouth of the Brisbane river, to protect the city against foreign colonial powers such as Russia and France , and was the only moated fort ever built in Australia. The city's slum district of Frog's Hollow , named so for its location being low-lying and swampy,

4032-563: The Brisbane region commenced in 1838 and the population grew strongly thereafter, with free settlers soon far outstripping the convict population. German missionaries settled at Zions Hill, Nundah as early as 1837, five years before Brisbane was officially declared a free settlement. The band consisted of ministers Christopher Eipper (1813–1894), Carl Wilhelm Schmidt , and lay missionaries Haussmann, Johann Gottried Wagner, Niquet, Hartenstein, Zillman, Franz, Rode, Doege and Schneider. They were allocated 260 hectares and set about establishing

Charles Tiffin was appointed as Queensland Government Architect in 1859, and pursued an intellectual policy in the design of public buildings based on Italianate and Renaissance revivalism , with such buildings as Government House , the Department of Primary Industries Building in 1866, and
4320-560: The NFIP as the Special Flood Hazard Area. Where a detailed study of a waterway has been done, the 100-year floodplain will also include the floodway, the critical portion of the floodplain which includes the stream channel and any adjacent areas that must be kept free of encroachments that might block flood flows or restrict storage of flood waters. Another commonly encountered term is the Special Flood Hazard Area, which

The Brisbane River did not reach the same height as the previous 1974 flood on either occasion, but caused extensive disruption and damage to infrastructure. The Queensland Cultural Centre was also expanded, with the completion of the State Library and
4608-400: The abandoned floodplain may be preserved as fluvial terraces . Floodplains support diverse and productive ecosystems . They are characterized by considerable variability in space and time, which in turn produces some of the most species-rich of ecosystems. From the ecological perspective, the most distinctive aspect of floodplains is the flood pulse associated with annual floods, and so

These extreme weather events cause severe economic disruption and loss of human life in the densely-populated region. Floodplain soil composition is unique and varies widely based on microtopography. Floodplain forests have high topographic heterogeneity which creates variation in localized hydrologic conditions. Soil moisture within

Brisbane will host
6144-448: The floodplain ecosystem is defined as the part of the river valley that is regularly flooded and dried. Floods bring in detrital material rich in nutrients and release nutrients from dry soil as it is flooded. The decomposition of terrestrial plants submerged by the floodwaters adds to the nutrient supply. The flooded littoral zone of the river (the zone closest to the river bank) provides an ideal environment for many aquatic species, so
6240-462: The floodplain has a big impact on phosphorus availability because it alters water level, redox state, pH, and physical properties of minerals. Dry soils that were previously inundated have reduced availability of phosphorus and increased affinity for obtaining phosphorus. Human floodplain alterations also impact the phosphorus cycle. Particulate phosphorus and soluble reactive phosphorus (SRP) can contribute to algal blooms and toxicity in waterways when

6624-465: The impact of floodwaters. The disturbance by humans of temperate floodplain ecosystems frustrates attempts to understand their natural behavior. Tropical rivers are less impacted by humans and provide models for temperate floodplain ecosystems, which are thought to share many of their ecological attributes. Excluding famines and epidemics , some of the worst natural disasters in history (measured by fatalities) have been river floods, particularly in

This did not stop the protest however with violent clashes between protestors and police erupting when several hundred demonstrators assembled outside a Brisbane motel on Thursday, 22 July 1971, where the Springbok team was staying. A second protest saw a large number of demonstrators assembled once more outside the Tower Mill Motel and after 15 minutes of peaceful protest,
6816-617: The makeup towards ash (49%) with maple increasing to 14% and oak decreasing to 25%. Semiarid floodplains have a much lower species diversity. Species are adapted to alternating drought and flood. Extreme drying can destroy the ability of the floodplain ecosystem to shift to a healthy wet phase when flooded. Floodplain forests constituted 1% of the landscape of Europe in the 1800s. Much of this has been cleared by human activity, though floodplain forests have been impacted less than other kinds of forests. This makes them important refugia for biodiversity. Human destruction of floodplain ecosystems
6912-498: The meander cuts into higher ground. The overall effect is that, as the river meanders, it creates a level flood plain composed mostly of point bar deposits. The rate at which the channel shifts varies greatly, with reported rates ranging from too slow to measure to as much as 2,400 feet (730 m) per year for the Kosi River of India. Overbank flow takes place when the river is flooded with more water than can be accommodated by
7008-448: The meander. This is described as lateral accretion since the deposition builds the point bar laterally into the river channel. Erosion on the outside of the meander usually closely balances deposition on the inside so that the channel shifts in the direction of the meander without changing significantly in width. The point bar is built up to a level very close to that of the river banks. Significant net erosion of sediments occurs only when

7296-538: The new colony, reporting that ships could land at any tide and easily get close to the shore. The convict settlement party landed in Redcliffe on 13 September 1824 formally establishing the Moreton Bay Penal Settlement that would become Brisbane. The party was under the command of Lieutenant Henry Miller and consisted of 14 soldiers (some with wives and children) and 29 convicts. However,
7392-762: The nitrogen-to-phosphorus ratios are altered farther upstream. In areas where the phosphorus load is primarily particulate phosphorus, like the Mississippi River, the most effective ways of removing phosphorus upstream are sedimentation, soil accretion, and burial. In basins where SRP is the primary form of phosphorus, biological uptake in floodplain forests is the best way of removing nutrients. Phosphorus can transform between SRP and particulate phosphorus depending on ambient conditions or processes like decomposition, biological uptake, redoximorphic release, and sedimentation and accretion. In either phosphorus form, floodplain forests are beneficial as phosphorus sinks, and
7488-442: The overbank flow. Most of the suspended sand is deposited on the levees, leaving the silt and clay sediments to be deposited as floodplain mud further from the river. Levees are typically built up enough to be relatively well-drained compared with nearby wetlands, and levees in non-arid climates are often heavily vegetated. Crevasses are formed by breakout events from the main river channel. The river bank fails, and floodwaters scour
7584-563: The port of Dalian to Townsville or Brisbane, the first Australian ports of call. Following the First World War , conflict arose between returned servicemen of the First Australian Imperial Force and socialists along with other elements of society that the ex-servicemen considered to be disloyal toward Australia. Over the course of 1918–1919, a series of violent demonstrations and attacks known as
7680-405: The rich soil and freshwater. However, the risk of inundation has led to increasing efforts to control flooding . Most floodplains are formed by deposition on the inside of river meanders and by overbank flow. Wherever the river meanders, the flowing water erodes the river bank on the outside of the meander. At the same time, sediments are simultaneously deposited in a bar on the inside of
7776-400: The river channel. Flow over the banks of the river deposits a thin veneer of sediments that is coarsest and thickest close to the channel. This is described as vertical accretion , since the deposits build upwards. In undisturbed river systems, overbank flow is frequent, typically occurring every one to two years, regardless of climate or topography. Sedimentation rates for a three-day flood of
7872-511: The river, the successive plant communities are bank vegetation (usually annuals); sedge and reeds; willow shrubs; willow-poplar forest; oak-ash forest; and broadleaf forest. Human disturbance creates wet meadows that replace much of the original ecosystem. The biozones reflect a soil moisture and oxygen gradient that in turn corresponds to a flooding frequency gradient. The primeval floodplain forests of Europe were dominated by oak (60%) elm (20%) and hornbeam (13%), but human disturbance has shifted
7968-561: The route of Sandgate Road through Nundah in the 1860s refer to Nundah growth . The following timeline shows events that were pertinent to the development of Sandgate Road. Before the construction of Stage 3 of the Inner City Bypass in 2002 the southern end of Sandgate Road was at the point where Breakfast Creek Road crosses Breakfast Creek. Prior to the construction of the Abbotsford Road Bridge in 1928 this
8064-399: The same year, with the city receiving more than a year's rainfall during February 1893, leaving much of the city's population homeless. In 1896, the Brisbane river saw its worst maritime disaster with the capsize of the ferry Pearl , between the 80–100 people on board there were only 40 survivors. When the colonies federated in 1901, celebrations were held in Brisbane to mark the event, with
8160-501: The settlers abandoned this site after a year and moved to an area on the Brisbane River now known as North Quay, 28 km (17 mi) south, which offered a more reliable water-supply. The newly selected Brisbane region was plagued by mosquitoes at the time. After visiting the Redcliffe settlement, Sir Thomas Brisbane then travelled 45 km (28 mi) up the Brisbane River in December 1824. Governor Brisbane stayed overnight in
8256-470: The ship Fortitude arrived in Brisbane in 1849, enticed by Lang on the promise of free land grants. Denied land, the immigrants set up camp in York's Hollow waterholes in the vicinity of today's Victoria Park , Herston , Queensland. A number of the immigrants moved in and settled the suburb, naming it Fortitude Valley after the ship on which they arrived. Free settlers entered the area from 1835, and by
8352-408: The spawning season for fish often coincides with the onset of flooding. Fish must grow quickly during the flood to survive the subsequent drop in water level. As the floodwaters recede, the littoral experiences blooms of microorganisms, while the banks of the river dry out and terrestrial plants germinate to stabilize the bank. The biota of floodplains has high annual growth and mortality rates, which
8448-691: The state separated from New South Wales . By the late 19th century, the city had grown into a major port and centre of immigration. During World War II , the Allied command in the South West Pacific was based in the city, along with the headquarters for General Douglas MacArthur of the United States Army. Brisbane is a global centre for research and innovation and is a transportation hub, being served by large rail , bus and ferry networks, as well as Brisbane Airport and
8544-459: The surrounding grade. Many State and local governments have, in addition, adopted floodplain construction regulations which are more restrictive than those mandated by the NFIP. The US government also sponsors flood hazard mitigation efforts to reduce flood impacts. California 's Hazard Mitigation Program is one funding source for mitigation projects. A number of whole towns such as English, Indiana , have been completely relocated to remove them from
8640-513: The temporary residence in 1910, and later made the permanent government house. In 1912, Tramway employees were stood down for wearing union badges which sparked Australia's first general strike , the 1912 Brisbane General Strike , which became known as Black Friday, for the savagery of the police baton charges on crowds of trade unionists and their supporters. In 1917, during World War I , the Commonwealth Government conducted
8736-529: The town centre of Nundah. It also passes The now closed Demolised Toombul Shopping Centre opposite Toombul station According to surveys by the RACQ , Sandgate Road is one of the states 10 most frustrating roads. At Clayfield , the road crosses the Doomben railway line via an overpass . European settlement occurred along what is now Sandgate Road from as early as 1838 (see Nundah history for an example) but
8832-672: The upper 30 cm of the soil profile also varies widely based on microtopography which affects oxygen availability. Floodplain soil stays aerated for long stretches of time in between flooding events, but during flooding, saturated soil can become oxygen-depleted if it stands stagnant for long enough. More soil oxygen is available at higher elevations farther from the river. Floodplain forests generally experience alternating periods of aerobic and anaerobic soil microbe activity which affects fine root development and desiccation. Floodplains have high buffering capacity for phosphorus to prevent nutrient loss to river outputs. Phosphorus nutrient loading
8928-594: Was both the red light district of colonial Brisbane and its Chinatown , and was the site of prostitution , sly grog , and opium dens . In 1888, Frog's Hollow was the site of anti-Chinese riots, where more than 2000 people attacked Chinese homes and businesses. In 1893 Brisbane was affected by the Black February flood , when the Brisbane River burst its banks on three occasions in February and again in June in
9024-467: Was founded in 1824 at Redcliffe as a place for secondary offenders from the Sydney colony , and soon moved to North Quay in 1825 on the banks of the Brisbane River, so named for British army general and Governor of New South Wales Sir Thomas Brisbane . German Lutherans established the first free settlement of Zion Hill at Nundah in 1838, and in 1859 Brisbane was chosen as Queensland's capital when
9120-545: Was the only direct access to Sandgate Road from the Brisbane CBD . A project to upgrade the intersection with Cameron Street, at a cost of $ 1.336 million, was to start in August 2022. A project to upgrade the intersection with Northgate Road, at a cost of $ 1.296 million, was to start in August 2022. The entire road is in the Brisbane local government area. Brisbane Brisbane ( / ˈ b r ɪ z b ən / BRIZ -bən , Turrbal : Meanjin )
9216-513: Was the site of a violent clash between visiting US military personnel and Australian servicemen and civilians, which resulted in one death and hundreds of injuries. This incident became known colloquially as the Battle of Brisbane . Post-war Brisbane had developed a big country town stigma, an image the city's politicians and marketers were very keen to remove. In the late 1950s, an anonymous poet known as The Brisbane Bard generated much attention to
