Bungil Creek
The Bungil Creek, part of the Balonne catchment within the Murray-Darling basin, is a perennial stream located in South West Queensland, Australia. Course and features The headwaters of the creek rise on the south-western slopes of the Great Dividing Range, below Bymount and north of . The creek flows southeast through the town of Roma, with the Carnarvon Highway following much of the course of the creek. North of , the Bungil Creek reaches its confluence with the Spring Creek, a tributary of the Balonne River. The flow of the creek varies significantly from a very small trickle to a raging river after heavy rain. The creek descends over its course; with a catchment area of . The creek floods regularly, once inundating hundreds of properties in Roma. In March 2010, Bungil Creek experienced a major flood of ; with a peak flood height of in April 2011. Government funding enabled the construction of a levee for flood mitigation after devastating flooding in 2012. A ceremo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Mouth
A river mouth is where a river flows into a larger body of water, such as another river, a lake/reservoir, a bay/gulf, a sea, or an ocean. At the river mouth, sediments are often deposited due to the slowing of the current reducing the carrying capacity of the water. The water from a river can enter the receiving body in a variety of different ways. The motion of a river is influenced by the relative density of the river compared to the receiving water, the rotation of the earth, and any ambient motion in the receiving water, such as tides or seiches. If the river water has a higher density than the surface of the receiving water, the river water will plunge below the surface. The river water will then either form an underflow or an interflow within the lake. However, if the river water is lighter than the receiving water, as is typically the case when fresh river water flows into the sea, the river water will float along the surface of the receiving water as an overflow.

Carnarvon Highway
Carnarvon Highway is a state highway in Queensland and New South Wales, Australia, linking the township of Rolleston in Queensland's Central Highlands Region, via the town of St George, eventually to Moree in northern New South Wales. It is the main access road to the Carnarvon National Park, and serves as a strategic route to take B-doubles and other large vehicles (which cannot use the Bruce Highway) to the Queensland ports north of Rockhampton. Route Carnarvon Highway starts at the intersection with Dawson Highway just west of Rolleston in Queensland, and heads in southerly direction until it reaches Roma, where it shares a short concurrency with Warrego Highway, and continues south to St George, where it meets Moonie, Balonne, and Castlereagh Highways. It crosses the state border at Mungindi to eventually terminate at the town of Moree, in New South Wales. History The passing of the ''Main Roads (Amendment) Act of 1929'' (which amended the original ''Main Roads Act of 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Rivers Of Australia
This is a list of rivers of Australia. Rivers are ordered alphabetically, by state. The same river may be found in more than one state as many rivers cross state borders. Longest rivers nationally Longest river by state or territory Although the Murray River forms much of the border separating New South Wales and Victoria, it is not Victoria's longest river because the New South Wales border is delineated by the river's southern bank rather than by the middle of the river. The only section of the river formally within Victoria is a stretch of approximately where it separates Victoria and South Australia. At this point, the middle of the river forms the border. Rivers by state or territory The following is a list of rivers located within Australian states and territories. Where a river crosses a state or territory boundary, it is listed in both states and territories. Where a river has a name that includes the word creek, it has been officially designated as a river.

Flood Mitigation
In environmental engineering, the flood mitigation involves the management and control of flood water movement, such as redirecting flood run-off through the use of floodwalls and flood gates, rather than trying to prevent floods altogether. It also involves the management of people, through measures such as evacuation and dry/wet proofing properties. The prevention and mitigation of flooding can be studied on three levels: on individual properties, small communities, and whole towns or cities. The costs of protection rise as more people and property are protected. The US FEMA, for example, estimates that for every $1.00 spent on mitigation, $4.00 is saved. Protection of individual properties Property owners may fit their homes to stop water entering by blocking doors and air vents, waterproofing important areas and sandbagging the edges of the building. Flood mitigation at the property level may also involve preventative measures focused on the building site, including scour p ...

Levee
A levee (), dike (American English), dyke (Commonwealth English), embankment, floodbank, or stop bank is a structure that is usually earthen and that often runs parallel to the course of a river in its floodplain or along low-lying coastlines. The purpose of a levee is to keep the course of rivers from changing and to protect against flooding of the area adjoining the river or coast. Levees can be naturally occurring ridge structures that form next to the bank of a river, or be an artificially constructed fill or wall that regulates water levels. Ancient civilizations in the Indus Valley, ancient Egypt, Mesopotamia and China all built levees. Today, levees can be found around the world, and failures of levees due to erosion or other causes can be major disasters. Etymology Speakers of American English (notably in the Midwest and Deep South) use the word ''levee'', from the French word (from the feminine past participle of the French verb , 'to raise'). It originat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flood
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting ...

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are simi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tributary
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwir ...

Watercourse
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. The flow of 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 the water cycle, instruments in groundwate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial Stream
A perennial stream is a stream that has continuous flow of surface water throughout the year in at least parts of its catchment during seasons of normal rainfall, Water Supply Paper 494. as opposed to one whose flow is intermittent. In the absence of irregular, prolonged or extreme drought, a perennial stream is a watercourse, or segment, element or emerging body of water which continually delivers groundwater. For example, an artificial disruption of stream, variability in flow or stream selection associated with the activity in hydropower installations, do not affect this status. Perennial streams do not include stagnant water ( pools and waterholes), reservoirs, cutoff lakes and ponds that persist throughout the year. All other streams, or parts of them, should be considered seasonal rivers or lakes. The stream can cycle from intermittent to perpetual through multiple iterations. Stream Definition The basic concept means flowing bodies of water. In hydrology, the strea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
