Lerderderg River
The Lerderderg River (known locally as ''The Lerdy'') is a perennial river of the Port Phillip catchment, located in the Western District region of the Australian state of Victoria. Location and features The Lerderderg River rises below the Blackwood Ranges, part of the Great Dividing Range, in the Lerderderg State Forest, near the locality of . The river flows generally south by east in a highly meandering course, through the Lerderderg Gorge within the Wombat State Forest where it is joined by two minor tributaries, The Old River and Goodman Creek, before reaching its confluence with the Werribee River within the Melton Reservoir, southeast of Bacchus Marsh. The river descends approximately over its course. A diversion in the river's course, called the Lerderderg River diversion tunnel, located approximately upriver from Bacchus Marsh, was constructed between 1855 and 1870. The tunnel was driven through a mountain spur in a horseshoe bend, diverting the river, and allowin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mouth (river)
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.

Goodman Creek
Goodman Creek is a stream in the U.S. state of Washington. Goodman Creek bears the name of a government surveyor. It has also been known by the name Tsa-dis-qualth, meaning "narrow mouth overhung with bush". In one late 19th century publication it was also referred to as the Keh-chen-whilt River.

Drought In Australia
Drought in Australia is defined by the Australian Bureau of Meteorology as rainfall over a three-month period being in the lowest decile of what has been recorded for that region in the past. This definition takes into account that drought is a relative term and rainfall deficiencies need to be compared to typical rainfall patterns including seasonal variations. Specifically, drought in Australia is defined in relation to a rainfall deficiency of pastoral leases and is determined by decile analysis applied to a certain area. Note that this definition uses rainfall only because long-term records are widely available across most of Australia. However, it does not take into account other variables that might be important for establishing surface water balance, such as evaporation and condensation. Historical climatic records are now sufficiently reliable to profile climate variability taking into account expectations for regions. Bureau of Meteorology records since the 1860s show t ...

Sluice
Sluice ( ) is a word for a channel controlled at its head by a movable gate which is called a sluice gate. A sluice gate is traditionally a wood or metal barrier sliding in grooves that are set in the sides of the waterway and can be considered as a bottom opening in a wall. Sluice gates are one of the most common hydraulic structures in controlling flow rate and water level in open channels such as rivers and canals. They also could be used to measure the flow. A water channel containing a sluice gate forms a type of lock to manage the water flow and water level. It can also be an open channel which processes material, such as a River Sluice used in gold prospecting or fossicking. A mill race, leet, flume, penstock or lade is a sluice channeling water toward a water mill. The terms sluice, sluice gate, knife gate, and slide gate are used interchangeably in the water and wastewater control industry. They are also used in wastewater treatment plants and to recover minerals in minin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parks Victoria
Parks Victoria is a government agency of the state of Victoria, Australia. Parks Victoria was established in December 1996 as a statutory authority, reporting to the Victorian Minister for Environment and Climate Change. The ''Parks Victoria Act 2018'' updates the previous act, ''Parks Victoria Act 1998''. Under the new ''Act'' Parks Victoria is responsible for managing over '...4 million hectares including 3,000 land and marine parks and reserves making up 18 per cent of Victoria’s landmass, 75 per cent of Victoria’s wetlands and 70 per cent of Victoria’s coastline'. History Parks Victoria replaced many of the functions and absorbed the staff of the then Department of Natural Resources and Environment (which managed National and State parks) and Melbourne Parks & Waterways, which itself was originally part of the former Melbourne and Metropolitan Board of Works, which mostly managed urban parklands, some of which were formerly MMBW facilities, such as Braeside Park.

Spur (topography)
A spur is a lateral ridge or tongue of land descending from a hill, mountain or main crest of a ridge. It can also be defined as another hill or mountain range which projects in a lateral direction from a main hill or mountain range. Examples of spurs include: *Abbott Spur, which separates the lower ends of Rutgers Glacier and Allison Glacier on the west side of the Royal Society Range in Victoria Land, Antarctica *Boott Spur, a subpeak of Mount Washington *Kaweah Peaks Ridge, a spur of the Great Western Divide, a sub-range of California's Sierra Nevada *Kelley Spur, east of Spear Spur on the south side of Dufek Massif in the Pensacola Mountains, Antarctica *Geneva Spur on Mount Everest *Sperrin Mountains in Northern Ireland [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lerderderg River Diversion Tunnel
The Lerderderg River diversion tunnel, known as The Tunnel, is located on the Lerderderg River approximately 25 km north-west of Bacchus Marsh, Victoria, Australia. The river flows around a spur in a horseshoe bend. The tunnel was driven through the spur diverting the river and allowing the exposed river bed to be sluiced for alluvial gold. The tunnel was dug during the Victorian gold rush, most likely between 1855 and 1870, and is one of around thirteen river diversions surviving from that era. The site is within the Lerderderg State Park. It is a 3.0 km walk along Byers Track upstream from the O'Briens Crossing Picnic Area.

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 Pidwirny & S ...

Wombat State Forest
The Wombat State Forest (locally: Bullarook) is located west of Melbourne, Victoria, Australia, between Woodend and Daylesford, at the Great Dividing Range. The forest is approximately in size and sits upon Ordovician or Cenozoic sediments. The Bullarook Wombat State Forest was proclaimed in 1871. The only initiative in Australia to introduce community forestry, within the internationally understood context, is in the Wombat State Forest. It is managed by the Department of Environment, Land, Water and Planning. The management plan covers several areas such as firewood and other products; protection of water supplies; conservation of biodiversity; and conservation of landscape. Other areas of importance include cultural heritage, research, education, tourism, recreation, mineral exploration, mining, and grazing. On 24 June 2021, the Andrews State Government, following extensive review and recommendation, declerated that the Wombat State Forest would be added to the National ...

Lerderderg Gorge
The Lerderderg Gorge is in Victoria, Australia and largely within the Lerderderg State Park. The Lerderderg River which emerges from the Great Dividing Range has cut a deep gorge as it winds toward the southern plains. It is suggested that the name Lerderderg is perhaps a corruption of the Wurundjeri word "Larderdark," from 'larh' -stone house and 'dark' -peppermint gum. Location 37°37'35"S x 144°25'44"E to 37°23'42"S x 144°19'06"E Gorge of Lerderderg River extending from Nolan Gully south to the Lerderderg ford. Description Lerderderg State Park and the surrounding Wombat State Forest are north of Bacchus Marsh, around one hour's drive (90 km) (56 miles) from Melbourne on the Western Highway. Its myriad tracks, gullies creeks and ridges form a wild, rugged environment enjoyed by bushwalkers, horse riders and mountain bikers. The striking feature of this area is the 300-metre (975 feet) deep gorge that stretches south to the plains of Bacchus Marsh. Parts of the Wo ...

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 groundwater ... [...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 intermittent river, 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 damming, 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 (stream pool, pools and puddle, waterholes), reservoirs, oxbow lake, 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.
