Dale River (Western Australia)
The Dale River is a perennial river located in the Wheatbelt region of Western Australia. Rising on the eastern slopes of the Darling Scarp, the river flow generally east by north, joined by six major tributaries including the Dale River South, Gibb Gully, Connelly Gully, Sherlock Gully, Flint Gully and Talbot Brook. The river reaches its mouth to join the Avon River approximately west of near the Avondale Agricultural Research Station. The river descends over its course. The Dale River was named in honour of Robert Dale Lieutenant Robert Dale (1810–20 July 1853) was the first European explorer to cross the Darling Range in Western Australia.

Robert Dale
Lieutenant Robert Dale (1810–20 July 1853) was the first European explorer to cross the Darling Range in Western Australia. Robert Dale was born in Winchester, England in November 1810, son of Major Thurston Dale and Helen Matthews. Through the influence of his great-uncle General William Dyott, on 25 October 1827 he was appointed an ensign in the British Army's 63rd Regiment of Foot. In February 1829 Dale embarked for Western Australia on as part of a detachment of troops commanded by Captain Frederick Chidley Irwin. On arrival at the colony, he was seconded as an assistant to Surveyor General John Septimus Roe, whose Survey Department was suffering under an extreme workload. Dale spent four years with the Survey Department, surveying, clearing roads and exploring. He was the first European to cross the Darling Range, where he discovered the fertile Avon Valley and explored the future locations of Northam, Toodyay and York. He was also the first European to see and de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wheatbelt (Western Australia)
The Wheatbelt is one of nine regions of Western Australia defined as administrative areas for the state's regional development, and a vernacular term for the area converted to agriculture during colonisation. It partially surrounds the Perth metropolitan area, extending north from Perth to the Mid West region, and east to the Goldfields–Esperance region. It is bordered to the south by the South West and Great Southern regions, and to the west by the Indian Ocean, the Perth metropolitan area, and the Peel region. Altogether, it has an area of (including islands). The region has 42 local government authorities, with an estimated population of 75,000 residents. The Wheatbelt accounts for approximately three per cent of Western Australia's population. Ecosystems The area, once a diverse ecosystem, reduced when clearing began in the 1890s with the removal of plant species such as eucalypt woodlands and mallee, is now home to around 11% of Australia's critically end ...

Darling Scarp
The Darling Scarp, also referred to as the Darling Range or Darling Ranges, is a low escarpment running north–south to the east of the Swan Coastal Plain and Perth, Western Australia. The escarpment extends generally north of Bindoon, to the south of Pemberton. The adjacent Darling Plateau goes easterly to include Mount Bakewell near York and Mount Saddleback near Boddington. It was named after the Governor of New South Wales, Lieutenant-General Ralph Darling. History The feature was first recorded as General Darling Range by Charles Fraser, Government Botanist with Captain James Stirling aboard in March 1827. Maps from the 1830s show the scarp labelled " General Darlings Range"; this later became Darling Range, a name by which the formation was still commonly known in the late 20th century despite common understanding of it being an escarpment. There is also a tendency to identify the locations on or to the east of the scarp as being in the "Perth Hills" (or simpl ...

Avon River (Western Australia)
The Avon River is a river in Western Australia. A tributary of the Swan River, the Avon flows from source to mouth, with a catchment area of . Avon catchment area Lake Yealering in the Shire of Wickepin is the point of origin for the upper Avon River, and the catchment size above the confluence with the Salt River at Yenyening Lakes is . The basin covers much of the West Australian wheatbelt and extends beyond that in some areas near almost-always-dry Lake Moore in the northeast, water is received regularly from only the extreme western edge of the basin. Indeed, until an abnormally wet year in 1963 it was not realised that the northeastern part of the basin beyond Wongan Hills ever drained water into the river. Under present climatic conditions, it is almost impossible to produce runoff from anywhere outside the extreme west of the basin because the amount of rain required to fall before runoff would begin is as high or higher than the mean annual rainfall. The river has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial River
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] |

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.

Avondale Agricultural Research Station
Avondale Agricultural Research Station or Avondale Discovery Farm is one of thirteen research farms and stations operated by Western Australia's Department of Agriculture and Food. In addition to its research, Avondale has historical buildings, a farming equipment museum and operates as an agriculture education centre specialising in introducing primary school children to farming, and teaching of its history in Western Australia. Avondale is situated on land where the Dale River joins the Avon River northwest of Beverley. It is located on land originally granted to the first Governor of Western Australia, Captain (later Admiral Sir) James Stirling and Captain Mark Currie RN in 1836. These grants were combined in 1849 and with additional land purchases they became known as Avondale Estate, expanding to in excess of . On 4 April 1924 the remaining of Avondale were passed on to the Department of Agriculture and Food. Initially Avondale continued its involvement with the Gro ...

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] |
