Shannon River (Western Australia)
Shannon River is a river located in the Great Southern region of Western Australia. The river rises in the forests to the west of Lake Muir and flows in a southerly direction, crossing the South Western Highway just east of Shannon then continuing south through the Shannon National Park before entering the Broke Inlet. The only tributary of the river is Fish Creek. The water quality of the river is excellent, fresh and low in sediment Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles. For example, sand an ...s. Sandbanks bar the mouth of the river where in enters the inlet. References Rivers of the Great Southern region Warren bioregion {{WesternAustralia-river-stub ...

Broke Inlet
Broke Inlet, originally named Broke's Inlet, is an inlet in the South West region of Western Australia located west of Walpole. The inlet is a large shallow estuary at the eastern end of the d'Entrecasteaux National Park, linked to the Southern Ocean by a narrow seasonally open channel situated between two high sand dune systems. The inlet is the only large estuary left in the South West that has not been significantly altered by development within its catchment area or along its shores. The catchment of the inlet has an area of and the inlet itself has a surface area of with a total volume of . The inlet receives an annual inflow of , mostly from the Shannon River and discharges annually. The water in the inlet is brackish and generally has half the salinity of sea water. The salinity varies greatly depending on river discharge, the season and whether the bar is open or not. Broke Inlet is listed as a regionally significant wetland with Environment Australia Envi ...

River
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as Stream#Creek, creek, Stream#Brook, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to Geographical feature, geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "Burn (landform), burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from Precipitation (meteorology), precipitation through a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Southern (Western Australia)
__NOTOC__ The Great Southern Region is one of the nine regions of Western Australia, as defined by the Regional Development Commissions Act 1993, for the purposes of economic development. It is a section of the larger South coast of Western Australia and neighbouring agricultural regions. The region officially comprises the local government areas of Albany, Broomehill-Tambellup, Cranbrook, Denmark, Gnowangerup, Jerramungup, Katanning, Kent, Kojonup, Plantagenet and Woodanilling. The Great Southern Region has an area of and a population of about 54,000. Its administrative centre is the historic port of Albany. It has a Mediterranean climate, with hot, dry summers and cool, wet winters. The Stirling Range is the only place in Western Australia that regularly receives snowfalls, if only very light. The economy of the Great Southern Region is dominated by livestock farming, dairy farming and crop-growing. It has some of the most productive cereal grain and pastoral l ...

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Muir
Lake Muir is a freshwater lake, with a larger surrounding wetlands area, that is located in the South West region of Western Australia. The lake lies near Muirs Highway, north of Walpole and southeast of Manjimup. Description The lake has a surface area of . Lake Muir and its surrounding wetland lies within the Lake Muir-Byenup System, a area of internal drainage containing a complex of wetland systems. Lake Muir may, in flood, overflow southwest into the Deep River catchment (and possibly also southeast into the Frankland River via Poorginup Gully). Lake Muir is usually brackish (1000–3000 mg/L TDS) at the end of winter, saline by summer and dry throughout autumn. Lake Muir is protected within Lake Muir Nature Reserve, which was designated in 2001. UNEP-WCMC (2022). Protected Area Profile for Lake Muir from the World Database of Protected Areas.

South Western Highway
South Western Highway is a highway in the South West region of Western Australia connecting Perth's southeast with Walpole. It is a part of the Highway 1 network for most of its length. It is about long. Route description Perth to Bunbury From Perth, the highway, signed as State Route 20, starts from the Albany Highway junction in Armadale, 28 km from Perth, and follows a north–south route 20–30 km inland from the coast, passing through several agricultural and timber towns that sprang up in the 1890s when the nearby railway came through, such as Pinjarra, Waroona, Yarloop and Harvey. In January 2016, the Samson Brook bridge, one of the highway bridges near Waroona, was damaged by a bushfire. Just past Brunswick Junction, the highway heads southwest towards Western Australia's third-largest city, Bunbury. The typical scenery on this part of the highway includes small dairy farms and orchards, jarrah and marri remnant forests and pine plantations. Unti ...

Shannon National Park
Shannon National Park is a national park on the south coast of Western Australia, south of Perth and southeast of Manjimup. It was declared a national park in 1988. The park covers the entire Shannon River basin. It is part of the larger Walpole Wilderness Area that was established in 2004, an international biodiversity hotspot. The area contains biologically rich wetlands and heathlands as well as old growth and regrowth karri forests. The area remained largely untouched by logging until the 1940s due to the inaccessibility of the area. A timber mill and the town of Shannon were established in the mid-1940s as a result of a timber shortage during World War II. The town once boasted over 90 homes and a hall, post office, church and nursing station. A dam was built in 1949 to guarantee water supply during the summer months. The mill eventually closed in 1968 and the houses were sold and moved leaving the townsite empty and a campground now stands were the town once did. The a ...

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 ...

Water Quality
Water quality refers to the chemical, physical, and biological characteristics of water based on the standards of its usage. It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed. The most common standards used to monitor and assess water quality convey the health of ecosystems, safety of human contact, extend of water pollution and condition of drinking water. Water quality has a significant impact on water supply and oftentimes determines supply options. Categories The parameters for water quality are determined by the intended use. Work in the area of water quality tends to be focused on water that is treated for potability, industrial/domestic use, or restoration (of an environment/ecosystem, generally for health of human/aquatic life). Human consumption Contaminants that may be in untreated water include microorganisms such as viruses, protozoa and bacteria; inorganic ...

Freshwater Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
