Hay River (Western Australia)
The Hay River is a river in the Great Southern region of Western Australia. The traditional owners of the area are the Noongar people, who know the river as Genulup. The river was given its English name in December 1829 by naval ship's surgeon Thomas Braidwood Wilson after Sir Robert William Hay, Permanent Under-secretary of State for the Colonies from 1825 to 1836. Wilson saw the river while exploring the area in company with the native Mokare, John Kent (officer in charge of the Commissariat at King George Sound), two convicts and Private William Gough of the 39th Regiment, while his ship was being repaired at King George Sound. The Hay River is part of the Denmark catchment, which comprises Wilson Inlet, Torbay Inlet and Lake Powell, together with the catchments of the Denmark, Hay and Sleeman-Cuppup Rivers and their tributaries. The river rises west of Mount Barker near Wilpuna Park and flows south east as far as Ungerup then flows in a south-south-westerly direction t ...

Mount Barker, Western Australia
Mount Barker is a town on Albany Highway and the administrative centre of the Shire of Plantagenet in the Great Southern region of Western Australia. At the 2021 census, Mount Barker had a population of 2,855. The town was named after the nearby hill, which in turn was named in 1829 by Thomas Braidwood Wilson in honour of Captain Collet Barker, who was in command of Western Australia's original British settlement at King George's Sound from 1829 to 1831. __TOC__ Location Mount Barker is situated on Albany Highway, southeast of Perth and north of the city of Albany. The coastal town of Denmark is around by road to the southwest via the Denmark to Mount Barker Road. The timber town of Manjimup is west of Mount Barker, via Muirs Highway. The Hay River, which flows into Wilson Inlet at Denmark, begins its journey just west of Mount Barker. History Prior to European settlement, small groups of Aboriginal people, called the Bibbulmun (a clan of the Noongar) People, inh ...

Torbay Inlet
Torbay Inlet is an estuarine inlet in the Great Southern region of Western Australia situated approximately east of the town of Denmark, Western Australia. Torbay Inlet is a wave-dominated estuary that functions primarily as a result of wave energy. The estuary has been severely modified as most of the natural catchment cover has been cleared. Covering a total surface area of , of this is the central basin with the remainder being composed of saltmarsh and tidal delta. The lagoon is quite shallow and fringed with sedges and paperbarks. The inlet outflows into the Southern Ocean and is part of the Torbay Inlet and Lake Powell Catchment Area. Much of the land surrounding the inlet has an elevation of less than so that under certain tidal and wind conditions the land is inundated with sea water that floods back up the estuary. As a result, in 1912, a barrage with floodgates was constructed to prevent this, but this proved to be unsuccessful. A sandbar exists across the mouth ...

Riparian
A riparian zone or riparian area is the interface between land and a river or stream. Riparian is also the proper nomenclature for one of the terrestrial biomes of the Earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by hydrophilic plants. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on fauna and aquatic ecosystems, including grasslands, woodlands, wetlands, or even non-vegetative areas. In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone. The word ''riparian'' is derived from Latin '' ripa'', meaning " river bank". Characteristics Riparian zones may be natural or engineered for soil stabilization or restoration. These zones are important natural b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brackish
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root '' brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific grav ...

Saline Water
Saline water (more commonly known as salt water) is water that contains a high concentration of dissolved salts (mainly sodium chloride). On the United States Geological Survey (USGS) salinity scale, saline water is saltier than brackish water, but less salty than brine. The salt concentration is usually expressed in parts per thousand (permille, ‰) and parts per million (ppm). The USGS salinity scale defines three levels of saline water. The salt concentration in slightly saline water is 1,000 to 3,000 ppm (0.1–0.3%); in moderately saline water is 3,000 to 10,000 ppm (0.3–1%); and in highly saline water is 10,000 to 35,000 ppm (1–3.5%). Seawater has a salinity of roughly 35,000 ppm, equivalent to 35 grams of salt per one liter (or kilogram) of water. The saturation level is only nominally dependent on the temperature of the water. At one liter of water can dissolve about 357 grams of salt, a concentration of 26.3% w/w. At boiling () the amount that can be dissolved in o ...

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 ...

Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravity, gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or "tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the #Phase and amplitude, phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see ''#Timing, Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal cycle, diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Coast Highway
South Coast Highway is a Western Australian highway. It is a part of the Highway 1 network. With a length of , it runs from Esperance to Walpole roughly in parallel to Western Australia's south coast. Even then the journey is pretty much inland. Approximately from Ravensthorpe lies the Fitzgerald River National Park with beaches, coastal and mountain walking trails and wildflowers. There are three more national parks with abundant wildlife along the journey to Walpole. Albany is a former whaling town and is rich in history. Beyond Walpole, Highway 1 continues as South Western Highway to Perth. Beyond Esperance, Highway 1 continues as Coolgardie–Esperance Highway to Norseman.

Denmark River
The Denmark River is located in the Great Southern region of Western Australia. The river rises near Pardelup and meanders in a southerly direction until it flows through Denmark into Wilson Inlet (along with the Hay River). The traditional owners of the area are the Noongar people, who know the river as Kwoorabup, meaning the place of the Western brush wallaby (place we return to). The river was given its English name in December 1829 by naval ship's surgeon Thomas Braidwood Wilson after his mentor, naval surgeon Alexander Denmark, Physician of the Fleet, Resident Physician at the Royal Hospital Haslar, and past-Physician to the Mediterranean Fleet. Wilson found the river while exploring the area in company of the native Mokare, John Kent (officer in charge of the Commissariat at King George Sound), two convicts and Private William Gough of the 39th Regiment, while his ship ''Governor Phillips'' was being repaired at King George Sound.
