Ramsar Convention
The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of Ramsar site, Ramsar sites (wetlands). It is also known as the Convention on Wetlands. It is named after the city of Ramsar, Mazandaran, Ramsar in Iran, where the convention was signed in 1971. Every three years, representatives of the contracting parties meet as the Ramsar Convention#Conference of the Contracting Parties, Conference of the Contracting Parties (COP), the policy-making organ of the wetland conservation, convention which adopts decisions (site designations, resolutions and recommendations) to administer the work of the convention and improve the way in which the parties are able to implement its objectives. In 2022, COP15 was held in Montreal, Canada. List of wetlands of international importance The list of wetlands of international importance included 2,531 Ramsar site, Ramsar sites in Februa ...

Tringa Stagnatilis
The marsh sandpiper (''Tringa stagnatilis'') is a small wader. It is a rather small shank, and breeds in open grassy steppe and taiga wetlands from easternmost Europe to the Russian Far East. The genus name ''Tringa'' is the Neo-Latin name given to the green sandpiper by Aldrovandus in 1599 based on Ancient Greek ''trungas'', a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific ''stagnatilis'' is from Latin ''stagnum'', "swamp". Description The marsh sandpiper resembles a small elegant greenshank, with a long fine bill and very long yellowish legs. Like the greenshank, it is greyish brown in breeding plumage, paler in winter, and has a white wedge up its back that is visible in flight. However, it is more closely related to the common redshank and the wood sandpiper. Together, they form a group of smallish shanks which tend to have red or reddish legs, and in breeding plumage are generally a subdued, light brown above with some darker mott ...

Cambridge Gulf
Cambridge Gulf is a gulf on the north coast of the Kimberley region of Western Australia. Many rivers flow into the gulf, including the Ord River, Pentecost River, Durack River, King River and the Forrest River, making the environment an estuarine one. The gulf experiences two large tidal flows each day between . The town of Wyndham, the area's principal port, lies on its eastern bank at the lower part of the gulf and is approximately by road west-north-west of Kununurra. Cambridge Gulf is a gulf within a gulf, being at the southern extremity of the Joseph Bonaparte Gulf, in the Timor Sea. The entrance of the Gulf is defined by Cape Domett on the eastern shore, Lacrosse Island in the middle, and the Cape Dussejour on the western shore, with King Shoals and Medusa Banks out in Joseph Bonaparte Gulf beyond Lacrosse Island. The conjunction between the gulf and the lower regions of the Ord River (the eastern arm), and the Durack and Pentecost Rivers (the western ...

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 percent by weight (% w/w). At (the boiling temper ...

Claypan
Claypan is a dense, compact, slowly permeable layer in the subsoil. It has a much higher clay content than the overlying material, from which it is separated by a sharply defined boundary. The dense structure restricts root growth and water infiltration. Therefore, a perched water table might form on top of the claypan. In the Canadian classification system, claypan is defined as a clay-enriched illuvial B (Bt) horizon. Location Claypan is present in a wide area of the central United States (about 4 million ha) across multiple states such as Kansas, Oklahoma, and Illinois. It can also be found in Australia throughout the south-west Queensland. Formation Claypan is formed in different parent materials depending on geological locations, such as floodplains. The formation of the claypan relates to a lack of vegetation coverage, soil particle size distribution, and high rainfall. The lack of vegetation coverage makes soil become more susceptible to raindrop attacks. When the raindr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wet Season
The wet season (sometimes called the rainy season or monsoon season) is the time of year when most of a region's average annual rainfall occurs. Generally, the season lasts at least one month. The term ''green season'' is also sometimes used as a euphemism by tourist authorities. Areas with wet seasons are dispersed across portions of the tropics and subtropics. Under the Köppen climate classification, for tropical climates, a wet season month is defined as a month where average precipitation is or more. In contrast to areas with savanna climates and monsoon regimes, Mediterranean climates have wet winters and dry summers. Dry and rainy months are characteristic of tropical seasonal forests: in contrast to tropical rainforests, which do not have dry or wet seasons, since their rainfall is equally distributed throughout the year.Elisabeth M. Benders-Hyde (2003)World Climates.Blue Planet Biomes. Retrieved on 2008-12-27. Some areas with pronounced rainy seasons will see a break ...

Dry Season
The dry season is a yearly period of low rainfall, especially in the tropics. The weather in the tropics is dominated by the tropical rain belt, which moves from the northern to the southern tropics and back over the course of the year. The temperate counterpart to the tropical dry season is summer or winter. Rain belt The tropical rain belt lies in the southern hemisphere roughly from November to March; during that time the northern tropics have a dry season with sparser precipitation, and days are typically sunny throughout. From May to September, the rain belt lies in the northern hemisphere, and the southern tropics have their dry season. Under the Köppen climate classification, for tropical climates, a dry season month is defined as a month when average precipitation is below . The rain belt reaches roughly as far north as the Tropic of Cancer and as far south as the Tropic of Capricorn. Near these latitudes, there is one wet season and one dry season annually. At the ...

Lake Kununurra
Lake Kununurra is a freshwater man-made reservoir located in the Ord River valley. The lake was formed in 1963 by the construction of the Ord Diversion Dam in Kununurra, northern Western Australia, which was built to supply water to the Ord River Irrigation Area. Prior to the diversion dam construction a natural permanent waterhole (or lake) held back by the Bandicoot Bar was known as "Carlton Reach", which was reputed to be the largest waterhole in the Kimberley. Description The lake stretches for upstream from the Diversion Dam at towards the larger Lake Argyle dam at . At the town of Kununurra the lake is connected to Lily Creek Lagoon. It contains freshwater crocodiles and 21 fish species, and is widely used for recreational fishing and boating by the residents of Kununurra and tourists. Because of the stable water levels in Lake Kununurra and its associated wetlands, it has well-developed fringing vegetation of grassland, rushes and woodland. The wetland system of t ...

Lake Argyle
Lake Argyle is Western Australia's largest and Australia's second largest Freshwater lake, freshwater man-made Reservoir (water), reservoir by volume. The reservoir is part of the Ord River (Kimberley)#Ord River Irrigation Scheme, Ord River Irrigation Scheme and is located near the Kimberley (Western Australia), East Kimberley town of Kununurra. The lake flooded large parts of the Shire of Wyndham-East Kimberley on the Kimberley (Western Australia), Kimberley Plateau about inland from the Joseph Bonaparte Gulf, close to the border with the Northern Territory. The primary inflow is the Ord River, while the Bow River (Kimberley region, Western Australia), Bow River and many other smaller creeks also flow into the dam. The lake is a A Directory of Important Wetlands in Australia, DIWA-listed wetland. Lake Argyle and Lake Kununurra were listed in 1990 as Ramsar Convention protected wetlands. Argyle mine was previously situated here from 1985 until November 2020 following several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoir
A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aq ...

Nature Reserve
A nature reserve (also known as a wildlife refuge, wildlife sanctuary, biosphere reserve or bioreserve, natural or nature preserve, or nature conservation area) is a protected area of importance for flora, fauna, funga, or features of geological or other special interest, which is reserved and managed for purposes of Conservation (ethic), conservation and to provide special opportunities for study or research. They may be designated by government institutions in some countries, or by private landowners, such as charities and research institutions. Nature reserves fall into different IUCN protected area categories, IUCN categories depending on the level of protection afforded by local laws. Normally it is more strictly protected than a nature park. Various jurisdictions may use other terminology, such as ecological protection area or private protected area in legislation and in official titles of the reserves.

Wyndham, Western Australia
Wyndham is the northernmost town in the Kimberley region of Western Australia, northeast of Perth via the Great Northern Highway. It was established in 1886 to service a new goldfield at Halls Creek, and it is now a port and service centre for the east Kimberley with a population of 941 as of the 2021 census. Aboriginal and Torres Strait Islander people make up 54% of the population. Wyndham comprises two areas - the original town site at Wyndham Port situated on Cambridge Gulf, and by road to the south, the Three Mile area with the residential and shopping area for the port, also founded in 1886. Wyndham is part of the Shire of Wyndham-East Kimberley. History Wyndham is within traditional Doolboong country. The first European to visit the area was Phillip Parker King in 1819. He was instructed to find a river "likely to lead to an interior navigation into the great continent". He sailed into Cambridge Gulf, which he named after the Duke of Cambridge, and then sailed ...
