Munglinup River
The Munglinup River is an ephemeral river in the Goldfields-Esperance region of Western Australia. The headwaters of the river rise near Cheadanup Nature Reserve. It flows in a southerly direction through cleared farmland, then crossing the South Coast Highway near the town of Munglinup before discharging into the Oldfield River, of which it is a tributary, approximately from the coast. For most of the length of the river it is within a vegetated corridor, the surrounding land is mostly cleared for stock with only about 15% remnant vegetation remaining. The river only flows in the winter months and the water is naturally saline or brackish. The only tributary to the river is Clayhole Creek. The word Munglinup is Indigenous Australian in origin and of unknown meaning. The name was first recorded by C.D. Price, a surveyor Surveying or land surveying is the technique, profession, art, and science of determining the terrestrial two-dimensional or three-dimensional pos ...

Oldfield Estuary
Oldfield Estuary is an estuary in the Goldfields-Esperance region of Western Australia. The estuary has a length of and is no wider than with a total area of approximately . The estuary has a main basin area of about and the rest is flood and tidal delta. The Oldfield River and the Munglinup River both discharge into the estuary. Uncleared bushland surrounds the estuary which has high dunes to the east and low sediments to the west. The lagoon is filled with river sediment to the north and beach sand to the south with a long high sandbar that breaks every three to four years. The estuary functions primarily as a result of wave energy. The seagrass ''Ruppia megacarpa ''Ruppia megacarpa'' is a submerged herb species in the genus ''Ruppia'' found in shallow brackish waters.

Sea Level
Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead the midpoint between a mean low and mean high tide at a particular location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. Current sea level rise is mainly caused by human-induced climate change. When temperatures rise, Glacier, mountain glaciers and the Ice sheet, polar ice caps melt, increasing the amount of water in water bodies. Because most of human settlem ...

Ephemeral
Ephemerality (from the Greek word , meaning 'lasting only one day') is the concept of things being transitory, existing only briefly. Academically, the term ephemeral constitutionally describes a diverse assortment of things and experiences, from digital media to types of streams. "There is no single definition of ephemerality". With respect to unique performances, for example, it has been noted that " hemerality is a quality caused by the ebb and flow of the crowd's concentration on the performance and a reflection of the nostalgic character of specific performances". Because different people may value the passage of time differently, ephemerality may be a relative, perceptual concept: "In brief, what is short-lived may not be the object itself, but the attention we afford it".Ronald Beiner, ''Political Philosophy: What It Is and Why It Matters'' (2014), p. 10. Ephemerality and nature Geographical features An ephemeral stream is that which only exists following precipitation. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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.

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.

Munglinup, Western Australia
Munglinup is a small town located in the Shire of Ravensthorpe in the Goldfields–Esperance region of Western Australia. The town lies on the South Coast Highway between Ravensthorpe and Esperance and close to the Munglinup River. The river for most of its course defines the boundary of the Esperance and Ravensthorpe shires. At the Oldfield Estuary, the boundary goes to the eastern shore. The word Munglinup is Noongar in origin and means ''where young people met their in-laws.'' The name first appears on maps made by the Dempster brothers, early settlers of the area in 1868. The region was first opened up for farming in the late 1950s. By the early 1960s, the community asked for a townsite between Esperance and Ravensthorpe to be considered. The townsite was surveyed in 1961 and gazetted in 1962. The surrounding areas produce wheat and other cereal crops. The town is a receival site for Cooperative Bulk Handling The CBH Group (commonly known as CBH, an acronym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldfield River
The Oldfield River is an ephemeral river in the Goldfields-Esperance region of Western Australia that rises inland from the South Coast at the edge of the Yilgarn plateau. The river starts at above sea level then flows in a south easterly direction crossing the South Coast Highway near Munglinup. The river gently undulates through sandstone forming gentle valleys with many granite outcrops, the river then carves deeper valleys through the siltstone before entering the coastal plain. The river is then joined by its tributary, the Munglinup River, before flowing into the Oldfield estuary which discharges into the Southern Ocean. The only other tributary of the Oldfield River is Coujinup Creek. The river is regarded as saline with high nutrient levels, moderate sedimentation, moderate fringing vegetation and has a low flood risk. Named as Oldfield river by the settler Michael Simon Dempster in a letter written in 1866, the river is thought to have been named after Augustus F ...

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 ...

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 ...
