Swan Coastal Plain
The Swan Coastal Plain in Western Australia is the geographic feature which contains the Swan River as it travels west to the Indian Ocean. The coastal plain continues well beyond the boundaries of the Swan River and its tributaries, as a geological and biological zone, one of Western Australia's Interim Biogeographic Regionalisation for Australia regions.IBRA Version 6.1 data It is also one of the distinct physiographic provinces of the larger West Australian Shield division.

Coastal Plain
A coastal plain (also coastal plains, coastal lowland, coastal lowlands) is an area of flat, low-lying land adjacent to a sea coast. A fall line commonly marks the border between a coastal plain and an upland area. Formation Coastal plains can form in one of two ways; some begin as a continental shelf, a flat piece of land located below sea level, and are created when the ocean level falls, exposing the land. Others develop when river currents carry sediment into the ocean, which is deposited and builds up over time until it forms a coastal plain. They are generally separated from the rest of the interior by proximate landforms, like mountains. Locations Some of the largest coastal plains are in Alaska and the southeastern United States. The Gulf Coastal Plain of North America extends northwards from the Gulf of Mexico along the Lower Mississippi River to the Ohio River, which is a distance of about . The Atlantic Coastal Plain runs from the New York Bight to Florida. The C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australasian Realm
The Australasian realm is one of eight biogeographic realms that is coincident with, but not (by some definitions) the same as, the geographical region of Australasia. The realm includes Australia, the island of New Guinea (comprising Papua New Guinea and the Indonesian province of Papua), and the eastern part of the Indonesian archipelago, including the island of Sulawesi, the Moluccas (the Indonesian provinces of Maluku and North Maluku), and the islands of Lombok, Sumbawa, Sumba, Flores, and Timor, often known as the Lesser Sundas. The Australasian realm also includes several Pacific island groups, including the Bismarck Archipelago, Vanuatu, the Solomon Islands, and New Caledonia. New Zealand and its surrounding islands are a distinctive sub-region of the Australasian realm. The rest of Indonesia is part of the Indomalayan realm. In the classification scheme developed by Miklos Udvardy, New Guinea, New Caledonia, Solomon Islands and New Zealand are placed in the ...

Coquina
Coquina () is a sedimentary rock that is composed either wholly or almost entirely of the transported, abraded, and mechanically sorted fragments of mollusks, trilobites, brachiopods, or other invertebrates. The term ''coquina'' comes from the Spanish language, Spanish word for "cockle (bivalve), cockle" and "shellfish". For a sediment to be considered to be a coquina, the particles composing it should average or greater in size. Coquina can vary in hardness from poorly to moderately cementation (geology), cemented. Incompletely consolidated and poorly cemented coquinas are considered grainstones in the Dunham classification system for carbonate sedimentary rocks. A well-cemented coquina is classified as a biosparite (fossiliferous limestone) according to the Folk classification, Folk classification of sedimentary rocks. Coquinas accumulate in high-energy marine and Lacustrine deposits, lacustrine environments where currents and waves result in the vigorous winnowing, abrasion, ...

Lake Pinjar
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or large la ...

Peel Inlet
The Peel-Harvey Estuarine System () is a natural estuarine system that lies roughly parallel to the coast of Western Australia and south of the town of Mandurah. The strip of land between the Indian Ocean and the estuarine system carries the Old Coast Road and to the east is the Forrest Highway which is the main thoroughfare between Perth and the coastal towns of the south west corner of the state including Bunbury and Busselton. Description The estuarine system, which the Bindjareb Noongar people call , covers an area of approximately in total, with an average water depth of about . The Harvey River discharges into the extreme southern end of the elongated Harvey Estuary, which has an area of about . This in turn feeds into the south-western corner of the more northerly Peel Inlet which is roughly circular and occupies an area of about . The Serpentine River and Murray Rivers discharge into the eastern edges of Peel Inlet. A long channel, the Mandurah Estuary (also ...

Serpentine River (Western Australia)
The Serpentine River is a river in the South West region of Western Australia. It is known as Waangaamaap Bilya to the Indigenous Bindjareb people, who met, lived and fished there before British settlement. The river rises in the Darling Scarp below Bowerling Hill and flows westward crossing Albany Highway north of North Bannister. The river continues northwest through the Youarling State Forest then the Serpentine National Park. The river flows through Serpentine Dam then flows over Serpentine Falls just south of Jarrahdale as it comes off the Scarp and onto the Swan Coastal Plain. The river continues west and crosses the South Western Highway then flows past the town of Serpentine. The river then veers south and continues until it discharges into the Peel Inlet near Mandurah. The upper reaches of the river flow into Serpentine Dam, which provides drinking water to the Perth metropolitan area. The only tributary to the Serpentine River is Big Brook. Additional ...

Ellen Brook
Ellen Brook is an ephemeral stream which runs from south of Gingin to the Swan River in Western Australia. Overview The headwaters of Ellen Brook start south of Gingin, in the Wheatbelt region. From there, Ellen Brook travels south, generally parallel and to the east of Brand Highway, through agricultural land. Near Muchea, Ellen Brook passes under Brand Highway, Granary Drive and Tonkin Highway. From there, it heads south, between Great Northern Highway and Muchea South Road, passing to the west of RAAF Base Pearce in Bullsbrook, before reaching Upper Swan, where it passes under Muchea South Road, past residential areas in The Vines and Belhus, before joining the Swan River in the Swan Valley. Tributaries to the west of Ellen Brook are sourced by groundwater flowing from the Gnangara Mound The Gnangara Mound is an area north of Perth, Western Australia where a large mound of sandy soil reaches an elevation of about . It stores about of fresh water, about one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
