Deep River (Western Australia)
Deep River is a river located in the Great Southern region of Western Australia. The river is under tidal influence for the last of its length. Although generally shallow the Deep River has depths of up to in places. The Deep River is one of the few perennial rivers in Western Australia although 80% of its discharge occurs in winter and spring. The rivers water quality is very good, fresh and low in nutrients. The majority of the catchment of the Deep River is not cleared. The silt and clay content can be high during the winter period. The Deep River begins just west of Lake Muir about 50 km from the coast on the edge of the Yilgarn Plateau. Lake Muir may, in flood, overflow into the Deep River catchment. It flows through a valley between granite hills then wanders across the coastal plain finally entering the Nornalup Inlet on the western side. The two tributaries of the Deep River are the Weld River and Croea Brook. Some features of the river include wide unobstru ...

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.

Nornalup Inlet
Nornalup Inlet ( /ˈnoːnələp ˈɪnlət/ Australian English) is an estuarine body of water on the south coast of the South West of Australia, approximately from Perth. It is approximately in extent, and up to deep. It is fed by the Deep and Frankland Rivers, and communicates with the Walpole Inlet via a natural channel approximately long and deep. The name is Noongar in origin, meaning "the place of the tiger snake" ('' Notechis scutatus''). The estuary is wave dominated and is mostly not modified but the catchment has been substantially cleared. The inlets have a naturally low turbidity but have a high sediment trapping efficiency. The inlets have a total area of , most of the area being found in the central basin. The inlet has a mean depth of . The Walpole - Nornalup inlet system is the only permanently open estuarine system in the South West, giving it great biological diversity. The Casuarina Isles and Goose Island lie off the coast just to the south of the ... [...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] |
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] |
Perennial Stream
A perennial stream is a stream that has continuous flow of surface water throughout the year in at least parts of its catchment during seasons of normal rainfall, Water Supply Paper 494. as opposed to intermittent river, one whose flow is intermittent. In the absence of irregular, prolonged or extreme drought, a perennial stream is a watercourse, or segment, element or emerging body of water which continually delivers groundwater. For example, an damming, artificial disruption of stream, variability in flow or stream selection associated with the activity in hydropower installations, do not affect this status. Perennial streams do not include stagnant water (stream pool, pools and puddle, waterholes), reservoirs, oxbow lake, cutoff lakes and ponds that persist throughout the year. All other streams, or parts of them, should be considered seasonal rivers or lakes. The stream can cycle from intermittent to perpetual through multiple iterations.

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 ...

Nutrient
A nutrient is a substance used by an organism to survive, grow, and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi, and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures, such as hair, scales, feathers, or exoskeletons. Some nutrients can be metabolically converted to smaller molecules in the process of releasing energy, such as for carbohydrates, lipids, proteins, and fermentation products (ethanol or vinegar), leading to end-products of water and carbon dioxide. All organisms require water. Essential nutrients for animals are the energy sources, some of the amino acids that are combined to create proteins, a subset of fatty acids, vitamins and certain minerals. Plants require more diverse minerals absorbed through roots, plus carbon dioxide and oxygen absorbed through leaves. Fungi live on dead or living organic matter and meet nutrient needs from their host. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Walpole-Nornalup National Park
Walpole-Nornalup National Park is a national park in the South West (Western Australia), South West region of Western Australia, south of Perth. It is famous for its towering karri and tingle trees. Eucalyptus jacksonii, Red tingle trees are unique to the Walpole area. The park is part of the larger Walpole Wilderness Area that was established in 2004, an international biodiversity hotspot. History The traditional owners of the area are the Murrum of the Mineng, Minang peoples of the larger Noongar group who have inhabited the region for over 30,000 years. The park is named after the nearby town of Walpole which in turn honours William Walpole, who served alongside James Stirling (Royal Navy officer), James Stirling on HMS ''HMS Warspite (1807), Warspite'' in 1809. The Noongar peoples know the area as Nor-Nor-Nup, meaning the place of the black snake, which was anglicised as Nornalup.
