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 hundred times Perth's current annual water usage. It is currently the single most important source of potable water for the city. Together with the Jandakot Mound in the south of Perth it supplies about 35%–50% of the city's drinking water. However, studies have shown that water levels in the Gnangara Mound have fallen substantially in recent times. This has had a significant impact on nearby groundwater-dependent ecosystems such as the Wanneroo wetlands and the Yanchep caves. The problem has also been causing acidification of the nearby Lakes Gnangara, Jandabup, Wilgarup and Mariginiup. The remaining mound springs of the Swan Coastal Plain depend on the aquifer and are susceptible to any dramatic change in hydrology. It is widely recognised that sustainability of the Mound as a water resource is under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Gnangara
Lake Gnangara is the most southerly of the Wanneroo wetlands in metropolitan Perth, Western Australia. The state government's ''Wetland Atlas'' defines the body of water as a lake. The surrounding terrain consists of low dunes and undulating sand plains. The lake is fed by ground water of the Gnangara Mound which is contained by a thin layer of clay. Previous uses have included diatomaceous earth mining, which may have contributed to changes in the lake's characteristics and ecology. The area is now the subject of a conservation plan and management strategies, and protected from potential disturbance by mining activities. The Lake reserve is an important part of the management of the mound. The lake surroundings were the site of a long term Nyoongar camp as well as a Nyoongar community college.http://slwa.wa.gov.au/pdf/mn/mn3001_3500/mn3014.pdf Nyoongah Community Aboriginal Corporation (NCAC)and Nyoongah Community Incorporated (NCI)Includes Nyoongah Aboriginal Community Colle ...

Perth
Perth is the capital and largest city of the Australian state of Western Australia. It is the fourth most populous city in Australia and Oceania, with a population of 2.1 million (80% of the state) living in Greater Perth in 2020. Perth is part of the South West Land Division of Western Australia, with most of the metropolitan area on the Swan Coastal Plain between the Indian Ocean and the Darling Scarp. The city has expanded outward from the original British settlements on the Swan River, upon which the city's central business district and port of Fremantle are situated. Perth is located on the traditional lands of the Whadjuk Noongar people, where Aboriginal Australians have lived for at least 45,000 years. Captain James Stirling founded Perth in 1829 as the administrative centre of the Swan River Colony. It was named after the city of Perth in Scotland, due to the influence of Stirling's patron Sir George Murray, who had connections with the area. It gained city statu ...

Potable Water
Drinking water is water that is used in drink or food preparation; potable water is water that is safe to be used as drinking water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. Recent work showed that the most important driver of water turnover which is closely linked to water requirements is energy expenditure. For those who work in a hot climate, up to a day may be required. Typically in developed countries, tap water meets drinking water quality standards, even though only a small proportion is actually consumed or used in food preparation. Other typical uses for tap water include washing, toilets, and irrigation. Greywater may also be used for toilets or irrigation. Its use for irrigation however may be associated with risks. Water may also be unacceptable due to l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jandakot Mound
The Jandakot Mound, or Jandakot Groundwater Mound, is an unconfined aquifer in south-western Western Australia. It is the smaller of the two main shallow aquifers near Perth (the other being the Gnangara Mound, north of the Swan River) that together supply about 40% of Perth's drinking water. Its highest point lies about south of Perth's central business district. It stretches from the Swan River in the north to the Serpentine River in the south, and from the Indian Ocean in the west to the Darling Scarp and Southern River in the east, covering an area of about . The Jandakot Mound is a sand aquifer with a saturated thickness of up to . It contains an estimated of fresh water, and the annual recharge can reach . It contributes annually to Perth's municipal supply of drinking water and is also heavily used for private supplies. Where it is close to the surface, it supports extensive wetland systems, the most important of which are Beeliar Wetlands, Forrestdale and Tho ...

Wanneroo Wetlands
The Wanneroo wetlands are a series of wetlands, swamps and lakes that occur on the Swan Coastal Plain of Perth, Western Australia. They are linked very closely to the Gnangara Mound. They are in part, incorporated into the Yellagonga Regional Park and also referred to as Yellagonga wetlands. Description The wetlands comprise a series of named lakes, including Lake Joondalup (or Craigie Lake), Lake Goolelal (or Welshes Lake), Jandabup Lake (or Big Dundebar Lake), Yonderup Lake, Nowergup Lake (or Narago Lake), Coogee Springs, Neerabup Lake (or Pappas Swamp), Lake Gnangara, Mariginiup Lake, Pippidinny and Boonaddy Swamps, and Loch McNess (or Yanchep Lake).

Yanchep, Western Australia
Yanchep is an outer coastal suburb of Perth, Western Australia, north of the Perth CBD. It is a part of the City of Wanneroo local government area. Originally a small crayfishing settlement, it was developed by entrepreneur Alan Bond in the 1970s for the 1977 America's Cup. The area covers the urban centre of Yanchep as well as Yanchep National Park in its entirety. Geography Yanchep is bounded to the north-west by Two Rocks and to the south by the rural localities of Eglinton, Carabooda and Pinjar. The non-metropolitan Shires of Gingin and Chittering surround Yanchep's northern and eastern boundaries. West of Yanchep is the Indian Ocean. For a suburb it is extremely large, covering over and taking up almost the entire northern and north-eastern portion of the City of Wanneroo. Despite this, Yanchep's urban concentration is almost entirely located in a small enclave around Yanchep Beach Road, near the coast. History For thousands of years prior to the arrival of Eur ...

Lake Wilgarup
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Mariginiup
The Wanneroo wetlands are a series of wetlands, swamps and lakes that occur on the Swan Coastal Plain of Perth, Western Australia. They are linked very closely to the Gnangara Mound. They are in part, incorporated into the Yellagonga Regional Park and also referred to as Yellagonga wetlands.

Mound Springs Of The Swan Coastal Plain
Assemblages of plants and invertebrate animals of tumulus (organic mound) springs of the Swan Coastal Plain are ecological communities in Western Australia. They have been managed under a number of other, similar names, including Mound springs of the Swan Coastal Plain and Communities of Tumulus Springs (Organic Mound Springs, Swan Coastal Plain). The tumulus mounds were common to a narrow range of groundwater discharge at the boundary of 'bassendean sand' and 'guildford clay', along the edge of the Gnangara Mound aquifer. The communities are critically endangered. Description At the edge of the Gnangara Mound, where heavy guildford clays meet the bassandean dune system, bogs and swamps are created by the discharge of water from this aquifer. The clay and sand intersection on the Swan Coastal Plain, near the Darling Scarp, also produces permanent springs, giving rise to peat and sand mounds containing plant and invertebrate assemblages. The continuing vegetative growth produces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrology
Hydrology () is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and environmental watershed sustainability. A practitioner of hydrology is called a hydrologist. Hydrologists are scientists studying earth or environmental science, civil or environmental engineering, and physical geography. Using various analytical methods and scientific techniques, they collect and analyze data to help solve water related problems such as environmental preservation, natural disasters, and water management. Hydrology subdivides into surface water hydrology, groundwater hydrology (hydrogeology), and marine hydrology. Domains of hydrology include hydrometeorology, surface hydrology, hydrogeology, drainage-basin management, and water quality, where water plays the central role. Oceanography and meteorology are not included because water is only one of many important aspects within those fields. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...
