Lake Burragorang
Lake Burragorang is a man-made reservoir in the lower Blue Mountains of New South Wales, Australia, serving as a major water supply for greater metropolitan Sydney. The dam impounding the lake, the Warragamba Dam, is located approximately southwest of the Sydney central business district. Lake Burragorang is within the World Heritage Site of the Greater Blue Mountains Area. The reservoir collects water from the converged flows of the Coxs, Kowmung, Nattai, Wingecarribee, Wollondilly, and Warragamba rivers and their associated tributaries, all within the Nepean and Hawkesbury River catchment. Pre-lake history Before the construction of the dam, Burragorang Valley had been inhabited by white settlers since the 19th century, and for thousands of years before, the Burragorang valley was part of the tribal lands of the Gundungarra nation, an indigenous tribe that called the Burragorang valley, along with the Blue Mountains and Megalong Valley, their tribal land.

Water Supply
Water supply is the provision of water by public utilities, commercial organisations, community endeavors or by individuals, usually via a system of pumps and pipes. Public water supply systems are crucial to properly functioning societies. These systems are what supply drinking water to populations around the globe. Aspects of service quality include continuity of supply, water quality and water pressure. The institutional responsibility for water supply is arranged differently in different countries and regions (urban versus rural). It usually includes issues surrounding policy and regulation, service provision and standardization. The cost of supplying water consists, to a very large extent, of fixed costs (capital costs and personnel costs) and only to a small extent of variable costs that depend on the amount of water consumed (mainly energy and chemicals). Almost all service providers in the world charge tariffs to recover part of their costs. Water supply is a separate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nepean River
Nepean River (Darug: Yandhai), is a major perennial river, located in the south-west and west of Sydney, New South Wales, Australia. The Nepean River and its associated mouth, the Hawkesbury River, almost encircles the metropolitan region of Sydney. The headwaters of the Nepean River rise near Robertson, about south of Sydney and about from the Tasman Sea. The river flows north in an unpopulated water catchment area into Nepean Reservoir, which supplies potable water for Sydney. North of the dam, the river forms the western edge of Sydney, flowing past the town of Camden and the city of Penrith, south of which flowing through the Nepean Gorge. Near Wallacia it is joined by the dammed Warragamba River; and north of Penrith, near Yarramundi, at its confluence with the Grose River, the Nepean becomes the Hawkesbury River. Changes to the natural flow of the river The river supplies water to Sydney's five million people as well as supplying agricultural production. This, c ...

Yerranderie, New South Wales
Yerranderie is a ghost town located near Kanangra-Boyd National Park of New South Wales, Australia in Wollondilly Shire. History Yerranderie was formerly a silver mining town of 2000 people, but the mining industry collapsed in 1927, and the town was cut off from direct access from Sydney by the establishment of the Warragamba Dam and Lake Burragorang in 1959. Country singer Frank Ifield immortalised the event with his song “Yerranderie”. The Yerranderie Post Office opened on 1 November 1899 and closed in 1958. The town is now divided into two sections, the residential township adjacent to a private airstrip and the historic site one kilometre further west. The area is surrounded by abandoned mine shafts and mining relics. Accessible mainly by dirt road from Oberon, New South Wales 70 km to the west; another route passes through Oakdale, New South Wales to the east, but that road is closed to public access as it passes through a water catchment area.

Lake Burragorang Lookout
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 ic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2019–20 Australian Bushfire Season
The 201920 Australian bushfire season (Black Summer), was a period of bushfires in many parts of Australia, which, due to its unusual intensity, size, duration, and uncontrollable dimension, is considered a megafire. The Australian National University reported that the area burned in 2019/2020 was "well below average" due to low fuel levels and fire activity in unpopulated parts of Northern Australia, but that "Despite low fire activity overall, vast forest fires occurred in southeast Australia from southeast Queensland to Kangaroo Island." In June 2019 the Queensland Fire and Emergency Service acting director warned of the potential for an early start to the bushfire season which normally starts in August. The warning was based on the Northern Australia bushfire seasonal outlook noting exceptional dry conditions and a lack of soil moisture, combined with early fires in central Queensland. Throughout the summer, hundreds of fires burnt, mainly in the southeast of the country ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Sink
A carbon sink is anything, natural or otherwise, that accumulates and stores some carbon-containing chemical compound for an indefinite period and thereby removes carbon dioxide () from the atmosphere. Globally, the two most important carbon sinks are vegetation and the ocean. Public awareness of the significance of sinks has grown since passage of the 1997 Kyoto Protocol, which promotes their use as a form of carbon offset. There are also different strategies used to enhance this process. Soil is an important carbon storage medium. Much of the organic carbon retained in the soil of agricultural areas has been depleted due to intensive farming. " Blue carbon" designates carbon that is fixed via the ocean ecosystems. Mangroves, salt marshes and seagrasses make up a majority of ocean plant life and store large quantities of carbon. Many efforts are being made to enhance natural sequestration in soils and the oceans. In addition, a range of artificial sequestration initiatives are ...

Extreme Weather
Extreme weather or extreme climate events includes unexpected, unusual, severe, or unseasonal weather; weather at the extremes of the historical distribution—the range that has been seen in the past. Often, extreme events are based on a location's recorded weather history and defined as lying in the most unusual ten percent. The main types of extreme weather include heat waves, cold waves and tropical cyclones. The effects of extreme weather events are seen in rising economic costs, loss of human lives, droughts, floods, landslides and changes in ecosystems. There is evidence to suggest that climate change is increasing the periodicity and intensity of some extreme weather events. Confidence in the attribution of extreme weather and other events to anthropogenic climate change is highest in changes in frequency or magnitude of extreme heat and cold events with some confidence in increases in heavy precipitation and increases in the intensity of droughts. Current evidence and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
