A swamp is a forested wetland. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates periodic inundation or soil saturation. The two main types of swamp are "true" or swamp forests and "transitional" or shrub swamps. In the boreal regions of Canada, the word swamp is colloquially used for what is more formally termed a bog, fen, or muskeg. Some of the world's largest swamps are found along major rivers such as the Amazon, the Mississippi, and the Congo.
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently for years or decades or seasonally for a shorter periods. Flooding results in oxygen-free anoxic processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Constructed wetlands are designed and built to treat municipal and industrial wastewater as well as to divert stormwater runoff. Constructed wetlands may also play a role in water-sensitive urban design.
Soil salinity and dryland salinity are two problems degrading the environment of Australia. Salinity is a concern in most states, but especially in the south-west of Western Australia.
Lake Corangamite, a hypersaline endorheic lake, is located near Colac in the Lakes and Craters region of the Victorian Volcanic Plains of south-west Victoria, Australia. The lake's salinity levels have increased dramatically as the lake level has dropped in recent decades. It is Australia's largest permanent saline lake, covering approximately 230 square kilometres (89 sq mi) with a circumference of 150 kilometres (93 mi). It forms part of the Ramsar-listed Western District Lakes wetland site. The Aboriginal name of the lake is recorded as Kronimite.
Lake Victoria is a 139-hectare (340-acre) shallow saline lake on the Bellarine Peninsula, Victoria in Australia, close to the township of Point Lonsdale and part of the Lonsdale Lakes Nature Reserve administered by Parks Victoria.
Lake Connewarre, a shallow estuarine 880-hectare (2,200-acre) lake on the Barwon River, is located on the Bellarine Peninsula southeast of Geelong in the Australian state of Victoria.
Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. 97% of the water on Earth is salt water and only three percent is fresh water; slightly over two-thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air. Natural sources of fresh water include surface water, under river flow, groundwater and frozen water. Artificial sources of fresh water can include treated wastewater and desalinated seawater. Human uses of water resources include agricultural, industrial, household, recreational and environmental activities.
The Paroo-Darling National Park is a protected national park that is located in the Far West region of New South Wales, in eastern Australia. The 178,053-hectare (439,980-acre) national park spans two distinct regions in the outback area. This region covers the arid catchments of the Paroo River and the Paroo-Darling confluence to the south.
The Nambung River is a river in the Wheatbelt region of Western Australia, 170 kilometres (106 mi) north of Perth. The river drains an area between the towns of Cervantes and Badgingarra. In its lower reaches the Nambung River forms a chain of waterholes in the Nambung Wetlands where it disappears underground into a limestone karst system 5.5 kilometres (3 mi) from the Indian Ocean.
Reedy Lake, historically also known as Lake Reedy, is a shallow 5.5-square-kilometre (2.1 sq mi) intermittent freshwater lake or swamp on the lower reaches of the Barwon River, on the Bellarine Peninsula southeast of Geelong in the Australian state of Victoria.
The Edithvale-Seaford Wetlands is a collection of principally freshwater swamps and marshlands totalling 261 hectares in southeastern Melbourne, Victoria, Australia, about 30 km (19 mi) southeast of Melbourne CBD. It is the largest natural wetland of its type in the Port Phillip and Western Port basins, and is all that remains of the historic Carrum Carrum Swamp, which once covered more than 4,000 hectares from present-day Mordialloc in the north to Frankston in the south.
Toolibin Lake is a seasonal fresh to brackish water perched lake or wooded swamp, in south-western Australia. The lake is contained with a 493-hectare (1,218-acre) nature reserve and it is located about 200 kilometres (124 mi) south-east of Perth, in the Shire of Narrogin, and 40 kilometres (25 mi) east of the town of Narrogin, in the Wheatbelt region of Western Australia. The lake is listed by the Australian Government as a threatened ecological community under the Environment Protection and Biodiversity Conservation Act 1999.
The Forrestdale and Thomsons Lakes Ramsar Site comprises two separate nature reserves, totalling 754 ha in area, protecting two shallow fresh to brackish, seasonal lakes in a suburban and agricultural landscape in south-western Western Australia. It lies in the Swan Coastal Plain bioregion and is used mainly for birdwatching and walking. The site is recognised as being of international importance under the Ramsar Convention on Wetlands, under which it was designated Ramsar Site 481 on 7 June 1990.
The Cheetham Wetlands are 420 hectares of artificial and natural lagoons, created on old salt works land on the western shores of Port Phillip Bay, Australia. The wetlands are approximately 20 kilometres (12 mi) southwest of Melbourne, and sit within the Municipal Councils of Hobsons Bay and Wyndham City.
Butcher Gap Conservation Park is a protected area located in the Limestone Coast of South Australia overlooking Lacepede Bay about 6 kilometres south of the town of Kingston SE. The conservation park was proclaimed under the National Parks and Wildlife Act 1972 in 1990.
Sleaford Mere is a permanent saline lake, located on the Jussieu Peninsula on the south eastern tip of Eyre Peninsula in South Australia about 15 kilometres south west of Port Lincoln. The lake was given its modern name by the British explorer, Matthew Flinders, on 26 February 1802. Since 1969, the lake has been part of the Sleaford Mere Conservation Park and since 2005, it has been listed as a nationally important wetland. The lake and its environs are notable as a venue for recreational pursuits such as canoeing.
Mystic Park is a locality in the Australian state of Victoria. It straddles the Murray Valley Highway between Kerang and Swan Hill, and falls within the Shire of Gannawarra local government area. Mystic Park had a population of 181 people at the time of the 2016 Australian census.
The Raak Plain Boinka is a wilderness area in the state of Victoria, Australia. The boinka groundwater discharge complex is a shallow depression within a region of Mallee dune fields, and contains gypsum flats and salinas, pools of salty water that are mainly fed by groundwater. The distinctive flora of the boinka is largely intact and includes several threatened species.
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non-salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans.
