Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root brak. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment.
The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes in the mid-east region of North America that connect to the Atlantic Ocean via the Saint Lawrence River. There are five lakes, which are Superior, Michigan, Huron, Erie, and Ontario and are in general on or near the Canada–United States border. Hydrologically, lakes Michigan and Huron are a single body joined at the Straits of Mackinac. The Great Lakes Waterway enables modern travel and shipping by water among the lakes.
The Great Salt Lake is the largest saltwater lake in the Western Hemisphere and the eighth-largest terminal lake in the world. It lies in the northern part of the U.S. state of Utah and has a substantial impact upon the local climate, particularly through lake-effect snow. It is a remnant of Lake Bonneville, a prehistoric body of water that covered much of western Utah.
Hudson Bay, sometimes called Hudson's Bay, is a large body of saltwater in northeastern Canada with a surface area of 1,230,000 km2 (470,000 sq mi). It is located north of Ontario, west of Quebec, northeast of Manitoba and southeast of Nunavut, but politically entirely part of Nunavut. It is an inland marginal sea of the Arctic Ocean. It drains a very large area, about 3,861,400 km2 (1,490,900 sq mi), that includes parts of southeastern Nunavut, Alberta, Saskatchewan, Ontario, Quebec, all of Manitoba, and parts of the U.S. states of North Dakota, South Dakota, Minnesota, and Montana. Hudson Bay's southern arm is called James Bay.
James Bay is a large body of water located on the southern end of Hudson Bay in Canada. Both bodies of water extend from the Arctic Ocean, of which James Bay is the southernmost part. Despite bordering the Canadian provinces of Quebec and Ontario, the bay and the islands within it, the largest of which is Akimiski Island, are politically part of Nunavut.
The Salton Sea is a shallow, landlocked, highly saline body of water in Riverside and Imperial counties at the southern end of the U.S. state of California. It lies on the San Andreas Fault within the Salton Trough, which stretches to the Gulf of California in Mexico.
Lake Okeechobee, also known as Florida's Inland Sea, is the largest freshwater lake in the U.S. state of Florida. It is the tenth largest natural freshwater lake among the 50 states of the United States and the second-largest natural freshwater lake contained entirely within the contiguous 48 states, after Lake Michigan.
Devils Lake is a lake in the U.S. state of North Dakota. It is the largest natural body of water and the second-largest body of water in North Dakota after Lake Sakakawea. It can reach a level of 1,458 ft (444 m) before naturally flowing into the Sheyenne River via the Tolna Coulee. On June 27, 2011, it reached an unofficial historical high elevation of 1,454.3 ft (443.3 m). The cities of Devil's Lake and Minnewaukan take their name from the lake as does the Spirit Lake Reservation, which is located on the lake's southern shores.
The James Bay Project refers to the construction of a series of hydroelectric power stations on the La Grande River in northwestern Quebec, Canada by state-owned utility Hydro-Québec, and the diversion of neighbouring rivers into the La Grande watershed. It is located between James Bay to the west and Labrador to the east, and its waters flow from the Laurentian Plateau of the Canadian Shield. The project covers an area the size of New York State and is one of the largest hydroelectric systems in the world. It has cost upwards of US$20 billion to build and has an installed generating capacity of 15,244 megawatts, at the cost of 7,000 square miles of Cree hunting lands. If fully expanded to include all of the original planned dams, as well as the additional James Bay II projects, the system would generate a total of 27,000 MW, making it the largest hydroelectric system in the world. It has been built since 1974 by James Bay Energy (SDBJ) for Hydro-Québec.
A tidal marsh is a marsh found along rivers, coasts and estuaries which floods and drains by the tidal movement of the adjacent estuary, sea or ocean. Tidal marshes experience many overlapping persistent cycles, including diurnal and semi-diurnal tides, day-night temperature fluctuations, spring-neap tides, seasonal vegetation growth and decay, upland runoff, decadal climate variations, and centennial to millennial trends in sea level and climate.
The Robert-Bourassa generating station, formerly known as La Grande-2 (LG-2), is a hydroelectric power station on the La Grande River that is part of Hydro-Québec's James Bay Project in Canada. The station can generate 5,616 MW and its 16 units were gradually commissioned between 1979 and 1981. Annual generation is in the vicinity of 26500 GWh.
Thomas William Kierans, FCSCE, P. Eng. was an engineer. He was the originator and principal proponent of the Great Recycling and Northern Development Canal or GRAND Canal.
The St. Lucie River is a 35-mile-long (56 km) estuary linked to a coastal river system in St. Lucie and Martin counties in the Florida, United States. The St. Lucie River and St. Lucie Estuary are an "ecological jewel" of the Treasure Coast, central to the health and well-being of the surrounding communities. The river is part of the larger Indian River Lagoon system, the most diverse estuarine environment in North America with more than 4,000 plant and animal species, including manatees, oysters, dolphins, sea turtles and seahorses.
Caernarvon is an unincorporated community in St. Bernard Parish, Louisiana, United States. The name of the community is from a plantation originally located here. The plantation's name is widely believed to be from a similarly named town and castle in Wales. Names of antebellum plantations in the American South were often reflective of European roots and aspirations of grandeur; two upriver Mississippi River plantations, Nottoway near White Castle, Louisiana, and Sans Souci near Osceola, Arkansas, are two examples of this tradition.
Water exports involve exporting freshwater from one country to another. Large increases in human population and economic growth throughout the world during the twentieth century placed a huge stress on the world’s freshwater resources. Combined with climate change, they are expected to place an even greater demand on water resources in this century. Water shortages have become an international concern, and freshwater has been described as “blue gold” and “the oil of the 21st Century.”
The Peripheral Canal was a series of proposals starting in the 1940s to divert water from California's Sacramento River, around the periphery of the San Joaquin-Sacramento River Delta, to uses farther south. The canal would have attempted to resolve a problem with the quality of water pumped south. Pumps create such a powerful suction that the boundary between freshwater to saltwater has shifted inland, negatively affecting the environment. The pumps have increased by 5 to 7 million acre-feet the amount of water exported each year to the Central Valley and Southern California. However, the peripheral canal as proposed would have reduced the overall freshwater flow into the Delta and move the freshwater-saltwater interface further inland, causing damage to Delta agriculture and ecosystems.
The Manych Ship Canal is a canal between the Black Sea lagoon the Sea of Azov and the Caspian Sea.
The phenomenon of paleoflooding is apparent in the geologic record over various spatial and temporal scales. It often occurred on a large scale, and was the result of either glacial ice melt causing large outbursts of freshwater, or high sea levels breaching bodies of freshwater. If a freshwater outflow event was large enough that the water reached the ocean system, it caused changes in salinity that potentially affected ocean circulation and global climate. Freshwater flows could also accumulate to form continental glacial lakes, and this is another indicator of large-scale flooding. In contrast, periods of high global sea level could cause marine water to breach natural dams and flow into bodies of freshwater. Changes in salinity of freshwater and marine bodies can be detected from the analysis of organisms that inhabited those bodies at a given time, as certain organisms are more suited to live in either fresh or saline conditions.
The Salt Water Barrier was a proposed project on the estuary of the Delaware River, which was projected in the late 1950s to convert the lower reaches of the Delaware into a freshwater lake. The barrier was proposed as a 30-foot (9.1 m) high dam near New Castle, Delaware, 53,300 feet (16,200 m) long, equipped with locks for the passage of shipping to Wilmington and Philadelphia. A study for the project was authorized by Congress in 1958, with engineering evaluations and public hearings by the U.S. Army Corps of Engineers. The prime purpose of the project was to develop the lower river as a source of drinking water for communities along the lower river. Objections to the barrier included concerns about the oyster industry, shipping constraints, increased shoaling, ice formation, and most importantly, the possibility of trapping pollutants above the barrier. The project was found to be technically feasible, but not economically practical. It was not included in the final Delaware River Basin Report of 1962, which proposed reservoirs higher in the Delaware River basin, and no further action was taken.
A Coastal reservoir is a type of reservoir to store fresh water on sea coast area near a river delta. Saemanguem in South Korea, Marina Barrage in Singapore, Qingcaosha and Plover Cove in China, Delta Works in Netherlands, and Thanneermukkom Bund in India are a few existing coastal reservoirs.
