The Bradfield Scheme was devised by Dr John Job Crew Bradfield (1867-1943), a Queensland born civil engineer, who also designed the Sydney Harbour Bridge, and the Brisbane Story Bridge. John Job Crew Bradfield ( December 26, 1867 - September 23, 1943) was an Australian engineer best known as the designer of the } The Sydney Harbour Bridge is a Steel arch bridge across Sydney Harbour that carries rail vehicular and pedestrian traffic between the Sydney central business The Story Bridge is a Cantilever bridge and the second crossing of the Brisbane River. The inland irrigation project that Dr Bradfield proposed, was designed to irrigate and drought-proof much of the Queensland interior, as well as large areas of South Australia. Irrigation is an artificial application of water to the soil usually for assisting in growing crops A drought is an extended period of months or years when a region notes a deficiency in its water supply Queensland is a state of Australia, occupying the north-eastern corner of the mainland continent South Australia is a state of Australia in the southern central part of the country The scheme would require large pipes, tunnels, pumps and dams. Pipeline transport is the transportation of goods through a pipe.
The scheme involved the diverting of water from the upper reaches of the Johnson, Tully, Herbert, Burdekin and Flinders rivers. The Tully River is a River situated in northern Queensland. The catchment drains the wettest in the country and was previously known as the Mackay River The Herbert River is a river located in Far North Queensland, Australia. The Burdekin River in Queensland, Australia rises on the western slope of the Seaview Range and flows into the Pacific Ocean at Upstart The Flinders River is the longest river in Queensland, Australia at about 840 km These Queensland rivers are fed by the monsoon, and currently flow out into the ocean. Queensland is a state of Australia, occupying the north-eastern corner of the mainland continent The water would enter the Thomson River on the other side of the Great Dividing Range and eventually flow south west to Lake Eyre. The Thomson River is situated in western Queensland, Australia, and forms part of the Lake Eyre Basin. The Great Dividing Range, also known as the Eastern Highlands, is Australia 's most substantial Mountain range. Lake Eyre (pronounced "air" is the lowest point in Australia, at approximately ( AHD) below sea level and on the rare occasions that it fills the

Benefits
Controlling and reducing the flow of northern rivers into the ocean may benefit the Great Barrier Reef as fresh water causes coral bleaching, and the excess nutrients in the rivers from coastal farming and development, are toxic to the reef. The Great Barrier Reef is the largest Coral reef system in the world composed of over 2900 individual reefs and 900 islands stretching for 2600 kilometres (1600 mi Coral bleaching is the loss of color of Corals due to stress-induced expulsion of symbiotic Unicellular Algae or due to the loss of pigmentation within A nutrient is food or chemicals that an organism needs to live and grow or a substance used in an organism's metabolism which must be taken in from its environment The scheme would reduce the massive natural erosion problems in areas of Central Queensland. Erosion is the carrying away or displacement of solids ( Sediment, Soil, rock and other particles usually by the agents of currents such as wind
Extra water and vegetation in the interior may then produce changes to the climate of Australia. Vegetation is a general term for the plant life of a region it refers to the Ground cover provided by plants The climate of Australia varies widely but by far the largest part of Australia is Desert or Semi-arid – 40% of the landmass is covered by This may increase the rainfall in areas of Southern Queensland and Northern New South Wales. Extra rainfall would drought-proof Eastern Queensland; and thereby improve river inflows into the Murray-Darling River system. The Murray-Darling Basin is 3375km long drains one-seventh of the Australian land mass and is currently by far the most significant agricultural area in Australia This in turn would drought-proof much of New South Wales and Victoria.
Support
This scheme was seen during World War II and much of the twentieth century, as an essential step in building a secure and prosperous nation. It was regarded as the next great water engineering project to build after the Snowy Mountains Scheme. The Snowy Mountains Scheme is a Hydroelectricity and irrigation complex in south-east Australia
A modified scheme was strongly supported on this site by an independent candidate at the last Australian senate election in Queensland. [1] Revised Bradfield schemes are being assessed, and may include damming and running the Nicholson and Leichhardt Rivers in the Gulf of Carpentaria, into the Flinders River, as well as the rivers proposed by Bradfield. The Gulf of Carpentaria is a large shallow sea enclosed on three sides by northern Australia and bounded on the north by the Arafura Sea (the body of water that lies
Objections
Objections to the scheme involve:
- The high cost
- The extreme evaporation rate in the interior
- Coastal developments now use much more water than earlier leaving a smaller surplus to divert
- It is only speculation that a climate change would result. Evaporation is the process by which Molecules in a Liquid state (e Saudi Arabia, which is very dry, is surrounded by seas containing far more water that an enhanced river would provide.
