The Jubilee River is an artificial flood-relief channel in southern England. It is 11.6 km (7.2 mi) long [ 1 ] and is on average 45 metres (148 feet) wide. [ 2 ] It was constructed in the late 1990s and early 2000s to take overflow from the River Thames and so alleviate flooding to areas in and around the towns of Maidenhead , Windsor , and ...
The Hjulström curve, named after Filip Hjulström (1902–1982), is a graph used by hydrologists and geologists to determine whether a river will erode, transport, or deposit sediment. It was originally published in his doctoral thesis "Studies of the morphological activity of rivers as illustrated by the river Fyris. [1]" in 1935. The graph ...
A riverscape [1] (also called river landscape) [2] comprises the features of the landscape which can be found on and along a river. Most features of riverscapes include natural landforms (such as meanders and oxbow lakes ) but they can also include artificial landforms (such as man-made levees and river groynes ).
Changes in the steepness of the stream gradient, the amount of sediment contained in the river, and the total amount of water flowing through the system, all influence how a river behaves. There is a delicate equilibrium that controls a river system, which, when disturbed, causes flooding and incising events to occur and produce terracing. [3] [4]
The Severn Bridges crossing near the mouth of the River Severn The River Thames in London The River Tay in Perth, by measured flow the largest in Great Britain. This is a list of the major rivers of the United Kingdom, as being prominent in length, flow volume (discharge rate), or both.
The dead zone at the outlet of the Mississippi River is a consequence of nitrates from fertilizer being carried off agricultural fields and funnelled down the river system to the Gulf of Mexico. Runoff also plays a part in the carbon cycle , again through the transport of eroded rock and soil.
GCSE Bitesize was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home.
The headwaters of a river are the smaller streams that feed a river, and make up the river's source. [4] These streams may be small and flow rapidly down the sides of mountains . [ 5 ] All of the land uphill of a river that feeds it with water in this way is in that river's drainage basin or watershed. [ 4 ]
