Edwin Samuel Crump CIE (born 6 July 1882, died 5 March 1961) was an English civil engineer specialising in hydraulics.
Crump was born in Wolverhampton, Staffordshire, England, the youngest child of Charles Crump and Clara Annie Crump (nee Gittoes). [1] His father Charles Crump was Chief Clerk, Northern Division, Great Western Railway Company, prominent football legislator and administrator, and committed Methodist. [1] [2] Edwin Crump was educated as a civil engineer at the Department of Engineering, Imperial College. [3]
Crump married Helen Elizabeth Jefferis in 1913 and had two sons, Anthony Jefferis Crump (born 1914) and Colin Edwin Crump (born 1916).[ citation needed ]
Crump joined the Indian Service of Engineers in 1906 and was based in Punjab Province, British India. Here he was engaged in irrigation projects of the Punjab Water Station. During World War I Crump served as an engineer in South Africa. Crump retired from the Indian Service of Engineers in 1937. After returning to England, Crump joined in 1949 the newly established Hydraulics Research Station at Wallingford, Oxfordshire, part of the Hydraulic Research Organisation, Department of Scientific and Industrial Research. In 1952 he was promoted to Senior Scientific Officer, retiring in 1956. [4]
Crump was made Companion of the Indian Empire (CIE) at the King's Birthday Honours of 1936 for his work with the Indian Service of Engineers as Superintending Engineer, Public Works Department (Irrigation Branch), Punjab Province.
Edwin Samuel Crump was the inventor of the Crump weir that is named for him. The Crump weir is a two dimensional triangular weir with a horizontal crest in the transverse direction and a triangular crest shape in the stream-wise direction. Crump weirs are used as measuring structures in open channels. [5]
Crump published a number of seminal papers in the field of hydraulics, including methods to accurately measure stream flow by means of the Crump weir, [6] design of steeply graded pipelines, [7] and vortex-siphon spillways. [8] [9]
John Glen Wardrop (1922–1989), born in Warwick, England, was an English mathematician and transport analyst who developed what became known as Wardrop's first and second principles of equilibrium in the field of traffic assignment.
A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level.
A spillway is a structure used to provide the controlled release of water from a dam or levee downstream, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water.
In hydraulic engineering, a nappe is a sheet or curtain of water that flows over a weir or dam. The upper and lower water surface have well-defined characteristics that are created by the crest of a dam or weir. Both structures have different features that characterize how a nappe might flow through or over impervious concrete structures. Hydraulic engineers distinguish these two water structures in characterizing and calculating the formation of a nappe. Engineers account for the bathymetry of standing bodies or moving bodies of water. An appropriate crest is built for the dam or weir so that dam failure is not caused by nappe vibration or air cavitation from free-overall structures.
The M25 Runnymede Bridge is a motorway, A-road and pedestrian and cycle bridge, built in the 1960s and 1980s and expanded in the 2000s, carrying the M25 and A30 across the River Thames near the uppermost end of the Staines upon Thames and Egham reach of the river. It is oriented north–south and is southwest of Heathrow Airport. It consists of the Runnymede Bridge and the New Runnymede Bridge; commonly referred to as one bridge.
Ulley Reservoir is a reservoir a few hundred yards to the west and downhill of the village of Ulley, 4 miles (6.4 km) south of Rotherham, South Yorkshire, England. It is 2.5 miles (4 km) away from junction 33 of the M1 motorway.
The Telford Medal is a prize awarded by the British Institution of Civil Engineers (ICE) for a paper or series of papers. It was introduced in 1835 following a bequest made by Thomas Telford, the ICE's first president. It can be awarded in gold, silver or bronze; the Telford Gold Medal is the highest award the institution can bestow.
Hubert Chanson is a professional engineer and academic in hydraulic engineering and environmental fluid mechanics. Since 1990 he has worked at the University of Queensland.
Sir Norman Andrew Forster Rowntree was a British civil engineer.
John Anthony Derrington was a British civil engineer.
John Shillingford, of Exeter and Shillingford, Devon, was an English politician.
The New Year Honours 1893 were appointments by Queen Victoria to various orders and honours to reward and highlight good works by members of the British Empire. They were published on 2 January 1893.
The New Year Honours 1922 were appointments by King George V to various orders and honours to reward and highlight good works by members of the British Empire. They were published on 30 December 1921.
Lieutenant-General Sir Harold Williams was an Irish-born British Army officer, engineer and mountaineer. He also became charter president of Rotary club Roorkee in 1959.
Charles George Hawes CIE MC (1890–1963) was a British engineer, hydrologist and colonial administrator in the Indian Engineering Service. He became Chief Engineer and Secretary to the Government of Sind and also served with distinction in both World Wars.
The 1921 Birthday Honours were appointments by King George V to various orders and honours to reward and highlight good works by citizens of the British Empire. The appointments were made to celebrate the official birthday of the King, and were published on 3 and 4 June 1921.
Sir Robert John Mathieson Inglis (1881–1962) was a Scots-born railway engineer noted for his work in Britain and India and his reorganisation of the railways in post-war Germany.
The River Hull tidal surge barrier is a flood control gate located on the River Hull in the city of Kingston upon Hull, in the East Riding of Yorkshire, England. The barrier impounds the river in times of tidal surges, preventing water moving upstream of the river from the Humber Estuary, and flooding the areas of the city which are near to the river, or susceptible to flooding. It is held horizontal when not in use, and turns 90 degrees before being lowered to the riverbed in the event of a tidal surge. It is the second largest flood barrier in the United Kingdom after the Thames Barrier in London.
Sir Alfred Chatterton was a British civil servant and civil engineer who worked in India and served as the first director of industries for the Madras Presidency (1900-1908) and as director of industries and commerce in Mysore (1908-1912).
Bernard Patrick J. Wex OBE was an English civil engineer particularly associated with the design of bridges.
