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 (née 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. [5] 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. [6] Crump weirs are used as measuring structures in open channels. [7]
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, [5] design of steeply graded pipelines, [8] and vortex-siphon spillways. [9] [10]
Edwin Samuel Crump died at his home Blenheim House, Benson, Oxfordshire, on 5 March 1961.
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. There is no single definition as to what constitutes a weir.
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, 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.
Sir Hugh Eyre Campbell Beaver, KBE was an English-South African civil engineer, industrialist and bureaucrat, who founded the Guinness World Records. He was Director-General of the Ministry of Works and managing director at Guinness Brewery.
Lamaload Reservoir is a reservoir near Rainow, Cheshire, England. It lies in the South West Peak within the Peak District National Park, to the west of the Goyt Valley, and is fed by the River Dean. The reservoir is 0.93 km × 0.53 km, with a capacity of 1,909,000 m³, impounded by a multiple-arch, round-headed buttress dam in concrete, whose design was innovative at the time. It was built by Richard Costain Ltd in 1959–63 to serve Macclesfield, which lies to its west, and officially opened in 1965. The reservoir and associated water treatment works are owned by United Utilities. The area is a popular tourist spot, forming an access point for walkers to the surrounding moorland.
A buttress dam or hollow dam is a dam with a solid, water-tight upstream side that is supported at intervals on the downstream side by a series of buttresses or supports. The dam wall may be straight or curved. Most buttress dams are made of reinforced concrete and are heavy, pushing the dam into the ground. Water pushes against the dam, but the buttresses are inflexible and prevent the dam from falling over.
Runnymede Bridge is a motorway, A-road, 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 Runnymede Bridge and 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.
Johannes Aleidis (Johan) Ringers was a Dutch hydraulic engineer and politician. He served as the director-general of Rijkswaterstaat and later as the director of Dutch East Indies Railways. During World War II, Ringers was appointed as the government commissioner for reconstruction, but was later interned by German forces.

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.
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).
Shizuo Ishiguro (1920–2007) was a Japanese oceanographer who studied the dynamics of ocean waves using analog computing. He worked at the Nagasaki Marine Observatory from 1948 to 1960 receiving his doctorate from the University of Tokyo in 1958. His focus was large water oscillations known as “abiki” which occasionally cause ocean flooding in Nagasaki Bay. In 1957, Ishiguro was awarded a UNESCO fellowship to join the UK National Institute of Oceanography to adapt his work for storm surges in the North Sea, such as the serious flood of 1953.
The Ishiguro Storm Surge Machine is an analogue computer built by Japanese oceanographer Shizuo Ishiguro. Between 1960 and 1983, it was used to model storm surges in the North Sea by the UK National Institute of Oceanography. It is now on display in the Mathematics Gallery of the Science Museum in London.
