Early life and education

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]

Personal life

Crump married Helen Elizabeth Jefferis in 1913 and had two sons, Anthony Jefferis Crump (born 1914) and Colin Edwin Crump (born 1916).[ citation needed ]

Career and accomplishments

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]

Honors and recognition

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]

Publications

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]

Weir Artificial river barrier

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.

Spillway Structure for controlled release of flows from a dam or levee

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.

M25 Runnymede Bridge

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 Reservoir in South Yorkshire, England

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.

Telford Medal

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.

River Hull tidal surge barrier A flood barrier in Kingston upon Hull, England

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.
