Willi H. Hager (born July 8, 1951) is a Swiss civil engineer and Professor at the ETH Zurich, Department of Civil, Environmental and Geomatic Engineering, [1] known for his work on hydraulics. [2] [3]

Civil engineer engineer specialising in design, construction and maintenance of the built environment

A civil engineer is a person who practices civil engineering – the application of planning, designing, constructing, maintaining, and operating infrastructures while protecting the public and environmental health, as well as improving existing infrastructures that have been neglected.

ETH Zurich Swiss Federal Institute of Technology in Zurich

ETH Zurich is a science, technology, engineering and mathematics university in the city of Zürich, Switzerland. Like its sister institution EPFL, it is an integral part of the Swiss Federal Institutes of Technology Domain that is directly subordinate to Switzerland's Federal Department of Economic Affairs, Education and Research. The school was founded by the Swiss Federal Government in 1854 with the stated mission to educate engineers and scientists, serve as a national center of excellence in science and technology and provide a hub for interaction between the scientific community and industry.

Hydraulics liquid engineering

Hydraulics is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. Free surface hydraulics is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, estuaries and seas. Its sub-field open-channel flow studies the flow in open channels.

Biography

Born in 1951, Hager obtained his engineering degree from the ETH Zurich in 1976, were in 1981 he also obtained his PhD at its VAW Laboratory of Hydraulics, Hydrology and Glaciology. [1]

Hager had started his career in industry in engineering. In 1981 he joined the Swiss Federal Institute of Lausanne (EPFL), where he was appointed scientific collaborator of Chair of Hydraulic Constructions. In 1989 he returned to the ETH Zurich, where he was appointed Professor and chaired the scientific staff of the VAW Laboratory of Hydraulics, Hydrology and Glaciology. [1]

Among others in 1988 Hager received the J.C. Stevens Award by the American Society of Civil Engineers, and in 1997 he received the Ippen Award by the International Association for Hydraulic Research (IAHR). [1]

American Society of Civil Engineers professional association

The American Society of Civil Engineers (ASCE) is a tax-exempt professional body founded in 1852 to represent members of the civil engineering profession worldwide. Headquartered in Reston, Virginia, it is the oldest national engineering society in the United States. Its constitution was based on the older Boston Society of Civil Engineers from 1848.

Hydrology The science of the movement, distribution, and quality of water on Earth and other planets

Hydrology is the scientific study of the movement, distribution, and quality of water on Earth and other planets, including the water cycle, water resources and environmental watershed sustainability. A practitioner of hydrology is a hydrologist, working within the fields of earth or environmental science, physical geography, geology or civil and environmental engineering. Using various analytical methods and scientific techniques, they collect and analyze data to help solve water related problems such as environmental preservation, natural disasters, and water management.

Aletsch Glacier glacier in Switzerland

The Aletsch Glacier or Great Aletsch Glacier is the largest glacier in the Alps. It has a length of about 23 km (14 mi) (2014), has about a volume of 15.4 km3 (3.7 cu mi) (2011), and covers about 81.7 km2 (2011) in the eastern Bernese Alps in the Swiss canton of Valais. The Aletsch Glacier is composed of four smaller glaciers converging at Concordia Place, where its thickness was measured by the ETH to be still near 1 km (3,300 ft). It then continues towards the Rhône valley before giving birth to the Massa. The Aletsch Glacier is – like most glaciers on this world – a retreating glacier. As of 2016, since 1980 it lost 1.3 kilometres (0.81 mi) of its length, since 1870 3.2 kilometres (2.0 mi), and lost also more than 300 metres (980 ft) of its thickness.

Lino Guzzella, born in 1957, is a binational professor at the Swiss Federal Institute of Technology in Zurich, Switzerland.

Hubert Chanson is a professor in hydraulic engineering and applied fluid mechanics in the School of Civil Engineering at the University of Queensland since 1990. He lectures civil and environmental engineering students in a variety of courses including fluid mechanics, hydraulic engineering, civil design, engineering history, coastal processes and environmental modelling. His research interests include the hydraulics of open channel flow, the design of hydraulic structures, experimental investigations of two-phase flows, coastal and estuarine hydrodynamics, water quality modelling, environmental management and natural resources.

The Institute of Robotics and Intelligent Systems (IRIS) is part of the ETH Zurich, Switzerland. It replaced the existing Institute of Robotics, of the ETH Zurich in October 2002, when Prof. Bradley J. Nelson moved from the University of Minnesota, United States, to ETH Zurich and succeeded the Prof. Dr. Gerhard Schweitzer.

The Hydraulics Research Station (HRS) was created by the UK Department of Scientific and Industrial Research in 1947. The Research Station was based in Wallingford, near Oxford. It was established to deal with “looser boundary” problems such as coastal erosion, flood protection and the silting and scouring of rivers, estuaries and harbours. The Hydraulics Research Station was housed at Howbery Park as a government establishment until 1982, when it was privatised from the Department of the Environment (DoE) to become Hydraulics Research Station Limited. It is now known as HR Wallingford. During its existence, HRS contributed to advance hydraulics research. It also worked on water-related projects in the UK and around the world.
