Jørgen Fredsøe is a hydraulic engineer born in Randers, Denmark 1947.
Academic life
editHe has a M.Sc. in 1971 and a Ph.D. in Civil Engineering in 1974, Technical University of Denmark. In 1984 he got the Dr. Tech. title with the Thesis: Sediment Transport in Currents and Waves, also at the Technical University of Denmark. He joined the faculty in Civil Engineering from 1974, and became a full professor in 1985. In 1979 he was visiting researcher at Iowa Institute of Hydraulic Research, Iowa City, USA.[1][2][3]
Awards
editCoastal Dynamic Award, 2005. Karl Emil Hilgard Prize (best paper awards, ASCE: American Society Civil Engineers), 1992 and 2005.
Research
editThe research covers six main topics:
- River Morphology (bed forms[4][5][6][7], meandering/braiding[8]) and sedimentation of navigation channels[9][10][11].
- Sediment transport i flowing water and in combined waves and current (the coastal zone)[12][13][14][15].
- Coastal morphology: Dynamics of bars, longshore undulations; long- and cross shore sediment transport in coastal zones[16][17][18][19].
- Wave boundary layers[20][21][22][23][24].
- Erosion around offshore structures[25][26][27][28].
- Forces on and vibration of offshore structures such as pipelines and wind turbine towers[29][30][31][32][33].

Other
edit- Member of the Council, the Danish Academy of Technical Sciences (ATV) 1996-2000.
- Institute Director ISVA, DTU (Technical University of Denmark) 1996-2000.
- Next to his university job, he worked as a consultant for many Danish Consulting companies, especially DHI and LICengineering Ltd both specialized in Hydraulic Engineering. In addition he has worked for the Danish Coastal Authority, for the World Bank (China and Bangladesh) and for public authorities in US, Ireland and Iceland. Latest he had a two-year employment 2017-2020 in India (related to Indus, Ganges and Brahmaputra rivers).
