The 9th ICSE(Taipei, Taiwan, 5-8 November 2018) provides a platform to exchange ideas and share advances in research and practice on the scientific and engineering challenges related to scour and erosion. The 9th International Conference on Scour and Erosion will take place in Taipei, Taiwan from 5-8 November 2018. The conference provides a platform for scientists and engineers from around the world to exchange ideas and share advances in research and practice on the scientific and engineering challenges related to scour and erosion. The broad topics covered in ICSE conferences include fundamental mechanisms of erosion and scour, modelling (both physical and numerical) of erosion and scour processes and engineering applications that involve scour and erosion processes. The ICSE conferences have been well attended by scientists and engineers from broad areas such as civil engineering, hydraulic engineering, coastal and offshore engineering. One of the strong features of the ICSE conferences has been the cross disciplinary collaborations between geotechnical and hydraulic engineers. The ICSE conference series was initiated by the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) in 2002 and is currently run by the Technical Committee TC213 (Scour and Erosion). National Chiao Tung University is delighted to be organizing ICSE 2018 on behalf of TC213.
