Roger Falconer was elected a Fellow of the Royal Academy of Engineering in 1997, Fellow of the City and Guilds Institute of London in 1997 and Fellow of the Learned Society of Wales in 2011. He was elected President (2011-15) and Honorary Member (2017) of the International Association for Hydro-Environment Engineer and Research and is currently a Member of the Board of Trustees for the Chartered Institution of Water and Environmental Management. He was Chair of the Civil and Construction Engineering Sub-Panel for the 2014 Research Excellence Framework REF2014 and was a member of the Civil Engineering Sub-Panel for the 2008 Research Assessment Exercise RAE2008.
Prior to joining Cardiff University, he was a Lecturer in Hydraulic Engineering at the University of Birmingham (1977-86), and Professor of Water Engineering (1987-97) and Head of the Department of Civil Engineering (1993-97) at the University of Bradford. He also holds Honorary Professor appointments at the universities of Tianjin (China), Tongji (China), Sichuan University (China), and the Institute of Water Resources and Hydropower Research, Beijing, and Hong Kong Polytechnic University.
At Cardiff his research has continued in the development, refinement and application of computer models for predicting hydrodynamic, water quality and sediment transport processes in coastal, estuarine and inland waters. He has developed three widely used computational hydro-environmental models, namely FASTER, DIVAST and TRIVAST for predicting 1D, 2D and 3D hydrodynamic, pollutant and sediment transport processes in marine and aquatic basins. He has also developed CONTANK for predicting disinfection processes in water supply tanks. These models have been acquired by consulting companies and government organisations, for application to over 100 hydro-environmental impact assessment studies worldwide, and by over 60 academic institutions in 18 countries for research studies. He has worked closely with CH2M (previously Halcrow) in developing ISIS-2D, a computer model used for predicting two-dimensional flood water elevations and inundation extent across floodplains. His more recent research activities have extended to renewable tidal energy devices and structures and global water security. In particular, he has undertaken extensive work on the hydro-environmental impact of a barrage across the Severn Estuary and various lagoons.
He has edited 7 books, published over 450 papers in refereed journals and international conference proceedings and over 80 technical reports; leading to a Scopus h-index of 34 and over 3600 citations (Google Scholar: h-index of 49 and over 6900 citations). He is, or has been, a member of the editorial board of several key leading international journals in his field and co-founded the Journal of Hydroinformatics, the International Journal of River basin Management, the ICE Journal of Water Management and the Journal of Applied Water Engineering and Research. He has delivered over 30 keynote or plenary lectures at international conferences world-wide and has given lectures on his research to over 500 institutions or learned society meetings in 21 countries. He has also delivered a number of prestigious lectures including for example: the International Association for Hydraulic Research (IAHR) Ippen Lecture, Madrid (1991), the Institution of Civil Engineers Vernon Harcourt Lecture (1992) and the Dugald Clerk lecture (2015), the European Dredging Association 10th Anniversary Lecture, Brussels (2003), the 35th Idris Jones Memorial Lecture, Cardiff (2008), the Royal Academy of Engineering lectures on the Severn Barrage (2007) and Global Water Security (2008), and the Parliamentary and Scientific Society (2010). He has supervised over 50 PhD students to completion, acted as External Examiner for PhD candidates at over 40 universities worldwide and acted as External Examiner for undergraduate and postgraduate courses in the UK and overseas including: the University of Hong Kong and Malaya. He has wide international links and has served on the scientific advisory committee of over 100 international conferences.
He has also participated extensively in TV, Radio and Press interviews, on a wide range of professional topics and projects; most notably the Severn Barrage, river and coastal flooding, bridge scour and global water security. He has entries in Who's Who and Debrett's People of Today. He regularly advises government agencies and international organisations on a range of water management and engineering issues and was a member of the UK Government’s ‘Expert Panel’ for the Severn Tidal Power Studies (2008-10), the ASCE Task Force on Tidal Wetlands and the International Law of the Sea Tribunal’s ‘Group of Experts’ in the Malaysia v. Singapore Land Reclamation Case (2004-05).
