He has published extensively on catchment hydrology in several international journals and is Executive Editor of the European Geosciences Union's Hydrology and Earth System Sciences journal. Professor Sivapalan also received the European Geophysical Society's John Dalton Medal, the International Hydrology Prize of the IAHS, the Hydrological Sciences Award and Robert E. Horton Medal of the American Geophysical Union. He was also the recipient of the Centenary Medal of the Australian Government and an Honorary Doctorate of the Delft University of Technology. Thorsten Wagener is Professor of Water and Environmental Security in the Department of Civil Engineering at the University of Bristol. He is a Vice President of the International Association of Hydrological Sciences, Editor of Hydrology and Earth System Sciences, and associate editor of several other journals. Dr Wagener has been awarded DAAD (Deutscher Akademischer Austauschdienst) fellowships, the IEMSS Early Career Excellence Prize, Best Paper Awards of the Journal of Environmental Modeling and Software, the US EPA Early Career Award, the Walter Huber Civil Engineering Research Prize of the American Society of Civil Engineers, the Alexander von Humboldt Foundation Fellowship, and the Education and Public Service Award of the Universities Council for Water Resources. Alberto Viglione is a Research Hydrologist at the Vienna University of Technology. During 2004 to 2007 he conducted doctoral research on 'non-supervised statistical methods for the prediction of hydrological variables in ungauged sites' at the Hydraulic Department of the Politecnico of Turin. He has authored or co-authored numerous papers in hydrology, particularly on floods, both from statistical and process-based perspectives, and on hydrological characterisation of river basins. Dr Viglione has developed software for regional frequency analysis and rainfall-runoff modelling under the R environment, which is available online. He also acts as a reviewer for several prestigious journals and has been involved in a number of research projects related to hydrology and flood frequency analysis, in Italy, Austria and for European governments. Hubert Savenije is Professor of Hydrology and head of the Water Resources Section at the Delft University of Technology and also serves as Editor-in-Chief of Hydrology and Earth System Sciences and Physics and Chemistry of the Earth. He is President-Elect of IAHS as well as Chair of the IAHS Predictions in Ungauged Basins (PUB) initiative. Professor Savenije has published widely in several leading international journals and was Vice Rector at UNESCO-IHE, Institute for Water Education. He is Past-President of Hydrological Sciences of the European Geosciences Union (EGU) and Past-President of the International Commission on Water Resources Systems of the International Association of Hydrological Sciences (IAHS). He has been awarded, among other things, the Henry Darcy Medal of the European Geosciences Union and the EGU Batch Award.
