In July 2015 Attilio Castellarin joined Demetris Koutsoyiannis and Mike Acreman as co-editor of Hydrological Sciences Journal.

Welcome, Attilio, as HSJ Co-Editor by Demetris Koutsoyiannis.

The IAHS Bureau in Gothenburg (July 2013) agreed to gradually renew the panel of the Co-Editors of Hydrological Sciences Journal (HSJ) and increase their number from two (Zbyszek Kundzewicz and Demetris Koutsoyiannis), to three. Since April 2014, Mike Acreman was appointed as new Co-Editor, while in April 2015 Zbyszek Kundzewicz retired, after 18 years of leading HSJ.

The IAHS Bureau in Prague (June 2015) unanimously accepted an earlier proposal by the IAHS Ltd Board meeting (February 2015) that the new HSJ Co-Editor, who would replace Zbyszek, would be Attilio Castellarin.

Attilio is Associate Professor of Water Engineering and Hydrology at the University of Bologna. He received his Bachelor and Master’s Degree in Civil Engineering (major in Environmental Engineering) with honours in 1996 from the University of Bologna and his PhD in Water Engineering in 2001 from the Polytechnic of Milan. Since 2006 he teaches Hydraulic Infrastructures, Hydrological Modelling, and Water Resources Engineering and Management to undergraduate and graduate students of the School of Engineering and Architecture at the University of Bologna. He collaborates with UNESCO/IHE, USGS, TUW (Austria) and Tufts University (USA) within their training and scientific research programmes. He is author and co-author of 45 papers on journals indexed in WoS and Scopus. His research interests include hydrological applications for environmental and civil engineering: analysis of extreme hydrological events; hydrological predictions in ungauged watersheds; sustainable water resources management; anthropogenic and climate variability effects on hydrological processes; one- and two-dimensional hydraulic modelling; flood-hazard and flood-risk assessment and mapping. He has served on the Editorial Boards of the Journal of Hydrology (winner of the Associate Editor award in 2013) and Water Resources Research. He has also been a very active and responsible reviewer of HSJ.

Attilio’s scientific and teaching achievements, his successful editorial career and good reputation in other, top quality hydrological journals, as well as his enthusiastic acceptance of the HSJ Co-Editor position, accompanied with full and unreserved commitment to HSJ, are the first signs of a bright future in our collaboration and in leadership of the journal. His young age signifies the IAHS policy to engage the young generation of hydrologists into its activities, a policy also manifest in its new decade-long “Panta Rhei” initiative.

I have no doubt that the three Co-Editors together will achieve much for the benefit of HSJ and the international hydrological community.

Welcome, Attilio as HJS Co-Editor and good luck in your new capacity.
