REPORT of STAHY-WG Workshop at IAHS Scientific Assembly

The STAHY Working group organized the workshop WH7 “New Statistics in Hydrology” coordinated by Salvatore Grimaldi, Demetris Koutsoyiannis and George Kuczera.
The workshop involved 9 oral contributions and 1 poster (listed at the end of the report) and was attended by 60 people.
All the authors delivered interesting presentations underlined by a rich discussion.
Of particular interest was the invited lecture given by Prof Hoshin Gupta. An insightful presentation on Bayesian analysis for model identification was given leading to good discussion on the future development of this approach.
Other interesting contributions were given by Prof. Taha Ouarda on copula function application in regionalization analyses and by Prof. Andras Bardossy who proposed the innovative depth function concept in the hydrological modeling calibration to identify the parameter space border.
During the week there were many occasions to share new ideas with the STAHY members present at the Scientific Assembly.
