First STAHY Workshop

The Workshop, included in the Symposium “The role of hydrology in water resource management“, was characterized by 15 oral contributions and 21 posters (listed at the end of the report).
Each contribution had available 20 minutes while poster contributions had 3 minutes of oral introduction.
All the authors showed interesting presentations underlined by a rich discussion.
Among several topics, particularly interesting appeared to be the speculation on climate change where Demetris Koutsoyiannis explained the critical role of statistical approaches that should be used in identifying the stationarity of the series and the long persistence.  His suggestion to apply non-static statistics (Kolmogorov-Hurst-Statistics) to analyze possible effects of climate change on meteorological and hydrological time series seems to be of great importance for the ongoing discussions in this field. The many facets of hydrological applications of statistics and the innovative character of hydrological research in this field became especially evident in two contributions: Simon-Michael Papalexiou introduced a new distribution for IDF curves and Alberto Montanari described the uncertainty of hydrological forecasting proposing a procedure to identify the distribution of errors. Many other presenters showed interesting applications using e.g. copula functions and others sophisticated methods. The applications were dedicated to regionalization, inference procedures on distribution functions useful for hydrological applications, multifractal measures, bayesian and bootstrap approaches.

A video with the presentation of the first day and some picture of the oral session of the second day are available on the following links:

At the end of the workshop was planned a meeting in order to fix details of future activities of the working group.
Among participants (around 25) there were the following IAHS bureau officers:
Andreas Schumann, Demetris Koutsoyiannis and Salvatore Grimaldi
During the meeting were approved the following initiatives:

- Short course “Copula Function: Theory and practice” Columbia University, Polytechnic Institute of New York Universities, New York City,  July, 18-25 2009;

- next official STAHY Workshop that will be held in May 2009 in Catania organized by Antonio Cancelliere;

- to include in the STAHY website activities the following topics identifying also some people responsible for collecting materials:
Copula (Salvatore Grimaldi, Francesco Serinaldi, Tomas Bacigal, Emna Gargouri)
Time Series Linear Modelling (Marcella Corduas, Antonio Cancelliere)
Distibution Function  (Francesco Laio, Ronald van Nooijen, Alla Kolechkina Mauro Naghettini, Iwona Markiewicz, Valerio Noto).

All people present the meeting gave their availability to help the Working Group in the webportal creation.
All people present at meeting hope also that other scientists that have already given their availability to the Working Group, but not present in Capri, will actively contribute to STAHY activities proposed and approve during the meeting.
