STAHY OFFICIAL WOKSHOP

Advances in Statistical Hydrology

Taormina (Sicily), Italy
May 23-25, 2010

The workshop involved 28 oral contributions and 30 posters and was attended by 80 people from 24 countries.

Two really interesting invited lectures were held by prof. Vijay Singh and Prof. Jose D. Salas on entropy theory and long memory linear modeling.

Particularly interesting was the round table, managed by prof. G. Rossi, in memory of Prof. V. Yevjevich. Many colleagues gave their contribution either about the extraordinary life and about the research activity of this father of hydrology.

All the participants delivered interesting presentations underlined by a rich discussion.

Following the oral session a discussion was stimulated with the aim to identify future topics to potentially include in the STAHY initiatives. Among others it was clear that it could be useful to include in the next initiatives:

time series analysis, long range dependence, linear and non linear modelling, uncertainty analysis, regionalization procedures.

 

A special thanks to the University of Catania, Department of Civil and Environmental Engineering for the wonderful organization and warm hospitality, in particular to:

Antonino Cancelliere, Giuseppe Rossi, David J. Peres, Antonio Castano, Sandra Lazzarini, Leila Castiglione, Brunella Bonaccorso and Vincenzo Nicolosi.

Thanks also to the Science4.tv (CNR - Ufficio Pubblicazioni ed Informazioni Scientifiche: www.science4.tv; www.cnr.it) that hosts the video collection of the workshop.
