Hydrology Research Special Issue on

Innovations, Advances and Future Challenges for the Hydrological Community



In the last decades, the hydrology and water management sectors have been dealing with global changes, proposing several innovative solutions. Climate changes are leading to an increase of long hot and dry periods, alternated by short and intense rainfall events. Urban areas are particularly vulnerable to these changes: the rapid population growth and the intense anthropic activity enhance the risk of extreme hydrological events. Several solutions have been proposed in the last years to monitor, prevent, forecast and mitigate rainfall extremes and their effects in natural and urban environments. Some questions, however, remain unsolved and new issues are challenging the hydrological community.

The 10th edition of the ‘Hydrology Days’ of the Italian Hydrological Society (SII-IHS) was held in Bologna (Italy) from 16 to 19 September 2019. During this event, hydrologists and stakeholders in the field of water resources management shared the results of their research and discussed the most relevant challenges that the hydrological community must face nowadays. With the celebration of the 10th anniversary, the SII-IHS promoted a Special Issue of Hydrology Research open to the participants of the ‘Hydrology Days’ as well as to other contributions related to the role of the hydrologist in a changing environment and the consequent challenges posed to the hydrological community.

The papers in this Special Issue reflect inter- and multidisciplinary aims and topics discussed during the ‘Hydrology Days’ of the SII-IHS. The contributions collected in this Special Issue are organized into the following three main topics: (1) Climate change and geo-hydrological risk, (2) Tools and techniques for improving the comprehension of catchment hydrology and river hydraulics, and (3) Sustainable use of water resources.
