Hydrological change is one of the most importante research issues in modern hydrology. The emergence of unprecedented patterns in water related environmental processes has been reported in several recent contributions, thus pointing out how relevant changes are affecting the fundamental hydrological dynamics. Water plays a central role for societal systems and therefore any change affecting water security, and water related risks in general, is a matter of concern for society. However, hydrological change is still "a well known unknown". On the one hand, humans are well aware that environmental systems are continuously changing. On the other hand, natural variability and the associated change are poorly known. As a matter of fact, a systematic theoretical framework for dealing with hydrological change is still lacking.

The awareness of the above research challanges is the reason why the International Association of Hydrological Sciences has decided to focus on "Change in hydrology and Society" during the scientific decade 2013-2022, by launching the Pantha Rhei research initiative. To address the challanges of societal and environmental change and deepen the knowledge of in-beteen hydrological systems, Pantha Rhei aims to promote frontier scientific research with a joint effort of the worldwide hydrologic community.

This talk will focus on ideas for the development of a theoretical framework to support the interpretation of modelling of hydrological change, therefore contributing to Pantha Rhei targets. An overview of the foremost available approaches to deal with hydrological change will be presented to better clarify how to

  1. comprehend the changing behavior of hydrological systems,
  2. improve our capability to support hydrological design,
  3. and finally provide a satisfactory reply to the urgent societal issues related to water and environmental risks.
