IAHS - Panta Rhei
Change in Hydrology and Society

Session "4.II - Adaptation to changing flood risk" at the European Climate Change Adaptation conference, 12th to 14th of May, 2015, in Copenhagen
The session is organised by the Panta Rhei Working group “Changes in flood risk” chaired by Heidi Kreibich and Sergiy Vorogushyn.
Abstracts can be submitted by following the appropriate link at the conference website. The deadline for abstract submission is 1st of February, 2015.
Flood damage has been increasing globally and in Europe during recent decades, which is assumed to be mainly related to socio-economic factors, such as accumulation of assets and increasing susceptibility in flood-prone areas. However, other factors play a role as well, such as climate change and human interventions in river systems and catchments.

The Fall Meeting of the American Geophysical Union ( http://fallmeeting.agu.org/2014/) proposed several events that are relevant to Panta Rhei.
First of all, session H34E was explicitly dedicated to Panta Rhei, which was titled "Sociohydrology: Modeling Feedbacks in Complex Coupled Natural Human Water Systems (Panta Rhei - Everything Flows)". Oral talks were delivered by Alberto Montanari (Chair of Panta Rhei), Richard Vogel, Charles J Vorosmarty, Christopher A Scott, Veena Srinivasan, Juan Carlos Castilla Rho, and Rachata Muneepeerakul. Furthermore, Hubert Savenije, President of IAHS, delivered an oral talk in session H41L, titled "Water Footprint Assessment and the Panta Rhei research initiative of the International Association of Hydrological Sciences (IAHS)".
Furthermore, it is my pleasure to report that Hubert Savenije was also awarded withe the Fellowship of the American Geophysical Union and Demetris Koutosyiannis, Editor of the Hydrological Sciences Journal, was awarded with the Lorenz Lecture. The video of his lecture is available here (free access for AGU members only).
Overall, is has been a very stimulating meeting that brought a lot of visibility to Panta Rhei.

Panta Rhei is represented by several sessions at EGU2015. We would like to
thank very much the Working Groups (WG) that actively proposed several symposia.
The list of the EGU2015 session organized by the WGs is reported here below.

A new working group has been approved into Panta Rhei, titled: "Water scarcity assessment: methodology and application". The working group is chaired by Prof. Junguo Liu, School of Nature Conservation, Beijing Forestry University, Beijing, 10083, China. The programme of the working group can be downloaded here.

This workshop is co-sponsored by EGU, and Deltares, and is part of the Panta Rhei working group activities of the IAHS
9/10 December 2014, Deltares, Delft, The Netherlands
Please submit abstracts (limited to 500 words) by 15 October 2014 to: EGUworkshop@deltares.nl
Flood risk analysis, which is used to make important and often expensive decisions, is complex and subject to significant uncertainty. The fact that this information is important but also uncertain has led to an increasing requirement to verify and validate flood risk analyses.
In this workshop we aim to gain an overview of validation and verification methods for models used in flood risk analysis \u2013 specifically for models of processes for which only limited observations are available (e.g., levee
failure, inundation, and flood impacts). In these cases, traditional validation techniques that require a lot of data are not applicable.
This workshop will bring together international experts on flood hazard estimation and risk assessment, working on fluvial, pluvial, coastal, and flash floods. The goal is to critically discuss to what extent current approaches and models are able to accurately estimate hazard, failure, exposure, and vulnerability \u2013 in sum: flood risk. The workshop will provide a platform to share best practices to validate and evaluate flood risk models.
