Maison des Sciences de l’Homme-Alpes, 1221 avenue Centrale, Domaine Universitaire, 38400 Saint Martin d’Hères, France.

Workshop aims

The Cross community workshop on past flood variability aims to:

- gather scientists from different archive communities and promote collaboration
- discuss archive-specific methodological aspects
- discuss advantages/challenges/limitations of each archive and exchange experiences
- intensify work on database
- define and discuss goals, products and timelines for the coming year and the complete first three-year period of the Floods Working Group.

Sessions and discussion topics

The following sessions and discussion topics are being prepared:

Session I: What archives can be used to reconstruct past flood variability?
Session II: How to develop a multi-archive approach?
Session III: How to proceed from paleo-flood data sets to statistical analysis, hydro-climate modelling and flood-hazard assessment?

Archive-specific group discussions:
i) Discuss the potential of and the interest in archive-specific review papers in the frame of a post-conference special journal issue.
ii) Discuss the ‘ideal’ data format (required fields) for a paleo-flood database.

Plenary discussions:
I. Summary of group discussions
II. How to proceed with the collection of data and the database
III. Goals, products and timelines for the first 3-year period of the working group.
