In recent years severe flooding has occurred in several parts of Europe, both as
localized flash floods and as basin-wide floods on major river systems. By their nature
floods are generated by the random coincidence of several meteorological factors, but
man's use of the river catchment also has an impact upon the severity and
consequences of the events. Flood forecasting systems have advanced to use the latest
developments in monitoring, communications and computing technology. However,
important issues remain in both the detailed understanding and simulation of processes
involved in flood propagation and also in the best practice for management of the river
and its catchment. European research on flood forecasting and climate change impacts
has been funded since 1986 and in 1995 the EC Directorate General of Research and
Development (DG XII) organised an expert workshop to discuss the state-of-the-art
and research needs in the area of river flood management. A working group was
established at the end of the workshop to draft out the content of a Concerted Action
in this area.
The RIBAMOD Concerted Action is funded by DG XII as a part of the Fourth
Framework Research programme. It examines long-term generic issues as initiatives
are already in place to tackle operational problems in specific river systems. The
Concerted Action focuses on flooding but considered within the framework of
integrated river management. The Concerted Action has five main objectives:
to identify difficulties arising from past management practices
toy state-of-the-art
to identify best practice
to take an overview of current EC research projects in the area, and
to identify research needs.
It is expected that other benefits will ensue from the RIBAMOD Concerted Action
• establishing an informal network of researchers and practitioners, and
• transfer of information, results and experience between existing research
programmes and practitioners. RIBAMOD will promote understanding of technical and policy issues in flood
management, will examine how advanced modelling should support planning, design,
operation and maintenance of flood defence systems and will identify methods and
procedures for sustainable development, management and use of the river and its
Four international meetings have been scheduled during the Concerted Action: two
Expert Meetings (by invitation) and two open Workshops. It is intended that
participants in these events will come from all the member states of the EU. The
location, date and theme of the four events is listed below.

Impacts of Climate Change on Flooding and Sustainable River Management
First RIBAMOD Workshop
In this volume, the proceedings of the first RIBAMOD Workshop are collected. The
theme of the workshop was 'Current policy and practice'. More specifically, the
following topics have been dealt with:
• understanding of the causes of recent floods across Europe
• identifications of lessons learned through case studies of different types of
catchment and basins
• comparison of standards; design, evaluation and decision procedures; and
experience of flood mitigation across Europe and its regions
• how flood risk is assessed, how it is changing and how the public understands
and tolerates flood risk
• review of past and current design methods and management
• strategies, their effects and the need for change
• identify EU Research and Technology Development needs.
The proceedings of the workshop comprise the papers presented. The various topics
will be introduced by means of keynote lectures and paper presentations. Abstracts of
the presentations have been collected in this volume.
