What is IMPACT?
• A research programme supported by the European Commission under the fifth framework programme and contributing to the implementation of the Generic Activity on Natural and Technological Hazards within the Energy, Environment and Sustainable Development Programme
• A 3 year research programme - started Dec 2001; ends Nov 2004 (4th workshop, Zaragoza, Spain in Autumn)
• A Project comprising 11 partners from 10 countries
[See brochure and CD ROMS from workshops #1 and #2][www.impact-project.net]

IMPACTInvestigation of extreme flood Processes and uncertainty
The problem to be solved...
“The assessment and reduction of risks from extreme flooding caused by natural events or the failure of dams and flood defence structures”
(Structures = dams, weirs, sluices, flood embankments, dikes, tailings dams etc.)

IMPACTInvestigation of extreme flood Processes and uncertainty
The problem to be solved...
“To manage and minimise (flood) risks effectively it is necessary to be able to identify hazards and vulnerability in a consistent and reliable manner, to have good knowledge of structure behaviour in emergency situations, and to understand the potential consequences of failure in order to allow effective contingency planning for public safety”

IMPACTInvestigation of extreme flood Processes and uncertainty
Scientific Objectives & Approach
Generic approach is via a combination of:
• Fieldwork
• Laboratory physical modelling
• Desk analysis
• Computational modelling
including a focus upon assessment of process uncertainty in all areas

Benefits of the IMPACT Project
Ultimately a reduction in risk to the public through:
• improved understanding of extreme processes, hence improved understanding of associated risks to the public, environment, assets etc.
• improved reliability of modelling tools
• improved understanding of modelling results, leading to more appropriate application of predictions (e.g. emergency planning

Some Key Aspects of Implementation
The Overall Approach
• To keep a focus on overall objectives and application by end users
• To complement and benefit from other National & International R&D (interaction with additional organisations wherever possible)
• End user take up / application of results
