To improve the analysis of risk in areas protected by multiple defences for strategic planning and application of project appraisal guidance.
This report summarises the findings of the R&D project titled Risk Assessment of flood and coastal defence for Strategic Planning (RASP) funded through the Risk Evaluation Understanding of Uncertainty Theme of the joint EA/Defra research programme.
The RASP Project aims to develop and demonstrate methods for supporting Integrated Flood Risk Management. In particular, RASP provides a hierarchy of methodologies to support the assessment of flood risk at a range of scales (national, regional, local) and levels of detail. At each scale the RASP methods are focused on understanding the probability of flooding at a particular location within the floodplain taking account of the protection afforded by defences.
