The key output from this project was a sensitivity analysis of the RASP HLM+ Risk Assessment of Flood and Coastal Defence for Strategic Planning (RASP) High Level Method Plus (HLM+) approach as applied within National Flood Risk Assessment (NaFRA) 2005. The project aimed to establish the relative contribution of different input data sets to the variability in the RASP HLM+ outputs. The project pointed the way to a rational approach to the value of data quality and model accuracy.
