  • Funders: EPSRC Grant: EP/FP202511/1 www.floodrisk.org.uk The implication of this is that scientific uncertainty is an relatively unwelcome part of the risk message they are charged with translating for the public PROFESSIONALS experience BINARY DECISION UNCERTAINTY (Decision rule uncertainty) BARRIERS? SCIENTIFIC UNCERTAINTY Uncertainty in the science of flood forecasting and runoff prediction models are largely associated with their assumptions, structure, and boundary conditions, and confidence in validation procedures given uncertainties about climatic and societal futures SCIENTIFIC AND DECISION MAKERS DIFFER IN THEIR UNDERSTANDING OF THE SOURCES OF UNCERTAINTY

  • Funders: EPSRC Grant: EP/FP202511/1 www.floodrisk.org.uk THE LANGUAGE OF SCIENCE IS OPAQUE TO THE NON-SCIENTIFIC PROFESSIONAL BARRIERS? If originally formulated in Bayesian terms, the language may be too opaque for translation to be effective do professionals have sufficient statistical familiarity? Bayesian statistics ? Bayesian statistics ? Prior probability distributions? Prior probability distributions? fuzzy set methods ? fuzzy set methods ? info-gap methods ? info-gap methods ? NUSAP? NUSAP? match tool to communication interface match tool to communication interface The implication of this is that the language used to communicate the uncertainty must match the needs and agenda of the agencies involved in the communication being undertaken

  • Funders: EPSRC Grant: EP/FP202511/1 www.floodrisk.org.uk Our research (Faulkner et al 2007;McCarthy et al. 2009), both the interviews undertaken with professionals and from the experiment undertaken at the co-location workshop in Exeter, found that : The power of VISUALISATIONS AND ANIMATIONS in realising the uncertainty estimates was potentially great; The professionals questioned initially struggled to comprehend scientifically defined flood forecast uncertainties (probabilistic and/or ensemble forecasts) without FURTHER TRANSLATION OF THE SCIENCE. When this was available as perhaps a translational discourse, the preparedness to embrace a more sophisticated expression of the models uncertainties was welcomed. Better DECISION-SUPPORT TOOLS are needed. FINDINGS FINDINGS

COUCHED in : Mutually exchanged and agreed languages and professional context; EMBRACES: A decision about the modelling strategy to be adopted for a particular type of application, any decision about which uncertainties should be modelled should also be made by joint exchanges within the translational discourse.
