Abstract:This report derives a methodology which combines spatial multi criteria analysis with risk assessment in order to support decision making for sustainable flood risk management of coastal zones. A trade-off is made between the reduction of tangible and intangible damage and the conservation of commodity (CO) and non-commodity output (NCO), for risk management strategies. In this case these strategies are land use changes. This is a trade-off between risk and benefit, where a reduction of risk often implies a reduction of benefit. This trade-off is often influenced by the perception of risk, which influences the preference for one of the opposing interests. Flood risk management policy scenarios are judged on the criteria, reduction of tangible and intangible damage and conservation of COs and NCOs in a spatial multi criteria analysis. Worry, awareness and preparedness, three parameters for risk perception are used to determine the weighting of the first two criteria versus the last two. Afterwards pairwise comparison can be used to fine tune the weighting. The methodology should guide a policy maker toward sustainable flood risk management but not make the decision for the best flood risk management policy alternative itself.
