Evaluating targeted heuristics for vulnerability assessment in flood impact model chains

Abstract In flood risk management, the choice of vulnerability functions has a remarkable impact on the overall uncertainty of modelling flood damage. The spatial transferability of empirical vulnerability functions is limited, leading to the need for computation and validation of region‐specific vu...
