Process-based flood damage modelling relying on expert knowledge: a methodological contribution applied to the agricultural sector

Abstract. Flood damage assessment is crucial for evaluating flood management policies. In particular, properly assessing to agricultural assets important because they are complex economic systems particularly exposed floods. The modelling approaches used assess of several types and can be fed by data collected post-flood, from experiments or based on expert knowledge. process-based models knowledge the subject research also widely in an operational way. Although identified as potentially transferable, reality often case-specific difficult reuse time (updatability) space (transferability). this paper, we argue that models, a rigorous process, suitable application different contexts. We propose methodological framework aimed at verifying conditions necessary develop these spirit capitalisation relying four axes which (i) explicitation assumptions, (ii) validation, (iii) updatability, (iv) transferability. then applied model have developed France produce national functions sector. show paper proposed facilitates explicit description assumptions used, consider transfer another geographical area. sense, constitutes solid basis considering transfer, comparison around processes conclusion, identify tracks implemented so pursue improvement international cooperation.
