“…Therefore, vulnerability modeling is of paramount importance and its evaluation is a key step in the chain of flood risk assessment since it links flood hazard to exposure metrics providing an estimate of the expected damage and loss. So far, vulnerability was mainly explored with studies on the assessment of direct potential damage to structures (Armanini et al, 2011;Jakob et al, 2012;Mazzorana et al, 2014), people (e.g., Milanesi et al, 2015Milanesi et al, , 2016Xia et al, 2014), network infrastructures (e.g., Serre et al, 2011), and vehicles (e.g., Arrighi et al, 2015;(e.g., Martínez-Gomariz et al, 2016).…”

Urban and land use planning is conditioned by flood risk analyses and is a great research challenge. While methods are available for quantitative hazard and risk modeling, there is still a major gap related to reliable rational approaches for vulnerability assessment. This is particularly true for assessing vulnerability of buildings to floods. This vulnerability, which is important for economic reasons as well as for the safety of individuals and communities, is usually conceptualized on an empirical basis. Such empirical approaches, however, are plagued by considerable uncertainties, mostly because the damage‐causing mechanisms on the building envelope are poorly represented. In order to advance this area, this paper focuses on the structural vulnerability of traditional masonry buildings in alpine areas exposed to flash floods. A simplified physically based conceptual model which requires a limited amount of input data is proposed. The resistance of a wall impacted by a flash flood is studied in a limit analysis framework, considering different geometric ratios and building configurations. The resulting stability thresholds, expressed in dimensionless form as a function of the water depth, were positively compared with the results provided by numerical finite element models of the investigated geometries. The application of the proposed vulnerability model in risk mitigation strategies provides reliable information, suitable for a first‐level risk assessment on large building stocks.

“…Even with this change in concept, a lack of appreciation of the nonstationarity of drivers and the complex system dynamics particularly under the influence of climate and socio-economic changes meant that conventional flood risk assessments were frequently misunderstood as providing a false sense of ''full safety'' (Milly et al 2008). Another limitation has been the lack of socio-economic concepts and methodologies to account for secondary economic consequences, such as long-term disruptions to economic chains (ripple effects, Serre et al 2011). Lack of understanding of the complex linkages between subsystems and services and the cascading effects of one subsystem upon another, such as for example between water supply, energy production and transportation, is a significant constraint to establishing the full benefit and costs of any proposed flood risk management strategy (ibid).…”

There is a growing international recognition that flood risk management in optima forma should be a programmed and flexible process of continuously improving management practices by active learning about the outcome of earlier and ongoing interventions and drivers of change. In the Netherlands, such a long-term, adaptive flood risk management strategy is now being implemented. This so-called second Delta Programme aims to identify and exploit opportunities and capitalize on short-term benefits and opportunistic synergies that arise from change and will require adaptive policymaking. It also requires the financial and institutional means to operate in a long-lasting way, which at the very least, means engaging stakeholders, gathering and disseminating results and adaptation of future plans. Transferring the Dutch approach to other countries is a major challenge that calls for fundamental changes in institutional arrangements at various levels and thus requires customized programmes for strategic institutional change. Recent examples of transfer will provide important lessons of how institutional change can

“…A city is a complex system with many a constituent subsystems and multiple interactions between those subsystems and the city's outer environment (Zevenbergen et al, 2010;Serre et al, 2011). Consequently, risk analysis methods used in industry to identify risks and model complex system functions are considered relevant for modelling and analysing how a crisis-stricken city operates (Baroth et al, 2013;Modarres, 1993).…”

Abstract. The experience feedback on a crisis that hit a city is frequently used as a "recollection" tool. To capitalize information about an experience feedback from the cities that have been affected by a natural hazard, the authors propose in this study a functional model to model scenarios of city crises. In this model, the city, considered as a complex system, was modelled using a functional analysis method. Based on such modelling, two risk analysis methods (Failure Mode and Effect Analysis and Event Tree Method) were deployed and adjusted. Lastly, a qualitative reasoning model was used for the scenario modelling of the urban crisis. By functional modelling performed on components of the cities, the objective of this model is to replicate the behaviour of a city affected by a crisis, highlighting the sequences of failure and non-failure modes that have operated during the crisis. This model constitutes a means of understanding the functional behaviour in a crisis of cities and capitalization of the experience feedback of the cities affected by crisis. Such functional modelling was deployed in a case study.
