在洪水风险日益增加的全球背景下，制定能够有效支持灾害风险管理战略和政策的风险评估至关重要。考虑到文化遗产的社会经济价值，这一点尤其重要。虽然关于文化遗产保护和减轻文化遗产自然灾害影响的专题文献很多，但此类研究的适用性通常仅限于单一资产或遗址。大空间尺度的文化遗产洪水风险评估研究较少，这与该课题的重要性形成了鲜明对比。本文提出了一种新的框架，用于对一个国家等大区域的不可移动文化遗产进行半定量洪水风险评估。所提出的框架采用了自然灾害风险领域中各种科学确立的概念，以支持为每个暴露资产计算连贯和可比的洪水风险指数。该框架可用于对大量资源有限的文化遗产资产进行初步风险评估，并确定那些需要进行更详细风险评估的文化遗产资产。该框架通过对葡萄牙大陆遭受河流洪水影响的不可移动文化遗产的应用来说明。本案例研究用于讨论与数据需求、可用性和可靠性相关的各种问题。(C) 2019 Elsevier Masson SAS。版权所有。
In a global context of increasing flood risk, the development of risk assessments that can effectively support disaster risk management strategies and policies is crucial. This is particularly relevant in the case of cultural heritage, given its socioeconomic value. Although there is a substantial body of literature on the topics of cultural heritage preservation and natural hazard impact mitigation in cultural heritage, the applicability of such studies is usually limited to single assets or sites. The assessment of cultural heritage flood risk at large spatial scales has received little research attention, which contrasts with the importance of the topic. This paper proposes a novel framework to perform semi-quantitative flood risk assessments to immovable cultural heritage assets in a large region, such as a country. The proposed framework employs various scientifically established concepts from the field of natural hazard risk in order to support the computation of coherent and comparable flood risk indices for each exposed asset. This framework can be used to provide a preliminary assessment of risk for a large number of cultural heritage assets with limited resources, as well as to identify those that warrant a more detailed evaluation of risk. The framework is illustrated through an application to immovable cultural heritage assets exposed to fluvial floods in mainland Portugal. This case study is used to discuss various issues related with data requirements, availability and reliability. (C) 2019 Elsevier Masson SAS. All rights reserved.
