This work aims to offer a contribution in the analysis and management, from an economic and financial point of view, of the flood risk, and extended to the hydrogeological risk, from the perspective of a public administration. As main responsible actor for containing the phenomenon through the maintenance of the territory, public administration is responsible for the cost of restoring of the services that have been damaged by this type of phenomenon. The assets of which the public administration must ensure the restoration are all public infrastructures (i.e. transportation, energy and water supply system, communication) together with the damage suffered by private property, if these affect services to be guaranteed to the population. In this work, the authors propose possible strategies that a public administration can put in place to deal with flood risk. Three main strategies are analysed: an absolute passivity that provides for the payment of damages as they occur (i.e. business-as-usual scenario), a classic insurance scheme, a resilient and innovative insurance scheme. The economic–financial profiles of these strategies proposed in this work put an emphasis on how the assumption of a time horizon can change the convenience of one strategy compared to the others. This study highlights the key role of the quantification of flood risk mitigation measure from an engineering perspective, and their potential issues to pursue these objectives in connection to the regulatory framework of the public administrations. This synergy is supported by the potential use of Blockchain-based tools. Within the paper is highlighted the key role that such platform IT data management platform could have within risk analysis and management schemes, both as a data collection tool and as certification of the various steps necessary to complete the process.

这项工作旨在从经济和金融角度为洪水风险的分析和管理做出贡献，并从公共行政的角度扩展到水文地质风险。作为通过维护领土来遏制该现象的主要责任方，公共管理部门负责恢复已被此类现象损坏的服务的费用。公共行政必须确保恢复的资产是所有公共基础设施（即运输，能源和供水系统，通讯），以及私有财产遭受的损害，如果这些损害了向人民提供的保障服务。在这项工作中，作者提出了可能的策略，公共管理部门可以采取适当的策略来应对洪水风险。分析了三种主要策略：绝对被动性，可以在发生损害时（即照常营业）支付损害赔偿；经典保险计划；弹性和创新性保险计划。在这项工作中提出的这些策略的经济-财务概况强调了时间跨度的假设如何可以改变一种策略相对于另一种策略的便利性。这项研究从工程角度突出了量化洪水风险缓解措施的关键作用，以及与公共行政管理框架相关的实现这些目标的潜在问题。潜在使用基于区块链的工具可支持这种协同作用。
