Chapter 7. Integrated Asset Management for Extreme Disasters: Assessing the 2023 Flood Events and Resilience of Critical Infrastructures Available to Purchase

The global community is currently witnessing many casualties and economic losses resulting from extreme weather and climate-related disasters, particularly floods. These occurrences have become more pronounced in terms of their intensity and frequency due to climate change. In 2023, many countries experienced devastating floods and heavy rainfall, and the problem is further exacerbated by humanity’s increasing reliance on critical infrastructure and essential assets, which will lead to increased susceptibility to situations classified as 'extreme occurrences'. Therefore, it is imperative to prioritize the development of climate-resilient non-structural and structural means to enhance the effectiveness of water governance.

This study assesses the extreme flood disasters in 2023 and investigated a more integrated flood management approach using risk-informed based method. Additionally, the study aims to enhance the resilience of critical infrastructure to mitigate the impact of future disruptive flood disasters. Technical development that echoes the principle of adopting new information is incorporated into the methodology to improve the resilience. To effectively implement a flood management strategy based on risk assessment, it is essential to have a comprehensive understanding of the risk patterns in a floodplain and to determine the key factor that requires prioritization to mitigate the risk.

The findings indicated a need to explore strategies that is necessary for adapting to evolving environmental, hydrological, and social conditions, which builds sustainable resilience. To facilitate socioeconomic growth, water resource infrastructure needs to be proliferated to meet increasing current realities.

In a climate-change-affected world with massive floods, preparation is crucial. We need resilience and green infrastructure that can be adapted to various disasters. This vital research develops sophisticated decision-support tools and builds resilience to help managers and decision-makers. Thus, identifying, assessing, and implementing appropriate structural and nonstructural interventions would reduce damages and enhance future flood planning, resulting in significant economic, social, and environmental benefits.
