Abstract

The increase in flood events due to climate change leads to significant loss of connectivity and heightens the vulnerability of several areas, disrupting infrastructure and isolating communities. Therefore, there is a need for methods and tools to assess accessibility and enable timely action to mitigate the impacts. This research aims to develop a model to assess accessibility to infrastructure facilities during flood scenarios of varying severity, using data from hydrological models, road networks, and Geographic Information System (GIS) analysis. The model evaluates three infrastructure facilities types: resources (e.g., pharmacies), equipment (e.g., fire departments), and health facilities (e.g., hospitals), by developing and using two indices to support local decision-making during floods. The method is applied in the transboundary Axios River at north Greece. The results highlight significant accessibility reduction to infrastructure facilities at different spatial levels and particularly in specific settlements and municipalities under moderate to extreme flood events.

气候变化导致洪水事件增加，造成连接性严重丧失，加剧了一些地区的脆弱性，破坏了基础设施，孤立了社区。因此，需要有方法和工具来评估可达性，以便及时采取行动减轻影响。本研究旨在开发一个模型，利用水文模型、道路网络和地理信息系统 (GIS) 分析的数据，评估在不同严重程度的洪水情况下基础设施的可达性。该模型评估了三种基础设施类型：资源（如药房）、设备（如消防队）和卫生设施（如医院），通过开发和使用两种指数来支持洪水期间的地方决策。该方法应用于希腊北部的跨界阿克索斯河。结果表明，在中度至特大洪水事件中，不同空间级别的基础设施，尤其是特定居住区和城市的基础设施的可达性明显降低。

期刊介绍： The International Journal of Disaster Risk Reduction (IJDRR) is the journal for researchers, policymakers and practitioners across diverse disciplines: earth sciences and their implications; environmental sciences; engineering; urban studies; geography; and the social sciences. IJDRR publishes fundamental and applied research, critical reviews, policy papers and case studies with a particular focus on multi-disciplinary research that aims to reduce the impact of natural, technological, social and intentional disasters. IJDRR stimulates exchange of ideas and knowledge transfer on disaster research, mitigation, adaptation, prevention and risk reduction at all geographical scales: local, national and international. Key topics:- -multifaceted disaster and cascading disasters -the development of disaster risk reduction strategies and techniques -discussion and development of effective warning and educational systems for risk management at all levels -disasters associated with climate change -vulnerability analysis and vulnerability trends -emerging risks -resilience against disasters. The journal particularly encourages papers that approach risk from a multi-disciplinary perspective.
