The flood invasion process, invasion time, and spread pattern of subway stations under various operating conditions were analyzed. Moreover, suggestions for human evacuation within the station were proposed. The results indicate that the closed tunnel floodgate causes an increase in water collection in the subway station. While opening the tunnel floodgate can efficiently relieve flood pressure in the subway station, it is critical to avoid floods pouring through the tunnel to the next station. The increase in water depth and water inlet number led to an increase in the water velocity intrusion into the subway station, resulting in a rapid increase in the water depth in the subway station, and pedestrians ought to evacuate the subway station as soon as possible. The research findings are intended to serve as a reference for the safe evacuation of people when floods invade subway stations.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"114 ","pages":"Article 104984"},"PeriodicalIF":4.2,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142705125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A notable example is Cyclone Belal, which struck Mauritius on January 2024, during high tide, causing extensive infrastructure damage. This underscores the importance of conducting risk assessments to identify vulnerable areas and develop risk reduction strategies. However, quantitative risk assessments of storm tides are often challenging due to the lack of long-term projections. To address this, we developed a GIS-based flood model for Mauritius to simulate inundation areas and quantify the assets exposed to flooding. Under current conditions, the estimated damage exposure from extreme coastal flood events with return periods of 50–500 years is significant, with 6.2 % and 27.1 % of the area inundated, respectively. By 2100, damage exposure associated with these events is projected to increase by a factor of 1.1, with minimal variation between sea-level rise scenarios (0.3m). However, by 2200 and 2300, damage exposure is expected to rise by factors of 3.1 and 6.6, respectively. In the worst-case scenario for 2500, Mauritius could experience maximum inundation of 66.3 km<sup>2</sup>, with buildings covering 5.02 km<sup>2</sup> submerged. Additionally, this study presents a detemporalized inundation scenario to assess impacts from any coastal flood event. This approach enables the identification of critical thresholds (1.5 m and 4.5 m) and, beyond which significant increases in damage exposure are likely, and allows for evaluating adaptation strategies against user-defined levels of change, rather than relying solely on predefined scenarios.

Addressing this burning issue, a geospatial technology-based case study of the Kohima district, Nagaland state (India), is presented here. The geospatial \"technology-based\" analyses employed in the study are thematic GIS mapping of flood hazard, vulnerability and risk controlling factors; and performing overlay operation using the AHP model in GIS software to generate spatio-temporal map layers of flood vulnerability and disaster risk. Results reveal that the region is under a high rate of monsoon climate change (increasing temperature, rainfall, rainy days, rainfall events and flood events with an annual rate of 0.35 %, 1.12 %, 0.36 %, 2.67 % and 4 % respectively), land use degradation (increasing built-up area with 0.60 %, annual rate decreasing forest, shrubs and water bodies with 0.80 % accumulated annual rates respectively) and demographic changes (increasing urban as well and rural population density with 0.53–2.10 % and 0.55–2.14 % respectively). Accumulated impacts of climate change, land use degradation and demographic changes causing an increase in flood hazard, vulnerability and disaster risk. Flood hazard zones and vulnerability zones extending with 0.50 % (4.89 km<sup>2</sup>) and 0.84 % (8.16 km<sup>2</sup>) annual rates respectively, subsequently the flood risk zones categorized as a moderate, high and very high potential risk, have been spreading out with a yearly rate of 0.07 % (0.65 km<sup>2</sup>), 0.13 % (1.31 km<sup>2</sup>) and 0.03 % (0.33 km<sup>2</sup>) respectively.

Following up on these annual rates, the spatial distribution of flood hazard, vulnerability and risk zones for the next decade (2031–2040) have also been projected, revealing alarming situations, if flood disaster risk reduction (F-DRR) measures were not implemented in timely.

Finland serves as the case study due to its pioneering position in crisis preparedness and its adoption of a comprehensive preparedness model that encompasses relationships and interactions among diverse stakeholders. In this study, the Finnish preparedness system is illustrated and analysed through the lens of complex adaptive systems (CAS). Data are collected through interviews with security actors representing different stakeholder groups, including civil society, businesses, and the public sector. An interpretative approach synthesises insights from literature, reports, and stakeholder interactions to co-create knowledge. The analysis covers the CAS tenets of context, relational constitution, adaptive capacity, emergence, and openness. The study presents an exploratory model anchored in CAS theory, incorporating key practices, processes, and adaptation loops integral to societal resilience from a systemic perspective in the Finnish context. From a theoretical point of view, this study contributes to CAS theory by exploring the role of context as a slow-changing variable, which is often considered a constant in CAS. Furthermore, while emergent behaviour is a critical component of CAS, most studies explore the emergent behaviour of a system within a short time span. However, the findings of this study highlight the importance of long-term emergent behaviour in addition to short-term behaviour. From a practical standpoint, this study not only explores best practices but also identifies the challenges of the Finnish system and provides a benchmark for other countries to develop their own crisis preparedness.
