“…Through the domestic and foreign real water-related disaster event videos combined, it was found that the human body in the water after the accidental destabilization [33] can basically be divided into the following two states: (1) directly washed away by the current, incapable of self-rescue. (2) The friction force developed between the human body and the ground is greater than the pushing drag force of the flooding water current, and the person can remain static and stable-at this time, the primary goal of self-rescue is to recover to a standing position [33]. Therefore, this study concentrates on the self-rescue process that is employed to restore the human body to a standing position following accidental destabilization in flooding water.…”

“…Floods are one of the most common natural disasters, which affect a wider range of people than other natural disasters. Every year, floods cause huge disasters, significant economic losses, and human casualties [1,2]; Over the past decade, many studies [3][4][5]; have shown that the leading cause of death in cities during floods is related to roads, as the pathway of fast-moving flooding water. Globally, the socio-economic vulnerability to flood hazards is on the rise, as evidenced by the significant damages inflicted by recent major flooding events in various countries [6,7].…”

Human safety is paramount in flood disasters. Current research indicates that the majority of fatalities in such disasters are due to people moving in water. Existing studies on human stability in floods have primarily focused on the static resistance of a standing posture against water flow, neglecting the realistic scenario where people need to move and attempt self-rescue in the aftermath of destabilization. This paper introduces an analysis of the stability during the self-rescue process following a fall in floodwaters, providing insights into the baseline risks of human impact in floods. The self-rescue process is defined as the recovery to a standing position after a fall, segmented into four postures: sitting, kneeling, squatting, and standing. Additionally, considering the significant variability of the current method (D×v water depth multiplied by flow velocity) used to assess human stability in floods, this research thoroughly investigates previously undefined parameters, including submerged volume, frontal area, wet friction coefficient, and flow resistance coefficient. This leads to the development of a physically meaningful self-rescue risk assessment formula, which is validated against previous studies for accuracy, with the aim of contributing new insights to flood risk management and public education.

Abstract. With unprecedented growth in disaster risk, there is an urgent need for enhanced learning and understanding of disasters, particularly in relation to the trends in drivers of increasing risk. Building on the disaster forensics field, we introduce the post-event review capability (PERC) methodology for systematically and holistically analysing disaster events, and identifying actionable recommendations. PERC responds to a need for learning about the successes and failures in disaster risk management and resilience, and uncovers the underlying drivers of increasing risk. We draw generalisable insights identified from seven applications of the methodology to date, where we find that across the globe policy makers and practitioners in disaster risk management face strikingly similar challenges despite variations in context, indicating encouraging potential for mutual learning. These lessons highlight the importance of integrated risk reduction strategies. We invite others to utilise the freely available PERC approach and contribute to building a repository of learning on disaster risk management and resilience.
