“…Susceptibility is a function of various parameters such as surface elevation, slope, distance to a river, soil type, and income, to name a few [33]. A work by Goumrasa et al [33] provided a flood susceptibility assessment using GIS and AHP methods. Another study by Wang et al [34] presented a flood susceptibility mapping framework involving an adaptive neuro-fuzzy inference system with two metaheuristic methods of biogeography-based optimization and an imperialistic competitive algorithm.…”

It is a well-accepted notion that women are more vulnerable to natural disasters than men, especially in developing countries. However, in developed countries, how women’s empowerment by economic and social development has reduced the gender gap in vulnerability remains insufficiently answered. As Japan passed its golden age, moving into an aging society, a study on how the gender difference in flood vulnerability has evolved can contribute to a better understanding of the types and causes of vulnerability, leading to better flood risk management in a new social context. Following this thinking, the present study conducted a longitudinal analysis using representative flooding cases in Japan over a period of forty years. It found that the women’s fatality rate increased with age much faster than men’s in the 1980s but reversed in a recent major flood disaster. It also revealed that most flood disaster victims were elderly in recent years. These findings suggest that the flood vulnerability at present is more driven by age-related physical ability decline, much less relevant to gender. Based on the results, it proposed a new framework for assessing flood vulnerability in an aging society. Such outcomes can help with the better formulation of flood management policies and probing into solutions.

“…(4) A study on environmental sciences was to draw the past and present land utilization/land cover (LULC) [71] categories based on historical maps and remote sensing data, and then estimate the surface runoff depth of specially designed rainstorms in two periods by executing the soil conservation service curve number (SCS-CN) methodology in the ArcGIS environment, filling the gap in the research on the impact of increased surface runoff caused by human factors on flash floods in the basin. (5) A study related to civil engineering [72] was to identify the sections most vulnerable to flash flood disasters by innovatively combining a flash flood disaster map with a road chain plan. The results obtained by this method could be used to help government departments formulate protection strategies of infrastructures.…”

Meta-Analysis and Visualization of the Literature on Early Identification of Flash Floods

Flash flood is one of the extremely destructive natural disasters in the world. In recent years, extreme rainfall events caused by global climate change have increased, and flash flood disasters are becoming the main types of natural disasters in the world. Due to the characteristics of strong suddenness, complex disaster-causing factors, great difficulty in prediction and forecast, and the lack of historical data, it is difficult to effectively prevent and control flash flood disaster. The early identification technology of flash floods is not only the basis of flash flood disaster prediction and early warning, but also an effective means of flash flood prevention and control. The paper makes a meta-analysis and visual analysis of 475 documents collected by the Web of Science Document Platform in the past 31 years by comprehensively using Citespace, Vosviewer, Origin, etc. We systematically summarize the research progress and development trend of early identification technology of flash flood disasters from five key research subfields: (1) precipitation, (2) sediment, (3) sensitivity analysis, (4) risk assessment, (5) uncertainty analysis. In addition, we analyze and discuss the main problems encountered in the current research of several subfields and put forward some suggestions to provide references for the prevention and control of flash flood disasters.

“…The extent of the impact of floods includes 170 million people each year (Hagos et al 2022). On the local level, the phenomenon of floods is considered as the most dangerous geographical phenomenon that Algeria has known in recent decades (Goumrasa et al 2021). In recent years, the study of the analysis and impact of flood maps has witnessed rapid development in the analysis methodology and the strategy of extracting flood impact maps (Hu et al 2017).…”

Flooding is one of the most devastating natural disasters brought on by climate change in North Africa. The occurrence of flood risk is due to a combination of natural and man-made variables, necessitating a better knowledge of its spatial scope. The goal of this study is to locate and map flood-prone regions in the Cheliff-Ghrib watershed. Within the ArcGIS interface, this study is based on the integration of multi-criteria data such as slope, drainage density, type of soil, rainfall, population density, land use and sewer system density. For flood risk assessment and mapping, the Analytic Hierarchy Process (AHP) technique was employed as a multi-criteria analysis, allowing the integration of numerous factors under two criteria namely, hazards and vulnerability. The AHP flood risk map reveals that areas at high and extremely high risk of flooding cover 22.5% of the study area. According to the findings, the Cheliff-Ghrib watershed is extremely vulnerable to flooding. Eight of the Chelliff-Ghrib watershed's 15 municipalities (8/15) are at high risk of flooding, necessitating the development of efficient flood mitigation solutions for future flood events.
