Flood Risk Analysis and Assessment, Applications and Uncertainties: A Bibliometric Review

Abstract

Studies looking at flood risk analysis and assessment (FRA) reviews are not customary, and they usually approach to methodological and spatial scale issues, uncertainty, mapping or economic damage topics. However, most of these reviews provide a snapshot of the scientific state of the art of FRA that shows only a partial view, focused on a limited number of selected methods and approaches. In this paper, we apply a bibliometric analysis using the Web of Science (WoS) database to assess the historic evolution and future prospects (emerging fields of application) of FRA. The scientific production of FRA has increased considerably in the past decade. At the beginning, US researchers dominated the field, but now they have been overtaken by the Chinese. The Netherlands and Germany may be highlighted for their more complete analyses and assessments (e.g., including an uncertainty analysis of FRA results), and this can be related to the presence of competitive research groups focused on FRA. Regarding FRA fields of application, resilience analysis shows some growth in recent years while land planning, risk perception and risk warning show a slight decrease in the number of papers published. Global warming appears to dominate part of future FRA production, which affects both fluvial and coastal floods. This, together with the improvement of economic evaluation and psycho-social analysis, appear to be the main trends for the future evolution of FRA. Finally, we cannot ignore the increase in analysis using big data analysis, machine learning techniques, and remote sensing data (particularly in the case of UAV sensors data).

Mitigation of Urban Pluvial Flooding: What Drives Residents’ Willingness to Implement Green or Grey Stormwater Infrastructures on Their Property?

“…Since the turn of the new millennium, an increasing strand of the social science literature has explored citizens' flood risk perception [19] and their awareness and willingness to implement adaptive actions. These include protective/preparedness measures-actively adopted during a flood event-and mitigation measures-i.e., passive actions implemented before the event, preventing or limiting its adverse consequences [20,21].…”

Tidal Flood Risk on Salt Farming: Evaluation of Post Events in the Northern Part of Java Using a Parametric Approach

“…Other physical conditions such as geological features, soil types, topography, and coastal slopes have less implications for salt farming vulnerability. Although several studies suggest that elevation and slope elements have a substantial impact on coastal vulnerability assessment (CVA) [109][110][111], we argue for considering other parameters in further research, such as the shoreline change range [112,113] and rates of sea-level rise, the latter being a global phenomenon that will increasingly impact agricultural activities in coastal areas throughout the world [114,115].…”

Floods in Spain’s Mediterranean region: causes and effects

“…Evidence of the interest that floods arouse in the world are the review publications that have been made in recent years (Ologunorisa et al, 2005;Cheng et al, 2010;Salman and Li, 2018;Lindersson et al, 2020;Díez-Herrero andGarrote, 2019, 2020). The bibliometric analysis on a world scale by Díez-Herrero and Garrote (2020), using the Web of Science database, to evaluate the historical evolution and future perspectives of the flood risk assessment, shows how the scientific production on the analysis of flooding has increased considerably in the last 25 years.…”
