“…Two different methodologies were predominantly used in sketch map assessments and this was the case for studies which analyzed individuals' perceptions of natural risks. In the first case, individuals' sketch maps were analyzed by compilation (Brennan et al 2016;Brilly and Polic 2005;DeChano and Butler 2001;Gaillard 2008;Gaillard et al 2001;Leone and Lesales 2009;Pagneux et al 2011;Ruin et al 2007). The aim of this methodology is to capture a collective perception of hazardous areas.…”

“…The aim of this methodology is to capture a collective perception of hazardous areas. Studies often compared an expert estimation of hazardous areas with the collective perception (Brennan et al 2016;Pagneux et al 2011;Ruin et al 2007). In the second case, studies focused more on assessing sketch maps at an individual level (Cheung et al 2016;O'Neill et al 2015).…”

“…Sketch maps were also used to study the changing perceptions of youths after their transition from a university neighborhood to a university campus (Pearsall et al 2015) or to investigate students' knowledge of libraries (Horan 1999) Several studies about individuals' perceptions of natural hazards have also used sketch maps. Thus, they have been used to capture individuals' perception of landslide risk (DeChano and Butler, 2001) volcanic risk (Gaillard 2008;Gaillard et al 2001;Leone and Lesales 2009), flood risk (Brennan et al 2016;Brilly and Polic 2005;O'Neill, Brennan et al 2015;O'Neill et al 2016;Pagneux et al 2011;Ruin et al 2007) and coastal flood risk (Cheung et al 2016). Gueben-Venière (2011), Chevillot-Miot (2017) and Chionne (2018) also used sketch maps during interviews with stakeholders about coastal flood risk.…”

Background: This study analyzes individuals' perceptions of areas exposed to coastal flooding at a local level using sketch mapping methodology. In this way, 318 individuals were surveyed in four coastal municipalities in France (Barneville-Carteret, Saintes-Maries-de-lamer , Châtelaillon-Plage and Sainte-Anne). We assessed the disagreement between expert estimates and individuals' perceptions of areas exposed to coastal flooding using sketch mapping indicators. We also determined the relationships between individuals' living environments and the way they perceived the spatial extent of coastal flooding. Results: Respondents were likely to under-assess the exposure of areas that are actually exposed according to expert hazard maps. Perceived distance to coastal flooding areas appeared to be a predominant factor in assessing individuals' perceptions. Conclusions: Local preventive actions could take into account the individuals' tendency to underestimate the areas exposed to coastal flooding. Individual perception of the spatial extent of coastal flooding appeared to be more influenced by the perceived distance of the home to exposed areas than the objective distance. It is a result that raises the question about the individuals' understanding of hazard maps and regulatory maps. This may necessitate the improvement of the appropriation of these documents by the inhabitants by involving them more closely in the application and decision process that directly concerns.

“…In more fragmented communities, problem understandings of actors are, according to the mental model approach, expected to diverge as a result of selective, interest focused interpretation of information [31,36,37]. Accordingly, risk area residents were found to vary in the degree they differentiated mental models of environmental hazards [38] or cognitive maps of flood zones [39]. Similarly, the Faultline theory suggests a split of such communities in subgroups based on the group members' demographic alignment [40].…”

The term “risk” is connoted with divergent meanings in natural hazard risk research and the practice of risk management. Whilst the technical definition is accurately defined, in practice, the term “risk” is often synonymously used with “danger”. Considering this divergence as a deficiency, risk communication often aims to correct laypersons’ understanding. We suggest to instead treat the variety of meanings as a resource for risk communication strategies. However, there is however to date no investigation of what laypersons’ meanings of risk actually comprise. To address this gap, we examine the meanings of risk by applying a social representations approach within a qualitative case study research design. Results of the study among inhabitants of Swiss mountain villages show that differences in meanings were found according to hazard experience and community size. We found commonly shared core representations and peripheral ones. We conclude with suggestions on how to make usage of the knowledge on SR in risk communication.

“…Accounting for half of all natural disasters in the world, flooding is one of the most common and severe forms of natural disaster [9][10][11][12]. Flood events are expected to increase in frequency and intensity due to more frequent and extreme precipitation events and rising sea level [13][14][15][16]. China is a country prone to a variety of natural disasters, but flooding is the major meteorological disaster that affects many of its regions [17][18][19].…”

Abstract:The operation of flood retarding areas does not attract much attention, although they are important components of flood control systems. Poor operation of such areas restricts not only the socio-economic development of the flood retarding area, but also limits scientific flood control options. As the second-largest flood retarding area in China, with more than 2000 km 2 and 300 polders, the Hongze Lake vicinity was taken as a case study of graded flood retarding. A one and two-dimensional coupled hydrodynamic model was established to simulate flood routing in the Hongze Lake area. Fifteen different schemes involving different flood magnitudes and flood retarding operations were simulated. The results show that (1) having a flood retarding area is essential; and (2) the "graded flood retarding" scheme is superior to "no grading flood retarding" scheme; and (3) a "two-grade flood retarding" scheme is recommended.
