Climate change and increasing global temperatures are leading to more severe, prolonged, and frequent flood disasters making effective risk communication crucial. This communication promotes a shift from traditional engineering-focused flood defence strategies to comprehensive, risk-based management approaches, thereby making risk perception a prerequisite in effective risk communication. Maps are essential for detailing, analysing, and synthesising the phenomena leading to natural disasters, serving to raise awareness, regulate urban planning, and provide expert insights for both prevention and prediction. Using randomised controlled trials, this study carries out surveys across the UK and Pakistan. Participants are presented with a hypothetical residential coastal area, with and without flooding information, to indicate their residential and behavioural preferences. Five different scenarios are used, each with the same information presented differently. Implications of the study elucidate public preferences and flood risk perception.
