ABSTRACT
To deliver the correct messages at the appropriate time, risk communication requires an understanding of the audience. This chapter examines communication with the public and the key elements necessary for the effective delivery of impactful information about sea-level rise and flooding, adaptation, and resilience. Specifically, this chapter focuses on the audience’s communication preferences regarding information about flooding delivered through a warning or alert system. A mock flood alert system that would send flood alerts for projected high water levels was developed. Research participants were asked to interact with the mock flood alert system and to respond to specific questions about their preferences for flood alerts. The findings from our research highlight the factors that drive the use of information and offer specific approaches for communicating information and encouraging action. The research has practical implications for the design and development of alert systems and includes offering residents different options for identifying relevant risks; understanding the importance of explaining the utility, applicability, and limitations of any alert system to users; and conducting audience analysis to ensure effectiveness when alerts or warnings are provided to audiences via these systems.
