Abstract

Flood forecasting presents significant challenges in hydrology, often addressed through flood inundation mapping (FIM), which delineates the areas likely to be inundated by floods of specific magnitudes. Additionally, effective flood risk communication is crucial for facilitating informed public decision-making. It is important that the flood maps provided to the public differ markedly from those utilized by professionals to be able to effectively communicate relevant information to specific communities. Preliminary user interviews have highlighted a widespread lack of understanding of flood inundation maps and their practical use. The primary goal of FIM is to enhance community response to flood risks. However, Alabama currently lacks a comprehensive, user-friendly FIM tool for public access, limiting communities' ability to respond effectively. This project aims to identify the most effective strategies for communicating flood risk information to Alabama communities, drawing on existing research in flood risk communication. Using the FLDPLN model to develop flood inundation maps, the project will implement an interactive ArcGIS dashboard specifically tailored for Alabama residents.
