Abstract: Abstract Enhancing the capacity and awareness of individuals in disaster prevention and mitigation requires an intuitive and comprehensible method for representing flood hazard education knowledge. To address the challenges of complex information transfer and limited knowledge expression in flood disaster education, this paper proposes a novel strategy. The approach utilizes conceptual graphs to organize and guide the visual representation of flood disaster knowledge. It involves connecting flood data and knowledge elements using concept nodes and relationships, and translating them into dynamic visual representations through instantiation methods. A prototype system was developed to visualize disaster data obtained from flood-affected areas. The visualization output was compared to expert-based reports using a questionnaire, focusing on attractiveness and comprehensibility. The results demonstrated the superiority of our approach, with higher scores of 0.433 and 0.22 (on a scale of 0–1) for attractiveness and comprehensibility, respectively. This highlights the effectiveness of our approach in displaying flood knowledge and facilitating its dissemination. In summary, this paper introduces a comprehensive and dynamic visualization approach for the entire flood process, integrating relevant disaster knowledge. It presents a fresh perspective on digital disaster education tailored to floods, aiming to enhance public awareness of flood risk prevention.
