Flooding is a frequent and devastating natural disaster, especially in coastal regions where geographic and climatic factors heighten its occurrence. This study focuses on flood risk mapping in Nagari Sungai Liku Pelangai and Nagari Tuik IV Koto Mudik, areas severely affected by a flood on March 7, 2024. Using Geographic Information Systems (GIS) and a scoring system, the research assesses flood vulnerability based on factors like land type, slope, soil characteristics, and rainfall patterns. The findings show that 90.96% of Nagari Sungai Liku Pelangai and 92.98% of Nagari Tuik IV Koto Mudik are classified as low-risk areas. However, smaller but critical areas—3.4% and 4.38%, respectively—are high-risk and overlap with densely populated zones. These results highlight the urgent need for targeted mitigation strategies and improvements in disaster preparedness. Additionally, the study integrates community feedback, revealing that inadequate disaster infrastructure and low public awareness further exacerbate the regions’ vulnerability. By combining quantitative spatial analysis and qualitative insights, this research provides comprehensive flood risk maps that inform better resource allocation and enhance early warning systems. These findings are crucial for improving flood management in vulnerable rural coastal areas. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2026.
