This study employs advanced geospatial analytical techniques to evaluate the vulnerability
of Nigeria’s coastal states and their constituent local government areas to flood hazards, which
represent a critical and escalating risk within the coastal hazard paradigm intensified by climate
change phenomena. The study’s objective is to utilize geospatial data to delineate and quantify the
intensity and distribution of flood susceptibility, thus establishing a foundational framework for
developing comprehensive disaster management strategies in response to the challenges posed by
climate variability. The research uses satellite imagery and geographic information system (GIS)-
based hydrological modeling to delineate regions susceptible to flooding, synthesizing topographical
and hydrological data to stratify areas into discrete flood susceptibility categories. The findings
indicate that the Delta coastal State of Nigeria contains extensive medium to high-risk flood zones
spanning 8304.57 km2. While the Bayelsa coastal State of Nigeria presents critical areas at high to
very high flood risk, encompassing 5506.61 km2 at high risk and 1826.88 km2 at very high risk, this
highlights the urgent necessity for immediate and strategic mitigation measures. This research highlights
the critical importance of geospatial technology in shaping disaster management and enhancing
community resilience against increasing flood frequencies. As Nigeria’s coastal regions face escalating
flood susceptibility, advanced geospatial methods are vital for assessing and mitigating
these climate-induced threats, contributing to climate-resilient planning and aligning with Sustainable
Development Goal 13: Climate Action. The study’s geospatial approach delivers precise flood
risk evaluations and guides targeted mitigation efforts, marking significant progress in managing
coastal hazards in a changing climate.
