Assessment of flood risk using space technology in Matuga state, Kenya’s coastal area
Flooding poses significant environmental, social and economic challenges globally. With ever-increasing, weather extremes induced by climate change, flooding becomes frequent and severe, particularly in coastal regions like Matuga state in Kenya. Therefore, this study assesses flood risk and its spatial distribution focusing on the interplay between land use land cover, elevation, slope, soil type and rainfall. Using remote sensing data and GIS techniques, a flood risk map for Matuga was generated to identify vulnerable zones. The result signifies that poorly vegetated areas combined with steep topography and high rainfall intensity are key contributors to flooding. Conversely, areas dominated by Ferralic Arenosols and Dystric Arenosols coupled with low slope and extensive shrub cover exhibit lower flood risks. The findings of this study provide critical insights for policymakers, urban planners and environmental managers in designing sustainable flood mitigation strategies. This study underscores the importance of integrating sustainable land management and land use planning in flood risk management for climate-resilient development in Matuga, Kenya.
