It is anticipated that climate change will significantly affect flood frequencies, with more frequent and intense floods likely to occur in many parts of the world. Geospatial modeling can be used to assess possible effects of climate change on flooding frequencies, providing valuable information for flood risk management and adaptation planning. The chapter depicts the current state of knowledge on the use of geospatial modeling to assess the climate change impact on flood frequencies. It discusses the key mechanisms through which climate change can affect floods, the range of geospatial modeling approaches that can be used to assess the impact of climate change on flood frequencies, and the challenges and limitations of using geospatial modeling for this purpose. A case study was included in the chapter to demonstrate the use of advanced geospatial technique to access the impact of climate change on flood frequencies. The chapter concludes by discussing the future directions for research on the use of geospatial modeling to assess the climate change impact on flood frequencies. This includes the development of more sophisticated modeling approaches, the use of ensemble modeling to account for uncertainty, and the integration of geospatial modeling with other risk assessment tools.
