Abstract:
Climate change is It stands among the most significant challenges confronting the world today. In recent years, the problem of climate change has evolved from a narrowly focused scientific concern, relevant to a limited group of researchers, into a top priority on the global political agenda. Among the most significant impacts of climate change are the increasing recurrence and intensity of floods, resulting from changes in precipitation patterns and snowmelt, as well as rising sea levels that threaten coastal areas. Although Iraq contributes only a small fraction to global greenhouse gas and carbon dioxide emissions, It is classified among the countries most affected by Changes in climate patterns. This study aims to provide a comprehensive review of the Methodologies and techniques used for flood risk analysis and prediction, utilizing Global Climate Models (GCMs) under Shared Socioeconomic Pathways (SSPs) scenarios. The study emphasizes the integration of projected climate data into
the development of hydrological models, highlighting the importance of bias correction techniques to increase the accuracy of climate models. The results of this study contribute to the improvement of effective strategies for flood risk management and planning for adaptation to future climate change.
Keywords: Global Climate Models, Bias Correction, Coupled Model Intercomparison Project Phase 6, Flood Risk Analysis.
