The Coupled Model Intercomparison Project Phase 6 (CMIP6) represents the latest advancement in climate modeling, providing improved simulations of Earth system processes and future climate projections under shared socioeconomic pathways (SSPs). This chapter presents a comprehensive overview of CMIP6 models and SSP scenarios, with a focus on their application in hydrological assessments. It discusses projected changes in key climatic variables and their implications for streamflow, groundwater recharge, evapotranspiration, and water resource sustainability. The chapter also highlights methodological challenges, uncertainties, and future research directions, emphasizing the need for integrated modeling approaches in climate impact studies.en-USCMIP6SSP ScenariosClimate ModelsHydrological CycleClimate ChangeWater ResourcesBook chapter
