요약Floods in large watersheds such as the Mississippi River Basin (MRB) cause significant infrastructure damage, economic losses, and social disruption. These floods result from complex interactions between large-scale storm systems and basin-specific physical characteristics. Traditional probable maximum precipitation (PMP) or precipitation frequency analysis (PFA) methods struggle to extrapolate beyond historical records and to capture the complex space-time structures of storm systems, limiting their effectiveness for current and future hazard assessment in large river basins. This dissertation presents probabilistic methods to enhance precipitation and flood hazard assessment in large river basins under a changing climate. This work first develops a storm tracking method to identify large-scale storm systems from reanalysis and global climate model (GCM) simulations. It then introduces the Space-Time Nonstationary Rainfall Model for Large Area Basins (StormLab), a stochastic rainfall generator that produces thousands of years of high-resolution (6-hour, 0.03°) synthetic precipitation scenarios for the MRB, conditioned on GCM large ensembles. StormLab explicitly models storm spatiotemporal patterns and integrates climate change impacts by leveraging GCM projections. These synthetic precipitation scenarios are integrated with hydrologic modeling and extreme value analysis to investigate flood-generating mechanisms and their frequencies in the MRB.  Validation against observational data confirms that StormLab, combined with hydrologic modeling, reproduces annual maximum precipitation and flood peaks in the MRB. The analysis reveals an increasing trend in Lower Mississippi flood hazards under future climate scenarios, which is not only caused by intensified individual storms, but by the combined effects of extreme storm clustering. The proposed methods are further adapted to estimate probabilistic PMP and its changes under future climate conditions for a critical dam in the MRB. This work demonstrates the value of leveraging GCM large ensembles to extend limited historical records, reduce uncertainties, and enhance understanding of flood hazard processes, providing a robust framework for future hazard and risk assessments.
