Short summary
The spatial resolution of hydrological modeling is a critical factor affecting flood simulation accuracy, particularly in large watersheds with complex characteristics. This study quantifies the impact of spatial resolution on hourly flood simulation and identifies flood characteristics that are sensitive to spatial resolution. The findings provide practical guidance for selecting appropriate spatial resolutions in large-watershed modeling.
