Abstract

The instability caused by global warming and the spatial complexity of land surface structures is increasingly affecting basin floods. The aggregated old Xin’anjiang model can no longer simulate precise land surface information, which in turn compromises flood simulation performance. This study selects a typical representative area—the Lalin River basin in Jilin Province, China—as the experimental zone. Based on detailed land surface data and long-term hydromete-orological records, a distributed Xin’anjiang model that incorporates land surface influences is constructed. Flood simulation is performed using the multi objective evolutionary algorithm NSGA-II to analyze the flood-risk processes, trends, and magnitudes in this basin. Results show that the relative errors of the simulated flood peak and total runoff are within acceptable ranges, and the model exhibits high Nash efficiency, making it suitable for basin flood forecasting needs. The findings provide a theoretical basis for real-time dynamic flood assessment and water resource management in the Lalin River basin of Jilin Province, and they also offer insights for hydrological forecasting in similar cold-region basins of Northeast China, thereby contributing valuable guidance for mitigating flood disasters.
