Abstract: The Liuxihe Model is a physically based distributed hydrological model for catchment flood forecast.The trial-and-error method has been used in parameter optimization of the model,though it can gain a good result,it is complex and lowly efficient.In this paper,a case study of the Liuxihe River Reservoir catchment in Guangzhou is made,in which SCE-UA algorithm is used for parameter optimization.The result shows that the algorithm can process the parameter optimization of the Liuxihe Model rapidly and effectively.As compared with the trial-and-error method,the algorithm is much more simple,convenient and high-effective,and applicable to the distributed hydrological model.
