| Summary: | To reduce the average bandwidth of the forecast interval while increasing the interval coverage,this paper conducted a coupling analysis of dual EnKF and GLUE,two methods to research the hydrological model uncertainty and obtained the dual E-G method.Taking the Xin'anjiang model as an example,the paper used three evaluation indicators (i.e.,coverage,average bandwidth and average asymmetry) to evaluate the interval properties of the dual E-G method in three river basins (i.e.,the Jiahe Basin,Tianhe Basin and Bahe Basin) and compared the proposed method with the GLUE method.The results show that the dual E-G method can improve three kinds of uncertainty indexes at the same time.The results can provide a useful reference for further study on hydrological model forecasting and flood decision-making risk analysis. |
