| Abstract: | Objective functions and parameter optimization algorithms for conceptual hydrological model calibration were introduced firstly. By using observed hourly rainfall and discharge data of Qiyi Reservoir basin in Jiangxi Province, the parameter space and the parameter sensitivity of the Xinanjiang model were analyzed deeply. The multi-objective functions and their combination as well as the solutions were also discussed in detail. It was found that automatic calibration using multiple objectives could consider of different aspects of the discharge hydrograph and has a better goodness-of-fit than that of the traditional single objective function. |
