7.1 The efficiency of SA-MO

The study case combined LH-OAT and MOSCEM-UA for EasyDHMmodel calibration.In EasyDHM model，29 parameters were included that canbe divided into routing and underlying related categories.Zhuba catchment located in upstream of Yangtze River was chosen for hydrological modeling.

7.1.1 Sensitivity analysis

Figure 7-1 showed the global partial effect of EasyDHM parameter sensitivity against ANS and LNS.Generally，EasyDHM model was more sensitiveto LNS than ANS.Gwdelay showed the highest partial effects to LNS，followed by CN2，CH_S2M and CH_L2M.Table 7-1 listed the sensitivityranking results of EasyDHM parameters against model objectives，amongstwhich parameters CH_L2M，FieldCapM，CN2，CH_S2M and Gwdelaywere more sensitive to the criteria.However，other parameters showed comparatively l ......     （共5820字）    [阅读本文]>>
