Toward optimum multiple objective model calibrations for AWRA-L model

[摘要] This report summarises 15 weight modelling experiments on multi-objective regional model calibration for the AWRA-L model. The model calibration and validation results show that the daily runoff simulation is not sensitive to weight when it varies from 1.0 to 0.1. Putting lower weights on daily runoff shows only slight degradation or similar performance to putting higher weights on it. The modelling experiment also shows that soil moisture plays a more important role than leaf area index in improve runoff predictions. A best compromise of the three objective functions is a weight of 0.4 for runoff and that a weight of 0.3 for each of leaf area index and soil moisture can be used for guiding the AWRA-L model multi-objective calibrations.
