Introduction:Conceptual hydrological models are useful tools to support catchment water ***,the identifiability of parameters and structural uncertainties in conceptual rainfall-runoff modeling prove to be a difficult ***,we aim to evaluate the performance of a conceptual semi-distributed rainfall-runoff model,HBV-light,with emphasis on parameter identifiability,uncertainty,and model structural ***:The results of a regional sensitivity analysis(RSA)show that most of the model parameters are highly sensitive when runoff signatures or combinations of different objective functions are *** based on the generalized likelihood uncertainty estimation(GLUE)method further show that most of the model parameters are well constrained,showing higher parameter identifiability and lower model uncertainty when runoff signatures or combined objective functions are ***,the dynamic identifiability analysis(DYNIA)shows different types of parameter behavior and reveals that model parameters have a higher identifiability in periods where they play a crucial role in representing the predicted ***:The HBV-light model is generally able to simulate the runoff in the Pailugou catchment with an acceptable *** parameter sensitivity is largely dependent upon the objective function used for the model evaluation in the sensitivity *** frequent runoff observations would substantially increase the knowledge on the rainfall-runoff transformation in the catchment and,specifically,improve the distinction of fast surface-near runoff and interflow components in their contribution to the total catchment *** results highlight the importance of identifying the periods when intensive monitoring is critical for deriving parameter values of reduced uncertainty.
