Hydrological models have been believed a useful tool in environmental change study and water resources assessment.Taking six typical river catchments in Shanxi Province as cases, suitability of RCCC-WBM model has been investigated. The resultsshow that the model could well simulate seasonal pattern of annual runoff and its decadal variation features. Nash-Sutcliffe coefficientsof the RCCC-WBM model are greater than 65% while relative errors of water volume are less than 2% for monthly dischargesimulation of the six river catchments. RCCC-WBM model is suitable to Shanxi Province, and could be applied to scientificresearch on water resources assessment.
