Summary A distributed rainfall-runoff model was developed to predict storm runoff from humid forested catchments. The model is physically based and takes into account ments, Infiltration, overland flow and lateral subsurface flow are estimated, while on channel flow elements river flow routing is performed. Lateral subsurface flow is calcu-model calibration. The model is tested using nine storm events in the Jiaokou watershed, a sub-basin of Yongjiang River in Zhejiang Province, China. Of these storms, one storm is used for calibrating the model parameters and the remaining eight storms are used to ver-ify the model. When judged by the model efficiency coefficient (R2), volume conversation index (VCI), absolute error of the time to peak (DT), and relative error of the peak flo
