摘要：

A physically-based semidistributed model, TOPMODEL, is applied to a 340 hectare spruce forested catchment in mid-Wales. The model is calibrated to runoff and the subsurface flow is divided into components of flow identified by depth of origin. In addition, chemical mixing techniques are used to provide a hydrograph separation between acidic soil waters and well buffered deep waters. The short-term variations in the components of flow identified by these two approaches compare well.
